Hi there - I’ve used Sonos for years, first adopter back in the day of controller and control wheel!

i’ve recently moved house to a recently constructed 4 storey town house ( 3 years old) which has a basement cupboard with a rack housing the Cat cabling, switch and the BT fibre modem.  I have a BT Smarthub 2.0 (connected to the WAN and switch).  There are 3 connect Amps in the rack feeding speakers in the kitchen, living room and cinema room (all cabled in ceiling speakers).  I also have a Play1 in a bedroom connected via ethernet to the wall socket which feeds into the switch.  The cinema room has a Playbar and Sub, connecting wirelessly (in the next room in the basement to the rack).  

I have had zero problems with the Playbar, Sub or the Play1 since arriving and changing ownership / router.  The 3 Connect Amps have all dropped off the App or i’ve had “can not connect” messages, or they have played (radio or Spotify) for a minute or 5 mins, and then dropped.  The room then also disappears from the App for a while and sometimes reappears.  

So I have changed from one Connect Amp connected to the switch and then directly to the router by cable.  I have connected all 3 to the switch, i have disabled WiFi on each - still dropping.

It was working better originally and only just disappearing off the App and not dropping whilst playing, but its really annoying and i’m close to thinking its a hardware issue but feels more like networking / IP addresses etc.  I am pretty much out of my depth with the setup on the networking front.

Any help much appreciated!
