WSL2 slow network

“My network in WSL2 is so slow, I am so sad.”
“Hey I know something, why don’t you check the resolv.conf”.
“Oh great jimkelo93, that helped me!”

Yeah, fuck off.
Is the network slow in throughput or is “the network” slow because DNS name resolution is fucking around?

Long story short, here are a few key points.
I don’t care what’s going on with your hobble box, here’s how it works for me.

  • Windows 11 Pro
  • Intel i5 cheap ass processor
  • 16 GB Ram of cheapness
  • SSD from the trash
  • more I could not care less stuff

The question is, why is the NETWORK in WSL2 slow and why the heck is the vEthernet (WSL) adapter not shown in the control panel? I fast forward to the solution, after all this is my personal online notebook and I just want to read the solution in case I need it again.

ipconfig /all shows the god damm nic but not the control panel, so no gui for settings here.


Disable-NetAdapterBinding -Name "vEthernet (WSL)" -ComponentID ms_tcpip6 -IncludeHidden # disable ipv6
Disable-NetAdapterLso -Name "vEthernet (WSL)" -IncludeHidden # Seems to disable the large packet. Didn't tested it since mine was already disabled

Get-NetAdapterBinding -IncludeHidden -Name "vEthernet (WSL)" # Check if ipv6 was disabled
Get-NetAdapterAdvancedProperty -IncludeHidden -Name "vEthernet (WSL)" # Check if large packet was disabled
