I followed the following guide looking for a way to solve at last an issue I have been having in 17.10 (Worked in 17.04 but I can't confirm if it did all the time).
The issue can be found in https://ubuntuforums.org/showthread.php?t=2356217 but basically, the Intel ethernet card, suddenly stopped connecting. It simply does not detect an ethernet connection established.
I have physically tried connecting several LAN RJ45 cables to it (Changing between 4 that I know work because they work in other computers at home). I also tried testing it between my computer and an Asus RT5300 and an Asus AC-68U. Currently it is connected directly to a Netgear Orbi (The router) and it does not work (I tried another computer to the same port in the Orbi and it works perfect).
Dmesg mentions the following about the card:

LSHW shows the following:
ModInfo gave me version 3.2.6-K
Trying to compile the same drivers, following the guide above gave me this (after editing the nvm.c file as mentioned in the guide):
My computer is the following:
The motherboard is the Asus ROG-Maximus VIII Hero Alpha with the latest 3703 firmware update.
I have literally tried a lot of things over the past months with no luck, including the recommendations mentioned here Ethernet adapter was disable on Ubuntu 17.04
