I have several VISTA/Intel WLAN PC's that cannot connect to the WLAN via a 1230AG AP. It works fine when the OS is XP. I am using LEAP to a Juniper SBR appliance for authentication.
The credentials authenticate on the radius server and the authentication accept is sent via the WAP to the client PC. But the client PC never agrees that it is authenticated. I have searched Intel, Microsoft and Juniper with no luck.
