Hi
To convert your IAP-205 to a campusAP, your controller needs atleast to be on version 6.4.1.
Seems like you have a 3200, this will be problematic, as this controller does not have a large enough flash to support the newest code base.
You will either have to switch to å newer controller or buy a upgrade kit for this 3200, making it a 3200XM
