How can I test my download and upload speeds?

How to Run a Speed Test

You’ll want to run the test on a computer that’s connected to your modem by an Ethernet cable.

  • Cat 5e or higher Ethernet cable is required to ensure your wiring isn’t limiting your speed. That designation is often printed on the cable itself, along with other specifications. Cat 5e has been around since 2001, so it’s unlikely you’re using an older cable.
  • Speed is shared across all devices in the home, so disconnect other devices from your network.
  • Use the latest version of Mozilla Firefox, Internet Explorer, Google Chrome or Safari.
  • Verify the latest version of Adobe Flash Player is installed on your computer.
  • You might need to enable Flash on the Speed Test page. For example, to enable Flash in Chrome:
    • If you go to the speed test tool and see a message stating that Flash is required, in the address bar click Secure, and for Flash, select Always allow on this site.
    • Refresh your browser, wait a few moments, and the speed test will be displayed instead of the message.

Test Your Internet Speed.
