Hi @memav7, thank you for reaching out to us, and welcome to the Sonos community. We appreciate your detailed post describing the issue and all your effort in checking this from your end. Let me help you out with this.

First I'd like to ask questions to isolate the issue so we can create a path towards resolution.

1. What is the light status on your Sonos Beam after the factory reset? Is it flashing green?
2. Have you tried hard wiring your Sonos Beam to your router? What happened?
3. Did you try to reset the Sonos app from your mobile device?
   • In the Sonos app > Settings > App Preference> Reset App

Please submit a diagnostic report from your Sonos system for us to check. Just include the confirmation number in your response so that we can look up the information. Let us know how you get on with the advice above. We'll wait for your reply.

Thanks Rowena!
