I could not connect my Sonos One and Sonos Beam speakers to the Deco M9 Plus system (ie on the same WI-FI network).
It apparently has to do with both systems running mesh and therefore you have to change from "Router" in the tp-link Deco app to "Access point" under Operating mode.
However, you lose functions such as NAT, parental control and QoS (nothing I intend to use).

After I changed this, I could easily connect my Sonos to the Deco system (and without a cord between the devices) True Wireless :)

I have now also activated Google Home and Google Assistant.

So now I can control the whole home via voice control apps (Google) , lighting (Philip Hue) and music playback (Spotify).

So happy with everything now and have much higher internet speed throughout our house.

Update. It does not seen that I can use RE300 Extender when I use Access Point mode, its seen that you need Router mode, but then my Sonos does not work... Or is it any other way to make Sonos work in Routermode without using a wire between them?
