Welcome to Cisco Support Community. We would love to have your feedback.

I've successfully migrated AP to LAP mode and connected them to a new WLC 4402.
I've also installed WCS software.
Into WLC logs I see no errors.
Into WCS I see every 15 minutes, one error for any LAP, that indicate that that LAP is disassociated from Controller, but in controller no signal about this problem.
AP 'ap-190' disassociated from Controller ''.
Every thing into wireless networks seems to work fine.
Go to Monitor APs > New Search > Search By > All Unassociated APs. See if the ones that you are receiving alarms for are there. If they are and the name begins with APxxx remove them and the alarms should go away.
