I have thousands of dollars of Sonos equipment throughout my house in 7 or 8 zones. The ones that are not hardwired have disappeared from the app. I am running an Orbi RBR850 router with 3 satellites. Rebooting the Sonos devices and network/router have done nothing to resolve this issue. Updating router firmware did nothing to resolve the issue. No other devices on my network have any issues other than Sonos. Best I can tell, I now have about $2,500 in Sonos equipment that I can’t use because the system can’t find them.
I need help resolving as soon as possible.
