Hi @Butchie Yost, Thanks for reaching out, and welcome to the community. Sorry to hear about this ongoing issue on your Sonos system and thanks for submitting a diagnostic report of your Sonos system. I’ll ask some questions to check on this issue. 

• What is the status of the lights on your Sonos speakers?
• Does it happen on other device controllers where you have the Sonos App?
• When did it start happening?
• Any changes that were recently made on the Sonos settings on the App or the system?
• Are you using a mesh WiFi system or WiFi extenders with different Wi-Fi network names?
• Have you tried to temporarily hardwire one Sonos speaker to your main router to check if the issue will persist?

Answers to these questions will help us determine what could be causing the issue.

Hi Simon,

When the disconnect occurs, the lights remain a solid white so it’s not obvious that anything isn’t working as it should until I try to play music or switch on the TV. 
when the TV switches on, the Arc still plays sound from the TV but the rear speakers and sub remain silent. 
 

The app is only on my mobile and not on any other devices. 
The issue has been happening since I started using the system but seems to be happening more frequently. I seem to remember it happened once or twice over the first month since I started using it, now it’s weekly with the occurrence happening twice this week. 
 

The only changes to the system would be updates via the app and I’ve moved broadband providers about a month ago although the issue was happening before changing providers. 
 

The new broadband is a mesh network but as well as the main router, there is a second router set up as a node and uses the same WiFi network name. 
I haven’t tried using a hardwired connection to the router as yet and don’t really want to go down this route as it will mean trailing wires across the room.

many thanks.
