How to remove password

The router's administrative passwoord or a password for using the Wireless Access Point (WAP)?

Do you know the existing password?

Are you able to use a computer that uses a wired connection to the router?

Are you willing to reset the router to factory settings? Does it have a reset button like many other routers?

Have you checked the owner's manual (may be CD based)? Many manufacturers have downloadable manuals in the support section of their web site if you've lost the paper or CD version that came with the equipment. You might need the router's model number.
