I have a 4402 wlc, ACS 3.3 and we use Microsoft client with WPA-TKIP/MSChapv2.
We hardly connect to the WLAN, but after 10 minutes we are disconnected.
We are migrating from LEAP to PEAP, so we create two profiles in the WLC.
LEAP connects good, but PEAP fails.
In the ACS log I can see a double authentication request.
