I have currently setup with 1200 series AP's as a Stand alone, the authentication is done via radius with Certiface Installed in Client Domain Laptops (WPA2 + AES). The certificate is installed on the domain laptops and when I connect wireless it shows up as WPA2 (Peap). As we migrating to WLAN Controller we unable to authenticate the client with WPA2 AES. In controller if we enable PSK ( Preshared key) its works fine. with 802.1x the authentication not happening and I am getting the error as RADIUS is not responding. But we dont have a control with RADIUS which is in Remote Site. Can some one guide me in RADIUS what needs to check, and with IOS AP its works fine.
Thanks in Advance
