Hyper-V Virutal Switch is killing WiFi
Hello EE, I've got a weird issue when I turned on Hyper-V in Add/Remove Programs,Turn Windows Features On/Off it killed the WiFi on my machine. It for what ever reason placed the WiFi Device in a disabled state, unable to enable. I checked to verify there were no power settings that could be causing this. After doing a little troubleshooting I decided to remove Hyper-V, after Hyper-V was removed WiFi works fine again.

Are you talking during the Creation of VM's?

So what I've discovered is that it's not Hyper-V that killed y WiFi but the Hyper-V Virtual Switch. If i disable the virtual switch WiFi works again, if i enable the virtual switch while WiFi is connected the Virtual Switch attempts to authenticate which disables my WiFi.
Which NIC have you selected in the Virtual Switch?
Using Wi-Fi with Hyper-V takes some work.

Disabling the virtual switch fixes Wi-Fi. Not sure why the virtual switch kills Wi-Fi on host.
Which NIC have you selected in the Virtual Switch?

The Default
I'm not sure what you mean by "The Default".
If you go into the Switch that you set up, what is selected for both Connection type? If it is External network, what is the NIC that is selected for it? Lastly, is "Allow management...." checked or not?

"Anybody read the link I posted?": I didn't. I've still not heard if the WiFi NIC was selected for use in the Virtual Switch.

I've posted a screenshot which hopefully helps clarify what i meant when i said default switch. Also does everyone understand that this happens by simply turning on Hyper-V in Control Panel, Turn Windows Features On\Off. There isn't an option to choose which network adapter, nor can i can change it as the screenshot shows everything is grayed out.

The screenshot makes it clear that it is using the WiFi NIC for the switch.
Create a new Virtual Switch, set it to External, and have it use your wired NIC. Check "Allow management...". Assign that to your VM.

My assumptions here are that you are NOT trying to use the wireless NIC for the VM and that you have a wired NIC that you DO want to use. If you are trying to use the wireless NIC, kevinsheih has offered suggestions for how to deal with that.
In Hyper-V switch manager, you can choose not to use it, or pick a different adapter, or you can select the option "Share with management..." so that the physical computer can use the adapter and the VMs can use it as well.
