How to Check Your Internet Speed

Before you run any of these tests, be sure to: ; Turn off any downloads or uploads you have going on your system. That includes streaming media or live video meetings or torrents. Rebooting the system is a good start. ; Log out of your VPN software for the duration of the test; it adds a lot of overhead to the connection. ; For real accuracy, plug your PC directly into the router via Ethernet. You'll have a lot less network overhead than you would with a Wi-Fi connection.
