How to check your internet speed

Restart your modem and router.

To ensure your CenturyLink internet speed test is as accurate as possible, restart your modem and router. This fresh start will restore them to full working capacity.

Turn off connected devices and apps.

Every device that is connected to your internet uses bandwidth and slows your internet speed. Before starting the internet connection speed test, disconnect or turn off any connected devices, including phones, computers, and smart home devices.

Pause all downloads.

Make sure your computer isn’t downloading any files or updates that would use up bandwidth while you run the internet speed test. Check for apps or downloads running in the background with the Task Manager or Activity Monitor.

Conduct multiple speed tests.

An internet connection speed test will only tell you how fast your internet is at that moment, not how fast it is consistently. Run multiple speed tests at different times throughout the day to get a more complete picture.
