Ubuntu 16.04 WIFI is not working on Lenovo Y520

Hi Fellows,

Right after installing dual boot windows+ubuntu on Lenovo Y520, I found wifi was disabled & was not listing any available wifi.

Did some research and figured out that wifi is being blocked, if you are having same problem give the following steps a try. It worked out for me though.

From the terminal:

sudo modprobe -r ideapad-laptop
sudo rfkill unblock all

If this enables wireless, we can blacklist the module in order to make it permanent.

Since we now know that this methods enabled your wireless, let’s make it permanent:

sudo -i
echo "blacklist ideapad-laptop" >> /etc/modprobe.d/blacklist.conf

Hope it will be helpful, leave comments if you have other solution.
