As I said in my comment #2 there are a lot of missing modules between
kernel 4.4.0-67 and 4.4.0-66 (working). One of this is the wifi module.
Follow the output of requested commands, also the output of "modprobe
iwlwifi" that as I said before failed:

Title:
network connection (wired and wireless) completely broken after
upgrading to 4.4.0-67 kernel - Ubuntu 16.04 64bit
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi,
I did an upgrade of my Ubuntu 16.04 and I installed last available kernel
4.4.0-67-generic.
My wifi won't work anymore (I had to boot with 4.4.0-66-generic that is
working fine).
This is my lspci
