Public bug reported:

The ath9k module appears to load fine. But I'm unable to see any
wireless networks by scanning and I can't get a dhcp lease.

wlan0     No scan results

I tried broadcasting my ssid and turning off WEP. Same results.

Matching iwconfig wlan0 chan 5 to my router's current channel did not
help.

My wireless router doesn't report any log activity.

The wireless LED on my laptop is on. Fn+F2 appears like it is supposed
to turn this off an on but has no effect.

I successfully connected to this router with this laptop when it had
Vista on it.
