<div>
Hello,<br><br>Select the driver that is with the warning, right click and then update driver, once update the driver, validate if the vm has the same problem with the gateway.<br><br>Additional validates that you have enabled the services integrated in the vm. <br><br>Wan Miniport is a driver that allows the connection of alternative methods in Windows, such as Point-to-Point Protocols over Ethernet (PPPoE) and wireless WAN networks.
</div>


<div>
At the level of virtual adapter, do you have any advanced features enabled at the adapter level in hyper-v ?. Check the vm configuration on the virtual hardware
</div>


<div>
I reinstalled the driver for the WAN Miniport(IP). &nbsp;The Bang went away but still no connection. &nbsp;I opened an elevated command prompt and ran <br />
netsh winsock reset. &nbsp;Still, after the restart, there is still no network connection.

Here are the settings I have on the virtual switch<br />

<div>
validate the DNS of the virtual machine, also execute an ipconfig / flushdns and validate the connection of the vm again
</div>


<div>
1) Stopping the VM, <br />
&nbsp;2) removing the Network adapter, <br />
&nbsp;3) re-adding the network adapter and connecting to the virtual switch.<br />
&nbsp;4) starting the VM

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
