resetting a belkin wireless G router

I accidently set my router up as an access point. It gave me this info
Specify IP Address 192.168.2.254
subnetmask 255.255.255.0

then reset the router. Obviously that was a mistake on my part. I need to know how to set it back.

I have two computers, a laptop used for the wireless connection from that router and a desktop plugged into the router. The router is plugged into the cable modem i have.

Once more, everything was working just fine until i made my router to be used as an access point which i now regret doing.

Please help.
