I live in a 2-floor house (ground level and 1st floor), which has 500 Mb/s internet connection. I use a TP-link Mesh wifi setup to distribute internet: 3x Deco M9plus (one is the main Deco attached to my modem) + 2x Deco M5.
In my living room (ground level), there are 1x PlayBar + Sub + 2x Play 3 (just in a next room where the main Deco M9plus is). In this living room, there is also a second Deco M9plus using a ethernet backhaul. In the same level, I have another room where there is a Sonos Amp (in this room there is also a Deco M5 using wifi backhaul).
In the 1st floor, there is a Deco M9plus attached with ethernet backhaul where there are 3 rooms (there is a Play 3 in each room; the last room has also a Deco M5, wifi backhaul).
Everywhere in the house, I have at least 200-250 Mb/s wifi speed.
Sonos setup is with wifi (WM).
When I play Tune-In, all the speakers work well except the home cinema PlayBar+Sub+2x Play 3 group (wifi signal is around 300-400 Mb/s here), when it works alone, Tune-In makes breaks (stopping and reconnecting every couple of minutes), Sonos saying the internet connexion is bad (streaming problem). However, if I group one of the Play 3’s in the first floor with my PlayBar+Sub+2x Play 3 group in the living room, Tune-In plays perfectly: no breaks at all !
Could you help me?
