We have a wlc 4402 (IOS 22.214.171.124) with a few LAP1131 associated to it.
All the APs are located in different cities (one per city) and every AP is connected to a trunked Fa0 of an 877 router, that provides to the APs its IP address as well as the IP address of the wlc's management interface.
The problem is that for some cities, the following happens:
1 - AP sends DISCOVERY_REQUEST;
2 - WLC receives the request and sends the DISCOVERY_RESPONSE;
3 - AP receives the DISCOVERY_REPLY;
4 - AP sends the JOIN_REQUEST;
5 - AP reloads as it DID NOT GET JOIN RESPONSE.
In other cities, the AP associates, equalizes the firmware, downloads all the wlans configurations without a glitch.
In all the cities envolved, we have the same AP, with the same IOS, the same 877 router all with the same IOS, and this is driving us crazy, as the problem does not occur for all the sites.
Can anybody out there shed some light into this issue?
We already digged the forum, but could not get any hint that would help us to solve this puzzle.
Thanks in advance,
