802.1a is admin down. wlc 4402 and ap1252

Hello all,

I am trying to enable the 802.11a and use the 5Ghz band in my house. However, I am having difficulty in doing this. Please see screenshot below. I have select AU (Australia) as my regulatory domain (2nd image). 802.11a band is enabled(3rd image), but the interface is still down (1st image). Australia regulatory code is -Z. Not sure why -A and -N are showing up

In the cli, the dot11 radio interface is down. This might be the issue? If so, how would I turn this on from the wlc management page?

Note: I've tried other regulatory domains - US, US and Mexico, but to no avail.

note 2: now, both radio interfaces are admin down.

Console into the AP and post the output to the command "sh version". 

I am suspecting the AP has the regulatory domain of "-A".

Does the A in AIR-LAP1252AG-A-K9, signify the regulatory domain?

I am located in Australia.

If you're in Australia then the Regulatory Domain should be "-N".   And this is the main reason why 802.11a radio is disabled.
