I have deployed 3 Cisco 1142 APs in a conference room with 130 people.
The APs are configured on DCA for channels 1,6,11.
I would expect the APs to automatically spread among these 3 channels and instead I have 2 APs on 1 and 1 on 11.
Please, do not answer, "DCA is not reliable". I have extensive case studies from Cisco discussing the advantages on choosing DCA over manual channel selection.
