This could be because the Ethernet card or cable connection is not working correctly. Here are four troubleshooting steps:
1) Make sure that the Ethernet cable from the Ethernet card to the rest of
the network is connected and seated properly and snugly.
2) Check that there is not a broken connection in the main network cable
itself.
3) Check that cables do not show any physical signs of damage. Ethernet
cables should not be crimped, bent, or squished.
4) Replaced all cables that show excessive wear.
