Eric shows you how to reset a Linksys router to factory settings. This works for all the Linksys routers and modem router combos.
There is a pin hole on the back or bottom of the router with a button inside. You'll want to find a pointy sharp object, such as a pen or safety pin, to press into the hole and hold the button down.
1. Make sure the power is plugged in!
2. Then hold the button down for at least 10 seconds
The router will not have factory default password and settings applied, just like when it came new from the store!
