@gumbedamit there are multiple issues here.
1. when there was a problem with qobuz it was related to the files they were serving to the streaming device that use Roon, jplay or native streamer software. The files were corrupted and they acknowledged the issue is on their side. This, however, has been resolved. At least I haven’t experienced issues in weeks now
2. network issues folks are having. You don’t need to hardwire to main router. A properly set up reliable mesh network will do just fine. I use eero and I never had network issues and it’s been years.
