Do you mean to check dmesg -a while doing "vmstat -ia | grep ath0"?
I did run "wlandebug +scan", then ifconfig wlan0 up scan and then 
"vmstat -ia | grep ath0".
The only output I got from "vmstat -ia | grep ath0" is:
irq18: ath0        21   0
The second time I ran that last command I got
irq18: ath0        22    0

It is worth mentioning that wifi with this Atheros card works just fine 
on Windows (I am using this wlan when typing this answer on Windows).
There is a button that seems to enable airplane mode, but pressing this 
button does not seem to change anything as far as FreeBSD is concerned. 
Other than that button I can't find any button that enables or disables 
wifi.
