"Your Sonos System Not Found" after it was already connected and playing


My system has been connected and having no problems.  Then I started getting fairly regular error messages on all my controllers "Your Sonos System Not Found".  Then the controller functionality returns and I hit play again... only to see that same system not found message 5-10 minutes later.  I'd love some help trouble shooting this problem.

I give up!

When I first set the system up it worked.  Now NONE of the controllers will connect "Your SONOS System was not found".  So, I reset the controller - connect to my existing system, although I have to press the buttons on the nearest device for it to find anything, but it does eventually say you are connected.  click "done" and guess what?

"your SONOS system was not found"

I thought this system was supposed to be easy to set up and use!  I have a pair of play 1s in the kitchen both running wirelessly and a bridge connected to my router (in the room directly above).  I also have a Play 3.  I have tried connecting it using wireless, but it can't be found even in the room next door (very thick stone walls) so I have connected it using devolo home plugs.

It worked - for about half a song - then the whole lot fell over again!

I have tried reserving IP addresses on my router for each of the SONOS units, but that doesn't seem to make any difference.

I still have a Connect in its box which I was planning to use in my lounge (even more stone walls away!) but frankly I think I'll just box the whole lot back up again and take it back.

I've spent the thick end of £1000 and what a waste of money!
Used Sonos this morning. Came back this evening. No connection. Trying to set up a new connection since it won't recognize the old one...no dice.
I have used my system for 2 years no problems.  The last 4 weeks have been crap.  The windows controller can't find it, the iphone and ipad apps cant find it, and quite frankly, your suggestions in this thread and others are crap.  That Bose system is looking pretty good right about now.  You guys had better figure this shit out before you start losing customers.

Signed,

Having the same issue and cannot fix it
morreale, there are others far more knowledgeable than me who may proffer advice. But one thing I noted is that you really only need one of the Sonos devices hard wired to the network. I think it might actually be unhelpful if more than 1 is wired to your router.

I'd try unplugging all but one of them from the network and then switch of all network attached devices including the router and then restart all router first and so on.


hmmm...it was never a problem before. so i hope not. i would much rather use a wired connection when available.
same problem here

it worked fine for a year or so - a few months back - nothing

playbar on wired
play 1 on wifi
connect on wired

i have a tp link extender and now nothing
I'm out of my depth too. We used to be able to bring a laptop upstairs in our company and it would find our Sonos system without a hitch. We'd play music and then leave again. Last week we tried to use the sonos again, and it didn't do anything. Sonos system not found. I try to add an existing sonos system to my controller and it finds it. Great! But then I get the 'Sonos system not found' alert in my controller right after.

I have no clue what to do... tried setting it up with a router, just to see if it would work. Guess what: I was able to see it in my controller and then immediately after it was gone again as soon as I configured the wireless setup. I don't know what I'm doing wrong? We've added signal broadcasters in our building to have better conneciton with our cellphones, but I'm not suer this is actually the problem? I'm not familiar with Sonos, so I don't know how else I can fix this?
I have had the same problem.
Three different Android controllers would repeatedly show "system not found" message even while using the system they would sometimes loose the connection.
What I noticed was that the PC app (PC is wired to the same router one Play 1 is wired to) never had problems finding any of my components, so the Sonosnet had to be working.
I then found that Sonosnet and my wifi were both using channel 6. So I changed Sonosnet to channel 11 and set the wifi to channel 6, this seems to have fixed the problem, as I have had no dropped connections since then.

Good suggestion ThomasBroch. This page has some great suggestions and a guided assistance to follow. Let us know if you still need a hand.
Thank you Ryan S, I had already seen the page you mention, however it unfortunately does not mention the possibility of wifi interference between SonosNet and other wifi. I did notice many complaints regarding this issue on Google Play and originally discounted it as an app problem, until I came upon the solution.
I've recently had connectivity issues with my Sonos system. Constantly getting the "system not found" error. Tried everything that was suggested with no success. Turned off the guest network on my router & bingo!.....no more issues so thought it was worth a mention.
Im not saying this would work for you but it did for me ..... I had constant not connecting issues and drop outs almost the point where I was about to put my sonos speakers on ebay.

However ..... I got an app called "wi fi explorer" for the mac ..don't know if it is available for windows it gave a pictorial view of wi fi channels in my location ( houses all around ) changed from channel 11 to 6 which was less crowded and no overlaps.

Not had one dropout or connection failure in 14 days.

Sonos is on BBC radio 2 about 10 hours a day.

When I go into settings - advanced settings and tap wireless setup I just see instructions on setting up a wireless network, there is no reset option. There is an option further down to reset controller but I don't think that's what's being referred to here. How do I get the reset option?
Thanks.

I think what you are referring to is when you reset your WHOLE wi-fi network. See below:-

Switch off your Wi-Fi Router
Switch off ALL your Sonos kit
Switch off ALL devices connected to your Network
- Computers, Laptops, Tablets
- Smartphones, thick phones
- NAS

Switch on Router. Wait until it has re-connecte to the internet
Switch on Sonos Bridge and/or Boost, Connect - Wait a minute or two for them to connect
Switch on your Sonos Plays and Playbar
Switch on all your other network devices


Also, as the above post make sure that your SonosNet is on a different channel to your wi-fi and make sure the device connected to the router via cable is as far away from the router as possible.

If all this fails then submit a diagnostic and post here or phone Sonos with it.

My Sonos system has recently developed an issue that I haven't seen before. Living room: 2 x Play 1s and sub. Kitchen: 1 x Play 1. Right Play 1 of the stereo pair connected to router via Ethernet cable. IPad and iPhone controllers on the same wi-if network. On several occasions recently I've used the play/pause hardware button on either the living room or kitchen speakers to play music. However, when opening the controller app to change the music source, it can't find my Sonos system even when both rooms are playing music. This behaviour is seen on both iPad and iPhone.

In spite of fully resetting the system, iPad Air 2 is still showing intermittent issues with connecting to Sonos speakers. The Play/Pause hardware buttons on all speakers are working fine. On a couple of occasions, the Controller will find the Sonos speakers after being left open for around 10 minutes. Interesting that another poster on Windows 10 is experiencing similar issues:

We'd love to look into this further. Can you send a diagnostic from your Windows 10 controller after it's found the players?

This problem sounds like an issue with the security software on the PC or something wrong with the windows network configuration. Do you run any firewall or anti-virus software on your computer? Also, can you check what the network profile is set at? It should be Private or Home, not Public. I'm going to reach out to that other thread as well, if he's experiencing exactly the same problem you are, it'd be best to continue over there. You can add your diagnostic confirmation on to that thread.

I'll submit diagnostic on the other thread. FYI, controller is on an iPad Air 2 with the latest version of iOS. No firewall or anti-virus! Network profile is Home.

Thanks testcard, I pulled up the diagnostic from the other thread. Since you're not seeing this issue on a Windows10 computer, just the iPad and iPhone. Might as well keep these threads separate. My apologies on before, I somehow read your comment to say that you also had the Win10 trouble.

Does rebooting the router resolve the connection trouble with the iPhone or iPad? Even temporarily. If it does, I'd recommend giving us a call on our support line. A technician can assist further investigating the system live.
I have similar problems. Diagnostics number is 5525821.

I've had many issues keeping my apps connected to my SONOS setup, and I've redone the whole setup about 10 times now since i bought it last month.

I have a wireless setup, no BOOST device. All is working fine now thank the gods, and as we speak the SONOS is playing some radio station.
On the iPAD the SONOS APP is connected to the device, but my PC SONOS Application cannot find the SONOS. But I'm sure it is connected!
I can see the SONOS on my wireless router, with IP address 192.168.1.4.

I would love to just be able to point the application to the bloody IP address... Shouldn't be that difficult, should it? 😠
Is your PC wired to the router? Some routers won't forward discovery broadcasts between the wired and wireless segments. Sonos relies on these to locate the players. And before you ask, this is entirely compliant with the UPnP standards. Some routers simply don't play ball.

I have to say that having a wired component -- a BRIDGE or BOOST -- would probably solve your problems.

Hi Annoyedbysonos,

It sounds like your BRIDGE is losing communication with your router from time to time. This may be due to a faulty ethernet cable, faulty ethernet port, or IP address conflict. Please start by swapping out the ethernet cable and see if that helps. You can also try swapping ethernet ports on your BRIDGE and Router.

If the issue remains, try wiring a different Sonos unit into your router and see if your system returns.

You can also try the steps outlined in this FAQ.

If none of these steps help, please let me know and I'll create a support ticket for you and get you in contact with our phone team for further troubleshooting.
