Open a command prompt and type ipconfig/all. The gateway address is the IP address of your router.

I performed steps ipconfig /all and my deault gateway is 192.168.1.1. I changed the router name from WRT54G2 to my Network name. Is that the problem why I cannot get to the admin window?

How do I get to the admin window to go back in and change it back to what it was?
