It doesn't, but I'm not sure if it can't connect because of anything related
to this bug. When bringing athn0 up with 'ifconfig athn0 up', this appears in
the dmesg:
athn0: radio is disabled by hardware switch
athn0: unable to reset hardware; reset status 1
My netbook has no physical wireless kill switch, and the wireless LED is
always on. I have tried the Fn+F8 key combination (a combination specific to
my laptop), as well as the rfkill utility in Linux, to no avail. Further
attempts to bring the interface up repeatedly output the above two lines.
