We have access points spontaneously jumping between 2 controllers. When this happens, the WLAN associations on the radios are lost. Each time an AP jumps to the other controller, the WLAN is re-assigned to the radio and the configuration is saved. This is highly problematic because the WLAN that is lost is our voice WLAN and calls are being droppped. Can anyone explain why this is happening?
We are running software version 188.8.131.52 on the WiSMs and using 1252 (a/b/g/n) access points.
Any help would be greatly appreciated.
