Hyper-V: Error when applying properties for virtual switch changes

Error when creating a virtual switch via a WLAN adapter with Hyper-V.

When trying to create a virtual switch with Hyper-V I got the following nasty error message.

Error applying Virtual Switch Properties changes
Failed while adding virtual Ethernet switch connections.
Failed to connect Ethernet switch port(switch name=” “,port name=”< port id>“,adapter GUID=”{GUID id}’):
The system cannot find the file specified.(0x80070002).

Not only did the creation not work, but after that the network connection was dead.

A reboot or deactivating/activating the network adapter in the settings can help here.

Alternatively, the command “netcfg -d” helps here, which resets the network settings. The command is executed via a Powershell with admin rights. Afterwards, a reboot is due.

The problem at this point is probably due to my system’s wifi adapter, unfortunately, as also described here.

If I select the Ethernet adapter, for example, then it works immediately and without problems. Apparently not every network card gets along with Hyper-V or vice versa. There is no real solution for this. In most cases it might not even be necessary. For normal internet over NAT the “Default Switch” is sufficient. Otherwise, you have to bite the bullet and use a different WLAN adapter if necessary.
