If it doesn’t help, please reproduce the issue then, submit a diagnostic report through the Sonos app, and reply with the confirmation number. I'd start by reviewing your system as well as the status of the devices, it will help in identifying what's possibly causing the issue.

I’m looking forward to assisting you further from here.

Hi @Caluwe.

Thanks for your reply and sorry for the delayed response time.

Upon checking on the diagnostic report, it shows that the WiFi/wireless interface in the Sonos Arc is disabled. In general, disabling your WiFi can be a useful option for Sonos components that don't need to use their wireless connections, like a set of Connects or Connect: Amps that are installed in a rack mount. 

Kindly try to enable the WiFi on Sonos Arc:

• In the Sonos app, tap the Settings tab and select System.
• Tap the name of the room, then tap the model of the speaker under Products.
• From here, you can choose Disable WiFi or Enable WiFi.
• The app will show which is currently selected with a checkmark.

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.

Hello Annazel, This was the solution for me! I had wifi disabled for arc speaker because it is wired connected. thanks for the support!
