Hi all,
I have numerous of AP 3602i units connecting to a single WLC 5508 in FlexConnect mode. Two out of 46 AP units have been disassociating with WLC randomly. The only way to bring them back is to do a "shut/no shut" on switch port connecting to these AP units. I have to do this many times during my work days and am very tired now. Called Cisco and provided many logs but no help....sometimes problem disappear for couple days then come back. All AP units are at remote sites and communicated to WLC via MPLS network. Please help this poor guy.
Thanks for all comments.
