I have a iwlwifi card built into my motherboard. I can see the card, though it displays as a ethernet card?
hutber@hutber:~$ lspci -nnk | grep 0280 -A3
00:14.3 Network controller [0280]: Intel Corporation Device [8086:7af0] (rev 11)
DeviceName: Onboard - Ethernet
Subsystem: Intel Corporation Device [8086:0094]
Kernel modules: iwlwifi
However when checking if is working correctly it certainly does complain about the firmware:
hutber@hutber:~$ dmesg | grep iwl

So I then tried to install sudo apt install backport-iwlwifi-dkms but was slapped by the computer dogs for shooting in the dark:
hutber@hutber:~$ sudo apt install backport-iwlwifi-dkms
