What TCP congestion control do you guys find works the best in Windows 11?

Considering our latency to most of the world most cases bbr2 will definitely assist with speeds but could cause other issues.

To check on Windows 11 run Powershell as admin.

Then run

Code:
Get-NetTCPSetting | Select SettingName, CongestionProvider

That will give you the current setting. Usually cubic or NewReno.

To change this run the commands below.

Code:
netsh int tcp set supplemental Template=Internet CongestionProvider=bbr2
netsh int tcp set supplemental Template=Datacenter CongestionProvider=bbr2
netsh int tcp set supplemental Template=Compat CongestionProvider=bbr2
netsh int tcp set supplemental Template=DatacenterCustom CongestionProvider=bbr2
netsh int tcp set supplemental Template=InternetCustom CongestionProvider=bbr2

Change the value after = to the congestion provider you want to use bbr2 or NewReno or cubic
 
If you're on Windows 11 and want faster internet, consider switching TCP congestion control to bbr2. It will improve speed.
