My Sonos speakers keep dropping out.
Check whether one speaker or grouped playback fails, update Sonos, verify all units are on the intended LAN, and assess 2.4 GHz congestion/multicast and mesh topology.
Affected rooms; wired Sonos units; STP/loops; RSSI; channel width; multicast.
Network specialist for loops/multicast; Sonos for device diagnostics.
Show the technical detail
On a managed Wi-Fi plan
Inspect clients and topology; use Sonos-recommended 20 MHz on 2.4 GHz where configurable and avoid unplanned mixed wired/wireless paths.
On another provider's router
Router controls differ; Sonos app/device support remains Sonos scope.
What to be careful of
Do not factory-reset the whole Sonos system first.
