Porblem networking XP with vista whn WPA2 on

by rob l. . Updated 19 years, 1 month ago

I have a XP desktop and VIsta laptop that will not network when I turn on WPA or WPA2 (they will netwrok if no security or WEP used.) Also, I have a XP laptop that will network with the XP desktop with WPA(2) on? Any Ideas on how to network the XP computers with the vista with the WPA(2) on?

Thanks!
