About the AT&T speed test

The AT&T speed test shows your baseline speeds. These are determined by using AT&T servers closest to you to measure the speed between your devices (including computers, smartphones, tablets, game consoles, and smart TVs) and the internet. The speed test takes less than a minute and checks two key measurements:  

Download speed (speed of data sent from the internet to your device)

Upload speed (speed of data sent from your device to the internet)

Test your internet speed

Test your device speeds:

Go to the computer or device you want to test. Disconnect all other devices on your network to avoid Wi-Fi® congestion, even if they aren’t using internet.

If testing over Wi-Fi:

Make sure the wireless device has a clear line of sight, about 10 feet from your Wi-Fi gateway or All-Fi™ Hub. Devices using older standards like 802.11b or 802.11g can’t get faster speeds. 

Disable household devices that may create wireless interference, such as Bluetooth® devices, wireless phones, baby monitors, and other wireless video devices.

Close apps on the device you're testing.
