1 Sonos speaker out of 6 keeps dropping out

My kitchen Sonos One SL which worked for 4 years mostly without issue, has just started losing connection to wifi while the other half of the stereo pair (another Sonos One SL) continues to play. Swapping places, changing rooms, even wired over LAN, the problem continues. At times it breaks the app and the entire room they’re in completely drops from the app. Sonos team on X (Twitter) are gracious, even DM me at all hours, but some of the call center techs are argumentative and give me bad troubleshooting advice about this issue.  BTW I also have a Sonos Ultimate immersive Set (Arc+Sub3+dual Era 300s) that play without issue on the same WiFi. Any suggestions will be greatly appreciated and welcomed. 
Thank you.

iPad mini running iPadOS 13.3.1 does not see the Sonos One at all

iPad Air running iPadOS 18.4 not only sees the speaker it allows me to manipulate the audio through AirPlay 

last update for 4/5:  successfully got stereo pair with sub working. minor adjustments may have helped. Signs point to iOS or Sonos App. Maybe a combination of both. 
thanks to everyone for the help and input

Sorry to hear about your issues with Sonos One SL ☹️. The issue is most likely a failing network interface card (NIC). Unfortunately, there is no path to replace or repair the NIC.

Not to add more bad news; but the upgrade path for the Sonos One SL to an Era 100 is and is not feasible; as you would still need another Era 100 to create a stereo pair. However, if you are willing to forego creating a stereo pair you probably have an upgrade credit to use towards the purchase of an Era 100. The credits usually garner at least 15% discount.

You can also check eBay for a deal on a new, used or refurbished Sonos One SL at this link.

Or, or a replacement refurbished Sonos One? That’s a fair trade in at this point. Keeping them from stereo pairing has extended the connection for the problem speaker for a few minutes longer.

I thought the same thing, so I tested over LAN connected directly into the router, same dropped audio issue persists. How about a replacement refurbished Sonos One? That’s a fair trade in at this point. Keeping them from stereo pairing has extended the connection for the problem speaker for a few minutes longer.

I’ve been testing using the Sonos app for content this whole time. Just started testing over AirPlay directly to the one speaker, to rule out any problems that the app may be introducing.

Eureka! I think I isolated the problem, thank Goodness. Streaming directly from iPad to the Sonos One, and not in stereo mode and it’s been going strong for 18 mins (a record). I might get froggy and connect the Sub 3 if it’s still going for another 30 minutes to try and break it. 

Update: 30 mins and no drops or disconnects. Makes a person think 🤔

This is fascinating, attempted to connect Sub3 from the Arc to our problem child. I got the audio cue of a successful pairing (very muted btw) but the sub is not connected to anything. Several attempts to connect have been unsuccessful. 
 

update: reconnected the Sub back to the living room Arc without issue. Audio cue was as normal.

Hmmm….not to be critical or rain on your parade 😊but I can’t quite understand why streaming in mono would make any difference vs stereo. Unless you saying that you’re not streaming to the speakers  as a stereo pair. However, even then I still believe something else is a foot with the speaker.

But...if it continues to work who am I to argue with the Sonos gods 😁

Stereo pairing seems to break it. Pairing a sub is just unsuccessful with no ill effects to the connection.

Sorry for not being clear, stereo pair (stereo mode wasn’t the correct terminology) Correct, mono with each speaker getting its own stream IMPORTANTLY not from the Sonos app works l. Stereo pairing seems to break it. Pairing a sub is just unsuccessful with no ill effects to the connection.

Obviously our posts crossed 😂

If you removed the sub from the Arc it should have given you the option to move it to another room. If not then it wasn’t successfully removed from the Arc. At the very least it should have appeared in the app as “unassigned”. Although my “gut” still suggests it’s  still a failing NIC. The Sonos One SL needs to communicate with the Sub via its proprietary 5Ghz band.
