I have 3 x BE65 devices all hardwired via ethernet to each other. I also have a BE25 in the garage via WIFI.

I have about 50 devices across all access points working fairly well. I've had the setup for about a week. Also had previous TP Link kit over the years, and an engineer. 

My Sonos is constantly skipping or dropping out. I have 5 x Sonos Play:3 devices (with 1 wired to one unit that is connected to the backbone). I also have a playbar + sub + 2 Play:1 rears that are on the same 'theater' setup. I believe the theater setup is on 5Ghz. 

I used to have a Boost but removed it to keep the network and use one of the play:3's as the bridge (reading many articles says it acts like a boost). 

I've tried Sonos channels 1, 6, 11 and sometimes they work seamlessly, but more frequently dropping out. 

All devices have a static address delivered via the DECO DHCP. 

I don't believe that there is a way to set the BW / Channels on the Deco's. Which may be impacting the SonosNet setup. I'm also using the Deco IOT network on 2.4ghz only. 

Are there any suggestions or ways to identify the problems? Are there any features planned to allow more configuration on the WIFI side of the DECO units? Does anyone else have a similar setup and have any issues? 

Thanks,
