The wifi on my asus x550ca laptop is not working. Ethernet works fine in ubuntu but wifi does not work. Wifi works just fine when I boot up windows 8.1 though. Is there any special driver I have to install?


Copy and paste this command:

echo "options asus_nb_wmi wapf=1" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf

Reboot and wifi should work.

You may have to toggle your fn keys to remove the hard block after rebooting.

Probably yes. Type drivers into the Dash and choose Additional Drivers application. It will show list of proprietary drivers that fits to your hardware. You can choose one for your WiFi card.

  • It says that there is no additional drivers available. What do I do now? – Jacky Jul 23 '14 at 22:30
