To be able to have your ethernet connection to work in the last resort before sending in for repairs or others, is to go to Control Panel, click "Network Connections". Once prompted, click on icon that connects to internet, right click it, it will show as "Enable" or "Disable". Maybe your option in that particular ethernet card was set as disabled. Try enable it. There are three types of connections for your computer. One is 1394 connection, other is wireless connection and lastly local area connection (this is most common use for connections to internet if you have router in network).
Best of Luck!
