## 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.

## Key takeaways

- Apple recommends setting the channel to Auto, so the router picks the best one. Netgear and ASUS routers also choose channels automatically by default.
- In the US, 2.4 GHz has three channels that don't overlap: 1, 6 and 11, according to Cisco Meraki's channel planning guide.
- Some 5 GHz channels are DFS channels shared with radar. If a router detects radar, it must leave the channel, which can briefly disconnect devices.
- Eero picks channels automatically and adjusts them over two days to a week, because channel changes can briefly disrupt connections. It doesn't offer a manual setting.

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.

| Symptom | Likely cause | Try first |
|---|---|---|
| Slow or dropping at certain times, fine at others | Interference from nearby networks | Change channel, or move devices to 5 GHz |
| Weak in one far room all the time | Distance or walls | [Fix dead zones](https://wifiweekly.com/guides/find-and-fix-wifi-dead-zones/) |

## 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](https://wifiweekly.com/guides/2-4-ghz-vs-5-ghz-vs-6-ghz-wifi/).

**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.

## 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.


## Frequently asked questions

### What is the best Wi-Fi channel?

There isn't one best channel for every home, because it depends on what nearby networks use. Apple recommends Auto. If you choose manually on 2.4 GHz, pick 1, 6 or 11.

### Should I set my Wi-Fi channel manually?

Only if you have problems that look like interference and Auto isn't solving them. Netgear advises keeping the default settings unless you experience interference.

### What are DFS channels?

DFS channels are 5 GHz channels shared with radar systems. A router using one must check for radar and switch channels if it detects any, which can briefly disconnect devices. ASUS lets you include or exclude DFS channels from automatic selection.

### Can I change the channel on eero or Google Nest Wifi?

Eero doesn't offer a manual channel setting; it selects channels automatically and changes them infrequently. Google's help pages describe Nest Wifi and Google Wifi choosing bands automatically and don't describe a manual channel setting.

### Will changing the channel fix a dead zone?

Usually not. A dead zone is mostly about distance and walls. Moving the router or adding an access point helps more.
