I have seen a similar thread to entitled "Intel 82579M VLAN disabled" however their issue was related to Oracle Virtual Box.

In my case I am operating the latest Intel Drivers and have Hyper V installed but disabled. I have also tested the scenario whereby I have uninstalled Hyper V support and reinstalled the Intel drivers.

It seems that the only scenario that has worked for me is by downgrading back to Windows 7 with the same driver set from Intel.

Has anyone witnessed the same issue with the Intel I218-LM chipset? Any assistance or avenues that I may be able to investigate would be very much appreciated.

Hello J_K_Knight,

Do you mean that the device Intel I218-LM VLAN is automatically disabled in the device manager?

Please update the driver from the following article.

Additionally, please go to Control Panel\All Control Panel Items\Troubleshooting\All Categories and run the Network adapter troubleshooter.

You can use Device Manager to change the power management settings for a network adapter. To disable this setting in Device Manager, expand Network Adapters, right-click the adapter, click Properties, click the Power Management tab, and then clear the Allow the computer to turn off this device to save power check box.
