[ath9k-devel] Fighting with the driver

[Cedric Sodhi <manday@gmx.net>]

Hello, I had a little trouble with the smtp header, if you have not read
the message, it is again below.

A little update: I managed to enable WIRELESS_EXT, which didn't help
much though. A few of the wpa_supplicant errors are gone, but

SIOCSIFFLAGS: Unknown error 132

remains there, two times. wpa_supplicant wont run. Besides, for some
reason, the interface is always renaming itsself to wlan1.

Thanks
