hi,

my problem is that sometimes a APs is disassociating from the WLC what problem can it be?

error:

AP 'AP-01' disassociated from Controller '10.10.10.11'.

AP 'AP-01', interface '802.11a' is down on Controller ''.

my system:

APs connected to Cisco 3750 PoE Switches

2x WLC4404

a lot of APs

any idea?

can it be the problem, that i don't have configured a primary and secondary WLC?

thx
