'ls /sys/class/net' to see all known network devices.
'ip link' to see their states: up/down, (no)carrier, PtP/broadast, et alia
If eth0 is there and appears to be a broadcast medium with carrier present,
you can manually bring it up and verify connectivity:
-----
ip link set dev eth0 up
ip addr add 192.168.0.2/24 dev eth0
ip route add default via 192.168.0.1
ping 8.8.8.8
-----
If it works, then the immutable bit in my previous message should aim your
20mm cannon on the guilty culprit.
