Hi EpiphanyDan,

I would suggest you to uninstall and reinstall the Ethernet card on the system. Please enter your service tag # on the link below, select the OS and then download the Ethernet card driver from Network section onto the Desktop screen.

4. Now select properties.
5. In the properties window, under Driver tab, click on Uninstall button.
