How to test your AT&T internet speed
- Connect a computer to the AT&T gateway with an Ethernet cable for the most accurate result, or stay close to it on WiFi.
- Pause streaming, downloads and video calls on other devices.
- Press START above to measure download, upload, ping and jitter.
- Compare your result with your AT&T plan and repeat the test at a different time of day.
What speed should you get from AT&T?
AT&T offers three very different types of home internet, so the right result depends on which one you have. Plan names and speeds change over time and by address.
| Service | Typical download | Typical upload |
|---|---|---|
| AT&T Fiber | about 300 Mbps – 5 Gbps, depending on plan | Same as download (symmetrical) |
| AT&T Internet Air (5G home internet) | roughly 75–225 Mbps | roughly 10–30 Mbps |
| AT&T Internet (DSL / copper) | up to about 100 Mbps, often much less | a few Mbps up to about 20 Mbps |
With AT&T Fiber, a wired test should come close to your plan speed in both directions. If upload is much lower than download on fiber, something is limiting the connection.
Why is my AT&T internet slow?
- WiFi instead of Ethernet – multi-gig fiber plans can only be fully used over a cable and with fast network cards.
- Gateway location – the gateway is often installed where the fiber enters the house, far from the living areas.
- Distance on copper lines – DSL speeds drop the farther you are from AT&T’s equipment.
- Signal and congestion on Internet Air – 5G home internet depends on signal strength and how busy the local tower is.
- Background usage – updates, backups and streams on other devices.
How to fix slow AT&T internet
- Restart the gateway from the Smart Home Manager app or by unplugging it for 60 seconds.
- Test on Ethernet to separate line problems from WiFi problems.
- Improve WiFi coverage with AT&T’s Smart WiFi extenders or a mesh system if wired speed is fine.
- For Internet Air, place the receiver near a window on the side of the house facing the tower, as shown in the app.
- Check for outages in the AT&T app or website.
- Contact AT&T with your test results if wired speeds stay well below your plan.
To change WiFi settings, most AT&T gateways open at 192.168.1.254 – see our router login guide.
Frequently asked questions
Why is AT&T Fiber upload as fast as download?
Fiber carries data equally well in both directions, so AT&T Fiber plans are symmetrical. It’s a big advantage for video calls, cloud backups and content creators.
Can I get 5 Gbps over WiFi?
No current WiFi device reaches multi-gig speeds in real use. You need a computer with a 5 Gbps or 10 Gbps Ethernet port and a matching cable to see those numbers.
Is this the official AT&T speed test?
No. WiFiTest is an independent tool that measures your connection to the nearest Cloudflare server.
