Pro Tip: For best results, use an Ethernet cord to connect your router or modem directly to your device before you run the test.

Using the speed test

  1. Click “Go” to begin the speed test. The test will first measure your download speeds in Mbps, followed by your upload speeds. 
  2. For the most accurate results, perform the test on a device that is plugged directly into the modem using an Ethernet cable
  3. Disconnect any devices, including computers, phones and other smart devices that may be using bandwidth and interfere with your results.
  4. Wait for the test to finish to view your results.

Can I take the speed test using a Wi-Fi connection?

This speed test is intended to give you an idea of what speeds you are getting from your provider, but you can also use it to test your Wi-Fi connection. Note that using a Wi-Fi connection will not be an accurate test of the speeds you are getting from CenturyLink, but it will be a good indicator of how your Wi-Fi router and devices are performing.

If your Wi-Fi speeds are significantly lower than your plan’s advertised speeds, try resetting your router or any of these tips to boost your Wi-Fi signal. Sometimes the best way to improve your speeds is to upgrade to a faster plan. You can shop available high-speed internet plans in your area with Allconnect
