I just installed Debian 8 on my laptop, Lenovo X230. I am connected via ethernet. However, I am not able to see any wifi, or connect.
I did the following:
In my /etc/apt/sources.list, I added deb http://http.debian.net/debian jessie main contrib non-free
as suggested, did apt-get update, and installed firmware-iwlwifi. However, listing lspci does not show a Network Controller.
Any help will be greatly appreciated.
