Cannot connect DI-524 to VISTA

Hello! I have bought a router D-Link DI-524 and wired it to my modem so all of the computers at home would have wireless connection. I have two laptops, one with XP and the other one a brand new VISTA. The problem is that I could connect the XP laptop to it with no problem and installing nothing on it, just like that! When trying to connect my VISTA laptop to it, after installing all of the drivers the new computer had to install, I culd not see any wireless connections. Is it possible that DI-524 is not compatible with VISTA? Or should I make some changes on the connection configuration. I have read something here about DI-524 but nothing seemed to help me solve my problem before asking! Please help me, so I won't have to buy a new router. Thank!
