Hi @VincentBxl 

Welcome to the Sonos Community!

Although nothing in your system has changed, it may be that a neighbour has changed their router or reconfigured their network in some way that results in interference with yours. Or, you may have added a (not necessarily WiFi-enabled) device somewhere near the router.

The best way to resolve this is to ask the speakers what they think. Please submit a support diagnostic and reply here with the number given and I’ll see what I can see.

Please note that the forum software may flag your post containing a diagnostic number as spam - it thinks the number is a telephone number. If this happens, don’t worry as I’ll see it and un-flag the post.

Thanks for your answer.

Here is the diagnostic number 526196688

Meanwhile I noticed that google assistant didn’t answer anymore on my Sonos One localised in the bed room.

I made a reset … and I listen to Sonos from 1h without any interruption !

I made the diagnostic after the reset

Is it possible the issue was this Sonos One ?

Thanks a lot

Hi @VincentBxl 

Thanks for the diagnostics.

I think part of the problem you’re having is due to your choice of Group Coordinator. The GC is the Sonos device that is placed in charge of a group - which is to say, it’s the room first selected when creating a group. As music must reach the GC and then be distributed to other rooms from there, the choice of which room to be in charge can be an important one.

However, in looking to find the best room to be in charge of the group, it seems all the speakers have a fairly high signal strength, while also having a fairly high transmission error rate. I think, therefore, that you must have a device situated near your router that is interfering with it. Please isolate your router from other devices by at least 1m.

If this doesn’t help, then I recommend trying another connection method. All you’ll need to do is re-enable the WiFi interface on your Beam (Settings » System » Salon TV » Beam » Enable WiFi) and wait about 1 minute. Because the Beam has an ethernet connection, it will then transmit a private WiFi for your other Sonos devices to use. They’ll prefer to use it over your WiFi and jump over to the newly available connection type. As long as the router and the Beam are not too close, it should be fine. With the Beam’s WiFi radio re-enabled, you’ll also have the option of bonding your 2x SLs as surrounds for your Beam, should you wish.

Setting up surround sound with Sonos home theater speakers

Note that with the Beam hard-wired and with it’s radio now on, it will be the best room to put in charge of a group.

I cannot say anything about the state of a speaker prior to a reset, after the reset. I think it more likely that the GC happened to change when you reset that speaker. We do not recommend you ever reset a speaker without being advised to by us, unless selling it. A reboot should have sufficed.

I hope this helps.

Hi Corry P,

I learned a lot of things (GC, reset play one) ! Thanks for that.

 I have 3 devices close my routeur :

• Sonos Beam (wired)
• Network Disk (WD)
• Bridge for the connected lights 

I will move the router first. If it doesn’t work I will re-enable the wifi interface on the Beam

If the Beam is wired, you really should turn on the Wi-Fi on it, otherwise it can’t serve as a hub for a SonosNet signal, or talk to any surround speakers you have.

Hi @VincentBxl 

As the Beam had it’s WiFi disabled, it wasn’t responsible for interference. I presume your WD NAS is ethernet-wired, so that leaves the lights’ bridge as the most likely culprit, though I don’t imagine it broadcasts a lot of data and the failure rate did seem consistent.

Another possible source of interference is metal or glass surfaces in close proximity - radio waves can reflect back at the broadcasting device and interfere. Please also be aware of devices that might be on the other side of a wall, including those belonging to a neighbour.

I hope this helps.

Hi,

Thank you both for your advice, Ì will follow them.

First of all I turned my Beam on wifi enabled, because my NAS is wired, my lights bridge is wired too and I have no neighbours ! 

Have a nice week-end

Vincent

Mod edit: corrected typo - “brain” to “Beam”

Hi @VincentBxl 

Although your light’s bridge is wired, it probably transmits on 2.4GHz and should therefore be at least 1m from your router.

I hope this helps.

Hi @VincentBxl 

Have you had any success?

Your English is very good, by the way - better than many Brits’ 

I’m having the exact same issue! Diagnostic 1904419658

Hi @CharlotteFairbairn 

The advice is very similar to that given above. It looks to me like Bathroom 2 isn’t the best choice of Group Coordinator for your system - in fact, it looks like it might be the worst as it looks physically isolated from the rest of the system. Please test playback with either Dining Room or Living Room being the first room selected in the group (disband the group, select one of the rooms mentioned, then group to it).

Living Room looks like it might be particularly close to the mesh WiFi node - it may help to move the node away from the other devices nearby, 1m minimum.

Finally, you’ll probably get better results by permanently wiring one Sonos product - except for the Sub, Kitchen 2 or Bathroom 2 - to the main mesh WiFi node via ethernet, if you can. If you wire the Arc, make sure to move the mesh node away as previously mentioned.

I hope this helps.

Hi,

sorry for my late answer but I was abroad for my work. I followed your advice and everything works fine !

• The beam is now “GC”
• The beam is “wifi enabled”
• The light’s bridge is 1m far from the router.

Thanks a lot for your help !

Regards

Vincent

Hi @VincentBxl 

Fantastic! Thanks for updating the thread!

No need to apologise!
