Ubuntu install wired network driver
Since at the installation at I chose to use wireless network, seems Ubuntu did not install driver for my wired network card.
Here I would like to introduce a simplest way to install some general wired network card driver, just by:
sudo apt-get install linux-firmware-nonfree
I assume this package could tackle with some other hardware problems.
