We have a Sonos setup that is split across two buildings. One building houses audio and networking equipment and building 2 is where the sonos speakers are playing. We have issues where the Sonos Connect sometimes isn't found and doesn't show up on the network. We use the Sonos connect for line-in functionality.
Based on the research I've done, it looks like I might need to disable the wireless on the Connect and/or replace my switch with one that supports STP.
I've attached a diagram for reference, just wanted to get some input before I purchase hardware.
