Hi @jonesey122.
Thanks for your response and update.
Are you still experiencing the same problem? Upon checking on the diagnostic report, it shows that the surround speakers are not getting a cloud connection, and it doesn’t show that the Arc is wired to the router.
If you are using a local WiFi network with more than one WiFi hub or access point, I would personally recommend that you try to switch your system to SonosNet by wiring just one standalone Sonos device (preferably the Arc) to your primary WiFi hub or router, that begins the WiFi network.
The system also detected interference on Sonos components running on the network, please refer to this article will help you reduce wireless interference around your Sonos products.
If the above advice was followed and the issue persists, please submit a new diagnostic report so I can check the system further and see if there’s anything else causing this issue.
Let us know how it goes and if you have any questions feel free to reach out, we’re always here to help.
