Can't connect to any Wi-Fi on Asus X550C in Ubuntu 14.04

I did a clean install of Ubuntu 14.04 the first and the only OS on my new laptop ASUS X550C and I cannot connect to any Wi-Fi, even toggling fn+f2 (keyboard default) doesn't swith/show Wi-Fi indicator on.

here are some outputs from my system:

Solution 1:

Please try:

gksudo gedit /etc/modprobe.d/asus.conf

Use nano or kate or leafpad if you don't have the text editor gedit. Add a single line:

options asus-nb-wmi wapf=0

Proofread carefully, save and close the text editor. Reboot and tell us if the wireless is now working. If not, edit the file again and change the factor from 0 to 1 and reboot again. You can also try 4.
