I have a CONNECT in LIVINGROOM and a PLAY5 in BASEMENT. PLAY5 always plays cleanly without issue. CONNECT works great if it is the only thing in a GROUP. When LIVINGROOM and BASEMENT are grouped, I get very frequent drop-outs/distortion/recovery in audio in LIVINGROOM/CONNECT. I've tried changing WiFi channels, but no difference. Besides, both the CONNECT and PLAY5 are connected to hard-wired LAN links in my home (versus WiFi). This combination worked fine for years and only started dropping out like this. Does seem like some form of interference but can't think of what's causing it (no new equipment lately). Note that the I also have a REMOTE but do not make much use given the app support on iPhone/iPad which is used far more often.
