Although the US models of the cAP-AC "RBcAPGi-5acD2nD" are stated on the product page "cAP ac-US (USA) is factory locked for 2412-2462MHz, 5170-5250MHz and 5725-5835MHz frequencies. This lock can not be removed."
These devices force country profile "unitedstates3" which refuses any other 5Ghz frequency than 5180.
Was I lied to in the product details, am I doing something wrong, or is this a bug?
Based on my research anything between 5745-5825MHz (channels "149" through "165") is wide open for use. DFS is not required for this block.
