I bought the Lenovo ThinkPad E580 without operating system and I am trying to install Ubuntu 16.04. Everything is working so far, except the WIFI is not. The strange thing is, that the internet is working when I plug in a LAN cable.
I think a wireless driver must be missing, but I can't figure out, which one I have to install. At the website of Lenovo it says that the Laptop should have the wireless adapter "Intel Dual Band Wireless 3165 AC". But I cant find that one.
