If you are new to the Windows Hyper-V virtual machine world, there are a lot of things to learn. However, knowing how to add a network adapter to the Virtual machine is an essential part of running the VMs successfully.

In this article, we show you how to add a network adapter to Windows 10 Hyper-V virtual machines. There are two ways to achieve this, and we have listed both the methods in this article.

How do I add a network adapter in Hyper-V?

1. Add a Virtual Network Adapter from Hyper-V Manager

4. In the new window, from the left pane check if you have Virtual Network Card. You should see something like the New Virtual Switch.

11. Click on Apply to save the changes. Click OK.
12. If you have multiple Virtual Machine, you can add the same new virtual switch to other virtual machines as well.
13. The Hyper-V is capable of sharing network resources with multiple VMs as long as you are running a Cat 5/6 cable on a Gigabit switch to reduce latency.

2. Add network adapter to Windows 10 Hyper-V using PowerShell

How can I remove my Hyper V adapter?

2. From the left pane, click on Network Adapter and then click the Remove button.
3. Click Apply to save the changes.
