I have no wifi driver on 14.04. I discovered by running a live usb of 15.10 that wifi driver iwlwifi 4.2.0-16-generic works. I am wondering if there is a way to install this on 14.04? I have tried the obvious google searches but I'm still new at this and probably not looking in the right places.
I can't update to 15.10 because a program I need to use is not supported.
lspci -nn | grep 0280 gives
