Look for a small Reset button on the back, front or the bottom of your Linksys router. The location of the button depends on the router model, so look carefully. As a precaution the buttons are small and inconspicuous, so that users do not accidentally reset their routers.
Once you have located the Reset button, press and hold it for at least ten seconds. You may need to use something with a small point, such as the end of a paperclip or a pencil tip to depress the button. Release the button and wait for the router to start back up. This will restore the router to its initial factory settings as it was when you first set it up. You will need to configure it again and choose a new password. Refer to the first article in this series for instructions on how to do so.
