Hello everyone I'm new user of Ubuntu.

Today I've installed the Ubuntu 16 on my laptop, whole life I was using windows so I'm totally new to this system.

I was using cable connection but when I unplug the cable I recognize that system does not show any wifi connection...

I tried few solution from this site - neither worked for me and I think that I mess up something by pasting all those solution commands into my terminal...

When I was looking for nvidia drivers In additional driver menu I found something below nvidia driver - there is Unknow: Unknow (I think it might be the problem). I'm lenovo y720 user - all drivers are made only for windows 10. I just want to say something else - when I change the driver of Unknow: unknow in additional drivers for suggested on my cable connection stops working and the wifi doesn't work anyway.

Can anyone help me locate the problem? I would be gratefull :)

@edit lspci -nnk | grep -e 0200 -e 0280 -A3 resault:
