Run an internet speed test

Once your GFiber internet is up and running, you may want to run a speed test to make sure you’re getting the best performance possible. You can run a speed test from any wired or wireless device on your network by following the steps below, though you’ll get the fastest possible speeds if you’re using a wired connection.

Some important things to note

Most web browsers max out at about 3 Gigabits per second, so if you’re on the 5 Gig or 8 Gig plan, a browser-based test may not capture your full speed. If this sounds like you, please skip down to the run a speed test with the Ookla Speedtest desktop app section.

If one of your devices is slower than expected, you can always run a speed test directly in your GFiber account or in the Google Fiber app — just open your browser and go to https://fiber.google.com/speedtest. Running a speed test this way will allow us to be able to help you troubleshoot your network.

Run a speed test in your web browser

You can run a speed test using your browser by following the steps below:

1. For the best results, we recommend closing all other applications and devices before running the speed test.
2. You can run a speed test over Wi-Fi or with a wired connection. If you’re running a wired speed test and you have a Wi-Fi 6E Router or a Multi-Gig Router, make sure your device is either connected to the silver 10G LAN port on the back or to your Fiber Jack.
3. If your internet was just installed and you want to test your new speeds, open your browser and go to https://speedtest.net.
4. If you think your internet is moving slowly and want to check your speed, open your browser and go to https://fiber.google.com/speedtest.

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

5. Click the GO button to start the test. 
   
6. The speed test will measure your download speed first, followed by your upload speed. When it finishes, you’ll see a report on your download and upload speeds, as well as information about your ping — which measures how quickly your device gets a response from the server (lower is better) — and jitter — which measures fluctuations in the speeds at which data is sent (lower is better).
   

Run a speed test with the Ookla Speedtest desktop app

If you’re on the 5 Gig or 8 Gig plan, a browser-based test may not capture your full speed. You’ll need to run a speed test with the Ookla Speedtest desktop app and a router and device that are capable of delivering multi-gig speeds.

If you have the GFiber Wi-Fi 6E Router or the Google Fiber Multi-Gig Router, you’re all set. if you’re using your own router we recommend having at least the specs described in this article. We also suggest using a computer with a 10 Gbps network interface card or USB adapter.

For more information, you can check out how to get the most out of our 5 Gig plan or how to get the most out of our 8 Gig plan.

1. Click on the links below to download the Ookla desktop app:
   • Speedtest for Mac
   • Speedtest for Windows
2. To get the best results, we recommend closing all other applications and devices before running the speed test.
3. Use a wired Ethernet connection to obtain the maximum speed. If you have a Wi-Fi 6E Router or a Multi-Gig Router, make sure your device is either connected to the silver 10G LAN port on the back or to your Fiber Jack. (If you don’t have an Ethernet connection, you can perform the speed test over Wi-Fi using a web browser or the Google Fiber app.)
4. Launch the Speedtest by Ookla app.
5. Click the GO button to start the test. Make sure you're connected to GFiber's speed test server by clicking "Change Server" for the best results.
   
6. The speed test will measure your download speed first, followed by your upload speed. When it finishes, you’ll see a report on your download and upload speeds, as well as information about your ping — which measures how quickly your device gets a response from the server (lower is better) — and jitter — which measures fluctuations in the speeds at which data is sent (lower is better).

Run a speed test in the Google Fiber app

1. Touch Network .
2. Touch Run speed test. Speed test screen will open.
   
    
3. Touch the   button to run a speed test.                        

 

Some speed test tips

You won't be able to reach the maximum internet speeds of your GFiber plan when you're connected by Wi-Fi (we recommend connecting using a wired connection if you want to reach the highest speeds). You can learn more about the maximum possible download speeds on a variety of wireless and wired devices in Maximum internet speeds on GFiber.

Before running a speed test:

• Connect your laptop to its power adapter.
• Update your device (phone, laptop, tablet, etc.) to the latest version of its operating system.
• Use the latest version of your web browser to run the speed test. You can learn more about supported browsers in Supported operating systems and browsers.
• Use an Incognito window if you're using Chrome as your web browser, or a private window if you're using a different web browser.
• Make sure you have only one tab open in your web browser.
• If possible, run the speed test on a recent model computer with up-to-date networking hardware.

Troubleshoot your network connection

If you tested your internet speed and feel it's slower than expected, you can learn more about how to improve your Wi-Fi speeds. You can also check out our network troubleshooting steps to help resolve any issues you may have with your GFiber internet connection.
