AT&T Speed Test
Run a free AT&T speed test built for AT&T subscribers in United States. Measure your download speed, upload speed, ping and jitter, and benchmark the result against typical AT&T broadband and fiber plans.
How to read a AT&T speed test
- Run the test on this page for download, upload, ping and jitter.
- Repeat at peak evening hours. A large drop usually means congestion, not a broken line.
- If games or calls lag despite high Mbps, run the bufferbloat test.
- Compare household needs on how much speed do I need.
AT&T subscribers in United States can use this independent browser test as a second measurement alongside any official AT&T tool.
Frequently Asked Questions
How do I test AT&T internet speed accurately?
Connect with Ethernet if you can, pause other downloads, and run three tests: off-peak, evening peak, and once on WiFi. Compare download, upload and ping — not a single Mbps number.
Why is my AT&T speed lower than the plan?
WiFi overhead, peak-hour congestion, router limits and other devices sharing the line are more common than a fully failed circuit. If Ethernet off-peak is still far below the plan, gather screenshots and contact AT&T support.
Does a AT&T speed test replace the official ISP test?
Use this test to understand real-world performance. For a formal dispute, also keep results from AT&T's official tester if they provide one.
