1. Open the preferences for your router.
Often, the preferences are set in your web browser, via a URL with numbers (example: http://192.168.0.1 or http://192.168.1.1). You may need a password.
If you're like us, and you set the router password long ago and cannot remember it now, you can often reset the password to the manufacturer default by pressing a button on the router itself.
Or preferences may be set via specific application for your router, which you installed on your computer when you added the router.
Please write down your current settings before entering the OpenDNS addresses, just in case.
