How to test your WiFi and internet speed

To truly understand how fast your internet is, follow these steps:

Close all applications and power down all devices that use the internet

If you have lots of devices connected to your internet, then your internet speed test results could be lower than you expect.

Connect directly to your modem

Use a computer that is connected to your modem through an ethernet cable. If you run a speed test using your WiFi, the speed test results could be inaccurately low.

Run the speed test

Run the speed test to see what your upload and download speed is. We recommend running the test multiple times to account for any fluctuations in speed that you may experience.

Disconnect from any VPNs

This speed test will not complete while connected to a VPN. In order to complete this speedtest you must disconnect from your VPN.
