I've set up a jellyfin server on a Windows desktop machine (yeah I know, not the best option). I think hardware server side is more than sufficient with i7 4790 3.6ghz, 3060ti, 32gb ram. For client I'm using Xbox One x with jellyfin client. The server is currently connected via WiFi. I'm getting playback stuttering after about 20 min or so of playback. I'm hoping to get some guidance for transcoding settings and general setup help.
I don't think it's simply wifi causing the issue as the playback bar on Xbox shows the video is buffered for several minutes ahead of playback location.
I use a VPN but you might look into portmaster and their spn. Its a little slow but even using portmaster without the spn you can filter your traffic and simply deny most apps access to the internet
