- Open Hyper-V Manager.
- Click Virtual Switch Manager.
- Select External and click Create Virtual Switch.
- Give it a name (calling mine WifiVirtualSwitch) and choose your External network. Leave the checkbox Allow management operating system to share this network adapter.
- Click OK and Yes.
Once you have done this, you can use this connection during the creation of your new virtual machine to ensure internet connectivity on the server. Which, for SharePoint 2013, I'd say is nothing short of an installation requirement. You can also change the connection for existing machines by doing this:
- Make sure the virtual machine is turned off.
- Click Settings.
- Click Network Adapter.
- In the Virtual Switch drop down box, select your virtual switch (mine is named WifiVirtualSwitch).
- Click OK.
