How do I fix this, I already uninstalled Hyper-V. I uninstalled and reinstalled the LAN drivers.

    Hello Nestor.
    Does the problem occur only when the VM is up and running? It could be due to the configuration of the virtual network card.

    Hi Nestor,

    what a NIC do you use?

    In the past I have had similar disconnections and performance problems with some NICs. Back then, disabling VMQ on the host NIC helped:

    Set-NetAdapterVmq -Name "NIC_name" -Enabled $False

    Let me know, if it helped.

    Kind Regards

    Hi Nestor,

    Thanks for your post. Generally speaking, this issue will happen if your virtual switch is shared with the management operating system. You can temporarily remove the Hyper-V virtual switch to remove the Hyper-V virtual ethernet adapter.

    In the work pane, expand Virtual Switches. Right-click the virtual switch that you want to remove and select Remove Virtual Switch. Or, you can select the virtual switch and click Action > Remove Virtual Switch. Click OK when you are prompted to confirm the removal.

    Best Regards,

    Ian Xue
