Short answer: Upload speed is usually slow because the plan was built that way: many cable and 5G home internet plans send far less than they receive, while fiber plans such as AT&T Fiber are symmetrical. Check your plan's upload figure first, then run a wired speed test with any VPN off. If a wired test matches the plan but Wi-Fi doesn't, the problem is in your home; if both fall well short, contact your provider.

Upload speed is usually slow because your internet plan was built that way. Many cable and 5G home internet plans send data far more slowly than they receive it; fiber plans are more often symmetrical, with equal upload and download speeds. So the first step is to find your plan’s upload figure. If a wired speed test matches it, your connection is working as sold, and the fix is a different plan or less competition for the upload you have. If a wired test falls well short, the problem is your equipment or your provider.

Upload is the data you send: your camera on a video call, photos backing up to the cloud, a live stream, footage from security cameras. Download is the data you receive. This guide covers how to tell which kind of “slow upload” you have and what to do about each. It draws on provider, FCC and manufacturer documentation.

Step 1: Check what upload speed your plan includes

Internet ads lead with download speed, so many people never see their upload figure. Look for it on your provider’s website, your bill or the broadband label for your plan. FCC rules require providers to show labels that include typical download and upload speeds and latency.

What you’ll typically find depends on the technology:

The CableLabs figures are network capacity in the specifications, shared across many homes, not the speed of any plan; CableLabs says deployed performance varies. By those figures, DOCSIS 4.0 has three to six times the upstream capacity of DOCSIS 3.1. Our DOCSIS 3.0 vs. 3.1 vs. 4.0 guide covers what each modem generation supports.

For context, the FCC’s benchmark for fixed home broadband is 100 Mbps download and 20 Mbps upload. It adopted that figure on March 14, 2024, and its 2026 broadband report, released August 14, 2026, kept it while dropping the FCC’s longer-term goal of 1 Gbps down and 500 Mbps up.

T-Mobile’s ranges also show how wide “typical” can be: for its main plans and latest gateway, it says 25% of customers see speeds below the range and 25% see speeds above it.

Step 2: Test your upload properly

A single phone test over Wi-Fi tells you little. To find where the bottleneck is:

1. Stop other uploads. Pause cloud photo and file backups and, if you can, anything else sending data, such as cameras or a game console uploading clips.
2. Turn off any VPN. Ring’s own speed-test instructions start with this step. A VPN sends your traffic through another server, so you’d be testing that route instead of your connection.
3. Test wired. Plug a computer into the router with an Ethernet cable and run a speed test.
4. Test over Wi-Fi in two places. Once near the router, then where you usually work or where the device that uploads sits. Ring suggests testing next to the router and again where its device is installed.
5. Compare with your plan. Ring tells customers to contact their provider if the test next to the router shows less than 60% of the speed they pay for.

Then read the results:

Step 3: Fix what you found

If your plan’s upload is simply too low

Add up what your household sends at the same time. Ring’s guidance gives a sense of scale for cameras: about 1 Mbps of upload for a 720p device, 2 Mbps for 1080p, 2.5 Mbps for 1536p, 10 Mbps for 2K and 15 Mbps for 4K. Three 1080p cameras uploading at once would use about 6 Mbps by that measure, which is a large share of a plan with 10 Mbps of upload. Our guide to how much internet speed you need has figures for video calls and other uses.

If the total is close to your plan’s upload, the options are a higher tier, a different technology if one is available at your address (AT&T, for example, says its fiber has equal upload and download speeds), or scheduling large uploads such as backups for overnight.

If uploads make everything else lag

When an upload fills your connection, video calls and games can stutter even though downloads look fine. That’s often bufferbloat: data queues up in the router or modem and delays everything behind it. Our bufferbloat guide explains how to test for it and which router settings, such as smart queue management, help.

If only Wi-Fi uploads are slow

The problem is between your device and the router, not your internet connection. Try the same fixes as for slow Wi-Fi in general: move closer or move the router to a central spot, use the 5 GHz or 6 GHz band near the router, and update the device’s Wi-Fi drivers. Our guide to why Wi-Fi is slow when the internet is fast walks through it. For a device that uploads constantly, such as a desktop PC used for streaming, a wired connection removes Wi-Fi from the equation.

If even wired uploads fall short

Restart the modem and router, then test again. Check that your modem supports your plan; on cable, the DOCSIS guide linked above lists the upload limits Netgear gives for each modem generation, and your provider’s list of approved modems shows what it supports. If a wired test with nothing else running still falls well short of your plan, contact your provider with your test results, including the time and whether the test was wired.

Bottom line

Start with your plan’s upload number, not your router settings. Many plans, especially on cable and 5G home internet, are built with slow upload, and no setting changes that. If your wired results match your plan, the fix is a different plan or less competition for upload; if Wi-Fi alone is slow, fix your home network; if wired results fall short too, take it to your provider.

Sources and verification

Short answer: Wi-Fi that keeps dropping has three possible sources: one device, your router, or your internet connection. If only one device drops, check its power-saving, driver and network settings. If every device drops, look at the router: signal, band steering, DFS channels, firmware and heat. If the router stays up but the internet goes down, check for a provider outage.

When Wi-Fi keeps disconnecting, the cause is almost always in one of three places: a single device, your router, or your internet connection. The quickest way to narrow it down is to check whether one device drops or all of them do, then whether a computer plugged into the router with Ethernet drops too. This guide walks through that check, then the fixes Apple, Microsoft, Google and router makers recommend for each case.

It’s built from manufacturer and FCC documentation. Menu names vary by device and software version, so use these as a guide to what to look for.

First: is it one device, all devices, or the internet?

Microsoft, Google and Apple all suggest trying another device on the same network. If the other device stays connected, the problem is probably the first one. Apple adds that if you can’t get online using your other devices, “there might be a service outage,” and you should contact your provider.

A simple way to sort it out:

On Windows, you can also ping the router. Microsoft suggests running ipconfig to find the “Default gateway” address and then pinging it. Microsoft says replies mean there might be a problem with your modem or provider. If there are no replies, it suggests plugging the PC straight into the modem with Ethernet: if that works, the router is likely the problem.

If only one device keeps dropping

Windows laptops and PCs

Microsoft’s Windows 10 and 11 guide lists these fixes:

• Stop Windows switching off the adapter. In Device Manager, open Network adapters, open your Wi-Fi adapter’s Properties, and on the Power Management tab clear Allow the computer to turn off this device to save power. In the advanced power plan settings, set Wireless Adapter Settings > Power Saving Mode to Maximum Performance.
• Reinstall the driver. In Device Manager, right-click the adapter, choose Uninstall device, tick Attempt to remove the driver for this device, then restart. Windows reinstalls it. Intel, which makes many laptop Wi-Fi adapters, says “you can remedy many problems by updating drivers and software.”
• Forget the network and rejoin. Go to Settings > Network & internet > Wi-Fi > Manage known networks and choose Forget.
• Network reset, as a last step. In Windows 11: Settings > Network & internet > Advanced network settings > Network reset. Microsoft says this removes and reinstalls your network adapters and returns their settings to defaults, so you may need to rejoin Wi-Fi and reinstall VPN software afterward.

iPhone and iPad

Apple’s current troubleshooting page suggests making sure Airplane Mode is off, removing VPN or security apps to test, restarting the router and modem, and trying the 5 GHz band if your router has one. Reset Network Settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings) is the last resort; Apple says to use it “only if other solutions fail.”

Check Connectivity Assist too. Apple says it “uses cellular data to improve your connection when Wi-Fi is slow or unusable.” If your phone seems to leave Wi-Fi on its own, this may be why. Turn it off in Settings > Wi-Fi to test.

Android phones

Pixel phones have Auto-switch to mobile network under Settings > Network & internet > Adaptive connectivity. Google’s help page suggests turning it on; switching it off briefly is our suggestion for testing. Samsung Galaxy phones have Switch to mobile data under Settings > Connections > Wi-Fi > More options > Intelligent Wi-Fi; Samsung says that with it on, “your device will switch to mobile data whenever the Wi-Fi connection is unstable.” Turn the setting off temporarily to see whether Wi-Fi is really dropping.

Google also suggests booting a Pixel into safe mode. If Wi-Fi works in safe mode, a downloaded app is likely the cause.

Private Wi-Fi addresses

Many phones use a private, randomized Wi-Fi address instead of their hardware address; Apple devices use a different one on each network. eero says some devices’ randomized addresses “can change over time,” which can make a device appear offline, and suggests turning off Private Wi-Fi Address on iPhone or choosing Use device MAC on Android if a device keeps going offline. Apple doesn’t describe private addresses as a cause of drops, so treat this as a test, not a fix to leave in place.

If every Wi-Fi device keeps dropping

Weak signal

eero says plainly that “a weak signal can cause your device to drop offline or fail to connect.” Netgear lists weak signal first among its causes of disconnects. If drops happen mainly in far rooms, move the router to a central, open spot, or add a mesh point.

ASUS also suggests keeping the router away from microwave ovens, refrigerators, cordless phones and power boxes. Apple lists microwave ovens, cordless phones, power cables and fluorescent lights as common sources of interference, and notes that Bluetooth and Wi-Fi share the 2.4 GHz band.

Band steering and network names

Many routers now put 2.4 GHz and 5 GHz under one network name and steer devices between them. ASUS says a phone’s own band-preference settings can make its Smart Connect feature ineffective “or lead to frequent disconnections.” TP-Link lists Smart Connect “compatibility problems with certain client devices” as a cause of instability.

If one device keeps dropping or bouncing between bands, try turning band steering off so each band has its own name. Netgear’s disconnect guide takes the opposite view, listing separate band names as a possible cause, so treat this as a test and switch back if it doesn’t help. Our band steering guide shows where the setting is on major brands.

Netgear also lists using a “common or default WiFi network name” as a cause, and eero says conflicts can occur when your network shares a name with another nearby network. Give your network a unique name.

DFS channels on 5 GHz

Some 5 GHz channels are shared with radar, and routers using them must follow the FCC’s Dynamic Frequency Selection (DFS) rules. Under 47 CFR 15.407, a router must listen for radar for 60 seconds before using one of these channels. If it detects radar, it must stop transmitting on that channel within 10 seconds, and the channel is then off-limits for at least 30 minutes.

In practice, TP-Link says connected devices “will encounter disconnection” when the router moves to another channel, though the connection can be restored after a while. ASUS says radar detection “will cause connected WiFi clients to be disconnected from the network for a period of time,” and that 2.4 GHz keeps working meanwhile.

If your 5 GHz devices all drop at once for a short time, now and then, check whether your router is on a DFS channel. On ASUS routers, ASUS says to untick Auto select channel including DFS channels under Wireless > General, along with the 160 MHz option. Other brands use different menus. Our guide to changing your Wi-Fi channel covers the trade-offs. ASUS’s steps also turn off 160 MHz channels, so avoiding DFS can mean giving up the widest channel option.

Firmware, heat and scheduled reboots

• Firmware. TP-Link says “outdated firmware can cause wireless instability,” and ASUS asks users to make sure firmware is up to date. Apple recommends turning on automatic firmware updates.
• Heat. TP-Link says “overheating is a common trigger for automatic reboots.” Xfinity advises keeping its gateways off carpet and out of enclosed cabinets where the vents are blocked.
• Schedules. TP-Link says to check whether an Auto Reboot schedule is turned on. Many Netgear Nighthawk routers have a wireless schedule that can turn Wi-Fi off at set times, and eero can pause devices or limit new devices that haven’t been assigned to a profile. If drops happen at the same time each day, check for these.

Security mode mismatches

Apple recommends WPA3 Personal, or WPA2/WPA3 Transitional “for compatibility with older devices.” Google takes a more cautious line for its Nest Wifi routers: “Some legacy WPA2 devices may be incompatible with WPA3 and experience connection issues when WPA3 transition mode is on.” ASUS also says some older devices can’t use WPA3.

So if an older device keeps dropping after you turned on WPA3 or mixed mode, switching that network to WPA2 is a reasonable test. Our WPA2 vs. WPA3 guide explains the security trade-off.

If the internet itself keeps dropping

If a computer wired to the router loses internet at the same time as everything else, the problem is upstream. Check your provider first. Xfinity, for example, shows outages in its app, on its outage map, and by text if you send “OUT” to 266278.

Then restart in order. Netgear’s steps: power off the modem and router, remove any backup battery, wait two minutes, turn the modem on and give it about five minutes to connect, then turn the router on. Microsoft gives a shorter wait of at least 30 seconds. If the modem’s lights still look wrong after a restart, contact your provider.

If drops keep coming back, see our guide to fixing slow Wi-Fi for testing your connection.

Sources and verification

Bottom line

Find out what’s dropping before changing settings. One device points to that device’s power and Wi-Fi settings. Every Wi-Fi device points to the router: signal, band steering, DFS channels, firmware and heat. Everything including wired points to your provider. Fix one thing at a time so you know which change worked.

Short answer: Your router keeps a list of every device on your network. Open it in the router's app or admin page, match each entry to a device you own, and block anything you can't identify. Unfamiliar entries are often your own phones and laptops using private Wi-Fi addresses, so check those first. If a stranger really is on your network, block them and change your Wi-Fi password.

Your router keeps a list of every device on your network. Open it in the router’s app or admin page, match each entry to something you own, and block anything you can’t identify. If a stranger really is connected, block them and change your Wi-Fi password.

This guide is based on eero, Google, Netgear, ASUS and Apple support documentation. It is not a hands-on test.

Step 1: Open your router’s device list

Google’s list includes devices that “used the network within the last 30 days, including ones not currently connected,” so an entry there doesn’t mean the device is online now. Netgear notes a device’s IP address can change when it rejoins, while its MAC address “does not change.” Eero says devices that haven’t connected in seven days drop off its list automatically.

Step 2: Identify unfamiliar devices

Most unknown entries turn out to be your own devices. Work through them:

• Smart home gear. Plugs, bulbs, TVs, speakers and printers often show a manufacturer name or a string of letters and numbers. ASUS’s client details include the manufacturer, which helps.
• Phones and laptops with private addresses. Apple says its devices identify themselves “to each network using a different Wi-Fi address” and may rotate it. On networks secured with WPA2 or stronger, Apple devices use a fixed private address by default; on weak or open networks, it rotates every two weeks. So the MAC address in your router’s list may not match the one printed on the device. On an iPhone, open Settings, Wi-Fi, then tap the More Info button next to your network to see the address it uses.
• Turn things off one at a time. If you still can’t place an entry, switch off or disconnect devices one by one and watch which entry goes offline.
• Rename what you’ve identified in the router’s app, so the next check is quicker.

Step 3: Block what you don’t recognize

• eero: find the device under Devices, open it, tap the more options icon in the top-right corner, then tap Block device. Eero says blocking “disconnects the device and prevents it from rejoining your network, even if the correct password is entered.” Blocking isn’t available when eero is in bridge mode.
• ASUS: in the web interface, click the device under Network Map, Clients, turn on Block Internet Access and click Apply. In the app, open the device and tap Block. ASUS says a blocked device “cannot connect to the Internet.”
• Netgear: the Attached Devices list shows whether each device is Allowed or Blocked. Look for access control settings on your model to block a device.
• Google Nest Wifi and Google Wifi: Google’s device-list help page doesn’t cover blocking. If you can’t block an unknown device, change your Wi-Fi password instead.

Step 4: Change your Wi-Fi password if someone got in

Blocking stops one device. If someone outside your household had the password, they can connect again from another device, so change it. Every device in your home will need the new password afterward.

While you’re in the settings:

• Use WPA3, or WPA2/WPA3 mixed mode, if your router offers it. See WPA2 vs. WPA3.
• Turn off WPS, which lets devices join without the password. See should you turn off WPS and UPnP.
• Give visitors a guest network instead of your main password. See guest networks for smart home devices.
• Change the router’s admin password too, and work through our router hardening checklist.

If your router no longer gets security updates, see is my router still getting security updates.

Fact-check notes

Bottom line

Check your router’s device list every so often and name what you recognize. Most unknown entries are your own gear, especially Apple devices using private addresses. If something truly isn’t yours, block it and change your Wi-Fi password.

Short answer: Leave channel selection on Auto unless you have dropouts or slowdowns that point to interference, such as problems that come and go at busy times. If you set a channel by hand on 2.4 GHz, use 1, 6 or 11, the three that don't overlap in the US. Changing the channel won't fix a room that is simply too far from the router.

Leave your router’s channel on Auto unless you have problems that point to interference: dropouts or slowdowns that come and go, often at busy times of day, in rooms that otherwise get a decent signal. If you do pick a channel by hand on 2.4 GHz, use 1, 6 or 11. Changing the channel won’t fix a room that is too far from the router.

This guide is based on Apple, Netgear, ASUS, eero and Cisco Meraki documentation. We have not tested channel changes on these routers.

What is a Wi-Fi channel?

Apple describes channels as “lanes in a street”: each band is split into separate channels, and your router uses one at a time on each band. Nearby routers on the same or overlapping channels compete for airtime, which can slow things down.

When channel selection is set to automatic, Apple says, “your router selects the best Wi-Fi channel for you.” Netgear says its routers pick a 2.4 GHz channel based on your environment, and ASUS routers set the channel to Auto by default.

When does changing the channel help?

Netgear suggests changing channels if you have “frequent lost connections, slow data transfers, or other WiFi issues that can be caused by interference,” and advises keeping the defaults otherwise. Apple’s interference guide lists changing the channel, or letting the router scan for the least congested one, as a fix for interference.

Which channel should you pick?

2.4 GHz: use 1, 6 or 11. Cisco Meraki’s channel planning guide says that in the US, channels 1 through 11 are permitted, which “provides three non-overlapping channels 1, 6 and 11.” Other channels overlap their neighbors. Apple also recommends a 20 MHz channel width on 2.4 GHz to avoid problems near other networks and Bluetooth devices.

5 GHz and 6 GHz: Auto usually works. These bands have many more channels. Apple recommends Auto or all widths for them, and says interference “is less of a concern in these bands.” See 2.4 GHz vs. 5 GHz vs. 6 GHz.

If you have more than one router or access point, Apple recommends configuring each to use a different channel, especially when they’re close together. Netgear, by contrast, says extenders should use the same channels as the router, so check your extender’s instructions.

What are DFS channels on 5 GHz?

Part of the 5 GHz band is shared with radar. Meraki says these channels “are required to use Dynamic Frequency Selection (DFS),” and that an access point that detects radar “must immediately stop using that channel and randomly pick a new channel.”

ASUS describes what that means at home:

• Before using a DFS channel, the router runs a Channel Availability Check that takes “1-10 minutes depending on the country,” and 5 GHz is unavailable during it.
• If radar is detected, devices may disconnect for a while and reconnect on the new channel.
• A router set to 160 MHz may drop to 80 MHz.
• ASUS suggests not enabling DFS channels where 5 GHz disconnects or runs slowly because of heavy interference.

If your 5 GHz network drops for a minute or more at random, try excluding DFS channels from automatic selection.

How to change the channel

Netgear: sign in at routerlogin.net, open Wireless, scroll to the band you want, pick a channel from the Channel menu, and click Apply. Not every channel is available in every region. Netgear also suggests the WiFi Analytics tool in its Nighthawk and Orbi Android apps to find less congested channels.

ASUS: sign in to the web interface at your router’s address or asusrouter.com, go to Wireless, then General, choose the band and set the Control Channel. On 5 GHz, uncheck “Auto select channel including DFS channels” before choosing a specific channel. ASUS says channel selection is in the web interface only, not the app.

eero: there’s no manual channel setting. Eero says it “selects optimal channels for your network” over two days to a week, and changes them infrequently because “channel changes can briefly disrupt your connection.” It also notes that reboots and resets restart this process, so avoid unnecessary restarts.

Google Nest Wifi and Google Wifi: Google’s help pages describe the system choosing bands automatically and don’t describe a manual channel setting.

After any change, test in the rooms that had problems for a day or two before deciding it worked.

Fact-check notes

Bottom line

Keep channels on Auto. If problems come and go and look like interference, try 1, 6 or 11 on 2.4 GHz, move devices to 5 GHz, or exclude DFS channels if 5 GHz drops at random. If a room is weak all the time, fix coverage instead.

Short answer: Walk the house with your phone and run a speed test in each room to find where Wi-Fi drops off. Most dead zones come from distance, dense walls or metal, or a router hidden in a cabinet or basement. Move the router to a central, raised, open spot first. If a room is still weak, add a wired connection or a mesh point placed halfway to the dead zone, not inside it.

To fix a Wi-Fi dead zone, first find out where the signal actually falls off. Walk the house with a phone and run a speed test in each room. Then work through the fixes from cheapest to most expensive: move the router, clear obstacles, change the channel, and only then add a wired link or a mesh point.

This is a research-based guide built from Apple, eero, Google and ASUS documentation. We have not mapped coverage in a test home.

Step 1: Map your weak spots

You don’t need special tools.

1. Pick one device, ideally the phone or laptop you use most.
2. Run a speed test in each room, standing where you’d normally use the device. Note the download speed and the signal bars.
3. Repeat at a busy time, such as the evening, to catch interference from neighbors’ networks.
4. Check the router’s app. Mesh apps often show connection quality per device or per unit. Google suggests running a mesh test after moving a point.

If your router or app shows signal strength in dBm, ASUS gives these bands: -20 to -70 dBm is good, -71 to -80 dBm is fair, and -81 dBm or lower is weak.

A room that is slow on every device is a coverage problem. If one device is slow everywhere, the device is the problem. Our slow Wi-Fi guide covers that test, and our guide to slow Wi-Fi on a fast connection explains the difference between Wi-Fi and plan speed.

Step 2: Move the router

Placement is the free fix. The guidance from eero and Google lines up:

• Central. Eero suggests moving the modem and main unit “out of your basement and into a more centralized location.”
• Raised. Eero recommends a height halfway between floor and ceiling. Google suggests a shelf or TV stand, ideally at eye level.
• In the open. Eero says not to put units inside a media console or cabinet. Google says to avoid objects that physically block the signal.
• Away from heat. Eero says direct sunlight and incandescent bulbs can hurt performance.

If your provider’s cable or fiber outlet is in a corner, a longer Ethernet cable between the modem and the router can let you move the router without moving the outlet.

Step 3: Check what’s in the way

Some materials block Wi-Fi far more than others. Apple’s interference guide rates them:

Eero adds that older homes with plaster, lath or chicken wire in the walls are “particularly hard” for Wi-Fi, and that placing units near doors can help because wood is easier for the signal to pass through. Mirrors, aquariums, refrigerators and metal furniture are also on eero’s list of things to keep units away from.

Step 4: Reduce interference

Interference can turn a weak area into a dead one. Apple lists microwave ovens, cordless phones, fluorescent lights, wireless video cameras and power cables as common sources. Its suggestions:

• Change the Wi-Fi channel, or let the router scan for the least congested one. Our Wi-Fi channel guide has the steps.
• Move devices to 5 GHz where the router supports it, which takes them off the busier 2.4 GHz band.
• Reduce the number of active devices on the same band.

5 GHz and 6 GHz are faster but reach less far through walls than 2.4 GHz. See 2.4 GHz vs. 5 GHz vs. 6 GHz for the trade-off.

Step 5: Add coverage, wired first

If a room is still weak after moving the router, you need a second access point. Wired links are more reliable than wireless ones, so check these first:

For wireless units, placement matters as much as the hardware:

• Halfway, not in the dead zone. Eero says: “Don’t place eeros directly in dead zones. Instead, place them halfway between your gateway eero and dead zones.”
• Spacing. Eero suggests 20 to 30 feet apart, and no more than 50 feet. Google says no more than two rooms from the router or another point.
• Line of sight between units helps, according to both eero and Google.

Homes with thick walls may need more units, eero says. Or connect them by cable; see wired vs. wireless mesh backhaul.

Fact-check notes

Bottom line

Find the dead zones before buying anything. Most homes get the biggest improvement from moving the router somewhere central, raised and open. If a room is still weak, connect a second access point by cable, MoCA or powerline, or place a mesh point halfway between the router and the weak room.

Short answer: Band steering, often called Smart Connect, combines your router's 2.4 GHz, 5 GHz and 6 GHz bands under one network name and moves dual-band devices to the band it judges best. Most homes should leave it on: Apple recommends one name for all bands. Turn it off only for a specific problem, such as a 2.4 GHz-only device that won't set up, and turn it back on afterward.

Band steering puts your router’s 2.4 GHz, 5 GHz and, on newer routers, 6 GHz bands under one network name, then nudges each device that supports more than one band toward the band the router judges best. Leave it on unless you have a specific problem. The usual reason to turn it off is a smart plug or camera that only supports 2.4 GHz and fails during setup. Turn it back on afterward.

This is an explainer based on router makers’ and Apple’s support documentation. It is not a hands-on test.

What band steering does

Without band steering, a dual-band router broadcasts two networks, such as “Home” and “Home-5G,” and you pick one on each device. With it, you see a single name.

The router then helps decide which band each device uses:

• Netgear says Smart Connect “automatically chooses the best WiFi band for your device.”
• TP-Link says Smart Connect assigns each device to the band “that provides the fastest speed” and balances load across bands. Devices that only support 2.4 GHz stay on 2.4 GHz.
• Google says Nest Wifi and Google Wifi steer devices to “the band with the best performance for each device,” and that devices pick a band based on compatibility, security, signal strength and distance from a Wi-Fi point.
• ASUS lets you adjust the rules on many models: when steering is triggered, which band a device is sent to, and a “bounce detect” limit that keeps a device on one band for a while if it has been moved too often.

The device still has the last word on which band it joins. Routers influence that choice. The Wi-Fi Alliance’s Agile Multiband program exists to support this kind of information exchange between access points and devices, so that band and channel decisions can be made with better information.

What each brand calls it

Netgear says Smart Connect “might or might not be disabled by default,” depending on the model. Check your router if you’re not sure which mode you’re in.

Why most homes should leave it on

• Apple recommends one name. Its router guidance says to use a single network name for all bands and warns that with different names, “devices might not connect reliably.” On Wi-Fi 6E networks, Apple devices flag the network as having limited compatibility if the names differ.
• It helps on mesh systems. Eero says its single network name lets devices “seamlessly roam” across its mesh.
• It moves capable devices off 2.4 GHz. Microsoft’s Teams network guidance recommends band steering to move dual-band devices to 5 GHz, which it says is better suited to real-time media. See 2.4 GHz vs. 5 GHz vs. 6 GHz for the trade-offs between bands.

When turning it off can help

• A 2.4 GHz-only device won’t set up. TP-Link suggests separating the bands when smart home devices that support only 2.4 GHz struggle to connect. On eero, hide the 5 and 6 GHz bands for 30 minutes instead. Our 2.4 GHz smart device guide has the steps for each brand.
• A device keeps dropping or switching bands. ASUS says a phone’s own Wi-Fi band-preference settings may make Smart Connect ineffective “or lead to frequent disconnections.” Check the device’s settings first.
• An old device can’t connect at all. On ASUS routers, setting the steering rule to allow only 802.11ac (Wi-Fi 5) devices means 802.11n-only devices “will not be able to connect.” Restoring the default rules fixes this.

Before turning band steering off for good, try the simpler fixes. ASUS recommends its default steering settings “if there are no special requirements.” Update the router’s firmware, and check whether the device simply has a weak signal. Our slow Wi-Fi guide covers how to tell.

How to turn it off, and what changes

• Netgear: sign in at routerlogin.net, open Wireless, uncheck Enable Smart Connect, then click Apply.
• ASUS: on newer firmware, give each band its own network name and password. On older firmware, turn off Enable Smart Connect under Wireless, then General.
• TP-Link: in tplinkwifi.net, go to Advanced, then Wireless, and switch off Smart Connect. In the Tether app, go to More, Wi-Fi Settings, then 2.4GHz & 5GHz Network.

Once the bands have separate names, each device stays on the band you choose. That means you manage it: a laptop on the 2.4 GHz name stays there even when 5 GHz would be faster. If you split the bands only for a setup, switch Smart Connect back on afterward.

Band steering is the right default for most homes. Leave it on, keep your router’s firmware current, and switch it off only long enough to fix a specific device problem, such as a 2.4 GHz-only smart plug that won’t set up.

Short answer: Zoom and Teams need only a few megabits per second, so freezes and robotic audio usually come from an unsteady connection, not a slow plan. Use Ethernet or a strong 5 GHz signal, leave WMM on, turn on your router's video-call priority feature if it has one, and stop large uploads from swamping the line during calls.

Video calls need far less speed than most home plans provide. When Zoom or Teams freezes, the cause is usually an unsteady connection: weak Wi-Fi, a crowded band, or another upload filling the line. Fix those first. Then use your router’s video-call priority setting if it has one.

This is a research-based guide built from Zoom’s and Microsoft’s published requirements and router makers’ support documentation. We have not measured call quality on these routers ourselves.

Quick answer: the settings that help most

1. Plug in with Ethernet if you can. If you can’t, connect on 5 GHz or 6 GHz, close to the router or a mesh point.
2. Leave WMM on. Apple recommends it, and Microsoft recommends QoS or WMM for Teams.
3. Turn on your router’s video-call mode, if it has one. ASUS, Google and eero all offer one (see the table below).
4. Keep big uploads off the line during calls. Cloud backups and large file syncs compete with your outgoing video.
5. Fix bufferbloat if calls break up whenever someone else is downloading. See our bufferbloat guide.

How much bandwidth do video calls use?

Zoom says it adjusts bandwidth to each participant’s network. Google’s Meet requirements page lists hardware and says you need a broadband connection, but gives no bandwidth figures.

The figures are per person on a call. Two people on separate 1080p Zoom calls need roughly double. Upload is the tighter limit on many cable plans, so check yours with our guide to how much internet speed you need.

Why calls freeze on a fast plan

Bandwidth alone does not guarantee a good call. Microsoft says “provisioned bandwidth alone” doesn’t guarantee quality, and that calls with static, cut-outs or voices that “sound like robots” could point to jitter or packet loss. When bandwidth does run short, Microsoft says Teams prioritizes audio over video.

The common home causes:

• Weak or crowded Wi-Fi. Microsoft says the 2.4 GHz band is often congested by consumer devices, and that 5 GHz is better suited to real-time media. See 2.4 GHz vs. 5 GHz vs. 6 GHz.
• A full upload. A backup or game download on another device can push your call’s traffic into a queue. That delay is bufferbloat.
• The Wi-Fi link, not the plan. If a wired test is fast but your laptop is slow, the problem is local. Our guide to slow Wi-Fi on a fast connection walks through the checks.

Router settings for video calls, by brand

On an ASUS router, open the router’s web interface, go to Adaptive QoE, switch on QoS, pick Work from Home and apply. ASUS also offers a Bandwidth Limiter that caps a chosen device. It says any limit should be lower than your provider’s maximum speed, or it won’t take effect.

On Google Nest Wifi or Google Wifi, open the Google Home app, then Wi-Fi, Network settings and Preferred activities. To prioritize a single laptop instead, open Wi-Fi, then Devices, choose the laptop and pick a duration.

On eero, open the Discover tab in the eero app, tap eero Labs and turn on Optimize for Conferencing and Gaming.

If your router has none of these, check its QoS or traffic-priority settings, and make sure WMM is enabled. Apple says disabling WMM “can affect the performance and reliability of devices on the network.”

Other settings worth checking

• One network name across bands. Apple recommends a single name for all bands. If you split bands, make sure the work laptop joins 5 GHz or 6 GHz.
• 2.4 GHz channel width. Apple recommends 20 MHz on 2.4 GHz and Auto on 5 GHz and 6 GHz.
• Work VPN. Microsoft says routing Teams traffic through a VPN can add “extra latency and jitter.” That setting belongs to your employer, so ask its IT team whether calls bypass the VPN.

When to change hardware instead

If the room you work in has a weak signal, settings won’t fix it. Run a cable, use MoCA over existing coax, or add a mesh point with a wired backhaul. If your provider’s gateway lacks priority settings, our guide to buying your own router covers what to check before you switch.

Fact-check notes

Bottom line

A video call needs about 4 Mbps in each direction at most, so a faster plan rarely fixes a bad call. Get the work device onto Ethernet or a strong 5 GHz or 6 GHz signal, leave WMM on, switch on your router’s video-call priority, and stop other uploads from crowding the line.

Short answer: Look up your exact model and hardware version on the maker's end-of-life list, then check the router's app or admin page for a recent firmware update. If the model has reached end of life, it will not get security fixes again. The FBI and NSA both advise replacing routers in that state, because attackers target known, unpatched flaws.

Find your router’s exact model and hardware version on its label, then look it up on the manufacturer’s end-of-life list. If it is listed, it will not get security fixes again, and the FBI and NSA both advise replacing it. If it isn’t listed, open the router’s app or admin page, install any pending firmware update, and turn on automatic updates.

This is an explainer based on manufacturers’ published support policies and US government guidance. Policies differ by brand and region, so check your own model rather than relying on a general rule.

Why do security updates matter for a router?

Your router sits between every device in your home and the internet. When researchers or attackers find a flaw in its software, the fix arrives as a firmware update. A router that no longer gets updates keeps every flaw found after that date.

The FBI described this in a public service announcement on May 7, 2025. It said that when a router reaches end of life, the manufacturer is “not actively supporting the hardware,” so there are no more software updates or security patches. It warned that criminals were exploiting such routers with a malware family called TheMoon, which it said “allows cyber actors to install proxies on unsuspecting victim routers,” routing other people’s criminal traffic through them. The FBI advised replacing end-of-life routers and turning off remote administration.

The NSA’s home network guidance, published in February 2023, says routers “should be updated to the latest patches, preferably through automatic updates,” and “should also be replaced when they reach end-of-life (EOL) for support.”

How long do manufacturers support routers?

Two details make a difference:

• The clock usually starts when the model stops being sold, not when you bought it. Netgear’s three years runs from the last sale date, which can vary by country or region. A router bought near the end of its sales life may have little support left.
• Eero’s dates are published per model. Its table runs from March 11, 2030 for the eero Pro and eero Beacon to October 31, 2031 for most newer models, including the eero 6, eero 7 and eero Max 7 lines. Eero says that after updates end, “your eero device will still work and can still provide wifi,” but without guaranteed security fixes.

How do I check my router?

1. Find the model and hardware version. It’s on the label on the bottom or back. Netgear says that if no version is shown, the product is version 1. ASUS also points to the label and the box.
2. Search the maker’s list.
   • Netgear: search the End of Service Products page by model number. Netgear also offers end-of-service alerts if you register your product.
   • ASUS: check the End-of-life product list. ASUS notes that end-of-life status can vary by region.
   • TP-Link: check the TP-Link End of Life Products list, and note that dates vary by region.
   • eero: find your model’s date on the eero Software Security Updates page.
3. Check the firmware date. In the router’s app or admin page, look for the firmware version and an update option. Install anything pending.
4. Turn on automatic updates if your router offers them. Apple’s router guidance recommends setting routers to install firmware updates automatically. Eero installs updates automatically and lets you choose a preferred time under Settings, Software updates, Preferred update time.

For provider-supplied gateways, ask the provider. They typically manage firmware for their own equipment.

What if my router is no longer supported?

Plan to replace it. In the meantime, reduce the risk:

• Turn off remote administration. The FBI says to “disable remote management/remote administration, save the change, and reboot the router.”
• Change the admin password to a strong, unique one. The FBI recommends passwords of 16 to 64 characters.
• Turn off features you don’t use, such as WPS and UPnP. See should you turn off WPS and UPnP.
• Move smart home devices to a separate network if the router supports one. See guest networks for smart home devices.

When you buy a replacement, check how long the maker supports its routers before you choose. Our router hardening checklist covers the settings to change on day one, and our guides to Wi-Fi 6 vs. Wi-Fi 6E and router vs. mesh help with the choice. Under the FCC’s 2026 router rule, previously authorized models can still be bought; see our news report on TP-Link and the FCC for the current state of that rule.

Fact-check notes

Bottom line

Check your router’s model on its maker’s end-of-life list today, and turn on automatic updates. If it’s no longer supported, switch off remote administration and plan a replacement. When you buy the next one, add the maker’s update policy to the spec sheet you compare.

Short answer: If you plug your own router or mesh system into your internet provider's gateway, both devices may route traffic, which is called double NAT. It often works fine for browsing, but can cause console NAT warnings and confusing settings. The usual fix is to put the provider's gateway in bridge mode so only your router routes. If the gateway can't be bridged, put your own router in access point mode instead.

When you plug your own router or mesh system into the gateway your internet provider supplied, you can end up with two routers doing the same job, which is called double NAT. It often goes unnoticed, but it can trigger game console warnings and make some features misbehave. The fix is to let only one device route: put the provider’s gateway in bridge mode, or, if it can’t be bridged, put your own router in access point mode.

This is a how-to based on Xfinity, eero, Netgear and TP-Link support documentation. We have not tested these setups ourselves, and menu names vary between models.

What is double NAT?

NAT stands for Network Address Translation. Your internet provider gives your home one public address. Your router hands each device a private address, and NAT translates between the two so all your devices can share the connection. Eero describes it as a way for several devices to share one public IP address.

A provider gateway is a single box that combines a modem and a router. If you connect your own router behind it, and both keep routing, traffic is translated twice: that is double NAT. Eero describes it as two routers performing NAT, which creates two separate networks.

Does double NAT cause problems?

Sometimes. Web browsing, streaming and video calls usually work, because those connections start from your device. Problems show up with things that need devices to reach each other or accept connections from outside:

• Game consoles. Xbox support lists “Double NAT detected” as one of the errors that can stop party chat and multiplayer from working.
• Two networks with the same name. Eero warns that running two networks with the same Wi-Fi name at once “will lead to technical complications.” Devices can join the gateway’s Wi-Fi and lose sight of devices on yours.
• General reliability. TP-Link says double NAT can cause “connectivity and performance issues.”
• Port forwarding. With two routers, a port has to be opened on both, which is easy to get wrong.

Eero also points out that double NAT has one upside: it lets you set up a new system quickly without changing the provider’s equipment. Some setups start that way and fix it afterward.

How do I check whether I have double NAT?

Open your own router’s app or admin page and find its internet (WAN) address. If it begins with 192.168., 10. or anything from 172.16. to 172.31., your router is getting a private address from the device in front of it, which usually means double NAT. Those three ranges are reserved for private networks by RFC 1918, the internet standard that defines them. Treat this as a strong hint rather than proof: some providers run their own network-level NAT, which can also leave your router without a public address.

On an Xbox, Xbox support says the NAT type and any “Double NAT detected” message appear under Profile & system, Settings, General, Network settings.

How do I fix it: bridge mode or access point mode?

Pick one device to do the routing.

The router makers’ own guidance leans toward bridging the gateway:

• Eero recommends putting the modem-router combo in bridge mode for the best performance and access to all eero features.
• TP-Link recommends bridge mode on a combined modem-router to avoid double NAT when adding Deco.
• Netgear prefers bridge mode on the provider gateway. If that isn’t possible, it says “you must turn its WiFi off and put your Orbi or Nighthawk router in AP mode,” and notes that “some router features are disabled in AP mode.”

How do I put an Xfinity gateway in bridge mode?

Xfinity documents these steps for its gateways:

1. On a device connected to your home network, go to the Admin Tool at http://10.0.0.1. You may need to allow Admin Tool access in the Xfinity app first.
2. Sign in with the username admin and the password on the sticker on the gateway, unless you changed it.
3. Go to Gateway, then At a Glance.
4. Next to Bridge Mode, click Enable, then OK at the warning. The gateway may restart.
5. Connect your own router to any Ethernet port on the gateway.

Things Xfinity says to know first:

• Only one device can be connected to the gateway while it is in bridge mode.
• You can still use the Xfinity app to manage your account, but not to manage and personalize your network or use WiFi Extenders.
• Xfinity CyberSecure isn’t available in bridge mode, and you can’t enable bridge mode if you have already activated WiFi Extenders.
• Bridge mode doesn’t turn off the Xfinity WiFi Home Hotspot feature on gateways that have it.
• To turn bridge mode off later, the device you use must be connected to the gateway by Ethernet.

Other providers’ gateways may work differently. Check your provider’s help pages.

When would I bridge my own router instead?

Usually, you wouldn’t; it’s the provider’s gateway you bridge. But eero lists cases where its own system may need to be bridged and the provider’s equipment kept as the router: if your provider is AT&T U-verse and its equipment provides Wi-Fi and addressing, if your provider requires PPPoE (a login-based connection type), or if your provider requires a specific MAC address that matches its own equipment. Eero notes that eero Pro 6 and eero 6 now support PPPoE.

Eero says that in bridge mode you “won’t be able to manage your network’s advanced features through the eero App,” and that eero Plus features including Advanced Security, Ad Blocking and Content Filters don’t work properly. To set it, eero’s path is Settings, Advanced networking, DHCP & NAT, then switch from Automatic to Bridge.

A setup checklist

1. Decide which device routes. Usually your own router, with the gateway bridged.
2. Bridge the gateway or, if it can’t be bridged, set your router to AP mode. Not both.
3. If you can’t bridge, turn off the gateway’s Wi-Fi. TP-Link advises against giving the gateway and your system the same network name.
4. Wire correctly. TP-Link says not to connect more than one Deco directly to the existing router in Router mode, because it can create a network loop.
5. Check the result. Your router’s WAN address should now be a public address, not one starting with 192.168., 10. or 172.16 to 31. Run the network test on any game console.

If you are still deciding whether to keep renting the gateway at all, see buying your own router vs. using your provider’s. For console NAT types, see our WPS and UPnP guide and gaming router guide. For choosing the system you’ll plug in, see router vs. mesh.

Fact-check notes

Bottom line

Two routers in a row works, but it isn’t tidy. Bridge the provider’s gateway so your own router does the routing, and accept that the gateway’s extra features go away. If the gateway can’t be bridged, turn off its Wi-Fi and put your router in AP mode. Then check your router’s WAN address and your console’s NAT type to confirm the fix.

Short answer: Change your router's DNS if you want features your provider's DNS doesn't offer, mainly blocking known malicious sites or a published privacy policy you prefer. Don't expect faster downloads; DNS only affects the lookup before a connection starts. Set it once on the router and every device on the network uses it.

Change your router’s DNS if you want something your internet provider’s DNS doesn’t give you: blocking of known malicious websites, filtering for a family network, or a privacy policy you prefer. Don’t change it expecting faster downloads. DNS handles the lookup before a connection starts, not the connection itself.

This is a how-to based on the DNS providers’ and router makers’ own documentation. We have not measured DNS speeds for this guide.

What does DNS do?

DNS stands for Domain Name System. When you type a website name, your device asks a DNS server for the site’s numeric IP address, then connects to that address. It works like a phone book lookup before the call.

By default your router uses DNS servers assigned by your internet provider, and passes them on to every device that joins your network. Netgear’s support notes that “most ISPs supply DNS addresses automatically.” Changing the DNS setting on the router changes it for every device that gets its settings from the router, including smart TVs and other devices with no DNS option of their own.

Will changing DNS make my internet faster?

Not your download speed. Once the lookup finishes, the connection runs at the speed your plan and Wi-Fi allow, whichever DNS server answered.

Lookups can still add delay to page loading. Google’s Public DNS documentation says “DNS lookups significantly impact website loading speed,” especially on pages that pull content from many domains, and gives an example in which five lookups made up several seconds of an 11-second page load. That example is Google’s own illustration, not a measurement of any particular DNS provider. Whether a different server is quicker than your provider’s depends on where you are and which servers are closer, so if speed is your reason, test before and after rather than assuming.

For streaming, gaming and downloads, see how much internet speed you need and why Wi-Fi can be slow when your internet is fast.

Which public DNS should I choose?

Three widely used free services, with their own published details:

All three also publish IPv6 addresses. For Cloudflare’s standard service they are 2606:4700:4700::1111 and 2606:4700:4700::1001; for Google, 2001:4860:4860::8888 and 2001:4860:4860::8844.

How to choose:

• For protection from known malicious sites, use a filtering option: Quad9’s 9.9.9.9 or Cloudflare’s 1.1.1.2. Quad9 also offers 9.9.9.10 without malware blocking, which it labels “for experts only!”
• For a family network, Cloudflare’s 1.1.1.3 adds adult-content blocking.
• For no filtering at all, use Cloudflare’s 1.1.1.1 or Google’s 8.8.8.8.
• For privacy, read each provider’s policy in full. The summaries above are their own statements, and we have not audited them.

DNS filtering is one layer, not a security system. It only blocks domains already on the provider’s lists, and devices set to use their own DNS bypass the router’s setting. Pair it with the basics in our router hardening checklist.

How do I change DNS on my router?

Before you start, write down the DNS addresses your router uses now. Google recommends recording your current settings so you can switch back. Enter two addresses, a primary and a secondary from the same service, and don’t use the same address in both fields.

eero

1. Open the eero app and tap Settings.
2. Tap Advanced networking, then DNS.
3. Turn on Custom DNS and enter the IPv4 and, if you want, IPv6 addresses.
4. Tap Save. Eero says the network reboots to push the change to devices.

If DNS settings are grayed out, eero says to turn off eero Plus filters, Advanced Security and Ad Blocking first, under Home, Security & privacy, Network Controls.

Netgear

1. Browse to routerlogin.net and sign in.
2. Go to BASIC, then Internet.
3. Under Domain Name Server (DNS) Address, select Use These DNS Servers.
4. Enter the Primary DNS and Secondary DNS, then click Apply.

Other routers and provider gateways

Google notes that “every router uses a different user interface for configuring DNS server settings.” Look in the router’s app or admin page for DNS under Internet, WAN or advanced network settings.

Some provider gateways won’t let you change DNS. Google warns that “some ISPs hard-code their DNS servers into the equipment they provide.” If that’s your situation, set DNS on your own router placed behind the gateway, or on individual devices. Our guide to buying your own router vs. using your provider’s covers that setup.

How do I check it worked?

After the change, restart a device or reconnect it to Wi-Fi so it picks up the new settings, then:

• Visit a few sites to confirm they load. If nothing loads, recheck the addresses for typos.
• Check the device’s network details for the DNS servers it received. Some routers hand out their own address and forward lookups to your chosen servers; eero does this with some features turned on, so you may see the router’s address instead.
• If you chose a filtering service, the provider may offer a way to confirm you’re using it. Quad9, for example, links to a tool for searching blocked domains.

If something breaks, enter the addresses you wrote down, or switch the router back to getting DNS automatically.

Fact-check notes

Bottom line

Changing your router’s DNS is quick, reversible and covers every device on the network. Do it for malware or content filtering, or for a privacy policy you prefer, and pick the service by those features. Don’t do it to fix slow speeds; check your plan and Wi-Fi for that. Write down your current settings before you start.

Short answer: Many smart home devices can only use the 2.4 GHz band, and setup can fail when your router combines all bands under one network name. Temporarily hide the 5 GHz band (eero has a button for this), or move your phone farther from the router so it switches to 2.4 GHz, then run setup again. Splitting the bands into separate names permanently works too, but Apple warns it can make other devices connect less reliably.

If a smart plug, camera or bulb won’t finish setup, the likely reason is the Wi-Fi band. Many smart home devices only work on 2.4 GHz, while your phone, which runs the setup app, is probably on 5 GHz. Get the phone onto 2.4 GHz for a few minutes, by pausing the 5 GHz band or moving farther from the router, then run setup again.

This is a how-to guide based on the router makers’ own support documentation. We have not tested these steps on every router, and menu names change between app versions.

Why do smart home devices need 2.4 GHz?

Wi-Fi uses three bands: 2.4 GHz, 5 GHz and, on newer routers, 6 GHz. Many smart home devices have a radio for 2.4 GHz only. Google’s support page says some smart home devices “can only use the 2.4 Ghz band and do not support 5 and 6 Ghz,” and eero says many smart home and IoT devices require 2.4 GHz. (IoT stands for Internet of Things, the umbrella term for connected household devices.)

The 2.4 GHz band also reaches farther. TP-Link’s Kasa support notes that it “typically provides a longer range than the 5 GHz band,” which suits devices placed in garages, porches and far corners. Our Wi-Fi bands guide explains the trade-offs.

Why does setup fail on a modern router?

Most current routers broadcast one network name (SSID) for all bands and decide which band each device uses. This is called band steering. Netgear and TP-Link call their version Smart Connect, and eero and Google work this way by default. Our band steering explainer covers how it works and when to turn it off.

For everyday use that is helpful. Setup is where it can go wrong, because your phone may sit on 5 GHz while the device can only use 2.4 GHz. Google says you “may need to connect your phone to the 2.4 GHz band manually” to set up a 2.4 GHz-only device.

The fix is to get the phone, and so the device, onto 2.4 GHz for the length of the setup.

How do I connect a 2.4 GHz device on my router?

eero

Eero has a built-in option for exactly this:

1. Open the eero app and tap Settings.
2. Scroll down and tap Troubleshooting.
3. Tap My device won’t connect, then My device is 2.4 GHz only.
4. Tap Pause 5 GHz and 6 GHz.
5. Run the device’s setup while the pause is on.

The bands turn back on by themselves. Eero’s two support articles give different durations: one says the pause lasts “for up to 10 minutes,” the other says 30 minutes. Start setup right away to be safe. Eero says devices that connect during the pause stay connected after the bands return, and that there is no way to permanently split eero’s bands into separate names.

Google Nest Wifi and Google Wifi

Google’s system uses one network name, and its help page doesn’t describe a way to switch off 5 GHz. It suggests two approaches:

• Use your phone’s own settings to pick the 2.4 GHz band, if your phone allows it. Check the phone’s manual.
• Otherwise, “move farther away from your router and point until your phone moves to the 2.4 GHz band,” then continue setup. This works because 2.4 GHz reaches farther than 5 GHz.

Netgear

Netgear says Smart Connect “combines your NETGEAR router’s WiFi bands into a single WiFi network name,” and that it “might or might not be disabled by default” depending on the model. Turning it off gives each band its own name, such as NETGEARWIFI for 2.4 GHz and NETGEARWIFI-5G for 5 GHz. To turn it off, sign in at routerlogin.net, open the Wireless page (some models use Settings, Setup, Wireless Setup), clear Enable Smart Connect, and click Apply.

TP-Link

TP-Link says that with Smart Connect on, “both bands share the same network name (SSID) and password,” and suggests turning it off for devices that struggle with that. In the web interface it is under Advanced, Wireless, Wireless Settings. In the Tether app it is under More, Wi-Fi Settings, 2.4GHz & 5GHz.

Should I keep the bands split permanently?

Usually not. The advice differs between manufacturers, and the difference matters:

• TP-Link’s Kasa support recommends using “a different network name (SSID) for the 5 GHz band than for the 2.4 GHz band” when setting up its devices.
• Apple recommends one name for all bands and warns: “If you give your 2.4 GHz, 5 GHz, or 6 GHz bands different names, devices might not connect reliably to your network.”

A temporary fix, like eero’s pause or Google’s move-farther-away approach, avoids the conflict. If your router only offers a permanent split, here is one approach to test. It is our suggestion, not a manufacturer instruction: keep your original network name on the 2.4 GHz band and give 5 GHz a new name. Devices already set up on 2.4 GHz should keep connecting, and you can move phones and laptops to the 5 GHz name.

Be aware that if you later turn Smart Connect back on and the network name changes, devices set up on the old name may need setting up again.

What else can stop a smart device from connecting?

If the band isn’t the problem, check these:

• The password. Re-type it carefully; setup apps rarely show which character is wrong.
• Distance. Do setup near where the device will live, and make sure the signal is reasonable there.
• Security settings. Some older devices don’t support WPA3. Kasa’s support suggests WPA2 with AES. A WPA2/WPA3 mixed mode lets both old and new devices connect; see WPA2 vs. WPA3.
• Channel settings. Kasa’s support suggests a 2.4 GHz channel of 1, 6 or 11 and a 20 MHz channel width. Apple also recommends 20 MHz for 2.4 GHz, saying it “helps to avoid performance and reliability issues.”
• The phone. Kasa’s support suggests trying a different phone, and making the phone forget any saved network profile before reconnecting.

Where should smart devices live once they’re connected?

Consider a guest or IoT network. Separating smart devices from your laptops and phones is what the NSA recommends, and it works the same way for 2.4 GHz-only devices, as long as that network includes 2.4 GHz. Our guide to putting smart home devices on a guest network covers the setup and what can break. For Matter and Thread devices, which can connect differently, see Matter and Thread, explained.

Fact-check notes

Bottom line

A smart device that won’t connect usually needs 2.4 GHz while your phone is on 5 GHz. Use a temporary fix first: eero’s pause button, or moving farther from a Google router. On Netgear and TP-Link, turning off Smart Connect works but changes your network permanently, so weigh it against Apple’s advice to keep one name. Once the device is connected, a guest or IoT network is a good place for it.

Short answer: MoCA is a standard for sending network traffic over coaxial cable, the kind installed for cable TV. A pair of MoCA 2.5 adapters can link a router to a distant room at up to 2.5 Gbps without new wiring. It works alongside cable TV and cable internet, but not on coax used by satellite TV, and you should fit a point-of-entry filter. This is a research-based guide, not a hands-on test.

MoCA is a way to send your home network over coaxial cable, the round screw-on cable installed for cable TV. If your house has coax outlets in the rooms where Wi-Fi is weak, a pair of MoCA adapters can turn that cable into a wired network link at up to 2.5 Gbps, with no new cable to run.

MoCA stands for Multimedia over Coax Alliance, the industry group that writes the specification and certifies products. This is a research-based guide. It draws on the alliance’s published specifications and on documentation from two adapter makers. We have not tested MoCA adapters ourselves, and the speed figures are specification and manufacturer claims.

How does MoCA work?

A MoCA adapter is a small box with a coax connector and an Ethernet port. One adapter sits next to your router, connected to it by Ethernet and to the wall by coax. A second adapter sits in another room, connected to that room’s coax outlet. The two adapters find each other over the coax in the walls and behave like a long Ethernet cable between the two rooms.

The reason this can share a cable with other services is frequency. Different signals travel on the same coax at different frequencies, the way radio stations share the air. The MoCA Alliance gives the technology’s overall operating range as 400 MHz to 1,675 MHz. Adapter maker goCoax says its MoCA 2.5 adapter works in the 1,125 to 1,675 MHz band, and describes cable internet’s typical upper limit as 1,002 MHz. MoCA sits above it.

To your router and devices, a MoCA link looks like Ethernet. There are no network names or Wi-Fi passwords involved.

How fast is MoCA?

The MoCA Alliance describes both figures as “actual data rates.” MoCA 2.5 is “backward interoperable with MoCA 2.0 and MoCA 1.1,” so mixed equipment will connect. Expect a link that involves an older device to run at the older device’s speed.

Three things decide what you get in practice:

• The adapter’s Ethernet port. A MoCA 2.5 adapter with a 1 Gbps Ethernet port can’t deliver more than 1 Gbps to the device plugged into it. For multi-gigabit speeds, look for a 2.5 Gbps Ethernet port. The goCoax MA2500D, for example, lists one 2.5GbE port.
• Shared capacity. Adapters on the same coax share one network, so heavy use in two rooms at once generally divides what is available.
• The coax itself. Old splitters, damaged cable and long runs reduce performance. We have no measured figures for how much, so treat 2.5 Gbps as a ceiling and not a promise.

For most homes this is academic. A plan of 1 Gbps or less fits comfortably inside a MoCA 2.5 link. See how much internet speed you need if you are sizing a plan.

Will MoCA work in my home?

Check four things before buying. If you have no usable coax, see whether powerline adapters are worth it instead.

The MoCA Alliance says the technology is “designed to co-exist with legacy services such as TV, DOCSIS, and cellular (4G/5G) technologies.” DOCSIS is the technology cable internet providers use.

If your internet arrives by fiber or a 5G gateway and the coax in your walls carries nothing, MoCA is the simplest case: the cable is yours to use.

Splitters matter too. MoCA signals reach 1,675 MHz, so every splitter between your adapters has to pass frequencies that high. An old splitter rated only to about 1,000 MHz can block or weaken the link. This follows from the frequency range above; check the rating printed on each splitter.

What do I need to buy?

• Two or more MoCA 2.5 adapters. One for the router end, one for each room. Choose adapters with a 2.5 Gbps Ethernet port if any of your equipment has 2.5 Gbps ports.
• A point-of-entry (PoE) filter. Check whether your adapter kit includes one before buying it separately.
• Short Ethernet cables. One per adapter. Our Ethernet cable guide covers which category to use.
• Possibly new splitters, if yours don’t pass MoCA frequencies.

We have left prices out because we only publish a price with the date we checked it.

Why do I need a point-of-entry filter?

Coax leaves your house. Without a filter, MoCA signals can travel back out along the incoming line. Hitron, which makes MoCA adapters, puts it this way: “MoCA filters block MoCA signals from leaking out of the home’s coaxial cabling,” and without one, signals can “interfere with neighboring MoCA networks or cable TV signals.”

The filter is a small barrel-shaped connector. Hitron’s instructions are to install it “at the point where the coaxial cable enters your home,” on the incoming line, ahead of the first splitter.

There is a security reason as well. The MoCA 2.5 specification added “Enhanced Privacy” with longer passwords, and the alliance describes a security feature called MoCASec for link privacy. Even so, a filter is the simple way to keep your network’s signals inside your own walls in the first place. Note that this “PoE” means point of entry. It is unrelated to Power over Ethernet, which shares the abbreviation.

How do I set it up?

1. Fit the PoE filter where the coax enters the home.
2. Connect the first adapter by the router. Coax from the wall to the adapter, Ethernet from the adapter to a LAN port on the router. If a cable modem needs the same wall outlet, use a splitter, or the adapter’s pass-through coax port if it has one.
3. Connect the second adapter in the other room. Coax from the wall to the adapter, Ethernet from the adapter to your device, switch or mesh unit.
4. Wait for the link light. Most adapters have a status light that shows a MoCA connection. If it stays off, the two outlets may not be on the same coax network, or a splitter may be blocking the signal.
5. Set up the security option if your adapters offer one, following the maker’s instructions.
6. Test the speed on a computer wired to the far adapter.

Is MoCA a good way to connect a mesh system?

Yes, where Ethernet isn’t available. A mesh unit connected through a MoCA adapter is using wired backhaul as far as the mesh system is concerned. That takes the unit-to-unit traffic off Wi-Fi, which is the main benefit of cabling a mesh system. Our guide to wired and wireless backhaul explains each brand’s cabling rules, and they apply here too.

If you have Ethernet jacks in the right rooms, use those. If you have coax in the right rooms, MoCA is the next best option. If you have neither, see mesh picks for large houses for systems suited to wireless-only homes.

Fact-check notes

Bottom line

MoCA turns coax you already have into a wired network link. It suits homes with coax outlets in the right rooms and no easy way to run Ethernet. Buy MoCA 2.5 adapters with Ethernet ports that match your equipment, fit a point-of-entry filter, and confirm nothing on that coax is satellite TV. If the link light comes on and a wired speed test looks right, you have the next best thing to Ethernet.

Short answer: For most homes, Cat 6 is the cable to buy: it supports 5 Gbps over 100 meters and 10 Gbps over shorter runs. Cat 5e you already own is fine up to 2.5 Gbps. Choose Cat 6A for in-wall runs if you want 10 Gbps at any length. Skip Cat 8, which is a short-range data center cable, and avoid copper-clad aluminum (CCA) cable whatever category is printed on it.

For most homes, buy Cat 6. It supports 5 Gbps over the full 100 meters (328 feet) and 10 Gbps over shorter runs, which covers every port on current home routers and mesh systems. If you already have Cat 5e, keep it: it is good for up to 2.5 Gbps. Choose Cat 6A when you are putting cable inside walls and want 10 Gbps at any length. Cat 8 is built for data centers and is not worth buying for a house.

“Cat” is short for category, a performance grade defined in cabling standards. A higher category is built and tested to carry signals at higher frequencies, which allows higher speeds or longer runs at a given speed. This guide draws on the IEEE Ethernet standards and on Fluke Networks, which makes the test equipment installers use to certify cabling. We have not tested cables ourselves.

How do the Ethernet cable categories compare?

100 meters is 328 feet. 55 meters is about 180 feet, 37 meters about 121 feet, and 30 meters about 98 feet. Lengths are for the whole link, including the patch cables at each end.

The 2.5 and 5 Gbps speeds come from an Ethernet standard, IEEE 802.3bz, published on October 18, 2016. It was written so that buildings already wired with Cat 5e and Cat 6 could go faster than 1 Gbps without new cable. That is why the 2.5 Gbps port on a current router works over older cable.

Is Cat 5e still good enough?

For most connections, yes. Fluke Networks says Cat 5e and Cat 6 are “both of which are typically able to support up to 1000 Mbps,” and that Cat 5e supports 2.5 Gbps over 100 meters. It adds that Cat 5e can carry 5 Gbps only in “defined use cases.”

So Cat 5e is fine for:

• An internet plan of 1 Gbps or less.
• A router or mesh system with 1 Gbps or 2.5 Gbps ports.
• Wiring mesh units together. Eero, for example, lists Cat 5e, Cat 6 and Cat 6A as suitable cables.

One caution applies to cable bundles. Fluke notes that Cat 5e and Cat 6 were never specified for alien crosstalk, which is interference between neighboring cables, and that it is “a limiting factor” at 2.5 and 5 Gbps. Long runs tightly bundled with other cables are where trouble shows up. A single cable from a router to a nearby device is not that situation.

Don’t rip out working Cat 5e. Replace it when a specific link needs to run faster than it can.

When do I need Cat 6?

Cat 6 is the sensible default for new cables. It supports 5 Gbps over 100 meters. It also carries 10 Gbps over shorter distances: under the industry guidance Fluke cites, 10 Gbps “should operate over channel lengths of up to 37 meters of Category 6 cabling,” and between 37 and 55 meters “depending on the alien crosstalk environment.”

Most runs inside a house are well under 37 meters. That makes Cat 6 a reasonable choice even if you expect to use 10 Gbps equipment later, with one caveat. Fluke says results over Cat 6 at 10 Gbps are unpredictable, with some 60-meter links passing and some 30-meter links failing, because interference varies from one installation to the next.

When is Cat 6A worth it?

When the cable is going somewhere hard to reach again. Cat 6A is the category designed for 10 Gbps, supporting it “up to 100 m (328 ft).”

Buy Cat 6A if:

• You are running cable inside walls, ceilings or between floors, and you want it to last through several generations of equipment.
• You have, or plan to buy, 10 Gbps equipment and a run is longer than about 37 meters.
• Many cables will run bundled together over a long distance.

Cat 6A cable is generally thicker and stiffer than Cat 6, which makes it harder to route around corners. For a short patch cable between a modem and a router, it brings no benefit over Cat 6.

Should I buy Cat 7 or Cat 8?

Cat 8: no. Fluke’s fact sheet says Cat 8 supports 25 and 40 Gbps Ethernet with a “maximum Channel length of 30m (100’)” at those speeds, and that “there is no unshielded variant.” Home routers, mesh systems, consoles and PCs do not have 25 or 40 Gbps copper ports, so a Cat 8 cable in a house runs at whatever lower speed the devices support. Cat 6A does the same job.

Cat 7: also no. Cat 7 is widely sold online, but it is not one of the categories in the US cabling standard. A summary of the current ANSI/TIA-568 standard by cable maker trueCABLE lists Cat 5e, Cat 6, Cat 6A and Cat 8 as the recognized copper categories. A cable labeled Cat 7 with ordinary RJ45 plugs will usually work as an Ethernet cable, but the label is not a rating you can check against that standard. Buy Cat 6 or Cat 6A instead.

Which cable matches my equipment?

Match the cable to the fastest port on the link. The link runs at the speed of its slowest part.

Check the port speeds in your router’s specifications, including the internet (WAN) port. A fast plan and a good cable still stop at 1 Gbps if the port does. If you are wiring a mesh system, see our guide to wired and wireless backhaul, and for sizing the plan itself, how much internet speed you need.

What should I avoid?

Copper-clad aluminum (CCA). Some low-priced cable uses aluminum conductors with a thin copper coating. Fluke Networks says cables with CCA conductors are “non-standards compliant,” because the standards require solid copper, and that they “often do not have a valid UL safety listing.” It also says aluminum’s resistance is “about 55% greater than for a copper cable of the same diameter,” which wastes power as heat when a cable carries Power over Ethernet (PoE), the feature that powers devices such as cameras and access points through the network cable.

Fluke suggests two checks anyone can do: weigh the box against a known copper cable, since aluminum is lighter, or scrape a conductor “to reveal the silver colored aluminum beneath the copper cladding.” Look for “solid copper” or “pure copper” in the listing, and treat a missing answer as a no.

Paying for a category you can’t use. A higher number does not make a connection faster than its ports. Cat 8 on a 1 Gbps port is a 1 Gbps link.

Flat or very thin cables for long runs. These are convenient under rugs and along baseboards, but we could not find them covered by the sources above, so we can’t vouch for their performance at multi-gigabit speeds. For anything long or permanent, use standard round cable from a maker that states the category and conductor material.

Does a better cable speed up my internet?

Only if the cable was the bottleneck. Replacing Cat 5e with Cat 6A on a 500 Mbps plan changes nothing, because Cat 5e already carries more than that.

A damaged or badly made cable is different. A link that should run at 1 Gbps but connects at 100 Mbps can point to a faulty cable or plug, and swapping it is a cheap test. If wired speed is fine and wireless is slow, the cable isn’t the issue; see why Wi-Fi can be slow when your internet is fast.

Fact-check notes

Bottom line

Keep the Cat 5e you have unless a link needs more than 2.5 Gbps. Buy Cat 6 for new patch cables and ordinary runs. Use Cat 6A for wiring that goes inside walls or needs 10 Gbps over a long distance. Leave Cat 7 and Cat 8 on the shelf, and make sure whatever you buy has solid copper conductors.

Short answer: Backhaul is the connection between mesh units. Wired backhaul uses an Ethernet cable, so the units stop spending Wi-Fi capacity talking to each other. Use it wherever you can run a cable; coax outlets with MoCA adapters are an alternative. If you can't wire anything, place units closer together and prefer a system with a third band. This is a research-based guide from manufacturer documentation, not a hands-on test.

Backhaul is the connection between the units of a mesh Wi-Fi system. Wired backhaul means the units are joined by Ethernet cable. Wireless backhaul means they talk to each other over Wi-Fi. If you can run a cable between units, wired backhaul is the better choice. If you can’t, wireless backhaul still works, and placement decides how well.

This is a research-based guide. It draws on the manufacturers’ own setup documentation for five mesh systems. We have not tested these systems ourselves, and the performance statements below are the manufacturers’ claims, labeled as such.

What is backhaul?

A mesh system has a main router, connected to your modem, and one or more extra units placed around the home. Brands call the extra units nodes, satellites or points.

Each unit does two jobs. It talks to your devices, such as phones, laptops and TVs. And it passes their traffic back to the main router. That second link, unit to unit, is the backhaul. When you stream video in a far bedroom, the data goes from the internet to the main router, across the backhaul to the bedroom unit, and then to your TV.

A weak backhaul limits everything behind it. A unit can show full signal bars on your phone and still be slow, because its own link back to the router is poor.

How do wired and wireless backhaul differ?

Wireless backhaul

With wireless backhaul, a unit receives data over Wi-Fi and sends it on over Wi-Fi. That traffic competes for airtime with your devices unless the system keeps it apart.

Some three-band (tri-band) systems reserve one band for backhaul. ASUS’s documentation, for example, says that on its tri-band AiMesh routers the second 5 GHz band is “a dedicated backhaul by default.” A two-band system has no spare band, so backhaul and devices share.

Wi-Fi 7 adds another approach, Multi-Link Operation (MLO), which the Wi-Fi Alliance says lets devices “transmit and receive data simultaneously over multiple links.” Some Wi-Fi 7 mesh systems apply it to the link between units. TP-Link, for example, says its Deco BE85 combines “wired and wireless backhaul with the power of Wi-Fi 7 Multi-Link Operation.” How each brand does this varies, so check the specific model.

Wireless backhaul depends on placement. Each unit needs a strong signal from the unit it connects to, so a unit placed in the dead zone itself has a poor backhaul.

Wired backhaul

With wired backhaul, an Ethernet cable carries the unit-to-unit traffic. TP-Link says of its Deco systems that this gives “lower latency and no bandwidth loss from a wireless hop.” Eero says Ethernet connections “maximize your internet speeds and reduce wireless interference.” Netgear says Ethernet backhaul “can improve your Orbi WiFi system’s performance if your router and satellites are placed very far apart.”

There is a second benefit on some systems. Once the units are cabled, the band that was reserved for backhaul can serve your devices. ASUS says that with its Ethernet Backhaul Mode turned on, that second 5 GHz band “has been opened to end devices.”

Wired backhaul also frees you to place a unit where coverage is needed, such as a detached office or a basement, even if no Wi-Fi signal reaches it.

Can I mix wired and wireless backhaul?

Yes, on the systems we checked. TP-Link says: “You can mix wired and wireless backhaul in the same network.” Eero says units without Ethernet ports “can be part of a mixed network of wired and wireless eeros.”

This makes a partial upgrade worthwhile. Wiring only the unit that serves your home office, or the one farthest from the router, improves that unit and leaves less wireless traffic for the others to share.

How do I set up wired backhaul?

The general steps are the same across brands. Then check the brand-specific rule in the table below.

1. Confirm your units have Ethernet ports. Some don’t. Eero says its Beacons and eero 6 Extenders have no Ethernet ports, and Google says Nest Wifi points “don’t have Ethernet ports and can’t be hardwired.”
2. Update the firmware on every unit. Netgear tells Orbi owners to do this before setting up Ethernet backhaul. ASUS’s Ethernet Backhaul Mode needs firmware version 386 or later.
3. Set the system up wirelessly first, if your brand says so. TP-Link’s instructions are to add all Deco units in the app first, then connect the cables.
4. Run the cable. Connect the main router to each unit, directly or through a switch. Eero specifies Cat5e, Cat6 or Cat6a cable; our Ethernet cable guide explains which to buy.
5. Let the system switch over. On Deco, TP-Link says no extra app configuration is needed, and the Wi-Fi backhaul between cabled units “disconnects automatically.” ASUS has you turn on Ethernet Backhaul Mode, and warns that every node must be cabled first or a node “might lose its uplink connection.”
6. Check the result in the app. Most mesh apps show how each unit is connected. Confirm it says wired or Ethernet before you tidy the cables away.

Cabling layouts

There are three common ways to cable a mesh system. Not every brand documents all three.

• Star. Each unit has its own cable back to the main router.
• Switch. The main router connects to an Ethernet switch, and the units connect to the switch.
• Daisy chain. The router connects to unit one, unit one connects to unit two, and so on.

Google’s rule catches people out. The order has to be modem, then the main Wifi router, then any switch, then the points. A point plugged into equipment that sits ahead of the main router will not join the mesh correctly.

What mistakes should I avoid?

• A slow link in the chain. Wired backhaul is only as fast as its slowest part. Netgear’s Orbi article notes that the Ethernet ports on the models it covers are rated at 1 Gbps and says to use switch ports of 1 Gbps or faster. If your internet plan and mesh units support multi-gigabit speeds, the switch and cables need to as well.
• The wrong switch. A basic unmanaged switch is the safe choice. TP-Link warns that “some switches, mainly the D-Link switches, will not forward packets based on IEEE 1905.1 protocol,” which Deco units rely on to find each other over Ethernet.
• A network loop. A loop forms when there are two cabled paths between the same pieces of equipment. TP-Link’s guidance stresses avoiding loops. Give each unit one cabled path back to the router.
• Assuming it worked. If a cable is damaged or in the wrong port, the system may quietly stay on wireless backhaul. Check the app.

What if I can’t run Ethernet?

Use the coax already in the walls. Our MoCA guide covers this in full. Many US homes have coaxial cable outlets from cable TV. MoCA (Multimedia over Coax Alliance) adapters send network traffic over that cable, with one adapter at the router and one at each mesh unit. The MoCA Alliance says the technology “delivers real world home networking speeds up to 2.5 Gbps.” That figure is the alliance’s own claim; results depend on the adapters and the condition of your wiring. From the mesh system’s point of view, a MoCA link is an Ethernet connection.

Improve the wireless backhaul. If cabling isn’t possible:

• Move units closer to the main router. A unit should sit where the signal from the router is still strong, roughly partway toward the weak area, not inside it.
• Reduce the walls and floors between units. Stairwells and open doorways help.
• If you are buying, a tri-band system leaves more room for backhaul than a dual-band one. Our mesh picks for large houses covers which systems suit wireless-only homes.

If you are not sure a mesh system is what you need, start with Wi-Fi router vs. mesh. And if a far room is still slow after cabling, the cause may be the device or its band, which our slow Wi-Fi checklist helps you find.

Fact-check notes

Bottom line

Backhaul is the part of a mesh system you don’t see, and it sets the limit for every unit beyond the main router. Cable it where you can, even if that is only one unit. Follow your brand’s layout rule, use a plain gigabit or faster switch, and confirm in the app that the units report a wired connection. Where cabling isn’t possible, try coax with MoCA adapters, and failing that, move the units closer together.

Short answer: Most US households are well served by a plan at or a little above the FCC's 100 Mbps download, 20 Mbps upload benchmark. A 4K stream needs 15 to 25 Mbps and a 1080p group video call about 4 Mbps in each direction, so even a busy evening adds up to well under 100 Mbps. Pay for more when you move large files often or several people upload at once.

Most US households need less speed than they are sold. A plan around 100 Mbps download and 20 Mbps upload handles several 4K streams, video calls and online games at the same time. Faster plans are worth it mainly when you download or upload very large files often, or when many people are online at once.

Speed here means megabits per second (Mbps), the unit on every internet plan. Download is data coming to you; upload is data you send. The way to size a plan is to add up what your household does at the same moment, then check the upload number separately.

What does the FCC count as fast enough?

The Federal Communications Commission (FCC) uses 100 Mbps download and 20 Mbps upload as its benchmark for fixed home broadband. It adopted that figure on March 14, 2024, calling it a four-fold increase from the 25/3 Mbps benchmark set in 2015. The FCC’s next report, released on August 14, 2026, kept the 100/20 Mbps benchmark.

The benchmark is a policy yardstick for measuring where broadband is available. It is not a rule about what you must buy, but it is a sensible reference point for a household.

How much speed does each activity use?

These are the service providers’ own recommendations, per stream or per call.

The FCC publishes a more general guide, last reviewed on July 18, 2022. It lists minimum download speeds for one activity at a time:

The FCC says of its own table: “These numbers are rough guidelines and are not based on surveys or experiments conducted by the FCC.” Treat every number here as a floor for one activity, not a guarantee.

Two things stand out. Ordinary online gaming uses very little speed; the FCC lists 4 Mbps. Cloud gaming, where the game runs on a remote server and is streamed to you like video, is the exception. And video calls are the one common activity where upload matters as much as download.

How do I work out what my household needs?

Add up the activities that happen at the same time on your busiest evening, then leave room on top. Here is a worked example using the FCC’s figures, which are the more generous ones.

That busy evening fits inside a 100 Mbps plan with more than a third to spare. Using Netflix’s 15 Mbps figure for 4K, the total falls to 42 Mbps.

The spare room matters because devices also do things you don’t see: phones back up photos, consoles and laptops download updates, and security cameras upload video. This is an estimate built from published minimums, not a measurement of any real home, so round up if you are unsure.

As a starting point, based on that arithmetic:

These ranges are our reading of the figures above. They are not an FCC recommendation. The FCC’s own Household Broadband Guide still describes anything above 25 Mbps as “advanced service,” but that page dates from July 18, 2022, before the benchmark rose to 100/20 Mbps.

Why does upload speed matter?

Upload is what you send: your camera on a video call, files to cloud storage, footage from a security camera, a live stream.

Zoom lists 3.8 Mbps of upload for a 1080p group call. Two people on calls at once need about 7.6 Mbps. That fits within a 20 Mbps upload speed, but it would crowd a plan with 10 Mbps of upload once backups and cameras are added. For the router settings that keep calls steady, see our guide to router settings for Zoom and Teams calls.

Plans are usually named for their download speed, so look for the upload figure too. Some connection types offer upload speeds far lower than their download speeds, while fiber plans often offer the same speed both ways. Our fiber vs. cable vs. 5G home internet guide covers the differences.

When is a faster plan worth paying for?

Mostly when you move large files. A stream uses a fixed amount of data per second, so extra speed does not improve it. A download uses everything available, so extra speed finishes it sooner.

Here is how long a 100 GB download, roughly a large modern game, takes at different speeds. This assumes the full plan speed for the whole download and nothing else using the connection, so real times will be longer.

The math: 100 GB is 800,000 megabits (100 × 1,000 × 8). Divide by the plan speed in Mbps to get seconds.

If you download a game like that once a month, the difference between 300 Mbps and 1 Gbps is about half an hour a month. If you do it weekly, or work with large video files, a faster plan starts to earn its price.

Does more speed fix lag or buffering?

Often not. Three things are commonly mistaken for a slow plan.

• Latency. Lag in games and delays on calls come from latency, the time data takes to make a round trip, measured in milliseconds (ms). NVIDIA, for example, requires less than 80 ms of latency to its data center for GeForce NOW, separately from its speed requirements. A faster plan does not lower latency.
• Wi-Fi. Your plan’s speed is delivered to the modem. The wireless link to each device is separate and often slower. If a laptop plugged into the router gets full speed and your phone doesn’t, the plan is fine. See why Wi-Fi can be slow when your internet is fast.
• An upload queue. One device uploading a large file can make everything else stutter. That is a router traffic problem, which our bufferbloat guide explains.

Before upgrading, run a speed test on a computer connected to the router by Ethernet cable. If the result is close to what you pay for and things still feel slow, more speed is unlikely to help. Our slow Wi-Fi checklist walks through the next steps.

How do I check what a plan really delivers?

Read the plan’s broadband label. The FCC requires internet providers to display these labels at the point of sale, and says they must disclose “broadband prices, introductory rates, data allowances, and broadband speeds.” Most providers had to comply by April 10, 2024, and providers with 100,000 or fewer subscriber lines by October 10, 2024.

On the label, check three things:

1. The speeds listed, for both download and upload. Compare them with your total from the worksheet above.
2. The price after any introductory rate ends. A cheaper plan at a faster speed is not cheaper if the rate rises later.
3. Any data allowance. A household that streams 4K daily can use a lot of data, and a cap changes the value of the plan.

Fact-check notes

Bottom line

Add up what your household does at once, compare it with the plan’s download and upload speeds, and leave some room. For most homes that points to a plan at or a little above 100 Mbps down and 20 Mbps up. Pay for more when large downloads or uploads are a regular part of your week. If things feel slow on a plan that already covers your total, look at Wi-Fi and latency before you look at a bigger plan.

Short answer: Use WPA3 Personal if every device you own can connect with it. If some can't, use the WPA2/WPA3 transitional (mixed) mode. Use WPA2 Personal with AES only when your router offers nothing newer. Avoid WEP, the original WPA and anything labeled TKIP. Whichever mode you use, a long passphrase and current firmware matter as much as the setting.

Use WPA3 Personal if every device in your home can connect with it. If some can’t, use your router’s WPA2/WPA3 transitional mode, which some brands call mixed mode. Use WPA2 Personal with AES only when the router offers nothing newer. Avoid WEP, the original WPA, and any option with TKIP in its name.

WPA stands for Wi-Fi Protected Access. It is the security that scrambles traffic between your devices and your router and decides who is allowed to join. This guide covers the “Personal” versions, the ones that use a shared Wi-Fi password at home. “Enterprise” versions use individual logins and are meant for workplaces.

What is the difference between WPA2 and WPA3?

The main difference is how each one handles your Wi-Fi password when a device joins.

With WPA2 Personal, a device and the router prove they know the password through a four-step exchange. Someone within radio range can record that exchange and then try password guesses against the recording on their own computer, as fast as their hardware allows. Security researchers describe this as a dictionary attack. A short or common password can fall to it.

WPA3 Personal replaces that exchange with one called Simultaneous Authentication of Equals (SAE). The Wi-Fi Alliance, the industry group that certifies Wi-Fi products, introduced WPA3 on June 25, 2018. It says SAE provides “stronger protections for users against password guessing attempts by third parties” and gives more resilient protection “even when users choose passwords that fall short of typical complexity recommendations.”

Protected Management Frames (PMF) guard the control messages that keep a device connected, which the Wi-Fi Alliance describes as protection from eavesdropping and forging.

The Wi-Fi Alliance now states that WPA3 is mandatory for Wi-Fi CERTIFIED devices, so current routers, phones and laptops that carry that certification support it.

Which setting should I choose on my router?

Router menus use different labels, so look for the closest match.

That order follows Apple’s router guidance, dated July 14, 2026, which also says: “Don’t create or join networks that use older, deprecated security protocols.”

The National Security Agency’s home network guidance, published in February 2023, gives the same advice from a different direction. It says to make sure your router “is capable of Wi-Fi Protected Access 3 (WPA3),” and that if you have devices that don’t support WPA3, “you can select WPA2/3 instead.”

Is transitional mode as secure as WPA3 only?

No. It is a compromise, and a reasonable one for most homes.

In transitional mode, the router accepts both WPA2 and WPA3 connections under one network name and one password. Any device that joins with WPA2 gets WPA2’s protection, not WPA3’s. And because the password is shared, a weak password remains exposed to the offline guessing described above through those WPA2 connections.

There is also a known attack on the mode itself. In April 2019, researchers Mathy Vanhoef and Eyal Ronen published a set of WPA3 weaknesses they named Dragonblood. One of them was a downgrade attack: an attacker sets up a fake WPA2-only copy of a network and pushes WPA3-capable devices to try connecting to it, which captures enough to start guessing the password offline. The researchers worked with the Wi-Fi Alliance on fixes, and patches were published. Newer versions of WPA3 include a feature called Transition Disable, which Cisco describes as protection against exactly this kind of downgrade. Whether your router and devices have it depends on their firmware.

What this means in practice:

• If every device you own supports WPA3, choose WPA3 only.
• If you need transitional mode, use a long passphrase. It closes most of the gap.
• Another option is to keep your main network on WPA3 and put older devices on a guest or smart-home network that uses WPA2 with AES. The NSA guidance recommends separating your primary, guest and smart-home networks anyway.

Is WPA2 still safe?

WPA2 Personal with AES is still acceptable when you have no better option. Apple keeps it on its recommended list for that case. Two conditions apply.

Your password has to carry more weight. Because WPA2 allows offline guessing, a short or reused password is the weak point. The NSA guidance says to use “a strong passphrase with a minimum length of twenty characters.” Several unrelated words strung together are easy to type and hard to guess.

Your devices need their updates. In 2017, security researcher Mathy Vanhoef disclosed KRACK, a weakness in WPA2’s four-way handshake. He wrote that the flaw was “in the Wi-Fi standard itself,” so “any correct implementation of WPA2 is likely affected.” It was fixed through software updates to devices and routers. His guidance at the time still stands: changing your Wi-Fi password does not fix it; installing updates does. A phone, laptop or router that stopped receiving updates before 2018 may still be exposed.

WPA3 is not flawless either, as Dragonblood showed. But the researchers who found those flaws wrote that, with vendors mitigating the attacks, WPA3 “will still be an improvement over WPA2.”

Do I need WPA3 for 6 GHz, Wi-Fi 6E and Wi-Fi 7?

Yes, for the 6 GHz band. Cisco’s WPA3 deployment guide, updated October 6, 2025, states that “WPA3 is mandatory for all Wi-Fi 6E devices operating in 6 GHz band” and that “WPA2 is not permitted in 6 GHz operation.” Protected Management Frames are mandatory there too. That guide is written for business networks, but the requirement comes from the Wi-Fi Alliance and applies to home routers as well.

Two practical effects:

• If you own a Wi-Fi 6E or Wi-Fi 7 router and the 6 GHz network doesn’t show up, check that security is set to WPA3 or WPA2/WPA3 transitional. The 6 GHz band can’t run on WPA2 alone.
• Wi-Fi 7’s Multi-Link Operation, which lets a device use more than one band at once, has stricter security requirements still. According to the same Cisco guide, a device that doesn’t meet them can’t connect as MLO-capable.

For what those bands and features do, see our guides to the 2.4, 5 and 6 GHz bands and Wi-Fi 6E versus Wi-Fi 7.

How do I check what I’m using now?

On a Windows 11 PC: open Settings, go to Network & internet, then Wi-Fi, and open your network’s properties. That is where Microsoft points users for connection details; look for the security type in the list. The exact wording can differ between Windows versions.

On the router: open the router’s app or admin page and look under wireless or Wi-Fi settings for “Security,” “Authentication” or “Encryption.” This is also where you change it. Menu names vary by brand.

How do I switch to WPA3 without breaking things?

1. Update the router’s firmware first. WPA3 support and its fixes arrive through firmware.
2. Choose WPA2/WPA3 transitional mode and save. Most devices reconnect on their own.
3. Check your older devices. Printers, smart plugs, older TVs and game consoles are the usual holdouts. If something can’t reconnect, “forget” the network on that device and join again.
4. Set a long passphrase while you are in the menu, if yours is short. You will have to re-enter it on every device, so do this once.
5. Move to WPA3 only later, once everything has connected reliably for a few weeks and you have confirmed each device supports it. If a device drops off, go back to transitional mode.

If a device can’t connect in transitional mode either, it likely needs an old protocol such as WPA with TKIP. Don’t lower the whole network’s security for it. Put it on a separate guest network, or replace it.

Security mode is one setting among several. Our router hardening checklist covers the admin password, automatic updates, WPS and remote management.

Fact-check notes

Bottom line

WPA3 Personal is the right setting when all your devices support it, and WPA2/WPA3 transitional mode is the right setting when they don’t. Plain WPA2 with AES is a fallback, and it leans hard on a long password and updated devices. If you use the 6 GHz band, WPA3 is not optional. Pick the strongest mode your devices can all join, set a passphrase of 20 characters or more, and keep the router’s firmware current.

Short answer: Your plan's speed applies at the modem; Wi-Fi is a separate wireless link to each device and is often much slower. Plug a laptop into the router: if that matches your plan, the slowdown is in the wireless path, usually distance, band, interference or one device.

Your internet plan’s speed applies at the modem. Wi-Fi is a separate wireless link between your router and each device, and that link has its own limits: distance, walls, the band it uses, interference, and what the device itself can do. That’s why a speed test on a laptop plugged into the router can look great while your phone crawls in the bedroom.

The good news is that this split also tells you where to look. Your provider is off the hook; the problem is somewhere between the router and the device.

How do I confirm it’s Wi-Fi and not my internet?

Plug a laptop into the router with an Ethernet cable and run a speed test. The FCC says a direct Ethernet connection gives the highest speeds. Verizon’s speed-test guidance suggests disconnecting any VPN and pausing streaming apps so the result is clean.

If the wired result is close to your plan, your internet is fine. Then run the same test over Wi-Fi next to the router, and again in the slow room. The size of the gap is your clue.

Say you pay for 500 Mbps. A wired laptop gets 480. Your phone gets 60 in the bedroom two walls away. The internet is fine; the phone’s wireless link is the weak point.

What actually slows Wi-Fi down?

Distance and walls

Signal weakens with distance and with each wall or floor it crosses. Brick, concrete, metal and large appliances are the worst. The FCC recommends putting the router in a central location. In Tom’s Guide’s September 2026 tests, mesh kits that managed 1.4 to 1.9 Gbps at 15 feet fell to between 20.8 and 150.1 Mbps at 90 feet in a brick, multi-story home.

The wrong band

The FCC says 2.4 GHz is also used by many household devices, so it can be crowded. The 5 GHz band offers faster speeds and may be less crowded by neighbors’ networks, though it doesn’t carry as far. A phone sitting on 2.4 GHz in a room with a clear 5 GHz signal is a common cause of “slow Wi-Fi, fast internet.”

The device itself

Older phones, laptops and smart TVs have slower Wi-Fi radios. A device that supports only an older Wi-Fi standard can’t use the speed a newer router offers, however fast your plan is. This is why one device can be slow while others are fine.

Neighbors and interference

If your router’s Wi-Fi settings show a long list of nearby networks, the FCC says their signals could affect your performance. In apartment buildings, that often shows up in the evening.

Too many devices at once

The FCC notes that when many wireless devices share a Wi-Fi network, it can affect performance. A few video calls, a game download and several 4K streams can saturate the wireless side even when the internet connection has room.

The router

An older router, one with outdated firmware, or one tucked in a cabinet can be the bottleneck. Apple recommends setting routers to install firmware updates automatically. If you use a combined modem-router from your provider and it’s several years old, it may be a limiting factor too.

Settings

Apple recommends using one network name across all bands, leaving the channel on automatic, and setting the radio mode to allow all Wi-Fi versions (it lists “All” as preferred) so each device can connect at the fastest mode it supports. Apple also suggests a 20 MHz channel width for 2.4 GHz. A router that was set to an older, restricted mode can hold back newer devices.

How can I see what my device is actually connected to?

Look at the device’s Wi-Fi details. Menu names vary by version, so treat these as starting points.

• Windows: open Settings, go to Network & internet, then Wi-Fi, and open your network’s properties. It lists the network band, the Wi-Fi protocol and the link speed.
• Mac: hold the Option key and click the Wi-Fi icon in the menu bar. It shows the channel, the Wi-Fi mode and the transmit rate.
• Phones: iPhone and Android screens differ by model. If a phone isn’t giving details, a free Wi-Fi analyzer app can show the band and signal strength.

Two things to look for. First, is the device on 2.4 GHz when 5 GHz is available? Second, is the Wi-Fi mode an older one? The link speed shown is the maximum the radio link is currently negotiating, and real download speeds are typically lower, so don’t expect to see your full plan speed there.

What should I do about it?

Work from the cheapest fix up:

1. Move closer, or move the router. If speed jumps near the router, it’s coverage.
2. Move the slow device to 5 GHz. Forget the network and rejoin, or move closer so it chooses 5 GHz.
3. Update the device and the router. Both matter.
4. Check what else is using the network and pause big downloads.
5. Wire what stays put. TVs, consoles and desktops are better on Ethernet.
6. Add coverage. If the far room is simply too far, a mesh node placed halfway between the router and that room usually works better than one placed in the room itself. See our router-versus-mesh guide.
7. Replace the router only after the above. An old router that no longer gets updates, or one that’s slow even beside it, is a fair candidate.

What this means for you

If only one device is slow, fix that device first. If every device is slow in the same room, it’s coverage. If everything is slow, even next to the router, look at the router, its settings and your neighbors’ networks.

A faster internet plan won’t help a Wi-Fi problem. Fix the wireless link before you pay for more speed. To check whether your plan is big enough in the first place, see how much internet speed you need.

Bottom line

Fast internet and slow Wi-Fi aren’t a contradiction. They’re two different links. A cable test splits them apart, and the device’s own Wi-Fi details show what’s really happening on the wireless side.

Short answer: Start with a wired speed test. If a laptop plugged into the router is also slow, the problem is your plan, modem or ISP; if it's fast, the fix is usually router placement, the Wi-Fi band, interference or a single device. All of those are free to check before you buy anything.

Start with a wired speed test: plug a laptop into your router with an Ethernet cable and run a speed test. If that result is far below your plan, the problem is your modem, plan or provider. If it’s fine and Wi-Fi is slow, the problem is in the wireless path, and the steps below will find it without spending money.

The order matters. Most “slow Wi-Fi” advice jumps straight to buying hardware. This sequence tells you whether you need any.

How do I find out where the slowdown is?

1. Run a wired test

Connect a laptop to the router with an Ethernet cable. The FCC says a direct Ethernet connection gives the highest speeds and avoids Wi-Fi congestion, which makes it the best baseline.

For a clean result, Verizon’s speed-test guidance suggests disconnecting any VPN and pausing video or music streaming during the test. Run it two or three times, since a single result can be off.

Compare the number to your plan. If it’s close, your internet service is working. If it’s well below, restart the modem (step 5), check whether your provider has an outage, and then contact them.

2. Test Wi-Fi next to the router, then in the problem room

Run the same test on Wi-Fi standing near the router, then in the room where it’s slow. The gap tells you what you’re dealing with:

3. Check whether it’s one device or all of them

If every device slows down at the same time, the problem is upstream of any one device: the router, modem or provider. If only one phone or laptop is affected, start with that device.

4. Check how many things are using the connection

Cloud backups, game downloads, 4K streams and security cameras all share your connection. The FCC notes that when multiple wireless devices use the same Wi-Fi network, performance can suffer. Pause big downloads and test again.

5. Restart in the right order

Unplug the router and the modem. Plug the modem in first, wait for its lights to settle, then plug the router back in. Microsoft’s support guidance notes that the lights tell you when each device is ready. If the modem’s lights stay on after you unplug it, it may have a backup battery you need to remove.

A restart is a diagnostic, not a cure. If you need one every few days, something else is wrong, and the steps below are where to look.

6. Move the router

The FCC recommends putting the router in a central location. Get it out of cabinets, off the floor and away from large metal objects and thick walls. A router in a corner of the house spends half its signal on the yard.

7. Check which Wi-Fi band you’re using

The FCC says 2.4 GHz is also used by many household devices, while 5 GHz offers faster speeds and may be less crowded by neighboring networks. The trade-off is that 5 GHz doesn’t reach as far through walls.

Apple recommends giving every band the same network name so devices can choose, and notes that if you split them into separate names, devices may not connect reliably. If a device keeps landing on 2.4 GHz, check its Wi-Fi details (see our guide on Wi-Fi that’s slow when the internet is fast).

8. Leave the channel on automatic, then check neighbors

Apple recommends letting the router pick the Wi-Fi channel automatically, since it will select the best one for you. The FCC notes that if your router’s Wi-Fi settings show many other networks nearby, your performance could be affected by them. In a crowded apartment building, that’s often the cause of evening slowdowns.

9. Update the router’s firmware

Apple recommends setting routers and access points to install updates automatically. Updates can fix stability and performance bugs and close security holes. If your router is older and no longer gets updates, that’s a real reason to consider replacing it.

10. Wire the devices that stay put

A TV, game console or desktop doesn’t need Wi-Fi. Running Ethernet to it frees up wireless capacity for phones and laptops. If you can’t run cable, the FCC says adapters are another route.

When should I replace my router or call my provider?

Call your provider when the wired test is slow, when the modem’s lights show a problem, or when many devices are slow at once and a restart doesn’t help.

Consider new equipment only when your wired speed is good, the router is well placed and updated, and Wi-Fi is still weak in parts of the house. At that point, the question is coverage, and our router-versus-mesh guide covers it. Also consider replacement if the router no longer receives firmware updates.

What this means for you

Say you pay for 500 Mbps. A wired laptop tests at 480 Mbps, but your phone in the upstairs bedroom gets 40 Mbps. Your internet is fine. The phone is a few walls and a floor away from the router, possibly stuck on 2.4 GHz. Moving the router or adding a node halfway is the fix. A new, faster plan would change nothing.

Bottom line

Test with a cable first, then work from the cheapest fixes to the most expensive: restart, move, check the band, update, wire what you can. Most slow Wi-Fi gets better before you reach the buy-new-gear step.

Short answer: Use 5 GHz for most phones, laptops and TVs. Use 6 GHz for newer devices that are close to the router. Leave 2.4 GHz for far rooms and for smart-home devices that support nothing else. In most homes the best setup is one network name for all bands, so each device picks for itself.

Most devices should be on 5 GHz. Use 6 GHz for newer devices that sit close to the router, and leave 2.4 GHz for far rooms and for smart-home devices that support nothing else. If your router uses one network name for all its bands, your devices are already making this choice, and for most homes that is the right setup.

The rest of this guide explains why the bands behave differently, which devices can use each one, and which router settings are worth changing. It covers the rules that apply in the United States; channel availability differs in other countries.

What is a Wi-Fi band?

A band is a range of radio frequencies. Wi-Fi uses three of them, and a router has a separate radio for each band it supports. The band is not the same thing as the Wi-Fi generation:

Not every router of a given generation has every band. Some Wi-Fi 7 routers are dual-band and leave out 6 GHz, so check the box for the words “tri-band” or “6 GHz.”

How do the three bands compare?

Sources: 47 CFR 15.247 and 15.407 for frequency ranges; Netgear Support for relative coverage, speed and household interference. “Coverage” and “speed” are general rankings, not measurements from our own testing.

The pattern is a trade. Lower frequencies carry farther and pass through walls more easily. Higher frequencies have more spectrum available, which allows wider channels, and wider channels carry more data.

When is 2.4 GHz the right choice?

The 2.4 GHz band is 83.5 MHz wide in the US. That is small. A standard Wi-Fi channel is 20 MHz wide, and network engineers have long worked with only three channels that don’t overlap each other: 1, 6 and 11. In an apartment building, every neighbor’s router is sharing those three channels with yours.

The band is also used by other things. Netgear’s support documentation lists microwave ovens and garage door openers among the household devices on 2.4 GHz.

Use it when:

• The device is far from the router. A weak 5 GHz signal can be worse than a moderate 2.4 GHz signal.
• The device supports nothing else. Some smart plugs, bulbs, cameras and older printers have a 2.4 GHz radio only. Check the product’s spec sheet.
• The device needs very little data. A thermostat or a doorbell sensor does not need a fast link.

Apple recommends setting the 2.4 GHz channel width to 20 MHz. A 40 MHz channel would take up about half of the 83.5 MHz band, which makes interference with neighbors more likely.

When is 5 GHz the right choice?

For most devices, most of the time. The 5 GHz band has far more spectrum than 2.4 GHz, which means more channels, wider channels and fewer neighbors on the same one. The FCC’s home network tips, published in March 2020, advised switching the devices you depend on for work or school to the 5 GHz network where possible.

Two things to know:

It doesn’t reach as far. A 5 GHz signal loses more strength through walls and floors than a 2.4 GHz signal does. If a device two floors from the router keeps dropping, this is often why.

Some channels are shared with radar. FCC rules require Wi-Fi equipment using the 5.25 to 5.35 GHz and 5.47 to 5.725 GHz ranges to detect radar and avoid it, a feature called Dynamic Frequency Selection (DFS). On those channels a router has to listen for radar and move if it hears any. This is normal behavior and a good reason to leave channel selection on automatic.

When is 6 GHz the right choice?

The 6 GHz band is the newest and by far the largest. The FCC opened 1,200 MHz of it, from 5.925 to 7.125 GHz, to unlicensed use in rules adopted on April 23, 2020 that took effect on July 27, 2020. Cisco describes that as more than twice the Wi-Fi bandwidth of the 5 GHz band.

That room is what makes it fast. The Wi-Fi Alliance says the band has space for up to seven 160 MHz channels. Wi-Fi 7 adds 320 MHz channels, and three of those fit in 1,200 MHz (1,200 ÷ 320 = 3.75, so three that don’t overlap). For the buying decision, see Wi-Fi 6E vs. Wi-Fi 7.

It is also uncrowded for a simple reason: only Wi-Fi 6E and newer devices are allowed there. There are no old, slow devices taking up airtime.

The limits:

• Shortest reach. Netgear ranks 6 GHz as providing the least coverage of the three bands. Part of the reason is regulatory. FCC rules cap the power density of indoor 6 GHz access points at 5 dBm per MHz, and client devices such as phones at −1 dBm per MHz. Expect 6 GHz to be most useful close to the router.
• Device support. Your device needs a Wi-Fi 6E or Wi-Fi 7 radio. Apple’s list, for example, starts at iPhone 15 Pro, MacBook Pro models from 2023 and MacBook Air models from 2024. Check your own device’s specifications.
• Newer security. Cisco notes that the Wi-Fi Alliance made WPA3 security mandatory for Wi-Fi 6E devices. If your router’s 6 GHz network isn’t appearing, check that WPA3 is enabled. See WPA2 vs. WPA3.

Some mesh systems use 6 GHz in a second way: as the wireless link between units. Our mesh guide for large houses covers that.

Which band should each device use?

These are starting points. If a device is on the “right” band and still slow, the band isn’t your problem; work through our slow Wi-Fi checklist instead.

Should the bands share one network name?

In most homes, yes. Apple’s router guidance recommends a single network name (SSID) across all bands, and says its devices perform best on Wi-Fi 6E and Wi-Fi 7 networks when the 2.4, 5 and 6 GHz bands share one name. With one name, each device picks a band and can change as you move around.

Separate names make sense in two cases:

1. Setting up a 2.4 GHz-only smart device. Some setup apps can fail when the phone is on 5 GHz. A temporary 2.4 GHz-only name, or a router’s “IoT network” option, gets around that. Our step-by-step guide for 2.4 GHz smart devices covers each router brand.
2. Troubleshooting. Forcing a device onto one band is a quick way to test whether the band is the cause of a problem.

If you do split them, expect to manage the choice yourself. A phone that joined the 2.4 GHz name will stay on it even when it is standing next to the router.

Which router settings are worth changing?

Apple publishes a list of recommended router settings that works well as a general baseline. The band-related ones:

Source: Apple Support, “Recommended settings for Wi-Fi routers and access points,” published July 14, 2026. Menu names vary by router brand.

How do I check which band a device is using?

• Mac: Hold the Option key and click the Wi-Fi icon in the menu bar. The channel line shows the band.
• Windows: Settings, then Network & internet, then Wi-Fi, then the properties for your network. Look for “Network band.”
• Android: Settings, then Wi-Fi, then tap the connected network. Most phones show the frequency.
• Any device, including iPhone and iPad: Your router’s app usually lists each connected device with its band.

Exact menu names change between software versions.

Bottom line

Let your devices choose by using one network name, keep 2.4 GHz narrow at 20 MHz, and leave channels on automatic. Expect 6 GHz to help only newer devices near the router, and expect 2.4 GHz to be slow but dependable at a distance. If one band is weak across much of the house, the problem is coverage, and our router-versus-mesh guide is the next step.

Short answer: Bufferbloat is the lag you get when a busy connection makes data wait in a long queue. Test it with a speed test that measures latency under load, then turn on your router's smart queue or SQM feature and set it a little below your real speed. Wiring your console or PC also removes WiFi from the equation.

If your game or video call gets choppy whenever someone uploads a video or a device starts a big update, you may have bufferbloat. It is one of the most common causes of lag on otherwise fast connections, and it can often be fixed with one router setting.

What is bufferbloat?

Your router sends data to your internet provider through a connection with a fixed speed. When that connection fills up, extra data waits in a queue. If the queue is long, everything behind it waits too, including your game packets. That wait is bufferbloat, and it shows up as latency spikes.

How do you test for it?

1. Plug a computer into your router with Ethernet so WiFi doesn’t affect the result.
2. Close other apps, then run a bufferbloat test such as Waveform’s or Cloudflare’s speed test.
3. Look at latency under load, not just the download number. A big jump from your idle ping means bufferbloat.

If you’re not sure whether your slowdown is WiFi or your plan, see our slow WiFi test guide.

How do you fix it?

1. Find the setting. Look for Smart Queue, SQM, Adaptive QoS, or similar in your router’s app. Names differ by brand, and not every router has one.
2. Set the speeds a little below your real speeds. Use 85% to 95% of your tested download and upload speeds. This keeps the queue in your router, where it can be managed.
3. Run the test again. Latency under load should be much closer to your idle ping.
4. Wire what you can. Consoles and PCs that stay put should use Ethernet.

Which routers help?

If you are deciding whether a gaming-branded router is worth it, see do you need a gaming router.

Look for a router that lists smart queue management or SQM, or one that supports third-party firmware such as OpenWrt. When we review routers like the Asus RT-BE92U, we check where the QoS controls live and how easy they are to find.

What if it’s your WiFi?

If the wired test is fine but WiFi spikes, the cause is probably distance, interference, or the band your device is using. Try the free fixes in our guide to why WiFi is slow when your internet is fast.

Short answer: Don't put a Wi-Fi extender halfway to the dead zone. Walk toward the dead zone with a phone and place it where you still have two bars, which is often two-thirds of the way, and check the extender can hear the router on 5 GHz.

The common advice — place the extender halfway between your router and the dead zone — assumes uniform signal loss. Walls and floors don’t lose signal evenly, so halfway by distance is often wrong by walls.

A better method

Walk from your router toward the dead zone with a phone showing signal strength. Stop at the point where you’re still at two bars, not one. That’s your extender spot, even if it’s two-thirds of the way there rather than half.

The 5GHz trap

Extending on 5GHz only helps if the extender itself has strong 5GHz reception from the router — otherwise you’re relaying a weak 5GHz signal and making things worse. If your two-bar spot only gets a strong 2.4GHz signal, use that band for the backhaul even though it’s slower.
