# Restart the Host Network Service 
Restart-Service -Force -Name hns
# Restart the Windows Subsystem for Linux Manager
Restart-Service LxssManager
# Restart the WSL Network adapter
Restart-NetAdapter -Name "vEthernet (WSL)"

This is works.
Thanks

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

This fixed things for me, Thank you!

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.
