As the Move connects to your router, it suggests there is wireless interference which is causing the audio interruptions on the Move.
In the room settings for the Move, you can check the network connection by clicking on the Move > Network
You could also try changing the WiFi channel and/or band the Move is connected to in your router’s settings.
If you submit a diagnostic from the app when you next experience the issue, then contact Sonos Support, they should be able to review the diagnostic to pinpoint the actual cause.
