I have an atheros cardbus card made by ubiquiti.  Every once in a
while wpa_supplicant gets in a loop where it negotiates the key, I
very briefly see "completed" with the wpa-psk, CCMP, etc displayed in
wpa_gui.  Before I can blink the wpa_gui says DISCONNECTED and all the
vitals are cleared.  It then repeats the above forever.  The fix is
usually to do a "service wpa_supplicant restart".  Sometimes I need to
take down the ath0 interface and bring it up too.  It feels like a
timing problem where wpa_supplicant just isn't waiting long enough for

BTW. I just spent an hour trying to get the network working with
wpa_supplicant started before the network code.  If I put an "exit 0"
at the start of ifup-wireless then the dhclient never got started,
even though wpa_gui shows the association exists.  Ipv6 is also up, so
the network is usable for that. I have no idea why dhclient didn't get
started.  The only thing I can guess is timing also.  I've returned to
starting wpa_supplicant from the bottom of ifup-wireless and things
are back to normal.

I guess I need to dig up the sources to wpa_supplicant and watch this
run in gdb and see if I can find the reason for the looping error.
Maybe that will shed some light on why starting order of
wpa_supplicant and the network card is so delicate.
