My speed of internet in wsl 2 is very low, with windows version of win 11.

There is no "vEthernet (WSL)" and, There is no “Large Send Offload Version 2 (IPv4)” and “Large Send Offload Version 2 (IPv6)” in the advanced tab of "configure"(https://answers.microsoft.com/en-us/windows/forum/all/low-internet-speed-in-wsl-2/21524829-18be-4611-bb5f-cabccd2cae31), and as you can see in the image below.

Answer 1

Hello,

First of all I would recommend to check if the network adapter drivers have been updated to the latest available by the manufacturer. Then try next actions:

1. Enable related features through DISM command line. From Administrator DOS prompt, run:

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

2. Update the WSL kernel package. From the Linux machine run:

wsl.exe --install

or

wsl.exe --update
