Hi, I have 15 Sonos speakers in various configurations across several rooms. One of the speakers, a Sonos beam, was connected by ethernet cable direct to the router. This allowed the rest of the system to operate via Sonos mesh. Wi-Fi was disabled on all the remaining speakers. The “My devices” data on my internet hub showed all 15 speakers connected direct to an ethernet port via the beam. The system was operating with the Sonos S1 controller, was completely stable and performed flawlessly across all rooms and configurations. This morning i updated the system to the S2 controller. The download was somewhat clunky and appeared to crash at one point. At no point did the app ask to be connected to either a new or existing system. I now have the S2 controller, but all the speakers apart from the ethernet connected beam are now back on Wi Fi.  This is now causing major issues with missing speakers and continuous drop outs. I am now unable to disable the wi fi setting on any of the speakers. My “devices data”on the internet hub now shows only the beam connected direct with ethernet. I have tried powering the speakers on and off, factory reset and reconnected to system. The speakers will only connect via the internet wi fi. I have rebooted the internet hub but all to no avail. Can anybody help? Many thanks.
