If you don't know the default username/password for your router, go the the website for the company that made your router and look it up in the support section.



If you or someone else changed the password on the router, and you don't know that it is, look up the instructions on how to do a full reset of your router so it will go back to factory defaults. You'll have to set the router up again, but the password will be changed back to the default.
