okay so for the last 3 hours I've been trying to fix this I looked at videos I looked at official Microsoft support pages more videos and forums and I came to the conclusion that I hate computers anyways. If anyone can give me information on how to fix this driver i would be oh so happy I'm trying to play Forza Horizon 4 multiplayer it won't let me connect online. When I go to Xbox home or whatever and I go to settings and Network it comes up with. Teredo is unable to qualify and right below it says server connectivity blocked but everything else is fine. I tried to go in to command prompt doing the whole disabling it re enabling it then I try to uninstall the driver and reinstall it from command prompt and now I can't reinstall the driver it's gone im out of ideas I really don't feel like reinstalling Windows just to play Forza Horizon so if anyone give me any information that would be great and i did try. Add legacy hardware
