I've got a problem with my Cisco 1121G AP. I'll post the Config first
and then the log. Long and the short of it is I have 2 computers and a
laptop. Laptop has a Cisco a/b/g wireless card while the two desktops
have Linksys Wireless-G PCI cards. The Cisco card can go forever no
problems, the desktops both have some issue where they get
deauthenticated and ...well see below. It causes havoc when a user
attempts to watch streaming media across the wireless links. Generally
what I have to do is restart the wireless connection and it works for a
time before the same problem pops back up.

Your problem sounds like a bug in the Linksys cards. I'd recommend getting
the latest Linksys firmware, then if this doesn't fix the problem, contact
Linksys tech support.
Either that or replace the Linksys cards with PI21AGs.
