I have 30 Sonos components hooked up in this house. Two Playbars, Five Subs, One new Amp, Two Play 3, the rest mainly Sono Ones G1 with one Sono One G2, and a handful of Play 1s. Two boosts.
Main problem is when I switch from Pandora to Apple Music. The devices cut in and out for one to two minutes. Also I’ve noticed that on my downstairs Playbar surround sound when playing music it gets a half second lag after a few songs. This is the only room that has ever played out of sync. Only way to correct is by powering off the room and then bringing it back into the fold.
I looked at my Sonos Matrix and so much of it is RED RED RED.

'Red’ is obviously WiFi interference that's either surrounding the device, or between connections.
Some things you can perhaps consider are...
- Run your system on Sonosnet with one device wired to the main router.
- Set the routers fixed 2.4 GHz non-overlapping WiFi channel to at least 5 channels away from the Sonosnet channel, ensuring both are least-used by neighbours.
- Keep wireless devices at least 3 feet away from each other and objects that might interfere with signals.
- Set all WiFi access points, hubs, extenders etc; to use the same SSID, credentials and channels as the main router.
- Consider wiring Sonos devices to the local network where interference remains high after exhausting all other options.
- Add all Sonos IP addresses to the main routers DHCP Reservation Table.
- Ensure that the 2.4ghz WiFi credentials are not stored in the Sonos App network settings and if using the Sonos Move speaker consider using that connected to the 5ghz band.
- Place other wireless network devices around the home onto the 5ghz band where it's practicable to do so.
- Review the network WiFi channels in use from time to time in case neighbours alter their WiFi settings, which may then introduce interference.
