Guys,
I've ran into an issue that I haven't seen before. A client of mine has a WLC that manages AP's at several different sites on the East Coast. They are all connected via a multilinked T1x2 connection. One site in particular contains 7 AP's, and users at this site are unable to connect. The remaining sites have no issue at all connecting. I noticed that when users began reporting this that all AP's had failed interference profiles. Also, when I instruct a user to attempt a connection, I don't ever see their mac address come across a debug session on the controller, which I find odd. Is it possible that a neighboring business is sending deauth packets and containing my AP's?
The client is running code version 4.2.61.0.

When this happens, check the syslog on the controller. You will need to do this quick becuase there is a lot of information. If it was a deauth situation, you will see something like "client being conatined by XXX".If you have a sniffer or you can turn one of the APs at the remote site into a sniffer and use wireshark ...

Thanks George! I'm gathering syslogs at the moment. This is what I'm seeing:
Jan 24 10:44:23 spam_lrad.c:2705 LWAPP-3-RX_ERR9: Received a bad sequenced RRM data request message from AP 00:13:80:94:9c:d0
Jan 24 10:44:24 spam_lrad.c:2705 LWAPP-3-RX_ERR9: Received a bad sequenced RRM data request message from AP 00:13:80:94:9c:d0

I'll also look into sniffing the traffic to get a bit more. I appreciate your response.
