Perform a Google Fiber speed test

Run a Fiber speed test to check your Internet speed of up to 1 gigabit.

You've probably used speed test sites to check your Internet connection speed, but many sites are not designed for ultra-fast services like 1 Gig. To enable you to accurately measure your connection speed, we built a speed test that can handle Fiber.

To test your connection speed:

  1. For the best results, close all applications before running the Internet speed test.

  2. Open your browser and go to

    If you have pop-ups blocked, the speed test may not appear when you click the speed test link. If this occurs, unblock pop-ups temporarily to display the speed test page.

  3. Click the go button to start the test.

Speed test Google

For best speed test results, here are some helpful tips:

  • This speed test is designed specifically for hardwired Google Fiber connections. Using this speed test for other types of Internet connections can produce unreliable results.
  • You won't be able to reach maximum Internet speeds of your chosen Fiber plan when connected by Wi-Fi. Learn more about the maximum possible download speeds achieved using 1 Gig service on a variety of wireless and connected devices.
  • Update the device with the latest version of the operating system.
  • Use the latest version of your web browser to run the speed test. Read about supported browsers.
  • Turn hyperthreading on (Note: this is not supported on MacBook or Lenovo devices running Chrome web browser).
  • Use an Incognito window in Chrome web browser or a private window in other web browsers.
  • Have only one tab open in your web browser when running a speed test.
  • If you have Fiber TV service, remember that both TV and data come into your home through your Fiber Jack, and TV takes priority. To maximize results, run the speed test when you're not recording any programs and turn off your TV Box.
  • If possible, run the test on a recent model computer with up-to-date networking hardware.
  • If you've run a Google Fiber Internet speed test and believe you still aren't receiving fastest speeds, here are ways you can improve your Wi-Fi speeds.
