Looks like I really have broken something.My wifi green light is off, no matter if the ardware switch is on or off. and the FN key+F5 does work, but has no effect on hardware wifi.
I tried rmmod -f ath9k sudo rfkill unblock all sudo modprobe ath9k and since it gave me a FATAL: something like "no athk9 found" sudo modprobe ath9k nohwcrypt which gave me sudo modprobe ath9k nohwcrypt And I can't do rfkill list all anymore. Help much welcomed !
