Have C35 controller, 5*AP3805e and 5*AP3805i.
Ap3805i normally working.
AP3805e don't up radio interfaces.
When I manually type "On" in Radio->Admin Mode, after "Save" Interfaces automatically became "Off"
May be it's something wrong with default antenna-gain value?
Antennas - WS-ANT-5DIP-2 and WS-ANT-2DIP-2
