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.

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 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.

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?

same problem here

playbar on wired
play 1 on wifi
connect on wired

i have a tp link extender and now nothing

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.

I have 6 Play 5s, 2 Connect Amps, and 1 Connect and have been experiencing the "Your Sonos system was not found"" error now for at least 8 months . I had been using the beta software but have switched back to release and still have the issue. I have been using the system for nearly 2 years with no issue.

Most of the devices are hardwired to my network. I have reset the controllers and the devices countless times now. I have tried most of the suggestions in this thread.

A quick post to let anyone know how we resolved it. Spoke with technical support and it was not working because Sonos doesn't work well with TP-Link wireless extenders, which i wasn't aware of, so as i had the boost to set up the Sonos network the only step that i hadn't taken was to forget my home wifi network, sounds like it was picking up both the Sonos network and my wifi network and they didn't play nicely together.

So anyone else looking for a solution, go to settings > advanced settings > wireless setup > next, and then there should be a reset button to hit which wipes out any wifi setup and lets the boost work on its own. Not something that i had read anywhere but as ratty points out i should have called up ages ago as it was a simple fix.

All fixed, very happy now!! Now to get back to the shop and buy some more speakers

My point is that when i search for the problems it does seem that a lot of people are having very similar issues spread over a large number of sites that they are struggling to resolve, and the main strength of Sonos system is supposed to be its connectivity between all of its systems.
The vast majority of connectivity issues are down to:
- a troublesome third party component, often a router
- a basic local network issue such as a duplicated IP address, which a network reboot usually fixes
- wireless strength/interference problems, and Sonos is no different from any tech in needing to abide by the laws of physics

Let Sonos Support help.

I am assuming with 16,230 replies you are possibly working for Sonos anyway or an avid avid fan?

Sonos employees are clearly identifiable. I'm just a former user moderator from the original Sonos forums.

Hi ratty, and quite a few others are likely to be having problems don't post, i have been struggling with it for 3-months and this is my 1st one. Same as the number of people who are ill is not indicated by the amount of people who go to the doctors as many more will suffer in silence, so it works both ways.

I will sit down and have a run through and see if i can get to the bottom of it but it is very frustrating.

There does seem to be a huge amount of people with a similar problem
No, a substantial proportion of people posting here have problems. But then it's a support site, and those happy with their system don't usually take the time to brag about it. Likewise in a hospital or doctor's surgery you tend to find that most people are unwell, but that doesn't reflect the entire population.

Sonos has sold millions of units. If there was a systemic problem this site would be swamped with complaints.

I'd suggest you contact Sonos Support by phone or email. They should be able to get you up and running, then subsequently ask you to submit a diagnostic to see if there are any vulnerabilities due to your local wireless environment.

I have to add to this, i got Sonos in July after hearing great things and have had nothing but problems. I have a Play 5 in the Kitchen where i also have a strong wifi signal, and a Boost in my living room on the router and a NAS drive.

Have had problems from the start, could connect the speaker initially, but kept on finding that when i went away and came back in and found that it couldn't find the signal again. I gave up on it and went back to the bluetooth speaker resolving to go back and start again. Have had another go today and started from scratch to find the Sonos Boost, and then tried to find the speaker in the kitchen, and cant' find it again, no matter what i do.

So not sure what to do, with the NAS i have invested almost £1,000 to get this great Sonos system but its currently completely outplayed by my £35 bluetooth speaker which i can at least rely on.

There does seem to be a huge amount of people with a similar problem, you would think with all of these competing systems coming out you would pick up your game guys.

Will try and make contact and see if i can get it resolved.


Thanks

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.
With the number of players you have in your setup it'd probably be better to run off of the dedicated wireless, that way you don't need to worry about them taking too much of your wireless bandwidth. You could certainly test it out if you'd like. 

Let us know how it goes, if you have any more trouble can you send a diagnostic from there? If you don't see any of your players you'll need to check your wireless network too before you can send one.

Just another note, if you do wind up unable to see your Sonos system at times, see if you regularly have trouble while connected to one of those SSIDs versus the others. Your controller needs to be connected back to the same DHCP server that your players are connected to, so we recommend with multiple routers you have only one of them assigning IP addresses.

Ok, I've left one SSID on 10 and the other on 1.  6 is open.  

Should I instead or additionally get rid of the bridge and do the new wireless setup on my wifi?  What difference would that make?

Thanks, quite the network setup there. It looks like you might have a wireless network broadcasting on each of the main channels, 1, 6, and 11 (based on SSIDs and strength of the signals). Several of your Sonos players are having trouble connecting through the interference as they're set to channel 6 presently.

Would you be able to clear off one of those three channels so that you can set Sonos to it alone?

Sounds like a IP address issue.  I would unplug, reboot your router, and then plug back in to get a fresh IP address.

It's started happening to me every morning with my Sonos Amp. It can't be found on my laptop or phone but if I reboot the Amp it works. Every morning it is the same for the last week or so.

Has something changed in a recent update or something?

When you're having trouble connecting, what error message do you see? Is it that you don't have any rooms that can play music or do you see a Sonos system not found?

There could be a number of things that might occur at night which could cause this sort of issue, a good example would be a neighbor turning on their baby monitor which runs on the same frequency as most wireless devices (2.4 GHz). This is simply an example though, it's hard to say without more information.

Do you mind sending a diagnostic from the system when you have a chance? Though you can't do this if the whole system is missing, you can do it if you just see the BRIDGE or when it's back up. It'll still contain some good information for us to start with.

Unplugging the BRIDGE seems to work tonite when it got funky. Why mostly at night?

Same thing is happening to me. The system has worked flawlessly for 6 months and now, for apparently no reason, none of my devices seems to recognize the sonos speakers. Could it be because I have subscribed to Apple music recently?

What shall I do?

I have the same problem lately.  Last nite, nothing could connect. So, I restarted the whole thing from scratch -- new.  Worked great all day. Now this evening, nothing.  No Macs, no PCs and no iPhones or iPads can find our Sonos boxes.  We have like 7 and now nothing?  What's up?
