Pesquisando cheguei a esta solução de contorno:
Recently had an issue with a Cisco 5508 WLC where RLDP was enabled and the clients were complaining of being disconnected several times a day.
Jumped directly onto the AP via SSH and went through the logs and could see message’s like the following every 2/3 minutes:

Fix/Workaround
The Fix is too disable RLDP or enable only for MonitorOnly (Listen) APs:If you go Security Tab –> Wireless Protection Policies –> Rogue Policies –> General
You will find the following setting:
Either mark for Disable or MonitorModeAPs
