I have exactly the same problem.
After updating to windows 8.1 the ethernet has stopped working.
It keeps giving the error that "ethernet doesnt have a valid IP configuration"
It is NOT the firewall as I have enabled, disabled etc the firewall and still no connection.
It is NOT the drivers as I have updated the drivers to the latest ones and have also set it to use the realtek driver.
The ethernet adapter is a Realtek PCIe - same as kaasmas above/
Seems like a windows 8.1 issue.
Please someone help with a workaround.
thanks!
