Hi I’ve had 2 Sonos Onesfor a few days and am experiencing issues much as described in this thread which is disappointing as its a few years old. Also the same programmer seems responsible for the forum registration screen as after you enter all you info it then says that user name is in use, deletes it all so you can go through it all again. Anyway...
Few questions
- I think my Sonos devices are connected to 2ghz wifi but my phone is on 5ghz. Is that a problem.
- Does it help to have fixed IP addresses for the SONOS speakers
- if i have an amazon echo (quite old) and a SONOS speaker in the same room and say ‘Alexa play radio 4’ which one will listen, or both , or can i change the wake word on the echo dot without changing it on the SONOS.
- what is SONOSNET
- is there a way of voice controlling which speakers are playing , if say, I just want the kitchen on can I say ‘ specific speake off’ or can I start on just one speaker with a voice command?
- Am I right that SONOS speaker with voice control can’t play BBC Radio 4.
If all this info is in a sticky thread , web page for newbies, or help document somewhere please point me in the right direction
Thanks
My Sonos Connect G2 has been connected to for at least 24 hours since separating the 2.4 and 5.0 bands. I’ve got it connected to the 2.4 band. The only issue I have found with separating the bands are that I can’t control my IOT devices from my phone since my phone was connected to the 5.0 band, which doesn’t affect controlling my connect. So, I’ve switched my phone to the 2.4 band to prevent all these connectivity issues.
So far so good. After changing my routers WiFi setting to separate the 2.4 and 5 bands my HEOS Link G1 has been connected all this time. I will connect my Sonos Connect G2 next and test it out.
SONOS does not work well using WiFi that is constantly changing channels.
I had switched from my Sonos Conner G2 to my Heos Link G1, and after a couple of weeks of working just fine, it now doesn’t show up on my WiFi’s network just like my Sonos. After searching my NETGEAR nighthawk AX80 router under the WiFi setting I noticed that it was set to the smart option—it automatically selects whichever network has the highest bandwidth not the strongest connection, which selected the 5 rather than the 2.4. So, I’ve changed the settings to where the 2.4 and 5 bands are separate. We will see if this solves the issues.
I’m going to run a Cat6 line to my garage and see if that fixes the issue. Otherwise, I will have to try to sell this unit or exchange for a WiiM mini streamer. I’ve been thinking of giving one of those a try.
If you’re able to, then you’re a better person than I. My sanity went away years and years ago.
Glad it helped! Networking is such a pain, and Sonos does a great job of exposing every possible issue :)
There’s not enough data to give you any other than the same advice I’ve given in literally hundreds of other threads. Assign reserved IP addresses to your speakers, and refresh your network. And if that doesn’t work, submit a diagnostic and contact Sonos support.
Cautiously optimistic but I just tried your solution and my Sonos app connected right away. Thanks! 
THATS’IT, static adresses! 24 hours without any « unable to connect… » (for my system it’s a lot)! 
Even the Roam can now be turned off and on at will without causing any problem. Thanks so much for the advice, I can start rebuilding my sanity.

I can assure you, the issue isn’t with the Sonos software. It is indeed an issue with the network you have. However, as you’ve expressed an unwillingness to accept solutions, I won’t offer any.
If you have anything that could help others, please kindly share. I’m totally out of ideas. 🤯
On top of what found here - I had this issue (system visible from iPad but not from iPhone app) after switching to a new router. What resolved it is was to disable the router broadcast channel “auto” setting and select a fixed one. Hope this helps.
All my channels are fixed and always have been and I still have the issue. Do you confirm that this solution still works for your system?
I suggest that you refrain from Factory Reset without further consult. Factory Reset rarely cures fundamental issues, but it might accidentally work around something for a short while.
Since upgrading to the latest version of the Sonos App (and some hardware), my iphone cannot find my system all of the time. Some times it does but most of the time it doesnt. The Sonos App on my laptop (Mac) finds the system all of the time. I have tried everything that has been suggested on this thread with no positive results.
Same here. I have been using Sonos since 2011 and I have had setups much more complicated than the one I have now.
iPhone with S2 app
Beam gen. 1
Sub gen. 2
Ikea Synfonisk gen. 2 (2)
(setup as 5.1)
Roam
I have reinstalled everything from scratch multiple times and it works for a couple days then the problem everyone describes comes back to haunt me. I have noticed that turning on the Roam almost instantly breaks the system. Otherwise it seems to happen randomly.
Do something soon Sonos or I’m selling everything and I’m never coming back!
Regards.
Having same issue with my Sonos Connect. I am able to installed everything, and it connects to my network just fine. Then it randomly decides to “Unable to connect to Sonos. Lets fix it!” Today, I started playing music by using the app just fine, and about 15 minutes later I was attempting to change the station, and I got the “Unable to connect to Sonos. Lets Fix it!" message.
I ended up disconnecting my Sonos connect and put a different media player back on my network, and it didn’t have any issues.
I hope Sonos figures out how to fix this soon.
So, what did Sonos support say when you called them?

Have you called Sonos Support directly to discuss it?
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.
I have similar problem , sometimes the app tells me that system is not found and to go through find my system steps , it then gets stuck on finding the system and never does work.
when I remove the app couple of times from background then it starts to work , but its nor reliable solution at all...
The Deco contains a router, unless switched to bridge mode. A router would divide the local network into two IP subnets. Sonos players and controllers need to be on the same subnet.
EITHER: Put the Deco into bridge (AP) mode
OR: Ensure the Boost is wired to the Deco primary node, and that the phone is always on the Deco WiFi. (As insurance, disable the main router’s WiFi.)
1st; Thank You for the quick reply.
2nd; Observation, the interest & amount of likes & replies, would suggest Sonos needs to deploy a more robust solution.
More robust solution? Sonos makes clear in the system requirements that all devices must be on the same subnet. The problem is that many people deploy a WiFi mesh router without knowing what it’s actually doing to their local network.
3rd; After all below gyrations, one iPhone11 can now control Sonos. No other iPads, iPhones, Sonos desktop app.
What gyrations? Are you saying devices other than the iPhone 11 can’t access the Sonos system? In that case you’d better explain what you’ve done so far.

Have you got a Deco 4s Mesh?.
No.
The fact is that Sonos has mixed results on WiFI meshes (in WiFi mode), for various reasons, and the standard advice if problems occur is to wire Sonos to the primary mesh node.
It doesn't work satisfactorily (for me anyway) but others may have better luck.
Have you got a Deco 4s Mesh?.
I'm only speaking from personal experience.
I think trying to wire in a Bridge to the Deco is just doomed to failure personally.
Not a Bridge (obviously, since that’s S1 only), but why exactly is wiring to a LAN port on the primary node doomed to failure?
