I just did a clean install of Windows 7 on a 19 month old Dell computer. The install went fine except for an annoying network connection issue. When I restart Windows, I lose my Internet connection and when I open the Network and Sharing Center I find an Unidentified Network in addition to my Home Network. The two are connected somehow because if I disable the Unidentified Network, I end up disabling both.
I found a way to fix it during an Internet Search. I get into my LAN properties, then Configure the Realtek PCIe GBE Family Controller, go to Network Address and then change the Value either from Not Present (its original value) to a value (the numbers entered don’t matter) or from Value to Not Present, click OK and the Network reconnects with the “Unidentified Network” gone.
I also have to go through this if I should happen to lose my Internet connection briefly.
Any ideas for a permanent fix to this?
