Help with wireless to wired routers

I am trying to get my wireless G Belkin router to work with my Linksys wired router. The Linksys is the main router which has the direct connection to the cable modem. For some reason the Belkin won't show up on the DHCP client table nor can I access it by using the default IP. All i want is to use the wifi from the Belkin so my Wii can access the internet. Any suggestions on what to do?
