How this test measures
The test runs against the nearest Cloudflare data center, shown above as the server. Results describe the path between you and that server, which can differ from the path to a particular website, game or call server.
Ping is the median round-trip time of 60 small requests, and jitter is the average difference between consecutive ones. Download and upload use files of growing size sent one after another over a single connection, and the result is the 90th percentile of the requests that ran long enough to be reliable. Speeds are in megabits per second (1 Mbps = 1,000,000 bits).
Because it uses one connection, the test can read lower than a multi-connection test on very fast or distant links. Wi-Fi, a VPN, other devices and a busy browser can all lower the result, so use a cable and close other apps for the most accurate number. Nothing from the test is stored on our servers.
Powered by Cloudflare's network. No account needed.
Run the test below to see what your AT&T connection delivers: download speed, upload speed, ping and jitter. It takes about 30 seconds.
What speeds to expect on AT&T
AT&T sells three different kinds of home internet, and what is normal depends on which one you have. AT&T Fiber is symmetrical, so upload is close to download. Internet Air is home internet over a wireless signal, and its speed varies with signal strength and how busy the local network is. Older copper service is slower and varies with distance from the equipment. Check your plan or bill to see which one you have.
- Fiber. A wired test should land close to your plan, with upload near download.
- Internet Air. Place the device near a window and test at different times, because results move with signal and local demand.
- Copper service. Speeds depend on distance, so a lower result than the headline plan is more common.
Plans and names change by area, so check your AT&T account or bill for the exact speeds you pay for.
How to test your AT&T speed accurately
- Use Ethernet. Connect a computer directly to the modem or router. Wi-Fi often hides what the line can really do.
- Check your equipment. Fast plans need a modem and router that support those speeds. Older equipment is a common reason for low results.
- Stop other traffic. Pause downloads and streaming on other devices, and turn off any VPN.
- Test at different times. Run the test in the morning and again in the evening to see whether speed changes with demand.
The test here measures to the nearest Cloudflare server. AT&T's own speed test measures inside its own network, so the two numbers can differ slightly.
If your AT&T speed is slower than your plan
- Test wired and on Wi-Fi. If wired matches the plan, the problem is your Wi-Fi.
- Restart the modem and router. Unplug both for 30 seconds, plug in the modem first, wait for it to settle, then the router.
- Check the cables. Make sure the connections are tight and the Ethernet cable is in good condition.
- Look for a pattern. If it is only slow at certain times, the stability test can help you show that.
- Contact AT&T if wired speeds stay well below your plan. Share your test results with them.
