networking - Wireless disabled by hardware switch on an Asus X550V

I'm using Ubuntu 13.04 and I have ASUS X550V laptop. This is my rfkill list:

0: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
3: hci0: Bluetooth

    Soft blocked: no
    Hard blocked: no

Before you start going: Hey, just turn on your hardware switch, dummy... my hardware switch is Fn + F2 and it works perfectly fine on my Windows boot.
But, on my Ubuntu boot it does nothing... All the other Fn + F_ combos work (turn off the touchpad, screen turn off, screen brightness, sound) and they give some kind of visual indicator when I press it.

My lshw log:

*-network DISABLED

Is the module asus_nb_wmi loaded? Check:

lsmod | grep asus

If so, please try a driver parameter:

sudo -i
echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf
exit

Reboot and see if the Fn+F2 behavior is changed.

If the above does not work, redo it again but replace asus_nb_wmi wapf=0 with asus_nb_wmi wapf=1, and if that does not work, replace it with asus_nb_wmi wapf=4 instead.
