Why Is My Upload Speed So Slow? Causes and Fixes

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.
