Fixing slow download speeds on Windows 11

Published Tags: English, Windows 11, Internet settings.

I had noticed slow download speeds especially when downloading games through Steam or GOG for example. This post was prompted by trying to download "Split Fiction" through the EA App.

Solution was found from Window Auto-Tuning in Windows 11/10; Should you disable it or not?, (Archive link). Next I have written it here as well.

Solution

A setting called "Receive Window Auto-Tuning Level" may be disabled by default. Here is how to check if it is disabled:

  1. Open command prompt as an administrator and type netsh interface tcp show global.
  2. If "Receive Window Auto-Tuning Level" is set to disabled, then use command netsh int tcp set global autotuninglevel=normal.
  3. Restart your program of choice and restart the download.

This worked for me. Hopefully it works for you!
