At home I have installed a Mesh WiFi using 4x TP-LINK Deco M9 stations: 2 at the first floor (incl. the base station), 1 at the second floor and 1 at the third floor. If I run Internet speedtests on various mobile devices in various places of my home I reach approx. 400 Mbps download / 40 Mbps upload / 18 ms ping time. The WiFi provides 2.4 and 5 GHz networks. All devices that are connected to the WiFi (old iPhones, new iPhones, old iPads, new iPads, old Android phones, new Android phones, Apple TV, Chromecast, Smart TV, IoT devices, laptops, Chromebook, etc. etc.) all connect ok and have a good, fast and stable signal. Except my Sonos speakers.
I have a Play:3 and Play:1 at the first floor, Play:1 at the third floor and a One at the fourth floor. I use the new Sonos app on iOS. All firmware of Sonos and Deco devices is up-to-date.
Even if placed within 1 meter of the Deco M9 stations, the Play:3 and Play:1 on the first floor are sometimes sluggish and sometimes give connection errors. Most of the time they work, but for some reason they sometimes have connection errors. I have wired those with network cables to the Deco M9 stations. I don’t like it, but it’s working.
The Play:1 (third floor) and One (fourth floor) or not easily wired to the Deco M9 stations without “home redecoration”. They are connected approx. 25% of the time (and then function properly), but most of the time they are not identified (listed) by the Sonos app and I need to restart the Sonos devices, restart the Sonos app, restart the Deco M9 stations, etc. to get it working (or not). I feel quite frustrated because both Deco M9 and Sonos devices are well rated and the not cheapest systems, and I just want to listen to music without breaking the walls and putting new cables in them.
I have read some forum posts either suggesting to buy a Sonos Boost, which not always seems to be solving this issue. Furthermore, I don’t want to spend more money for something which should work out of the box. Other forum posts are suggesting it is due to a problem in TP-LINK Deco M9. Which seems a bit strange since all my other devices (and guest devices) work on the same WiFi? If it is a legitimate issue with TP-LINK Deco M9, could anyone point me to the (technical) description of the issue so I can file a support ticket with them?
Thanks for the help,
