Restart-NetAdapter -Name "vEthernet (WSL)" cannot be run because vEthernet (WSL) is gone when Restart-Service LxssManager.

But, when I start my windows terminal, then open Ubuntu WSL, I can restart the vEthernet (WSL). Is it common behavior? Because it's like everytime I shutdown the WSL, then the hyper-v adapter is also gone.

This script is working for me, many thanks, I have seen the case where "vEthernet (WSL)" disappears not sure why, if I run "wsl --shutdown" and the adaptor still shows up,

@Rizary Does it help if you restart the adapter before Lxss ?

Restarting eventually fixed it for me - I had to toggle WSL integration on/off for my distro after reboot. Also realizing that toggling on Windows-container mode broke WSL networking again...

I added

wsl --shutdown
wsl ping google.com -c 4

At the end just to check that the wsl internet connection works at the end

Thanks
It's working for me. Is there any permanent solution?
This is very dangerous and annoying.

It didn't work for me.
I had to add a firewall rule to whitelist the Network Interface.

This works :) I initially copy pasted your code directly into PowerShell terminal and it didn't work. Then I created a separate .ps1 file and ran it and then it worked. Thanks!

After 1h30 of trying everything on stackoverflow, this worked ! I am surprised this is still needed and still works after 2 years.

@dtraparic Happy that it help you. I'm also surprised that it's still relevant.
