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

Household wifi, Sonosnet is not suggested unless there are wifi issues.

Support search for Sonosnet, not much there. Not surprising as it is really old technology in v2, v1 is even older.

The first article is interesting, regarding the issue if you want to stream to numerous rooms simultaneously. I stream my music collection in FLAC to 5 rooms from early morning until bedtime, so a good 14hrs a day. Perhaps the “hard wired” option my be beneficial in my circumstances. If they were all “hard wired” I expect I would have to click “disable WiFi” on the speaker connection option within the App.

You can if you want to, but it’s not required. A wired connection is always going to be the most reliable one.

The disable wifi is an option on any Sonosnet capable speaker, enabled only when wired. It only impacts that one speaker. 

Check your data rate to your Sonos when streaming, CD quality isn't very high and well within the capabilities of any modern wifi that isn't seeing severe interference. 

Wired is a good option if wifi is iffy but going from modern wifi to antique Sonosnet is not a good plan. So wire ALL Sonos or suffer the older Sonosnet techs limits.

A search of this community will find numerous posts about connection issues with BT Smart Hub 2 routers.

Do yourself a favour and invest in a better router.

​@Mr. T 

That's a fair comment, I did work in customer services for a massive technology firm. We found that most people only complain when something doesn’t work, hardly a peep out of them when things work perfectly.

 

​@Stanley_4 

Just in the process of digging out LAN cables to see if some/any/or all my problems disappear. On the other hand I may make it worse…..It’s a learning curve, especially for me.

Anyhow, my antique SonosNet still handles Apple Music Lossless with ease. 🤗

Hi guys, I don't want to start an argument, all I want is my Sonos working again.

I thank you all for your input.

​@GMR, I guess this also applies to the BT SmartHub 2:

BT HomeHub 3 compatibility | Sonos

 

Your Beam is hardwired, did you try and change the SonosNet channel?

Change your Sonos system’s wireless channel | Sonos
