A list of wireless connections doesn't appear in Asus k501ux

Question

Please help with wireless (may be drivers or other settings). I have asus k501ux and I have already installed kubuntu 15.10 on it, butit doesn't see any wi-fi network.

No any networks

lspci -nn | grep 0280 shows folowing:

Answer 1

The wireless adapter is blocked by rfkill.

It is an Asus UEFI issue.

This can be fixed by

sudo tee /etc/modprobe.d/asus.conf <<< "options asus_nb_wmi wapf=4"

Reboot after this command and test.

This solution should help. A quirk for this Asus laptop has been added to upstream kernels. It is actually the same fix as this options asus_nb_wmi wapf=4.
