Hey @Stuart_W,

Taking a look at your diagnostic, I can see quite a high level of interference between your Dining Room speakers and your Boost. This is likely what’s causing the dropouts. I can see that communication between those units is not the best, dropping around 40% of the packets per minute.

The interference appears to be in the 2.4GHz spectrum, so it’s more likely to be other clashing devices rather than structural or distance related.

The Boost also looks like it’s having trouble communicating with your Conservatory too, but that’s not part of the group.

Let’s try changing the group coordinator of that group of players. Ungroup all of the players, then, go to the rooms tab and select Study, and add the grouped players in from there. Test playback for a while and let me know how things go. 

To my untrained eye your matrix doesn’t look horrible at all. In fact it looks pretty good everywhere, though it is just a snapshot.

EDIT: James is on the case. 

Many thanks.

I tried this and the music cut out part way through the first song. Diagnostic 1251806946

The Dining Room speakers are quite close to the router and Boost - the router and boost being in a cupboard under the stairs and the Play 3s being on a desk just to the left of the door to said cupboard so we’re talking less than 3 yards between Boost and Dining Room with router in between.

I then unplugged the new TV unit to eliminate and tried again but no much different. Playing Study on own seems ok but group with Kitchen and Dining Room and it drops. Now just after I switched off TV unit I noted Dining Room Left had dropped off (red x in app) so re-started that speaker - query speaker fault.

Ran it for 10 minutes on Study only and was fine. Added in Dining Room and again fine for 7 or 8 minutes then added Kitchen and playback stopped after a few minutes - app had message saying Playback interrupted because Wi-Fi unstable.

@James L. 

Any useful pointers in those diagnostics?

Apologies for the delay @Stuart_W,

I can still see the high interference across pretty much all rooms in the group, and the reported issue for the dropout was a buffering error - specifically, that connection dropped between the player and the music source for over 12 seconds. That definitely indicates some form of connection error between the NAS drive and Sonos. I’m limited in the amount of troubleshooting I can perform here, since this isn’t a live platform, so I’d suggest getting in touch with our care team. You can tell them that you’ve been working with me on the Community and they can reach out to me with any questions.
