Can you check that the ethernet cable is detected with
ethtool eth0
It should report something like this:
Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: Symmetric Link partner advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: off Supports Wake-on: g Wake-on: g Link detected: yes
See that the "Link detected" is "yes". Make sure the speed is at least 100Mb/s full duplex. 10Mb/s or half duplex would mean there is likely a problem with the cable.
This week, I recently experienced a problem with a I217-V network card on a HP laptop. It was impossible to stay connected to a ssh server for long. The connection was lost after a few seconds. It turned out it was caused by the power management (Wake on Lan) as configured by the Windows driver. Disabling Wol on Windows solved the problem. The problem suddenly appeared after some update or other on the Windows side or the Linux side somewhere during the last month.
