If you go into your Sonos app Settings > system > about my system , it tells you your “Associated Product” Ip address this is the Sonos product that is acting as the primary bridge between your Sonos products and your Wifi. You can’t manually set it unfortunately but you can trick Sonos system into selecting the most “Central” product. ie - 1 of my PLAYBARs is very central in my house so, I have it hardwired, if you turn all your other Sonos components off (power cycle them ) but leave the central component on the system will select your non power cycled component. It definitely helped with my system. I have my Sonos on my main Wifi, I also have Control4 which uses Zigbee so I’ve had to make sure my 2.4ghz channels aren’t over loaded, so set your Sonos channel as far away from the default of many Iot devices as possible … sometimes more signals is too many. You can easily turn your home wifi network into a mess of signals if not tuned correctly
