Hi I've got a aironet1200 set up in a large house with approx 15 clients that authenticate to a radius server. I am constantly receiving the error "packet to client (MAC address) reached max retries removing the client. The users are being kicked off the system up to 10 times a day. I know this sounds like an RF issue bit previously we had a Belkin access point in the same spot that never had any problems with coverage to the exact same users. Does anyone have any ideas what is causing this or any solution the error message shows up in the system logs up to 100 times a day.
This message indicates that the client is getting dosconnected from the AP. This can happen if there is RF interference in the WLAN area. Check if there are any other sources which emit RF signals try to use a different channel on the AP.
As mentioned previously, something is causing you to lose the signal.
Which antennas are you using?
Assuming that you have already tried other channels (1,6,or 11 only) ...and tried re-orienting the AP. Get and load a copy of netstumbler (it's free) and run a scan to see which channel is the least congested, and to look for other interference (like phones, Bluetooth devices, MWovens, etc).
If the clients that are being dropped are using Intel NICs (i.e., Centrino w/ BG2200), then the first step is to make sure they are all up-to-date with their drivers.
Next make sure the AP1200 is as current as possible (12.3(7)JA2, I think)
Then, according to a/some posts recently, you should set the WPA timeout value up from 100 ... maybe start with a 200 and see what, if any, effect it has.
Intel wireless Nics & Cisco APs seem to have issues ... at least in their earlier releases.

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.

The script should be completely self explanatory.
