Bluesound and BluOS

I have had similar problems with my bluesound, it seems to help if I uninstall the app and then reinstall it when problems arise.

I subscribe to both Tidal and Qobuz and have never experienced any streaming issues with Qobuz on any of my three Bluesound devices (both wireless and wired).

My first guess would be an issue with your router, but you said you worked with Bluesound.  I assume they would have been able to identify a router issue from your data log.

Are you connected via wi-fi or ethernet?

First thing to check, within your Node app what does it indicate your

WIFI signal level is?

Second, once a proper Mesh WIFI network was added all WIFI levels

increased greatly including the lower level of the home farthest away

from the router.

Skip the inexpensive "expander" tried them and ended up going

with a Mesh network.

Naturally the ^ applies to less than stellar signal strength.

I would be surprised if it's the router or anything to do with the internet connection, bluesound seems to have some problems, and they are hit and miss from unit to unit for some reason.

I have a BlueSound Node 2 and subscribe to both Tidal and Qobuz, (I was a Beta tester for both).  

I have never had any issues.
