I added this to /boot/loader.conf: wlan_xauth_load="YES" After a complete reboot of my system I get this line in /var/log/messages: Sep 6 17:46:47 speedy kernel: ath0: ath_chan_set: unable to reset channel 6 (2437 Mhz, flags 0x490 hal flags 0x150), hal status 12 Not sure if this is something to worry about.
