I have a decently large system with 9 rooms. Several of these have stereo setups and there are 2 surround rooms. Products range from Play:1, to One, to Playbar, to symfonisk, to Beam and one Boost.
My question is about best practice/recommendations about how to start the system and handle the app. If I ever pick the “play on all speakers” right away the system freaks out and starts cutting in and out in different rooms randomly. The only way I’ve managed to get things to work decently if I want to play in more than two rooms at once is by starting to play in only one room, and then adding rooms one by one while waiting 20 seconds or so to let the app think before moving forward and adding the next one.
There must be a better way to get things to be snappier? Or is the controller so sensitive that you really need to let it think for that long?
Both beam and boost are wired. The rest is on the Sonos network. My router is a Netgear Nighthawk R9000 which should be plenty to handle the system, as well as very fast fiber. Controller is used from an iPhone X and an iPhone 8.

Wireless is being overstressed somewhere, and the buffering bursts are choking the flow when all the rooms are started together.
The first room in a group contains the Group Coordinator node. This fetches the stream and distributes it to the other members. (With a stereo pair this is usually the left unit, and in a surround setup it’s the main player.)
Optimal use of wireless bandwidth occurs when the Group Coordinator is wired, so endeavour to start the group from the wired Beam and add the rest. You can always tell which room has the GC. It’ll be listed first in the Now Playing room names, and will be the top volume slider when you tap on the master volume control in the app.
If this doesn’t help, either submit a diagnostic and post the number so Sonos Support can take a look at the state of SonosNet, or go to http://IP_address_of_your_Beam:1400/support/review and screenshot the Network Matrix for folks here to peruse. Get the IP address from About My System.
