Sonos Surrounds not Connecting even after multiple restarts of the Beam, Surrounds and the Router

This is honestly occurring to me so often that I’m kind of put off by the sonos “all things wireless” system.

I have two Sonos Surrounds and 1 Sonos Beam, all wireless.

Every so often the system loses the surrounds and they either show in the app as +?+? as surrounds and no sound playing or are showing as if everything is good but no sound playing.

Today they just refuse to connect no matter how many times I reset the system.

Things I tried:

Rebooted the Beam and both surrounds
Reboot the router
Turned off the router, turned off all sonos, turned on the router, waited 5 minutes, turned on the sonos products.
Removed the surrounds from the app, factory reset the surrounds, reconnected them to the network.
I moved the 2.4Ghz Channel from 6 to 11.

Now the surrounds don’t even show up in the app. Also during the setup, it was taking a long time and it was saying at the end that they are connected but they might not show up in the app and I need to restart the surrounds. I DID, MANY TIMES.

I submitted a diagnostics: 584945453.

Please Sonos, fix your products.

I see tens of threads with this issue. No, there’s no WIFI interference at my house. These surrounds are literally 3 feet away from the router and I don’t have that many devices connected to my router. No neighbors around either.

Here are the surrounds in my router’s device list.

It looks like you rebooted your router, then rebooted your speakers afterward. The Sonos devices need to be unplugged while you reboot the router, otherwise you’re not getting all the potential benefits.

But I’m not convinced that’s the issue you’re experiencing, so doing that step, while not onerous, may not help. However, it wouldn’t hurt, either.

What kind of wifi system do you use? What router is it? Is the Beam wired directly to the router, or do you have it hanging off your wifi? Have you read through the the wifi interference FAQ?

The surrounds are actually should be connected to the Beam itself, using a dedicated 5Ghz signal. Which means the wifi/radio in the controller has to be “on” for all three devices. The surrounds don’t actually connect to your 2.4Ghz signal, I suspect your router is seeing them as attached to the Beam, which is connecting on a 2.4Ghz signal….but perhaps looking at that diagnostic will help Sonos identify what may be going on.

@Airgetlam, Yes. I did that. In OP I mentioned I “rebooted” the router but I meant that I unplugged it.

Really, I tried like 10 different combinations and my router has been restarted like 10 times today. Super frustrating.

I’m not sure what you mean by the surrounds connecting to the Beam. The surrounds can be used without the beam so I don’t see how they piggy back off it without being connected to the router. Are you sure about that?

I’m using the Sonos One (or IKEA Symfonisk) as surrounds. As far as I know, they have their own dedicated connection to the my network.All 3 devices are wireless. The Beam is connected directly to my Xbox via optical audio.

Router is a BGW320-500. It’s the brand new Wifi 6 fiber router from AT&T. (please don’t blame the router).

I read the interference article.

I moved the 2.4Ghz WiFi Channel from 6 to 11.

Are you able to connect a Sonos speaker (not a surround speaker) directly to the router with an ethernet cable?

@GuitarSuperstar just to diagnose or permanently? I can, but I prefer the Beam to be wireless.

Either. I have one Sonos speaker wired to my router and my 10 Sonos products work almost flawlessly including my surround speakers connected to my Arc. If you don’t want to wire a speaker to you router, you could consider getting a Sonos Boost.

@GuitarSuperstar , appreciate the suggestion but all 3 devices including the router are in the same room. There’s no need for a booster, brother.

A wired setup or a Boost could greatly improve the performance of all of your Sonos speakers… but you do you, brother.

@GuitarSuperstar,

Sorry dude. As as said, thanks for your suggestion.

You are suggesting something that’s not solving the issue. Asking me to use my product wired instead of wireless is not a solution, it’s a workaround.

As far as I know, Sonos is not recommending one method over the other so I’ll wait on someone from their team to look over the diagnostics I uploaded.

I’m a power user, I know a thing or two about how this works.

Airgetlam

However, doing such a test would be informative to help those of us without access to your system, or a diagnostic report that might help us narrow down what is happening.

If your surrounds can be used without using the Beam, they’re not set up as surrounds, they’re set up as a second room, and you have the two rooms ‘grouped’. When they are set up as their own room, they do indeed connect to your router. When they’re set up as surrounds, the appear as part of the Beam’s room as +LS and +RS.

Since you’re a power user, it’s liable that you would be better served by getting directly in touch with Sonos support, rather than relying on the community to try to assist you. I would call Sonos Support to discuss your diagnostic.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

Hi @LiveAndDream,

I’ve taken a look at your diagnostic and I can make the following observations:

When attempting to bond surrounds, the Beam attempts to establish a direct 5GHz connection to your surrounds.
When the Beam tries to make this connection, it asks your router for multiple IP addresses - 1 for itself and 1 for each of the surrounds.
Your router sees the Beam asking for 3 IPs and denies the request, instead assigning the surrounds 0.0.0.0, causing them to drop from the network, thus causing the failure in adding them to the Beam.
To make this clearer, here’s the line we see in response to the DHCP request:
```
 br proxy dhcp: DIS 0x80b0213e [REDACTED MAC] 0.0.0.0
```

You should consider wiring the Beam to the network, as others have already pointed out, and attempt to add them again. If this is successful, you can try removing the Ethernet cable and see whether that configuration sticks.
