Hi Dan,
We have seen a similar issue if "Fast SSID change" is disabled, which it is by default. This is configured on the "Controller -> General" section. Eric J.

A client with an Android device (HTC One) is able to associate to a wireless access point joined to a Cisco WiSM1 controller that is running 7.0.235.3 code, but when the AP is joined to a WiSM2 with 7.5.0 code it is unable to join. The most I have heard that it attempts to connect until ultimately it gives up. If the AP is migrated back to a WiSM1 the issue clears and the client is able to associate, receive and IP address, and use the network. The WLAN is an open SSID currently operating without any security so we know that isn't interfering. A TAC case has been opened to investigate this issue, however I wanted to see if anyone else has experienced this yet. Typically I wouldn't give it much thought, but it we have also seen some of our student base experience this same issue with a Windows 8 tablet (not sure if it was RT or not). Where my colleague and his HTC one is able to move the AP back to a WiSM1 and work around the issue, the student doesn't have that luxury as all APs in his/her residence hall are 2602e APs and require a WiSM2 controller. After experiencing this issue we are hesitant to move other residence halls currently operating on WiSM1s to the new WiSM2 controllers. Thanks much!
