Sadly if you're having issues with disconnecting and/or an unstable bitrate....
Then that would indeed be due to a network issue at some level on your end.
You could try changing the servers you're streaming to
Lowering your bitrate to something that runs more stable
Or maybe contact your ISP and have them come out an do packet loss tests on your lines.
Outside of that, I would suggest again going over this guide here as it does a really great job at covering all issues and solutions to things that would cause that issue you're having:
