@John_V Did this also happen on the last build of ROCK that you were running or only after B310? Im assuming you are on B310, but perhaps you could post a screen shot of the web page for Rock so we can all see what you have.
From your Profile its hard to know what is on wireless and what is on Wired - could you elaborate please.
What format are you playing predominantly (FLAC 24/96 DSD etc) and how many endpoints are playing at the time this happens. Wifi congestion can occur when others in the house using it etc so timing of when this happens might be relevant too.
is it the endpoint disconnecting or just the remote? What is being used for the remotes, the endpoints and what DACs etc?
Are you using any DSP features like upsampling etc? Are you importing music while this is happening?
The more info you can provide the easier it will be for us to paint a picture of where the issues might be. See what might help us here
