Hi All,I read all the posts here including “can’t connect again” and none of them are identical to my question or issue. My pair of One SLs work fine in connection with my Play 1 and Sub, until …I turn my TV off (the two SL units always stay turned on as they are on separate electrical outlets/circuits in different parts of the room Whenever the TV is turned back on for any watching, the Playbar and Sub connect just fine but the One SLs never reconnect. Never. The only way to resolve this is for me to completely unplug all devices, let the TV sit one minute without electrical power to it, the turn on the TV then the two One SL units right after. A few minutes later all is synced up and works fine.One might argue that this is an IP address issue or network issue but it’s not. It’s consistent every time. I can sync up all the units just fine if all are unplugged and plugged back in. But once the TV alone is turned off (only the TV), when it’s turned back on the One SLs will not resync. seems like a terrible design and I regret purchasing them. Am I missing something? If there is a way to resolve this I am all ears. thanks so much!

ONE SL - Does not reconnect when TV turned back on

Hi All,

I read all the posts here including “can’t connect again” and none of them are identical to my question or issue.

Whenever the TV is turned back on for any watching, the Playbar and Sub connect just fine but the One SLs never reconnect. Never.

The only way to resolve this is for me to completely unplug all devices, let the TV sit one minute without electrical power to it, the turn on the TV then the two One SL units right after. A few minutes later all is synced up and works fine.

One might argue that this is an IP address issue or network issue but it’s not. It’s consistent every time. I can sync up all the units just fine if all are unplugged and plugged back in. But once the TV alone is turned off (only the TV), when it’s turned back on the One SLs will not resync.

seems like a terrible design and I regret purchasing them. Am I missing something? If there is a way to resolve this I am all ears.

thanks so much!

Those diagnostics are purported to save 10 minutes worth of information. It certainly would make sense to submit one or two, and call Sonos Support directly to discuss it.

@HK2300,

See attached highlighted image - I’m just wondering if you’re ‘perhaps’ using a ‘guest’ WiFi network, in addition to your main WiFi network? If so maybe switch off the guest ‘WiFi’ and see if that resolves your issue.

@HK2300,

Thank you. That’s a wise observation although it’s nomenclature. We do not use a guest WiFi, we just named it that way “Hoku-guest” for anyone who comes over or family staying over. That is actually the 2.4GHz band name. We have a tri-band system with 2.4, 5 and 6e. My wife and I have most of our items secure throughout the home on the 5GHz band, and only use 2.4Ghz for our guests and for Sonos because Sonos is limited and doesn’t work on 5GHz network. I guess it requires 2.4, so it’s set up that way.

Perhaps someone more experienced can answer this: might this be a time for fixed ip addresses? Also: @HK2300 do you have your wifi running on a fixed channel 1, 6 or 11, or is it set to “auto”?

Airgetlam

@nik9669a it never hurts, but it doesn’t feel like this is the answer.

I’d be tempted to temporarily wire the PLAYBAR and see if that makes any difference. But then I’m also wondering about incipient failure in the WiFi system of the PLAYBAR, something that would likely be exposed by a diagnostic and call to Sonos.

The Playbar only uses the 2.4Ghz band - the ‘bonded’ Sub and One SL’s do not use your WiFi signal, but instead they directly connect to the PlayBar over an ‘ad-hoc’ 5Ghz wireless connection. My thoughts were perhaps that the 5Ghz router WiFi band (and the Guest WiFi) might have been interfering with the ‘ad-hoc’ 5Ghz connection, but if there’s no guest WiFi, then there’s less chance of that.. but still we can’t rule it out.

My thoughts are to unbond the surrounds from the Playbar and try swapping their physical location and then bond the surrounds back to the Playbar so that they change place and just see if the same issue then occurs with the speakers. It’s also worth rebooting the Playbar too.

Thanks again All!

I‘ll try some of the ideas above and also reach out to Sonos support soon.

As an update - same thing again happened today. So it appears the “ungroup on autoplay” switch off did not resolve the issue.

I rebooted all devices and everything synced fine. Everything worked great today - all day - even with TV turned off periodically for 15-30 minutes at a time (don’t have exact times).
Then we took a break for Christmas Eve dinner and family time for approx. 3 hours. Only the TV was turned off during this time. All other units remained plugged in and turned on.
When I turned the TV back on after that multi-hour break, sure enough One SLs are not synced. No sound coming out of them. See attached photos from the app.
I followed the app recommendations including turning the One SLs off/on and they eventually synced back up.

The riddle remains - why do the One SLs disconnect themselves from the system ONLY when the TV is turned off for extended hours? Weird.

Thanks again and happy holidays!

I think it is worth setting fixed ip addresses to see if that helps. Something is causing the setup to “lose” those two speakers…

Since the Playbar seems to lose the surrounds after a couple of minutes after the TV has been powered off, could you check if it is still able to play music from another source after, say, a quarter of an hour?

I had that thought yesterday. Can you play just to the Playbar? Can you play just to the Ones?

ratty

I think I’d be looking to see whether the surrounds are still connected at layer 3 by an IP ping, and if that fails then check at layer 2 by poking around in x.x.x.x:1400/status.

If all this seems too geekish then a submitted diagnostic when in the ‘fault’ state would reveal the above, and a whole lot more.
