AT&T Internet Speed Test

Want to know your Internet speed?

    The speed test takes less than a minute and performs two key measurements:
  1. Download speed (the speed of data sent from the Internet to your computer)
  2. Upload speed (the speed of data sent from your computer to the Internet)

  3. We also report latency, a factor that could influence your speed.
