This question already has an answer here:

I recently installed Ubuntu 14.04 on a new, clean, Lenovo i5 Skylake Laptop.

The built in wifi adapter doesn't seem to be working. I used an Edimax stick, which was identified instantly, to access the web. Tried updating, upgrading, nada.

Any ideas?

lev@PC:~$ lspci -nn | grep -i net

  • Please, open a terminal window (Ctrl-Alt-T) then run the command lspci -nn | grep -i net, copy any text it shows, then paste it in your question. – Eric Carvalho Dec 23 '15 at 15:39

I followed this: Qualcomm Atheros Device [168c:0042] (rev 30) Wi-Fi driver installation

Specifically the post by Jeremy31 that starts with:

You do not need Windows drivers and ndiswrapper

This has been recently fixed upstream, follow the instructions to install the backported modules and needed firmware

Worked like a charm. :) Thank you!
