I couldn't get the virtual switch to work with my wifi adapter if my life depended on it. Figured out there was some issue, which I still haven't found the real reason why, that prevented Hyper-V from using the wifi adapter in the virtual switch.
The workaround is to create an Internal virtual switch and then set your wifi adapter to share the connection with the virtual adapter that is created. Take a look:
In Virtual Switch Manager, create an Internal network virtual switch
Open the Properties of your wireless adapter

Click on the Sharing tab and enable “Allow other network users to connect through this computer's Internet connection” and from the drop down menu select the virtual switch you created.
There you have it. Internet for your Windows 8.1 Hyper-V virtual machine through your laptop's wireless adapter.
I’ve been fighting getting this working for about 3 hours, following other posts across the Internet and this was the only one that worked and worked with a beautiful simplicity. Many thanks for sharing this.
This is working fine!
To see network icon in task bar working proper, I had to reboot my virtual machine after recreating Virtual Switch from scratch
I’m trying to do the same in Windows 10 TP but without success. I don’t have Internet on my VM :/
Hi Pablo, sorry I don’t have an answer for you. I haven’t tried Windows 10 yet.
Hi Pablo, sorry I don’t have an answer for you. I haven’t used Windows 10 yet.
I have Windows 10 TP, and worked fine for me.
Rowell, on my Windows 8.1 notebook the Sharing tab on the wifi adapter properties is missing. How do I get it to show up? Thanks!
I Figured it out. I had to disable and enable a different adapter for the tab to show on this. Buggy windows. I still cant connect my VM, even after doing this. On the VM, are you connecting with thw wireless adapter? Or the Ethernet adapter? MY VM does not have a wireless adapter.
