I have a pair of wireless CISCO Aironet 340 LAN adapter (client) and wireless CISCO Aironet 340 AP. Each was running perfectly fine just few days ago along with other wireless products.
However, when I decided to go through an upgrade with the newest firmware update,i.e. changing the AP's firmware version from 10.x to 11.06, the AP just stopped working properly. (NOTE: The client was also upgraded with the newest firmware, and it does not have any problem at all with other type of APs.) In effect, there could not be any link between this AP and 340 client or any other IEEE 802.11 compliant device.
The Logs for this AP during testing has entries as follows:
Info: Station xxxxxxxxx Authenticated.
Warning: Station xxxxxxxxx Failed association,
Too many stations in BSS.
The Warning message baffles me since there wasn't any association created with any client by the AP.
Additional hint is that there were lots of Packet CRC error at the receiving end of this AP.
I would really appreciate any sort of help or suggestion on why and how this error might have happened, and to set up the network correctly.

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.
