AP 1242 units at other sites work fine when going from Autonomous to LWAPP, but one APs at one site alone are giving problems. They join the WLC and very shortly reboot and keep doing the same over and over agin.
In the attachments just look at AP1242 whoce MAC address is 00:1a:e2:53:0f:aa
The screen shot of WLC is attached when the AP joined it. And also output of show ap summery is attached to confirm that the AP is joining with WLC for few minutes and getting rebooted.
