I am looking for some help with an older Sonos system. It is a simple system with just a Sonos Connect plus a Sonos Connect Amp. All connected to a Fritzbox 7582 and a Synology DS 220+ via ethernet cables and controlled by the Sonos S1 app on Android or Windows 11. The system has always been also connected to the Wi-Fi network.
My “simple” problem is that any system configurations, for example the room configuration, are erased every time the Wi-Fi is disconnected. This in not such a big deal but is simply annoying, especially as far as I remember was not a problem with earlier versions of the app.
From what I have read the solution is to disconnect the Sonos from the Wi-Fi network. This should be simple to do as there is a position in the app for exactly this. But when I do this, it simply switches the Wi-Fi back on after several seconds and tells me I have to check that an ethernet cable is connected.
Apparently according to some internet forums one can send a http command to the Sonos units to switch off the Wi-Fi but although I can find the command, I have not been able to find out how to send such a command to the Sonos unit.
Is there a simple method to solve this very simple problem?
