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.
