It looks like there is some pack= et loss at the wireless layer, resulting in large delays at the IP layer. A= lso, every few days, nothing seems to be able to associate. Restarting the = interface (/etc/rc.d/netif restart wlan0) fixes that but the possible packe= t loss remains. >> >> I notice quite numerous errors in dmesg.

Of course I got the ``ath0: stuck beacon; resetting (bmiss coun= t > 4)`` over and over again.
