I am running a fresh install of 16.04 Desktop 64-bit on a Gigabyte GA-C847N motherboard and the Realtek dual-ethernet card is not detected at all.
sudo lshw -c network shows the wireless interface (an Edmax USB wifi card installed to get online) but nothing else.
I have tried manually installing the drivers with
sudo apt-get install r8168-dkms with no success.
Is there anything else I can try to see if the Ethernet card is actually working or if it might be fried?
Edit: output of
lspci -nnk | grep 0200 -A2 is blank
