WiFi not working on Ubuntu 15.10

Question

I have an ASUS K501LX, that has a Wireless-ac 7265. I've just installed Ubuntu 15.10, but I can't enable WiFi. I guess it's because of drivers. I have read many posts and articles about people having the same problems on Ubuntu, but I still can't get it working. I have some drivers on Intel's website but I'm not able to install it. How should I proceed in attempting to install drivers for my wireless card?

Result of rfkill list all

    Hard blocked: no
2: asus-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no

Answer 1

Your wireless is hard blocked:yes which means that the wireless switch or key combination is set to turn the wireless radio off. In the case of a number of Asus laptops, the kernel doesn't correctly recognize key presses, perhaps Fn+F2. Let's try to get the key presses working as expected. Please open a terminal and do:

sudo -i
echo "options asus_nb_wmi wapf=1" > /etc/modprobe.d/asus.conf
exit

Reboot and see if your wireless is working after you manipulate the wireless key combination.

If the above does not work, redo it again but replace asus_nb_wmi wapf=1 with asus_nb_wmi wapf=4, reboot and check again.

Also, you can get later firmware to possibly improve wireless performance. With a working internet connection, please do:

sudo apt-get update
sudo apt-get install git
git clone https://github.com/OpenELEC/iwlwifi-firmware.git
cd iwlwifi-firmware/firmware
sudo cp iwlwifi-7265*  /lib/firmware

Reboot.
