Resolving dropouts

Hi all,

For too long, I’ve put up with terrible performance from my Sonos system (frequent drop outs, frequently have to restart the iOS app to get it to connect to the system).

I’ve resolved to connect each speaker via Ethernet in the belief the task would be relatively straightforward to implement - just a question of getting an Ethernet cable to each speaker.

I’m starting by trying to understand the Matrix.

  • Many items come up as ‘undefined.’ Is there a way for me to change that so the Matrix is more useful?
  • The bottom left cell is coloured red, which I believe means an active, but poor wireless connection. Yet it’s hardwired via Ethernet. Am I incorrect to think it should be grey?

 

 

For background, I’ve got a Linksys Velop MX5300 router and a couple more of those as nodes. I’ve also got some switches plugged into the MX5300s in order to expand the available network ports.

Thanks very much for any insights you might have!

cheers, Andrew

The Undefined in the left hand column are unfortunately newer Sonos products that no longer provide data for the matrix.

Undefined in the top row can mean the speaker is unplugged/not connected. It can also mean the private connection of Subs/Surrounds with the soundbar.

The Red boxes in the left hand column indicate a high level of wireless interference around the device.

I would take a look at reducing interference around these. Potentially by changing SonosNet channel to see if the levels then drop. Also check your router’s 2.4GHz network is not broadcasting on the same channel as SonosNet. Ideally set your router to either 1,6, or 11.

The Hallway should not be grey. It should be either green/yellow/orange/red re interference levels around it.

Great, thanks for your reply.

 

Is my main idea correct still - if I manage to get an Ethernet cable to each Sonos product that’ll give me the best performance?

The main body of the matrix indicates the signal/communication between speakers. As the majority of connections are Green and a couple Yellow, this shouldn’t be a cause for concern.

What you want to do is focus on trying to reduce the wireless interference being encountered. Wiring all would give best performance but should not be necessary if you can reduce the interference levels.

Thanks Mr T. My googling only shows channel overlap from different wifi networks as the cause of interference.

So I’ll experiment with a different channel for Sonos and see if that helps.

I would also recommend you get in touch with the Sonos technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports in full.

Their insight from looking at any diagnostic is most likely quicker than trying to solve issues yourself through trial and error.

Hmm. Plaster is listed as giving high resistance. 
 

This is the hallway speaker. It probably wins a prize for worst ever located Sonos One.

 

 

Badge +2

What I don’t yet understand is… if I successfully get an Ethernet cable to it, will it then receive and play sound well?
 

i.e. the plaster won’t then stop it receiving data, it’ll just limit the role it plays strengthening in the wider mesh network?

When you talked about the bottom left cell in statement above, I thought you were referring to the Hallway speaker in the matrix?!

The Play:1 in the Hallway is certainly in an interesting orientation.

I also thought this was already wired and you had disabled the WiFi on the device. This is due to the Hallway row in the network matrix not showing any active SonosNet connection, so I’m not entirely sure how it’s playing music if at all if it’s not already wired.

It’s usually at a normal angle and just connects wirelessly.
 

I had to twist it to fit the ethernet cable In the back (poorly designed bracket). For now I’m just running the cable there like that to test for an improvement. If it works I’ll get a different bracket and hide the ethernet cable.

 

Of course, if I leave it that corner, it’s surrounded by plaster so there’s no chance to avoid the interference

Was it wired when you created your initial post with the matrix? If so, then the wired connection is only serving the Play:1. None of your other wireless speakers are connecting through it, as they favour other routes.

Any joy changing SonosNet channel? If you refresh the matrix, are the red boxes still there or have they changed colour?

Yes, when I created that map, that particular speaker was connected via ethernet.

If I manage to connect all the speakers by ethernet (which I think I can), hopefully that means this speaker not being able to connect to others because of high interference doesn’t matter because each speaker will have its own hard wired connection?

I’ve actually seen a big improvement this week, just from disconnecting both my boost units, which has surprised me. I currently have just one speaker connected by ethernet. Perhaps I had something set up wrong with the boosts.

It is recommended to wire back to the Primary node in the mesh setup, not any satellite node.

I can’t see any Boost(s) in your original matrix unless you changed the device name, or were they wired to nodes?

Badge +2

Forgive me, I’ll have to go back a step.

By node, you mean each speaker (or boost) right?

and if one of those nodes is somehow designated the primary node I’m not sure how to decide which is the primary one or how I can hard wire so many speakers to one place

Userlevel 7

By Primary Node, I mean your Linksys Velop MX5300 router (or direct path back to router via a switch) and the node refers to the router’s satellites.

Badge +2

Aha, thanks.

1. So the ideal setup would be a switch connected to my router with sufficient ports to directly connect each speaker with ethernet.

2. Next best thing is each speaker having ethernet connections from my other MX5300s which are in node mode.

3. Best after that is likely a mesh network with each speaker getting little or no interference.

I think I can achieve setup no.2

#2 is not recommended. You should only wire back to the router, not wireless nodes.

As you have a fairly large Sonos system, setting static IP addresses for your Sonos devices is also recommended.

I should perhaps have clarified that the satellite nodes in my MX5300 are connected to the primary node by ethernet rather than wirelessly. Does that improve setup #2?

Yes, having the satellites wired is better.

Is there still high levels of interference when you refresh the matrix? Have you ever seen any improvement? Have you talked with Sonos Support for their insight on how your system performs?
