How to Get an Accurate Result from Your CenturyLink Internet Speed Test?

Several factors could affect the performance of your CenturyLink Internet due to which the speed may show up as slow when you test it out. It could be the time of the day, background processes eating up on the bandwidth, an excessive number of connected devices, or another variable.

That is why it is necessary to not draw any conclusions after running an internet speed test on your CenturyLink connection only once. Run it multiple times at various times of the day and take care of the following aspects:

Restart Your Modem/Router & Connected Devices

The most standard trick to set technical glitches right!

Reboot your internet equipment and also the device you’ll be running the CenturyLink Internet speed test on. Let the hardware take a brief pause, get rid of any temporary bugs, and start afresh!

Remember WiFi is Slower Than a Wired Connection!

WiFi speeds cannot be as fast as wired. And if you’ve ever noticed, speed claims are usually accompanied by a disclaimer that says advertised speed estimates are based on a wired connection.

So when you run a speed test to compare with what you expect to receive, run it on a wired connection. Use the latest gen Ethernet cable (Cat5e, 6, 7 or 8) to connect your device to the modem directly.

Pause Your Internet Activities

Close down webpages and applications on your computer or another device(s) before you start the test ― including any music & video streaming platforms, software patch downloads, or file uploads.

Limit the Number of Connected Devices

Disconnect any devices not actively engaged in online tasks ― its preferable to not have devices idling on your home network as you run your CenturyLink speed test ― smartphones, TVs, tablets, and wireless cameras ― all fall in the category.

Pick the Closest Server

A good speed test should make the right pick automatically. But technology is vulnerable to imperfection. And often for rural locations, the wrong server gets picked. Beware of this and use the opportunity to pick the one closest to you.

Clear Your Browser Cache

Its best to clear your browser cache before you run a speed test ― especially if you’re doing it more than once. This way you’ll eliminate any chunky files left behind by the preceding test.
