I have recently installed Ubuntu on a Lenovo Y520. I'm not able to turn on the wifi.

I heard that there are some issues with WiFi in Ubuntu 17.04 but they all are related to connectivity.

I wonder if it could be related to BIOS settings as I had to change a few to install Ubuntu on this machine.

I didn't find any key on the keyboard or any button on the laptop to enable/disable wifi physically.

Wifi is working fine in Windows OS on the same machine. So I don't think it is switched off.

  Please edit your question to add the result of the terminal command: rfkill list all Also, isn't Fn+F7 the combination to turn on airplane mode which turns off the wireless radio?

  Thanks. Yes. I had already turned airplane mode off. I have also copied intel driver to "/lib/firmware". But it didn't work. I'll update the question with rfkill cmd op.

It is a very bad idea to change /etc/network/interfaces . It will disable Network manager. The problem is with rfkill and ideapad_laptop.
