my problem is that sometimes a APs is disassociating from the WLC what problem can it be?
AP 'AP-01' disassociated from Controller '10.10.10.11'.
AP 'AP-01', interface '802.11a' is down on Controller ''.
APs connected to Cisco 3750 PoE Switches
a lot of APs
can it be the problem, that i don't have configured a primary and secondary WLC?
