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 18.104.22.168, Odyssey Client and PEAP-GTC.
Output from a 'debug dot11 all' on the controller reveals this information...

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.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
