Will the AIR-AP1252AG-N-K9 N Class AP work with the 4400 WLAN controller?

I have this problem too.

Well the 1250 should work as long as you're on a code of 4.2 or later.

But since you are asking about a "N-K9" which I understand to be a non-fcc AP, I'm not really sure how that works. So the real question here is, what is the different inregards to registering with controllers when it comes to FCC,ETSI,Korea,etc.. configurations

Hi Troy,

Just to add a note to the great info from Wesley (+5 points my friend :)

The model of 1252 that you have,AIR-AP1252AG-N-K9 is the Autonomous version so it will have to be upgraded to LWAPP. You also need this minimum code version on the WLC/WCS;
