Drastic action - Reset and go back to S1 App - Hints/tips appreciated

Ever since the 2024 update I have had issues with my Sonos system, but not a big enough problem to warrant taking drastic action. But the inability of the system to play a nice selection of Christmas music over the holidays has even had my wife saying the Sonos is a waste of time and money.

Hence, it’s time to do something about it.

I have had a good read at the comments about “downgrading from S2 to S1. These articles do appear to be, in some cases nearly 12 months old.

May I ask if it would be possible for someone to verify my understanding of what is required to “drop” back to the original S1 app functionality. All my devices are S1 compatible as they are typically 5+ years old.

All I want is my system to respond as it used to do, play the music I want and not drop speakers for days on end, only to then magically find the speaker again and play some random music.

My understanding is: -

  1. Download the original S1 app to another device to avoid confusion. Not sure if there is a particular version of theS1 App to use.
  2. Ensure the S2 app is up to date OR should I fully delete the S2 app from my mobile & tablet.
  3. Delete any windows PC-based apps/tools for Sonos.
  4. Unplug all Sonos devices from the mains power.
  5. Select one Sonos device and power it up, ensuring the Play & Pause buttons are pressed. Allow it to reset itself and wait until the green light appears.
  6. Now using the S1 app downgrade the device to S1.
  7. Unplug the downgraded device and repeat with next device, Key question, do I do this with all my devices so they are at S1? before moving to the next item (h).
  8. Add units one by one until they are being managed by the S1 app.
  9. Hope and pray its all working again!!

 

Many thanks

​@buzz 

I appreciate your time and assistance in this matter.

I started the initial post as I haven't got a clue with network configurations. So guidance has been a massive help to me. 

I will keep on working my way through the various options given by all posters and let you have my findings.

Kept in mind the enablr wifi toggle is horribly mislabeled. It disables wifi, sub, surround and Sonosnet, not just wifi.

Does this mean, if you had everything hard wired you should turn the wifi toggle off on everthing bar your beam and surrounds?

Sort of, Sonos doesn't recommend wiring the Sub or Surrounds as the wired connection is slower than the (confusingly also called Sonosnet) private 5 gHz dedicated network Sonos creates for that task. There is discussion of that around here somewhere.

Been a while for me but working with folks here and at support resulted in me pulling the Ethernet connections to all but primary speakers. It improved my situation and eventually led me to my current wifi only setup.

Many thanks for the time you have given me with this matter.

I will keep working my way through the options and see what happens.

Is this the “holly Grail” of connectivity and low noise:-

or am I getting delusional?

There’s certainly less interference around the devices compared to the two previous matrices posted.

But is the system functioning for you?

So far…...but I am not aware I have made any changes that would result in such a “clean” matrix.

Perhaps a neighbor is interfering intermittently.

The first two matrix displays show 8, but the last shows 9 devices.

There are still 8 devices.

The additional column is the surrounds connection to the Beam. An undefined column will show when the TV is on.
