We have cisco wlc 2125 with 13 AP 1131g. All works good. But after power failure one AP can not join to controller, only reset help to recover connection AP to WLC. Additionally, we don't have access to rs-232 port on AP. In this moment on WLC we can see DISCOVERY request from AP and response from WLC to AP, but AP don't send JOIN to controller. Does anyone has the same issue as me ?
You can really only tell what is happening from the console port of the AP. other than that your just guessing. If a reset is what fixed it, just keep that in mind for that AP.
