I have a system with 6 Sonos Ones operating around my house, running over a Netgear Orbi mesh network. Recently one of the speakers stopped working, and dropped off the network completely. Both lights on the top of the missing speaker are lit white indicating that it is on the network but it doesn’t show up in the sonos app or on the Orbi app as connected. I suspected an issue with the mesh network and worked through all of those issues to no avail. I have searched through all of the forum postings and not found a solution that works to bring it back. At this point I suspect a hardware problem. Diagnostic #: 1837407629
