Ok, that happens because your NIC doesn't have connection (link) with your switch/router (end device).
Yes try to reinstall your drivers for your NIC.
You can also try to make connection by soft pressing the Ethernet cable to the side with pins/connectors.
Tried to reinstall the latest drivers, did not make any difference..

I have a Realtek PCIe GBE Family Controller if that makes my problem easier to understand. Something must have happend during one of the password recovery tool attempts.. which means it must be software related, right?

This guy has a similar problem with the same network card: Ethernet keeps disconnecting - TechSpot Forums

However, his solution did not work as I can't find "PHY" listed in properties, only "WOL & Shutdown Link Speed".

Anyone else has a solution i might try?
