Can’t get my wireless on through my blanc router

I recently bought a blanc network router and havent been able to get wireless through it. I had trouble just getting the access points connection to work through it. I am using windows xp with service pack 3 and my modem is a speedtouch. I have my computer I am attempting to connect to right next to this computer and im using a d-link 802.11g wireless card. This has been driving me crazy for about 2 months so im finally going to turn to some1’s much needed help.
