SonosNet does not activate when it absolutely should.  I have talked to Tech support several times and followed that “converting to a wired setup” instructions procedure a dozen times.  I’ve audio recorded the “click” that I hear when I plug my Ethernet cable into my one plugged in device more times than I can count, just to ask a friend and ensure that I did in fact hear the magical “click” sound.

When I check my setup, a half dozen speakers are in, hooray, “WM: 1”!  If I remove my WiFi network from the app, all those speakers VANISH forever.  It’s like they’ve given up on life and have no will to live.  Even though supposedly there is a magical SonosNet blasting around everywhere.  The only fix is to plug my physical Boost back in, and they magically re-appear!  This Boost must have the magical key that gets them to connect.

The fix for this?  RESETTING my entire system one-by-one.  Tech support told me not to, their forums as well.  But the moment I finished spending 30 hours trying to diagnose the issue, and switched to 2.5 hours resetting my 20 Sonos nodes, BAM it worked!  My Beam became the node that every other speaker connected to.  It’s the most central, newest, and most cable device that I own.  Over SonosNet!  All WM: 0

After a few weeks of fiddling with stuff, I’m back to where I was before.  Half my speakers are green in the status panel and labeled WM: 1.  Sure, my Orbi provides a lot cleaner signal than SonosNet, but I’m really just trying to get my 20 Sonos nodes to not cut. out. every. 10. milliseconds.

Can someone tell me why there is not a more forceful way to disable using home wifi?  I want this prevented and never allowed.  But then when I drop my WiFi, “some” of the speakers get dumb and forget how to connect to SonosNet.  Why do they lose their ability to connect?  I’ve power cycled each and all 20+ times.  Once in a while they work with no rhyme or reason.

What gives?  Why is this so complicated and confusing, even tech support was confused and thought that somehow my router wifi was interfering.  Well guess what, after a full Sonos reset (going against all advice from tech/online) it worked flawlessly right away.  Something is getting into a bad state.

Why did my Beam go from having colored boxes connecting it to every Sonos node to now having no colored boxes in the status table web page?  It was doing exactly what it needed to, being the root node (albeit labeled Secondary for some unknown reason) and connecting to every Sonos node flawlessly.  The system even performed halfway decent!  I was able to stream HDMI audio to every zone pretty much perfectly.  Until other nodes started taking over and then some hopped onto my home WiFi.  Back to total disaster again.  What gives?  Why is there no more advanced configuration when you know the auto negotiation mechanism is failing and making bad choices.

@benn600,
I assume that you have Sonos ‘portable’ devices (Move and/or Roam)??, which are not of course able to use SonosNet, which in turn means that you are therefore not able to remove your WiFi credentials from the Sonos setup. 

I guess your speakers are latching onto the stronger Orbi signal and perhaps it’s because your Boost (presumably wired to the Orbi primary hub) is either suffering from interference and is maybe too close to the router (or it’s wired network connection has intermittent issues) and/or it’s operating on the same 2.4Ghz WiFi channel as your Orbi system, or something else is intermittently interfering with its wireless signal, causing your speakers to then jump over to your Orbi WiFi signal instead. 

That’s my guess as to why you are seeing what you are seeing.

My own thoughts and suggestions are to separate out the 2.4Ghz/5Ghz bands on the Orbi system by giving them different names for their SSID’s (if that’s possible with Orbi?) and put the Sonos portable devices onto its 5Ghz band only and remove the 2.4Ghz Orbi credentials from the Sonos App.

Also try a different Ethernet cable (and try other Ethernet ports) for the Boost wired connection and move the Boost well away from the Orbi and all other wireless products to reduce interference.

Set the (2.4Ghz) SonosNet channel in the App to use the least-used channel and if possible set the Orbi WiFi to use the next least-used ‘fixed’ non-overlapping channel, either 1, 6 or 11, but obviously not the same channel as SonosNet. If the Orbi settings allow, also set the channel-width on that band to 20Mhz only.

Another option to perhaps consider (not recommended, but it’s an option) is putting the portable Sonos products onto a separate Sonos Household and then removing the Orbi WiFi credentials from the main Sonos system - but if you decide to explore this possibility, I would suggest you use separate Sonos controllers for each system, but this really is a very last resort-option if your problems do persist.


Are you using any managed network switches? If so, make sure that they are set for STP, not RSTP.

I think that BOOST has an intermittent network connection either because of a hardware failure or bad cable. Also, don’t connect to an Orbi mesh point, go for the primary.

Is the Orbi or gateway in Bridge mode? One of them should be Bridged.


Has the “WiFi” been disabled on any of the Sonos devices in the controller app’s room settings? This has nothing to do with WiFi; it disables SonosNet.


Thanks all!  I have primarily Sonos One’s plus an Amp, 2 Subs, 1 Beam.  I have 2 Roams and 1 Move.  Yes, these require that my WiFi credentials are added to the “system.”  I can’t separate 2.4 and 5 GHz signals on Orbi.  Orbi is in AP Mode because I ONLY use Orbi for Wifi.  Router, DHCP are handled by a Synology router because it’s the only router with a halfway usable reservations interface.

I don’t use any managed switches, but would switch to them if it would definitely help resolve the issues.

I have disabled wifi on some devices but they’re all currently enabled.  So I have to ask: I have a Beam and Sub both plugged into my main root network switches.  Why can’t the Sub be handled over wired and the Beam then create SonosNet?  This is probably the most meaningful piece of information.  If one single device has WiFi disabled, does that disable SonosNet for the entire system?


I think you were right.  I turned wifi on for every device and restarted every device all at the same time.  When it all came back up, it is using my Beam as the primary device and just about every device is connecting to this.  Odd because I think I did these steps with Sonos tech although I don’t think I unplugged every device after doing so.  They need to all come back up fresh.

BUT it is still using my home wifi.  Maybe I can live with that.  It does seem like devices split out over both networks then, therefore doubling throughput using both 2.4ghz networks.

It’s weird to me how WiFi is essential.  Here are some strategies that I have used previously, some successfully others not:

Run an Ethernet cable between two stereo pair speakers and turned wifi on only for the speaker closest to the primary node.  This one speaker handles the data for both.  Why can’t this one speaker receive the stereo audio file and share it with the other speaker?

Plugged surrounds and Sub into a 5-port Ethernet switch and turned wifi off on 2 of the 3, keeping on only on the speaker closest to the inside.  Again, this one speaker handles all the audio traffic and shares the data with the other surround and sub.

When I plugged Sonos speakers into my Orbi nodes (except the primary node) I would turn WiFi off, so they would get their data either directly over hardwired Ethernet to the main node, or over the 5 GHz backhaul.  But WiFi HAS to be turned off or Orbi starts using this Sonos network as the hop up to the main node.

I have found that home WiFi doesn’t allow for one wireless node to string others, so Ethernet between stereo pair or on a headless switch (surrounds/sub) the secondary devices with WiFi off never show up. When SonosNet is working properly, the other nodes work.  So SonosNet must be operating more like a Bridge than a direct node.

This was appealing because I have an Orbi near these other speakers and I tried to reduce load on the SonosNet as much as possible, therefore resulting in benefiting from my 5 GHz backhaul and the SonosNet 2.4 GHz networks.


In my 22 speaker system I have had to mess with things a bit to get reliable streaming of low-latency live sources (HDMI, etc.) and even music often hasn’t been good.  If I started a song everywhere, it would take 1-20 seconds to start on each speaker.  Splitting the load across different mechanisms has seemed to help, and at times introduced other issues.  I’ve found the Sonos Boost to be a totally useless device.  It’s from 2016 so I think using obsolete technology and processing.

One of my rooms has a stereo pair and the right speaker is about 12 feet closer to the main node, so naturally gets a better signal, so why not handle all talking from this.  Just like my left surround is 12 feet closer than the right surround.  These hop-across configurations only work with SonosNet.  Home wifi just connects to each node individually.


Hi.  Could you please clarify what you mean by ‘it is still using my home wifi’.  Do you mean that some speakers still show as WM=1 in About My System?

SonosNet is not really a separate network.  Once you wire a Sonos device and thus invoke SonosNet. there are two wireless segments to your LAN - WiFi and SonosNet.  Your router (or other DHCP server) still handles IP addressing etc for the whole network.  It is just that data flows between Sonos devices use SonosNet rather than WiFi.

It may be helpful to note that the device from which you initiate a group acts as the ‘group coodinator’.  The more robust the signal to this device, the more stable the group will be, so the choice of first device can be quite significant.

In a stereo pair it is always the left speaker that acts as the co-ordinator for the pair.

If one speaker in a pair is close to a mesh WiFi node and connects that way, and the other speaker connects over SonosNet, instability is likely.


I was just wondering what has happened to the Sonos Boost? It has been mentioned that the Orbi system is set to operate in Bridge mode itself and that all hubs are acting merely as wireless access points to the Synology router, which rightly has its own WiFi switched off, so I was expecting to see the Boost wired to the Synology ‘Router’ and no Sonos products wired to any of the Orbi hubs at all? At least that would have been my chosen setup with the WiFi adapter enabled on all Sonos products.

I would also (for good measure) reserve all the Sonos IP addresses in the Synology’s DHCP Reservation Table.

If there are wired ‘unmanaged’ switches that then are cabled directly back to the Synology router, then I would wire other Sonos products to those switches too (but only if they are wired), such as the main player in a Sonos Home theatre setup (I would never wire it’s surrounds or Sub) and then just leave the portable devices like Move/Roam running on the Orbi WiFi.

So I would not cable anything (Sonos) to the Orbi Hubs at all - that would be my chosen way forward with the setup mentioned.


So I have to ask: I have a Beam and Sub both plugged into my main root network switches.  Why can’t the Sub be handled over wired and the Beam then create SonosNet?

This should be fine.

 

If one single device has WiFi disabled, does that disable SonosNet for the entire system?

No. It disables the radio on that specific device. If it’s the sole wired device then SonosNet won’t be established.

 

BUT it is still using my home wifi.  Maybe I can live with that.  It does seem like devices split out over both networks then, therefore doubling throughput using both 2.4ghz networks.

This shouldn’t happen, unless the SonosNet signal is compromised, by distance or interference. Devices should prefer SonosNet over WiFi.

 

Run an Ethernet cable between two stereo pair speakers and turned wifi on only for the speaker closest to the primary node.  This one speaker handles the data for both.  Why can’t this one speaker receive the stereo audio file and share it with the other speaker?

It can. I’ve used this method for years. Of course the speaker with the live radio has to be on SonosNet, not WiFi. WiFi-connected devices have disabled Ethernet ports.

 

When I plugged Sonos speakers into my Orbi nodes (except the primary node) I would turn WiFi off, so they would get their data either directly over hardwired Ethernet to the main node, or over the 5 GHz backhaul.  But WiFi HAS to be turned off or Orbi starts using this Sonos network as the hop up to the main node.

Many mesh WiFis use a form of STP which fights with SonosNet’s own flavour. The result is that the SonosNet wireless can claim priority over the mesh’s wireless backhaul. Bridging via SonosNet would be very slow. Wiring Sonos units to mesh satellites is not recommended.

 

I have found that home WiFi doesn’t allow for one wireless node to string others, so Ethernet between stereo pair or on a headless switch (surrounds/sub) the secondary devices with WiFi off never show up. When SonosNet is working properly, the other nodes work.  So SonosNet must be operating more like a Bridge than a direct node.

This sounds like the point I made above, namely that the Ethernet ports are disabled when a Sonos device connects to WiFi instead of SonosNet.

 

 I’ve found the Sonos Boost to be a totally useless device.  It’s from 2016 so I think using obsolete technology and processing.

It isn’t. Something else is going wrong. 

 

One of my rooms has a stereo pair and the right speaker is about 12 feet closer to the main node, so naturally gets a better signal, so why not handle all talking from this.  Just like my left surround is 12 feet closer than the right surround.  These hop-across configurations only work with SonosNet.  Home wifi just connects to each node individually.

See above.

 

To be honest, I suspect you may have been overthinking things a bit and trying to fight SonosNet. It’s unfortunate that the presence of the Move/Roam necessitates WiFi, and that the Orbi prevents separate band naming, otherwise you could clear the 2.4GHz WiFi from Sonos and avoid devices attempting to connect to WiFi. In your shoes I’d be tempted to wire a couple of 5GHz-only APs to Orbi nodes and run a parallel 5GHz SSID for the Sonos portables.


By disabling some of the SONOS radios you are trying to second guess the SonosNet topology. In my experience this can lead to issues. In my opinion the only case where disabling some radios is productive is when a pile of SONOS units is mounted in a rack. Here, wiring the units to a switch and disabling all but one radio in the pile is helpful.


Apart from situations where a loop would otherwise occur, or a high bandwidth link would be bypassed by SonosNet, about the only other reason to disable the radio would surely be where interference is a factor. The pile of units in a rack could fall under that heading (plus disabling radios also helps reduce heat dissipation). 

For years I’ve disabled the radio on one of a pair, wired to the other -- otherwise wireless -- unit, due to the former’s proximity to a microwave oven. A wired speaker right next to a Zigbee hub also has its radio turned off.


Okay all helpful.

  1. I do have DHCP reservations for every single SONOS device in my Synology router.
  2. I just plugged my Sonos BOOST back in and lone-behold my surround/subwoofer stopped working.  Tech support told me earlier: oh you gotta have WiFi on with every device.  Right now I DO!!  Something is really weird with the logic.  I have found that previously when wifi was off on my Amp, and hopping over to surrounds/sub via the BOOST it failed and no audio came out.  When I reset my whole system and the BEAM was the host device surrounds/sub worked great!  But at the moment I have done what everyone keeps saying: one device hardwired and the rest wireless, I even unplugged the stereo pairs.  Every single unit is not plugged into Ethernet except my Beam and then when I plug Boost in, just that.
  3. I’ve tried so many combinations of things that it gets confusing.  But still when I have everything working and I remove my home wifi network from networks, half my devices vanish forever, until I plug one of the wireless devices into my Ethernet, and then they all come back.  So something is like making a separate network or something.  It seems like SonosNet just gets forgotten.  What I don’t understand is how SonosNet isn’t just like a hidden SSID that every speaker knows, and if home wifi isn’t found, why doesn’t it scan for that SSID?  And why some devices somehow get the lost devices to come back online but others can’t.  There is some magic happening somewhere.

This is why I say SONOS BOOST is a paper weight piece of trash:  Per #2 above.  When I had Amp plugged into an Orbi satellite with wifi turned off, if the hop device to my surrounds is BOOST, silence emits from surrounds and sub.  When the hop device is BEAM, they play fantastically!  I hear audio from all 3!  So BOOST is a paper weight piece of trash.  Both Boost and Beam are plugged into the same network switch and Boost is actually a couple of feet closer to the surrounds/sub.


The Boost shouldn’t talk to the surrounds/Sub. They’d connect to the HT master device, which ought to be the Amp if they’re bonded to it. Stop disabling the radio (“WiFi”) on any HT master; it kills the 5GHz radio that the surrounds/Sub depend upon. 

 

  1. Enable the radios (“WiFi”) on all your devices.
  2. Wire to the Synology router or the Orbi primary node. Do not wire to any Orbi satellite. 

Wireless Surrounds and Sub (whilst playing) each communicate ‘direct’ with their Sonos master HT device over an ad-hoc 5Ghz connection… they do not generally use the Boost, or your WiFi signal, when playing, they’ll only possibly do that when in standby.

Maybe the master HT (5Ghz) wireless adapter is still disabled, or perhaps not working as it should be, or something is interfering with the ad-hoc communication. Are all the HT devices in the same room without anything obvious likely to cause such a wireless communication issue?

(edit: @ratty beat me to it, so sorry for the repetitive post here).


Wireless Surrounds and Sub (whilst playing) each communicate ‘direct’ with their Sonos master HT device over an ad-hoc 5Ghz connection… they do not generally use the Boost, or your WiFi signal, when playing, they’ll only possibly do that when in standby.

Wireless satellites should always connect to the HT master. 5GHz when playing; 2.4GHz when idle.

Only if the radios have been turned off on the HT master will the satellites connect to somewhere else, such as a Boost. This is an incorrect configuration, and the audio in the satellites is likely to fail.


I was wondering if the Amp is perhaps not located in the same physical room as its Surrounds and Sub and perhaps having trouble communicating with them .. that’s assuming their WiFi adapters are not disabled?


The BOOST must not have a 5GHz radio then but the BEAM does, and the BEAM happily sends realtime surround/sub data even though it’s not the master.  I had the Amp wifi turned off (which is paired to surrounds/sub) and it was happily sending data up Orbi’s backhaul to the root switch, then jumping off the BEAM to get to 1 surround, which was sharing data with the other and sub over a 5-port headless switch.

ALL this said, I have everything EXACTLY as you’re telling me now just to see if it actually works.  Every device has wifi on, every device Ethernet unplugged, except one.  I’m seeing some good and some bad results.  I’ll keep messing with it.  If the band is why surrounds/sub connect but don’t play any audio, that answers one question.  Some sonos devices don’t have a 5 GHz radio in them.  Really odd that Sonos doesn’t build any error messages in, stuff just doesn’t work, but I guess from a product standpoint that’s friendlier.


I have a few nodes that are just stuck to my home wifi.  Right now, half my speakers are connecting to the BEAM.  The other half are connecting to home home wifi.  These other half will only connect to BOOST or my home wifi.  I can’t get them to go through BEAM anymore.  These also happen to be the ones that have NEVER been plugged into Ethernet, they are 100% always wireless nodes.  So there is some weird state that they get in where they have some priority to use home wifi / boost OR the main Ethernet device (BEAM).  If I then remove my wifi from my system, those home wifi / boost nodes vanish forever and never come back until I plug boost back in.  Most of what is talked about here makes sense, but some nodes get into a weird state where they prioritize home wifi/boost and they just refuse to connect to SonosNet unless it’s from a boost.


What I wanted was my BEAM to be the central SonosNet node, connect directly to every wireless speaker (it’s very much central, gets a great connection with every wireless node) and then every speaker near Orbi would be plugged in via Ethernet with WiFi disabled so there is no chance of it forming the hop back to the router.  Then about half the traffic would go over Orbi’s 5GHz backhaul and the other half over SonosNet 2.4GHz to totally wireless nodes, therefore splitting the load between both.  This worked great for a while until it quit and now a few speakers are stuck in WM: 1 mode and they latch onto BOOST when plugged in, even when it gives a yellow connection in the status panel but to beam gave a green latency.  So it makes zero sense that it’s choosing the worse connection.  Beam is conveniently the strongest wireless antenna and also automatically in the best location to be great for every node.

I had this for a few days after my full system reset and it all worked great!  Then I honestly don’t know what broke it.  I was maybe messing with something or restarted some devices and then it all messed up.  Maybe I need to reset everything again, it worked great after that.

In the Status Network Matrix, the WM: 1 speakers have an empty box between them and the Beam.  Why is this empty?  It totally shouldn’t be, it’s a very strong connection.  How can I tell a speaker to connect to Beam’s SonosNet?  Just go back to how it was before, it was working great.


The BOOST must not have a 5GHz radio then but the BEAM does, and the BEAM happily sends realtime surround/sub data even though it’s not the master.  I had the Amp wifi turned off (which is paired to surrounds/sub) and it was happily sending data up Orbi’s backhaul to the root switch, then jumping off the BEAM to get to 1 surround, which was sharing data with the other and sub over a 5-port headless switch.

This was a ludicrous arrangement for the Amp’s satellites. Their signal had to transit the Orbi backhaul, then go out over 2.4GHz (not 5GHz) from the Beam. The Beam’s 5GHz is reserved for its own satellites. 

 

Most of what is talked about here makes sense, but some nodes get into a weird state where they prioritize home wifi/boost and they just refuse to connect to SonosNet unless it’s from a boost.

The connecting to the Boost would be perfectly normal, assuming it’s closer than the wired Beam. 

If some wireless Sonos nodes remain stuck on WiFi I’ve suggested a possible reason earlier: the SonosNet signal could be weak. That said, even when SonosNet is adequate nodes will sometimes stick on WiFi. Rebooting them often helps, as does switching the SonosNet channel to alternative frequencies and back again. The final option is to factory reset those specific nodes and re-add them.


Okay how about this one: I turn my Roams/Moves off.  I remove my home wifi from Networks.  And 5 minutes later they’re back on, connected to my home wifi, and in WM: 1.  How does this make sense? I’ve done this 5 times now.


Also: Beam has no sub or surrounds, it has a Sub but it’s connected over Ethernet to the exact same 8-port switch.


It seems like you can’t remove home wifi when the system “thinks” SonosNet isn’t available.  6 of my speakers think SonosNet doesn’t exist while 6 others connect to it just fine.


What I wanted was my BEAM to be the central SonosNet node, connect directly to every wireless speaker (it’s very much central, gets a great connection with every wireless node) and then every speaker near Orbi would be plugged in via Ethernet with WiFi disabled so there is no chance of it forming the hop back to the router. 

I’ve just explained why this approach won’t work for HT master devices. The satellites are left high and dry without a direct connection to the HT master.

 

they latch onto BOOST when plugged in, even when it gives a yellow connection in the status panel but to beam gave a green latency. 

Do you mean the left column colours? You can’t be looking at the connection strengths. A wireless device can’t connect to both the Boost and Beam at the same time. You’d better post a screenshot of the matrix once all the devices are set up as advised.

 

In the Status Network Matrix, the WM: 1 speakers have an empty box between them and the Beam.  Why is this empty? 

Of course it is. There isn’t a SonosNet connection between them.

 

How can I tell a speaker to connect to Beam’s SonosNet?  Just go back to how it was before, it was working great.

We’ve already set out how.

  1. Enable the radios (“WiFi”) on all your devices.
  2. Wire to the Synology router or the Orbi primary node. Do not wire to any Orbi satellite.
