>Description:

For some reason (which I don't know) my ath0 gets disconnected from the tha
AP from time to time (maybe some idle timeout on the AP). As long as I used
WEP this was no problem, imediately after the disconnect ath0 reconnected:

Sep 30 11:37:39 night-owl /netbsd: ath0: link state changed to DOWN
Sep 30 11:37:39 night-owl /netbsd: ath0: link state changed to UP

Now I switched to using WAP and the reconnects never happen. After a
"link state changed to DOWN" I have to kill and restart wpa_supplicant.
Sometimes it disapears magically - so I can skip the kill step ;-) 

>How-To-Repeat:
Just run wpa_supplicant with an AP that sometimes disassociates you?

>Fix:
n/a
