What exactly is the problem? Did the AP that got the IP address not join the controller? To join the controller, the AP needs to either be on the same layer 3 subnet, use DHCP Option 43, be able to resolve, "CISCO-LWAPP-CONTROLLER" from the DNS address you supply via DHCP, or, you can create a helper address and forward udp port 12223 to your controller's management address.
