I need to reset my router because no one remembers

To do a factory reset on the WGT624:

Unplug the power to the router
Take a paperclip and hold the "Reset" button on the rear
Plug the router back in while holding down the reset button
Wait 20 seconds, and let go of the rest button

To log into the router, open up your web browser and type "192.168.0.1" in the address bar. The default username is "admin" and the default password is "admin".

Once you log in you will be able to reconfigure the wireless security.

There is a small pin size hole beside the ports use a paper clip to reset it.
Good luck
