Are the APs on the same subnet as the WLC on a different subnet?
Where the APs previusly joined to another WLC or was the WLC using a different IP address on the managment interface?
If the AP was joined to a previous WLC or the WLC had a different IP address you could try to reset the AP to defaults using the follwoing procedure.
1.Desconect the AP from the network.
2.Do a power cycle.
3. When the access points loads the soiftweare log in (default password: Cisco)
4. Run the command: Show flash

13 -rwx 5 Mar 1 2002 23:21:56 +00:00 private-config
If you see 2 images one is the recovery and looks like:
There could be another image that is the image downloaded from the WLC and this one is the
one we need to remove:
For erasing this image we use the command:
delete /recursive flash:
delete /recursive flash: c1130-k9w8-mx.123-7.JX2
This way the access point Hill reboot with the only abalable image in this case
But the private-config has not been erased (Here is where the AP IP and WLC IP is saved),
for erasing this we use the following command:
AP1130#clear lwapp private-config
After this we are able to reconfigure the AP with the correct information:
AP1130#lwapp ap hostname AP1240
AP1130#lwapp ap ip address 10.77.244.199 255.255.255.224
AP1130#lwapp ap ip default-gateway 10.77.244.220
AP1130#lwapp ap controller ip address 172.16.1.50
