Using the CenturyLink speed test
Click “Start Testing Speed” to begin the speed test. The test will first measure your download speeds in Mbps, followed by your upload speeds. Wait for the test to finish to view your results.
For the most accurate results, perform the test on a device that is plugged directly into the modem using an Ethernet cable. Disconnect any devices, including computers, phones and other smart devices that may be using bandwidth and interfere with 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 it to upgrade to a faster plan. You can shop available high-speed internet plans in your area with Allconnect.

Why is my downloading speed so slow?
There are many things that can affect internet speeds, such as peak usage hours and the number of connected devices. Wi-Fi speeds are also often much slower than advertised plan speeds.
