I Have a problem when make a replacement of  AP 1142 with the new one on existing WLC deployment.

The AP already get IP Address, Option43 and 60 already set.

ip dhcp pool AP
   network 10.1.254.0 255.255.255.0
   option 43 hex f104.0a01.fb0b
   default-router 10.1.254.1
   option 60 ascii "Cisco AP c1140"

AP already download the image from WLC, but after AP restarting, it change to discovery state again. Here's the log

*Aug 12 05:56:35.889: %CAPWAP-3-ERRORLOG: Go join a capwap controller

The log keep repeated itself.

Clock on AP wont synchronized to WLC too, everytime I set a clock on AP, it will back again 2 hours from WLC clock. The funny thing si the other old AP can join to WLC with no problem

Anyone have any idea about this one?

Many Thanks,

Andrew

Console into the AP and in enable mode, enter the command "lwapp ap controller ip add ".

AP already download the image from WLC,

Your AP currently have two IOS:  One called the "recovery" and the other is the LWAPP/CAPWAP.  The recovery is easily identifiable because it has the letters "rcv" in the filename.  In enable mode, delete the LWAPP/CAPWAP and reload the AP.  Make sure the AP is not connected to the network.

Once the AP boots the "rcv" image, perform the following commands:

1.  clear lwapp private

2.  clear lwapp ap controller ip address

Reboot the AP and let it join the network.
