Comment 154 for bug 1220146

Thank you all, now I've got it working.... Expecially thanks to #125 procedure... By the way, for my ASUS F550C it wasn't enough:

iwconfig had wlan0 in the list, lshw -c network said DISABLED, ifconfig wlan0 up gave me an rfkill issue, rfkill unblock all/wifi didn't help becuse situation of rfkill list was and kept being

phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes
and such asus wireless stuff totally unblocked

tried even rm /dev/rfkill didn't work (I hope I won't regret for this removing), but I finally found on http://forum.ubuntu-fr.org/viewtopic.php?id=1429631 the solution for me.

with terminal, create a file (or edit if already exists)
 sudo gedit /etc/modprobe.d/asus.conf

and adding/correcting the line
 options asus_nb_wmi wapf=4

that forces the wireless activation (my hardware switch was keyboard dependent, Fn+F2). Now I've got Wireless active, although led is not working properly (but, sincerely, i don't care).

Hope that could help some one
