I ran the command:

ifconfig -a

which gave this output, there is no eth0:

And I ran cat /etc/network/interfaces:

auto lo

iface lo inet loopback

I ran lspci -nn |grep Ethernet:

04:00.0 Ethernet controller [0200]: Atheros Communications AR8152 v1.1 Fast Ethernet [1969:2060] (rev c1)

How would I install ethernet drivers?
