Excessive disassociation/reassociation

I'm troubleshooting a problem with excessive disassociations and reassociations even on fixed, immobile wireless clients. The wireless network is lightweight with a 4402-25 controller and upgraded 1200-series APs. My client is an integrated Intel 2200BG wireless NIC with driver version 9.0.3.9, Odyssey Client and PEAP-GTC.

Output from a 'debug dot11 all' on the controller reveals this information...

This type of activity occurs regularly with the client cycling through various APs on the network with varying RSSI and SNR values. Very puzzling! Any ideas what might be happening?

Thanks in advance!

Re: Excessive disassociation/reassociation

Hello,

Were you ever able to figure out what was happening? I am having a similar issue with some ebox's using prismiq drivers on debian. This one has me stumped. Using a WLC 4404-50 and same model AP's

Re: Excessive disassociation/reassociation

We actually did finally figure out the problem with the help of a programmer that Cisco dispatched to the site. It turns out there was a bug in that particular revision of code (3.2.x something) that incorrectly interpreted a certain message coming from Intel clients. An emergency revision of code fixed the issue. Sorry I can't be more specific relative to the exact message but I don't remember much of the detail.
