I plugged an ethernet cable into my Play 5 gen 2 which moved all other Sonos products to one wifi (wired) client group. Now my other clients which require 2.4 e.g. (Roborock vacuum) can’t connect to 2.4ghz at all. My wireless 2.4 network now has zero clients.
I went the wired route due to drop-off/cut-outs when streaming Amazon and Spotify, which seems to have resolved that problem. I suspect that Sonos wired now controls the 2.4 band, excluding all other devices as I can’t even connect a laptop or phone to 2.4ghz.
How best to resolve this?
BTW - the other issue I found out by research is that Sonos Play 1 speakers manufactured from 2016 on do work with the S2 app, those built earlier cause conflicts/cutting out (apparently memory issues). I had converted from S1 to S2 when I replaced my Play 5 gen 1 speakers. The telephone support got me connected to S2 for all speakers (Play 1 gen 1 2014-2018 versions, sub, playbar) but it did not solve my pre-upgrade cut-out problems.
