Hi guys,

I need serious help after replacing my 3  extreme for 6x TP-Link DECO M5

impossible to get any music through the DECO M5

here's my original setup

4x Sonos AMP:CONNECT

3x AirPort Extreme (tower version)

never connected any CAT5 to any of my 4x AMP:CONNECT

all music was perfectly streamed only over wifi form any od all my  devices without any issues for years

I decide to replace the 3x older Airport for 6x DECO M5

1x DECO is acting as a router & I have connected a network switch for network port expansion, NAS, iMac....

the only difference is my new wifi system (much better over my 6000sq/ft)

but now after totally reset my 4x AMP:CONNECT I still not able to stream anything on it

as a test I decided to reconnect 1x older AirPort Extreme directly to my network switch (who is connected directly to the new DECO). BINGO !!! music is back !!! but I have to create a different wifi network, 1x for DECO, 1x for Airport

Why I can stream through the airport connected the the new DECO vis a network switch but impossible if I remove the Airport... I LOST !

and I cannot at any location run a CAT5 to any of my 4X AMP:CONNECT, it has to be only over wifi

Thank you
