I’m so tempted to download the newest app and speaker updates when I see some say it’s great. But then when I come across posts like this one, I say no way. I’ll stay where I’m at and use the SonoPhone app..it has zero issues. 

​@Dan U - sadly it’s not just wifi/router issues.  Sonos decided they want the control of your system to reside in the cloud not locally. So you add all of the potential issues that can produce and you can see why even the most recent press reviews claim this app intro was a “disaster”.  Some fans here have NO problems, but that does NOT represent the vast majority of users as reported many times in forums, app reviews, tech press, and more.

​@Dan U Could you state the problems you have with the app?

I thought it was getting better but the Sonos app still having issues with disappearing speakers extremely slow response dropping of audio streams skipping randomly of audio streams. It starts to play a song at about 1/3 of the way through it just skips to the next song or the lead in is cut off or just the end is cut off. I just never know when it’s gonna throw another little glitch at me. It will work fine for a couple of days and then I can’t get it working. One of the biggest complaints is my speakers randomly just dropping off. I feel that this last update backtracked a little in the stability.

Don’t get me wrong it has improved but it’s still a pain due to the random pop-up problems. I was thinking of purchasing the Arc ultra but these continuing problems despite some recent improvements convinces me not to do so.

If you like to get help, please tell us more about your network and Sonos system configuration. 
Maybe someone here on the forum can give some advice to optimize your settings. 

Thanks,

I’ve been through the configuration with the Sonos system and the network multiple times with Sonos on the phone plus on my own. I’ve owned Sonos speakers since they started and I’m familiar with the set up and various idiosyncrasies that can cause problems at least up until the new app came out.

I have two ERA 300, 2 PLAY 5 (gen 2), 2 Play 1s, 1 SUB 4, 1 SUB (Gen 2), 2 Sonos Roams, 1 Sonos Playbar, and 2 Ports. 
I have a TP link AX5400 Wi-Fi router. 

I think most of the problems has to do with the change that Sonos did running everything through their servers then rather than allowing us to stream directly. That adds additional delay which may be causing some of the other problems.

I’m located in a remote area of Northern California the closest house is more than 300 yards away so I don’t have much in interference from my neighbors. 

​@RKP 

Ok, thank you for the information. There isn’t so much cloud control as you suspect… most communication still is on local network. 
Is there only your router or any other devices like wifi extenders, ethernet switches, power lan devices or so on?

If not, check your routers wifi settings. Are there set fixed channels? Same ssid for 2,4 and 5 Ghz wifi band?

only my router no Wi-Fi extenders to Muddy things up, No ethernet switches, no Power lan, etc…

Very basic set up it’s mainly used for Computers, Music and video.
SSID is Different to differentiate the different frequencies.

it could work well for days it’s just when it goes south it drives me nuts.

I think it might be cosmic rays or a Gama ray jet causing soft failures in the Sonos, internet provider, or my electronics .

Wow, that really sounds strange. 
I just can imagine there‘s a special option in your router settings that may cause that. Or sometimes there are some interferences. 
So best to do before digging is sending a diagnostic and call Sonos support. 

A while ago I had an app on my phone that would show all the 2.4 GHz signals so that I could determine if there was any nearby interference and also what channels would be best to use and at that time no nearby interference was detected.

I already went through the diagnostic route with Sonos.

For today this morning the Sonos system was buggy this afternoon the system was flawless. If my network set up was an issue I would think I would have consistent problems. So you you’re right interference may be it. I guess I’ll see if I can find that app and check again. I will also check my router settings but I don’t expect that to be an issue.

Have you “reserved” IP addresses for all of your regular network clients? This is always good practice, even though your issue seems more like interference.

Are any of your SONOS units wired to the network? Obvious sources of interference would be Microwave Oven, child monitors, wireless video cameras, and SONOS units too close to the router. SONOS support should notice if one or more units is being buried in interference. Submit a diagnostic within 10 minutes of an event, log the diagnostic number, and call support.

Make sure that your router setting will allow data transfer between 2.4 and 5GHz bands.

No Reserved IP addresses

I’m familiar with the microwave ovens interference issue.
There’s no child monitors there’s no Wireless video cameras and the Sonos is not too close to the router except for the playbar. I use the ethernet cable between the router and the playbar.. 

Yes, I’ve done that with the customer Support at Sonos a couple of times immediately generating a log and giving them a call because I know it could be a while before I’m able to talk to my person. But no matter what is done the Various Random problems randomly comes back.
The router does allow data transfer between 2.4 and 5 GHz bands.

At least today it’s behaving itself.

​@RKP 

Oh, you didn’t mention before that at least one Sonos device is lan cabled. Do you have Playbars wifi module still turned on or did you manually turn it off?

Are there rearspeaker and / or a sub bonded with the Playbar? In this case the wifi module has to be turned on.

If it’s still activated the Playbar does create the SonosNet and your system will operate in a mixed mode using router wifi and also the SonosNet. So your interferences may come from your own network. 
Within Sonos app you can choose channel 1,6 or 11 for SonosNet. It’s on 2,4 GHz and all other SonosNet supporting devices will try to connect to it. Your routers 2,4 GHz wifi should be set fixed also to one of these three channels, but a different one than SonosNet uses. 
The other option would be to use router wifi exclusively and turn Playbars wifi module off. But that option only makes sense, if Playbar is used stand alone without sub / rearspeakers.

I’ll check the channels for conflict, but 90% of the time the playbar not even powered on since it’s a guest bedroom. But you’re right that could be an Interference issue. But when I had the problem the other day the playbar was not powered up.

The playbar is standalone for the TV in the guest bedroom. There is no sub Or rear speakers with the playbar. 

Ok… in that case I would try to deaktivate Playbars wifi module within Sonos app room / product settings. 
Maybe some devices are still searching for the SonosNet if the Playbar is cut from power. Switching from SonosNet to router wifi and vice versa can take up to 10 Minutes and cause problems. 

OK I’ll give it a try.

There was just a new update, I’ll see if that helps also.
