Problem WLAN controller 4400

There is a WLAN controller 4400 which controls the access points. There is a collapse of all access points from 00:00 to 00:12.
The link is working properly, no problems with the AC, the point is not restarted.

Re: Problem WLAN controller 4400

If your WLC firmware is 5.X then I would like to recommend you upgrade to 6.X.
