@h888866j Try to run WSLAttachSwitch like this, without using cmd: /mnt/c/Users/August/Download/WSLAttachSwitch.exe "sw2"

I'm running into the same issue. I've tried many different ways running the WSLAttachSwitch.exe program.

I've tried in WSL2, CMD, PowerShell. I've used both /mnt/c and cmd.exe /c methods. They seem to go through, but when I enter 'ip link'

eth1 does not show. (I created a virtual switch in hyper manager before hand)

[asilk27]

I think I solved it. Don't use the hypermanager GUI to create the virtual switch. use PowerShell.

run this command in PS to make it:

New-VMSwitch -Name sw2 -NetAdapterName ethernet

Then in the same PowerShell window, cd to where WSLAttachSwitch.exe is saved and run:

.\WSLAttachSwitch.exe "sw2"

After doing this I see eth1 in wsl2 after running: $ ip link

Cheers!
