S2 system update is terrible and my system rarely functions properly now even though it was fine 99% of the time before. Look at the Apple reviews recently. A great deal of them are 1 star. This app is extremely buggy. I have about 11-12 speakers and they’re basically functioning as ornaments now. 

As explained many times in this thread, it isn’t the sotware that you’re having issues with, it is your local network, the great majority of users are not experiencing any issues with either S1 or S2. 

Without details of your setup, two rather effective but general things to do are:

1. Read and apply such solutions as can be found in the wifi interference FAQ. This kind of issue is by far the most common issue plaguing users.
2. Refresh your Sonos network by unplugging all Sonos devices from power. While they are unplugged, reboot your router. Only when the router comes back up should you plug back in the Sonos devices.  This resolves several potential issues, by forcing both the router and Sonos devices to reboot, and reconnect. But it would only fix one of the potential issues if the Sonos devices are powered off while the router is rebooted, if they remain powered on, it won’t have the same effect.

Sonos is a networked speaker system, so if there is an issue internal to your network, it will reflect on the Sonos performance. Of course, the above two potential solutions probably cover only 98% or 99% of the potential issues, there are certainly less common ones. If those two solutions don’t work for you, I would recommend that you submit a system diagnostic , and call Sonos Support to discuss it, or post the number here.

There may be information included in the diagnostic that will help Sonos pinpoint the specific issue and help you find a solution.

When you speak directly to the phone folks, there are more options available beyond just the diagnostic analysis. 

What nonsense. Lots of people are having problems with S2.  I would suggest people look at the app reviews in the App Store rather than listen to the denialists in this thread. After S1 working perfectly fine suddenly all these problems. All because people have got network problems? Laughable

Sonos - please listen to your user community. There is something seriously wrong with S2. We all have a lot invested in this product. This S2 rollout has been an absolute failure. I have four rooms on my network and now only one works. Rooms appear out of no where and then disappear. What is the solution. Can we go back to S1?

Agreed.

4 Play:1s and 2 SLs working fine on S1 app…  Suddenly though, the last update to S1 app causes a crash whenever searching for a radio station.  So I upgraded to S2.

Now, none of the SL speakers show up in S2 app.  I’ve discussed on a forum thread here which led to calling support.  After clicking through multiple “solutions” I finally get a phone number.  After nearly 2 hours on the phone I’m sent an email of suggested router configurations… Like really?

If my all my speakers worked perfectly on S1 but then suddenly on S2 the SL speakers do not work, how is it an issue with my router or network which hasn’t been changed any time inbetween S1 to S2? Clearly there is an issue with the new system.

On my router’s connected devices I see TWO different Sonos:  “Sonos Inc” and “SonosZP” so seems like SL and Play:1 have two different clients but yet the S2 app can’t seem to ever find one of them.

As others have said, wanted to buy more Sonos for Christmas but with this I’m thinking I might need to trash all these speakers and find a whole new brand.  Absolutely a disgrace.  Especially the time I wasted with Sonos support and diagnostics. 

Yes.  Same here.

My Play:1s all show fine.  The SLs though…  They come and go on the app.  And when they do come on the app and I attempt to play something I get a “cannot connect” popup.  And then on the Windows controller they don’t show up at all, just on the Android app.

Just horrible.  How did such a great system become a total dumpster fire?  Especially when downgrading is such a hassle.

As a follow up….I finally came across a couple of speakers that had not been reset or upgraded to the new version of the app.  Unfortunately, I could not get all of my speakers to join the network wirelessly, so I was forced to connect one of my speakers directly to my router.  I am using the original Sonos app, but every time I access it, it tries to launch the new app. It is easy to mistakenly do this.  At the end of the day, I feel like I ended up surrendering, which is so disappointing since this worked so well before.  I guess I am just glad that I have music piped through my entire house at this point.  

I had really bad issues with my Sonos S2 system with 2 x Sonos Ones.

I assigned them static IP addresses and for some reason it is much more stable now. I have an Asus ZenWifi mesh network.

That’s the more permanent way to do 2. , in my post above. There just appear to be some routers that seem to regularly lose position in the IP table, and since Sonos does a soft reboot with each software update, it hits that issue more frequently than most devices. 

8 years with Sonos, 16 components now, (8 were recently upgraded so I could use S2 features) - purchased units almost every year.  Over years of trying to stabilize my system with the help of some high-level Sonos engineers, we’re still forced to WIRE over half of our Sonos components to get even reasonable stability!!  (wireless audio - my arse!)

Indeed I could have wired the same rooms for HiFi speakers had I not bought into the marketing hype Sonos sold all these years. 

Look! S2 is WAY MORE unstable than S1 and even if the fanboys here won’t admit it, many inside Sonos will (anonymously of course).  

I was an I.T. exec for decades, live in small home with no Wi-Fi interference for neighbors (who are far away) and I know more about routers/switches/modems/Wi-Fi than most consumers.

8 years of attempts to isolate Sonos units, Wi-Fi interference, cell phones, on and on! 

Several top end routers, all Cat 6 (or better) cabling.

Every single aspect (including a detailed network diagram) scrutinized by Sonos engineers year after year! 

100’s of diagnostics submitted, traffic managed, Static IPs assigned, then un-assigned, multiple units Wi-Fi turned off then on then off again. 

Engineers agree, I’ve done EVERYTHING CORRECTLY AND THERE ARE NO ISSUES WITH MY HOME OR SET UP!!!   Their advice; WIRE UP MORE UNITS!!  

FORGET Sonos HD radio!  Unstable b/c of the limitations of even Gen2 Sonos units.  Canceled my subscription after support admitted that it probably won’t get better soon!

And don’t get me started on the horrific management decisions to gut support and software programming staff, while farming out support to off-shore, contracted, companies with uncaring and under-trained staff.  And lastly the brain-dead, poorly managed roll-out of the S2 line! 

The few remaining top tier support staff are excellent, dedicated, smart, friendly, and helpful but there are limitations to what they can control. 

Rant off - Have a lovely holiday everyone and STAY SAFE!

Like many others here my Sonos system has been ruined since the launch of the s2 app. Basically for me when I load the app it takes 10-15 secs for the app to respond on my iPhone so I can’t change volume etc. I’ve since sold both my play 1’s and both play 3’s and as much as I have loved the play 5 as a lounge speaker I think it’s time to get rid. Such a shame as I was so invested in the setup but can no longer recommend 

Thanks for saying this!  You can tell the pattern of “resolution” that Sonos is using. My solution is now when I see people at Best Buy looking at Sonos, I tell them NO! I printed out one of these community messages and taped it on Sonos display. It lasted half a day before it was removed. I want the quarantine to be over just so more people will see it!  Bottom line; we don’t need a community forum, we need Sonos to do their job. Nevertheless, whatever at this point ain’t enuf.  I’m done. 

i am another user to the list that cannot listen to music anymore after upgrading to S2 → my whole system of 4 devices is stuck in limbo → cannot upgrade and therefore have limited functionality thus cannot add remove items. have factory reset my PORT and therefore cannot use it now at all since have limited functionality until i upgrade. 2 sessions of 1 hours each with support didn’t help to any solution other then mentioning that my PORT has actually the latest version of the software. However although no other devices are connected it still wants to do an upgrade to whatever version is needed?!

10 year of sonos just works and listing to music → has changed to no music available and calling sonos support with no anwers

this (s2) is indeed a nightmare
