    Believe it or not I actually have seen this before. To fix I had to roll back the driver. Try the following >
    – Open Device Manager
    – Navigate to the ethernet Adapter
    – Right click on adapter and click Properties.
    – Click the “Driver” tab
    – Click the button to “Roll Back Driver”
    You may be prompted to reboot the computer. If so, please reboot. Let me know if you have any luck with this procedure.
