Check your internet speed

Find out how to use the AT&T Speed Test to measure your internet connection speed.


About the AT&T Speed Test

The AT&T Speed Test shows you your baseline speeds. Baseline speeds are determined by using the 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 performs 2 key measurements:
  • Download speed (the speed of data sent from the internet to your device)
  • Upload speed (the speed of data sent from your device to the internet)

Find out how speed test results relate to your AT&T Internet service speed.

Detailed steps for testing your internet speed

How to test your network speed:
  1. Make sure the only thing connected to the internet is the device you’ll be testing. Disconnect all other devices connected to your network to avoid Wi-Fi congestion, even if they aren’t using internet.
  2. Go to the computer or device where you want to test your internet speed.
  3. If testing over Wi-Fi:
    • Make sure the wireless device has a clear line of sight, approximately 10 feet from your Wi-Fi gateway. Devices that use older standards like 802.11b or 802.11g can’t get faster speeds.
    • Disable any device that may create wireless interference.
  4. Close other apps on your device.
  5. Run the AT&T Internet Speed Test.
