Stack: Sony A80J 77’ TV / eArc / Sonos Arc, Sub3, One SL pair (5.1.2)

Streaming: ATV 4k (gen2) and Firetv4kmax devices used with the above display

Router: Is in the same room (10 x 20) as all 5 speakers; it is Wifi 6 and manufactured in the last year or so; it is a “Spectrum Router” that does not broadcast SSIDs for 5g and 2.4g networks separately; only a combined network

I run SonosNet Channel 1, with 1 One SL wired (changing the wireless channel has no effect)

All of the below happen regardless of Streaming device or streaming application being used (Netflix Ultra, HBOMax, Prime, Hulu etc)

----------------------------------------------------------------------------------------------------------------------------------------

The below used to be intermittent; now I’m having to reboot my various speakers, almost daily. Nothing has changed in my set up

1 Wireless set up

1. S2 app never recognizes my “products” (Sub3, One SL pair) it does recognize the Arc
2. After exiting set up (for Sub3 and One SL pair) I get them to show up but they are always in “Living Room 2” (I only have one room and that is “Living Room” where the Arc is)
3. I futz around in the app, and get the surrounds and sub transferred over to “Living Room” eventually

• Why wont the system recognize my Sub3 and Surrounds in the “add products” step and put them in “Living Room”?
• Is SonosNet Channel as my dedicated wifi/net, a more optimal configuration than wireless generally? 

2 Sub3/One SL pair drop audio (mainly when switching inputs, music to tv; sometimes just randomly)

1. Though they still show up as connected in my “Living Room” product read out, the parenthetical read out subsequent to “Living Room”, on the System page 
2. Again, the sub3 and surrounds are still showing up as connect but no audio emanates from them
3. If I turn off the surrounds and sub with the S2 toggle switch, the Arc then starts to play deeper bass and sounds better
4. This is happening daily, now

• Sometimes Trueplay re-tuning solves this, most of the time I have to drop the sub and the surrounds and add them back - then I run into issue #1 above.

3 Dialog and sound duplicates

1. Sound and sound effects, coming from the the Arc bar, are duplicated in the One SL pair, creating a echo effect
2. This is for stereo audio, and 5.1 and Atmos content

I suspect the Router is the issue, even though it is a modern router and is close to all speakers.

What is the best way to go about troubleshooting all of the above without pulling my hair out dealing with a non-technical, frontline CS person, reading off a script?

• Should I factory reset my whole system, losing all that I’ve built out with my music functionality?
• Should I get a different router, if so where is the recommended list from Sonos?
• Or, is there a way to get trained support from knowledgeable folks inside Sonos?
• I was a Beta tester, but those skilled folks can only engage with issues related to the current S2 beta version push (and that is not the case here).
• I disengaged from the S2 beta test, cleared the beta version of the S2 app off my system (phone), to eliminate beta versions of the app as a variable in this.
• The S2 App has never recognized my “products” in correct set up sequence since my first set up, and this is with two different routers.
