Hmm, I dunno whether this will work for Linksys but it did for my D-link router.
1. Reset the router by pressing the 'reset' button at the back of the router.
2. Insert the IP address into the navigation bar, which is usually
http://192.168.0.1/3. Insert the default username, which is 'admin', leave the password field blank.
4. You should arrive at the Linksys page, where you can change a new password for your router.
Mayi should be able to answer your question if the above fails.
