Windows 10: Hyper-V and WSL2 networks do not communicate

I have this situation:







[COLOR=rgba36, 39, 41, 1]The Host is Windows 10 Pro ver. 20H2[/COLOR]


[COLOR=rgba36, 39, 41, 1]The Host, the Hyper-V VMs and WSL2 all have Internet access; they all can communicate each other, except wsl2 towards the VMs and vice versa the red arrows.[/COLOR]


[COLOR=rgba36, 39, 41, 1]The Hyper-V VMs use the "Default Switch" vNet: 172.29.96.1, netmask: 255.255.240.0, conn type Internal[/COLOR]


[COLOR=rgba36, 39, 41, 1]WSL2 uses "WSL" vNet: 172.23.240.1, netmask: 255.255.240.0, conn type: Internal[/COLOR]


[COLOR=rgba36, 39, 41, 1]There is a third vNet, named "nat", I can see using "ipconfig" but that is not listed in Hyper-V virtual switch manager: 172.25.128.1, netmask 255.255.240.0, conn type: ?[/COLOR]


[COLOR=rgba36, 39, 41, 1]Can anyone help me? Thanks[/COLOR]

Hyper-V networking

Windows 10 Pro, Build 10586.71. Hyper-V installed. All was working well, and then I got a chipset update from Dell. Installed the update and rebooted computer. After that networking was not working correctly, windows showed limited connectivity. I looked
a little to roll back the driver update, but Windows did not show a new Nic card driver and the chipsets I looked at also did not show a current date. The Dell Command update program does not provide a way to uninstall updates.

I tried to access hyper-v switch manager but it returns an error that "an error occurred while trying to retrieve a list of virtual switches". Also tried using the powershell cmdlet but got a general error.

I accessed the networking center and deleted the Hyper V adapter, then edited my LAN card's config disabling the two Hyper V protocols and enabling the rest. This let me get back on-line with my computer. I have tried uninstalling the Hyper V feature,
reboot, reinstall - but I am still unable to access the switch manager. I then removed the feature again, re-named the C:\ProgramData\Microsoft\Windows\Hyper-V directory, rebooted, added the feature again. This time (obviously) none of my VM's show up but
I'm still unable to access the switch manager.

There is no critical data in my Hyper V, I use it for testing, re-creating issues, learning, etc. Is there a way for Windows 10 (or something designed for server 2012 that will apply) that I can use to fully reset the Hyper v networking, or fully rest all
of hyper v so I can get it working again? I do use the workstation heavily, it's my work computer so it would be very difficult to impossible to reinstall the OS.

Thoughts and suggestions appreciated.

Hyper V deativication

Hi Geoffrey,

Hyper-V lets you run an operating system or computer system as a virtual machine on Windows. Before proceeding in disabling
Hyper-V, please create a backup of your files for security purposes.

To disable Hyper-V, please follow the steps below:

• On the Cortana search box, type Turn Windows Features on or off and press
  Enter.
• Look for the Hyper-V folder.
• Uncheck the tick-box next to the main Hyper-V folder and click
  OK.
• Restart your PC.

Should you have further questions, please let us know.
