Well.. i tried to connect to some more APs.. and it seems to have problem only with D-link APs.. it weird but when i try to connect to friends Linksys or Ovislink it works well even with WPA, but if i try to connect to my D-link DWL-900AP+ or D-link DAP-1160 it doesnt.. dont know where could be a problem, i could connect to these APs with XP just fine..
