Wireless Problems

I just upgraded to Windows Vista. Im on a network, the master computer is on xp (with the router attached) and all the other computers/laptops are on xp except mine. its a wireless network and for some reason, after installing my wireless adapter on vista, it now says when i try to connect "the capability of your network adapter does not match the requirements of this network" how do i connect?

the network is there, but whenever i try to connect it just says "the capability of your network adapter does not match the requirements of this network". Does the master computer with the router need to upgrade to vista or does the router need drivers or something?
