I'll give this a shot when I get home.

The AP is setup really simply.  No wireless encryption, DHCP enabled 
(for LAN parties). I use a static IP on this server because I port 
forward SSH to it from the wireless router.

I mentioned in the previous reply that XP does work on that box just 
fine. (If you didn't see it, don't worry about it, it didn't make sense 
to me after I re-read it.)

dmesg does show that the wireless card is there and that it gets a 
proper association (exact message I'm unsure and am at the office now) 
but that there are repeated messages of 'wireless link not ready'.

SELinux has been disabled on this box since the initial FC6 install.

This is what has me confused.  Nothing is complicated about this setup. 
  It's been in the same place and the same OS for 5 months without 
trouble until now.  And now, for some reason it gets all bollocksed up.

I will mention that when I reboot, and I look in 'Network' in GNOME, 
that I see 2 wireless cards listed.  Originally, it showed 'wlan0' and 
'wlan0.bak', along with 'eth0' and 'eth0.bak'.  I don't know how that 
happened, but I'm wondering if kudzu doing something.  Even when I 
deleted the wlan0.bak option and rebooted, same thing.
