I recently upgraded our Cisco 4402 & 4404 controllers from 184.108.40.206 to 220.127.116.11 and everything went fine until 24hrs later all the access points disassociated and would not re-connect.
The AP's sit with a single fast flashing green light. We are running a combination of 1131AG and 1241's.
Has anyone else seen this issue? It seems like it could be DHCP related as the leases are 24hrs.
