CISCO AIR-AP1252AG-E-K9 cannot set 40 Mhz channel bandwithd

[diaconescugabriel]

Hello i have an Cisco ap and i can not activate channel bonding on 5Ghz Interface

I set the channel 116 in 5Ghz at 40Mhz but i says the active channel is 116 at 20Mhz (DFS enabled but)

i atached to this thread the print screens

How can i setup the channel bonding on cisco air 1252.

Thank you.

Does it have enough power ? (it requires more than normal poe)

Please collect "show controllers d1" on command line (telnet or whatsoever) and possibly also the console output when AP boots.

it is on power supply is not PoE
