Keeping WiFi devices three feet apart is a good idea. Sonos does offer the option to turn off the internal radio (labeled disable WiFi) that you could use on all but one of the too-close to each other Sonos devices. Getting some distance from non-Sonos devices would be good too.

You do have your Sonos mesh and WiFi on different channels?

Thanks for the response. When I introduce Starlink as the new incoming network I did tweak some of the wireless access points.  Tonight I did have to change back my Sonos network back to a channel that was not on my wifi channel.  I have a unifi setup with two wifi bands, a separate 2.5 and 5.  The 2.5 band has the 1, 6, 11 and the “best practice” is to not repeat those channels nearby.  I have 6 APs with two of them outside.  I used to have only 4 and was recently advised I needed to add at least 2 more given the size of the area we’re covering.  What I did tonight was not use Channel 1 at all on that wifi network and changed sonosnet to channel 1.  Trying this now to see how it goes. 

By wifi devices, would that include all of the Sonos Connect amps?  That may be hard for me to do as many of them are in the same media closet. I’m thinking you probably mean the “other” wifi devices.  There is an apple mini in there that serves as one of the music libraries and it does have wifi turned on. As this worked for 5 years until just recently, I’m hoping the above change with that network may help.  To undo my media closet would be a pain.  

I’ve read different things about disabling the wifi and taken different approaches through the past 5 years.  Currently, I have the wifi on on all of the devices even if connected by ethernet.   To take things in steps, I’ll try that next if the problem continues.  Thanks for bringing that up as an idea as I was waffling on whether I should do that.

With multiple access points and other WiFi devices picking channels is difficult.

The key point to remember is there are only three good options in the US, 2.4 GHz channels 1, 6 and 11, as all the others interfere with one or more of the three good channels.

I’d give Sonos one channel, with no AP or other device on that channel.

Lay out a map of your AP locations and try to get them arranged (using the other two clear channels) so that same-channel distances are maximized.

How big an area are you trying to cover, my Ubiquity APs cover out several hundred feet on 2.4 and at least 100 on 5 GHz.

Connect Amps count. A wired Sonos does not need the radio (aka WiFi) enabled unless it is bonded to Surrounds or a Sub so shutting the radios off in your closet would be a good thing, and only a couple clicks for each device.

If you want to put your Sonos on your WiFi you could do that by removing all Sonos Ethernet connections, otherwise any connected Sonos, with the radio enabled, will create the SonosNet and other Sonos that can use that may prefer it to your WiFi.

Stanley:  Thanks so much for your responses.  It’s funny when I google my Sonos issues and find my posts from a few years ago and you were helping me then too!  Ha!   Seriously, I really appreciate it. 

Taking things in baby steps to see what improved what, I turned off the wifi on the wired devices.  There seems to be conflicting stances on this on the posts I’ve read through the years, but I guess it’s best to turn it off if one has a problem.  Just wanted to report back that I think this baby step helped improve some of the connectivity.  No red.  I see a lot of boxes are just “white” now and I think that means those are the newer devices that don’t show noise.  I could be wrong as I thought they were showing noise when I had wifi turned on.

I’ve been playing music off and on all day and yesterday and so far no issues.  Will keep experimenting.   I may go the 100% wireless route if I have more issues, but I think I’m good for now.  (For others reading this, to recap, the main change was introduce Starlink into the mix.  I had a Unifi environment all along and the only change was adding Starlink and a couple of additional access points. )

I’m not sure how to describe the area I’m trying to cover.  We have a 3 story house (finished attic on top) with a house that’s about 5,500 to 6,000 square feet.  We have a pool, an attached and detached garage, and a basketball court where we’re also trying to get wifi coverage to.  The detached garage has some Sonos speakers and houses the Sonos Connect with some wired speakers going to the court.  

I was on the Ubiquiti boards asking about our layout and those folks pretty consistently told me I didn’t have enough access points so I added one on the top floor and one outside.  Grand total of 2 on the 1st and 2nd floor (at each end basically) and one on the third floor, with two outside pointing in different directions.  Hope that makes sense.   Thank you.

Edit:  Forgot to include updated matrix.

For the stack of SONOS units in the closet I recommend wiring all of them to a switch and disabling the radio on all but one SONOS unit. With Ubiquiti switches, set them for STP, not RSTP.

Thanks for the note.  Unless I’ve overlooked something, every Sonos unit in the closet has been connected by ethernet to the switch (also in the closet) from the very beginning 5 years ago.  What has changed off/on is whether I left wifi on.  I turned them all back to “off” except one of them.  The one I left on is paired to a subwoofer that is not connected by ethernet, so I thought the radio was supposed to stay on.

I'm glad you brought STP up.  I had changed that to STP in the past based on some advice here, but with my recent changes it seems to have reverted back to RSTP.  I’m changing it back to STP.  Thank you!

Yes, the SUB needs a 5G connection.

Colored to white in the matrix is probably because the Sonos Disable WiFi switch turns off the whole radio and with it off it can’t report any data.

Trying to get as much isolation between same-channel APs and SonosNet is going to be your best option. You could get things as good as possible and then consult directly with Sonos support to decide which radios to disable to reduce self-inflicted interference.

And yes, the usual suggestion is to leave all Sonos radios enabled as that makes for the most robust SonosNet mesh and enables surround connections. BUT in limited situations, with too close together Sons the radio off option can solve otherwise unfixable issues.

I think sometimes the folks at the Ubiquity forums suggest more APs than are really needed. Unless you are seeing connection issues with fewer going that route will reduce your same-channel fratricide. :-)

Hello, I’m back.  

I had changed my Sonosnet channel to 1.  Removed channel 1 from my access points and used only 6 and 11.  I also disabled wifi on all of the wired devices except those that were paired with another speaker.  Then the trouble started again.  I tend to listen mostly in the kitchen. Audio started dropping out for 30 seconds (but kept playing on the subwoofer).

So I decided to unplug a few of the ethernet devices as I saw a thread where a guy said Sonos Support told him he had too many wired devices.  So I turned wifi back on for those devices and then removed ethernet.  Didn’t take long for audio to drop again.  So I decided to go 100% wifi and entered my wifi networked, turned wifi back on for all devices, etc.   I played music for about 45 minutes in the kitchen with no problem.  Then, just like that, the audio started dropping out again.  Did it twice in 15 minutes.

I’m stumped.  Had this system fine-tuned for about 4 years with no major issues.  The change was introducing Starlink, adding the UDM in the process.  

Would seem to be odd that the kitchen Connect just happened to go bad during all of this.  Having trouble further diagnosing what to try from here.   Thanks for reading. 

Adding the latest matrix in case that helps.  

@TheRamblinMan,

If not seen already, maybe see if this link will assist you with your Unifi setup and Sonos devices…

https://github.com/IngmarStein/unifi-sonos-doc

Thank you.  Yes, I’ve seen this some time ago and already did this.  My Unifi setup has been up and running for about 4 or 5 years with no issues (after initial tweaks) until I installed Starlink recently.   I’ve done most (possibly all) in this article.  But, I think I’m going to go back through all these settings in that article to make sure nothing triggered in the opposite direction unintentionally with an update or something to be sure.  Thanks again. 

Worst case wait for the glitch and send Sonos a diagnostic and call Support.

Been a long time since I used satellite but it gave me fits.

I went 100% wifi.  Played for about 2 hours with no problem then it happened again.  Also, in another room with a paired stereo pair, the right one keeps dropping. 

Chatting with Sonos after I ran a diagnostic.  They are telling me I need to put all the access points on the same channel.  Of course, I do not believe that is what Ubiquiti or networking in general calls for.  They told me I had 1, 6, 11 in use and they want me to just pick 1 for all of my access points.  Sort of stuck now.

Before, I had put Sonosnet on Channel 1 and used only 6 and 11 on my access points to see if that would work.  It didn’t resolve the issue.  Still chatting with Sonos but they are basically telling me to use only a single channel. 

Sonos doesn’t seem happy with multiple AP channels when using WiFi but as you point out that isn’t great for your WiFi setup with multiple APs.

I’m resisting buying any of the new Sonos WiFi / wired Ethernet only speakers to avoid opening that can of worms. I have wired and SonosNet connected older gear on a single channel and my APs are on the other two and it is going to take a lot to get me to change.

Be a pain but you could put several APs, near your Sonos gear on a single channel with a different SSID than the rest of the APs you could spread across the other two channels just to see if it worked.

If it does you could wire Sonos Beams co-located (but a meter away) with your APs for your Sonos and put the APs on the other two channels. The store still has some and used ones are getting pretty cheap. Do avoid the Bridges though, they are problems waiting to happen.

Just a further update.  Did a long chat with Sonos.  Disconnected two of my access points as they wanted to see the impact on interference/congestion.  I did that.  System stopped playing after about 5 minutes and then resumed.   Now they want me to talk by phone.  I plan to do that later.  

Now I read online that the UDM router I bought (based on recommendations on the Ubiquiti boards about Sonos) doesn’t support STP that I’m told I need for Sonos.  Some saying they could not get UDM to play nicely with Sonos...spent a nice sum buying that router after posing questions.  That stinks.  

I’m currently 100% wireless. 

I’ve wanted a Ubiquity router for years, even bought an X to play with but it was just too much frustration.

Just re-looked them a few months ago when my Gen 1 CloudKey packed it in but again just couldn't see getting one working as I wanted here. Ended up with a Gen 2 CloudKey Plus and a new AP, but stuck with my trusty pfSense router that is much less frustrating for me to use.

Good luck.

When we built this new place a few years ago I relied on the networking guy to pick this equipment.  He recommended Sonos and Unifi stuff.  He then ran for the hills apparently and went out of business so I’ve had to do a deep dive on all this stuff.  A novice but I’m trying. 

I just decided to go back to SonosNet again to see if that helps.  I don’t understand what happens if I don’t set STP on the Unifi switch.  I had it set but then read the UDM router doesn’t support it.  I may just have to live with occasional drops as I can’t get rid of Starlink for now.  Thanks again. 

I think just setting it on the switch ports your Sonos connect through might be enough but I’ve avoided the subject.

I’ve seen suggestions to just hook a dumb switch to the Ubiquity gear and then the Sonos to it.

As a past IT contractor I can confirm cashing a check while at a dead run for the horizon is a key skill.

If you are experiencing a storm there is a buildup of packets. The network speed will slowly decrease. In one network I was seeing the expected near gigabit speeds immediately after startup. After twenty minutes or so I was seeing 9K speeds and complaints of dropped packets. Enabling STP in a managed switch will mitigate this storm.

SONOS supports STP, not RSTP. RSTP is the default for Ubiquiti switches. UDM does not support STP. You must wire SONOS units to a switch that supports STP.

Thanks for the note, Buzz.  Admittedly, I’m a bit bummed at where I find myself because the folks on the Ubiquiti page (on a Sonos related post) told me to get the UDM based on my situation.   My Sonos units are wired to a switch that supports STP.  UDM is a router that I’m told doesn’t support STP.  Not sure if that makes a different.  Probably not.  I’m a novice and on a learning curve.  

I have this Unifi switch and the UDM.  Not sure which Unifi router I can buy to support STP.
