I recently upgrade one of our WLC's from V4.2.207 to V6.0.188 which seemed to have gone well without problems, however, when my test AP connects to that wlc, it receives the new image fine from the controller, but when it reboots, it connects to another controller which has v4.2.207 and downgrades it's image. Once it reboots again, it connects to the test controller and the cycle continues. It has a SSC which I have allowed and there does not seem to be any clear reason why this is happening!!
I have forced the primary controller on the AP to the test controller management address but the AP still manages to try connect to a different controller.
Any ideas on why this is happening??
In the log, I am getting quite a few "Received LWAPP packet with invalid sequence number", and the following messages:-
