After searching questions, forums, guides, I could find any solutions that would fit the average Joe…
Being Ubuntu, Linux for humans, I'll ask the question once again, trying to adjust the best answer so that anyone could use it.
I plug a ethernet cable on eth0 and it doesn't appear on the network manager as a connection. I use Ubuntu 14.04
lspci -nn
03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 02)
ifconfig eth0

ifconfig
command)I download the driver from Realtek to my
Desktop
folder from: driver's pageThen I untar the file and open the path to a terminal and install it with:
For me it worked ....
Edited to remove superfluous commands that would cause no action in example, and to add
sudo
usage where appropriate.
