Hi,
Code:
rfkill

gives
Code:
rfkill: /dev/rfkill kann nicht geöffnet werden: Datei oder Verzeichnis nicht gefunden
rfkill: /dev/rfkill konnte nicht gelesen werden: Ungültiger Dateideskriptor

which propably means
Code:
Can't open RFKILL control device: No such file or directory

any ideas why?
Code:
lspci
02:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)

tberger2 ... you'd get that in english if using 'LANG=C rfkill'.

You're missing CONFIG_RFKILL I expect

Code:
# grep RFKILL /usr/src/linux/.config
CONFIG_RFKILL=m
CONFIG_RFKILL_LEDS=y
CONFIG_RFKILL_INPUT=y
# CONFIG_RFKILL_GPIO is not set

best ... khay
