Sonos app not picking up Sonos

Can you tell us a bit more about your set up? Which devices, what does your network look like, that kind of thing.

Hi,

thanks for your reply… I have 9 speakers which include the following:

2x Sonos beam

4 x Sonos one

1 x Sonos Three

2 x Sonos 1

due to layout of the house, unfortunately all are on WiFi as I cannot hardwire them. Just on my standard BT router. I could go and change the channel of the router or create fixed IP addresses for them, but wondering whether a Sonos boost would help by taking all of the Sonos traffic, and if that is the reason my app keeps losing the system and won’t connect at all to it?

jjst don’t understand why when I open the app it doesn’t connect to the system and doesn’t even acknowledge there is a Sonos system at all.

I’ve also been experiencing this since the 12.2.3 iOS app update this week. My iOS app has become almost useless, however the desktop app sees all of my devices perfectly. It has to be the recent iOS app update as the desktop app sees the devices and I can also make SOAP calls to the devices ok and furthermore they ping and answer fine. Just the recent app upgrade is what seems to align with the functionality loss. 

Updates are blamed on here for everything, and it hardly ever is the update.  On the rare occasions there has been a bug, there are hundreds of posts in no time.  So, @dutchie027 , your problem is almost certainly something local.

To answer @andrew_wilson1981 , (and @dutchie027  if it applies to you), please would you move a speaker close enough to the router to be able to connect it temporarily by Ethernet?  Wait a few minutes for the system to reconfigure and see if it is any better.  My reason for suggesting this is that with some routers, it can cause a problem on Sonos if the controller device connects to the router’s 5GHz band.  With a wired device, this issue is bypassed.

Either way, the experiment will tell us something.

If the advise from John B does not resolve the issue, and if you are on iOS devices, try this:

Switch off wifi assist https://support.apple.com/en-us/HT205296

Also, switching off private address may help https://support.apple.com/en-gb/HT211227

As @ClausN’s advice is very quick to implement, you may like to try that first.

I get that apps get blamed but if you look at the troubleshooting I’ve done that points solely to the app. The desktop controller works as does SOAP calls. I’m a computer engineer and I’m telling you it’s not network related. Also I can pinpoint it to exactly the time the app updated and it’s not replicable on the desktop nor an Android device. Only iOS (both iPad and iPhone) devices. Both running the latest versions. 

@ClausN can you elaborate more on the private networking address aspect? The idea behind private addressing is a different MAC per WiFi network. If you’re always using the Sonos system on the same WiFi, private networking won’t matter one bit, will it? 
 

For example with Private networking if you use your phone on 7 networks and constantly go to Google you’ll be seen as 7 different devices, but if you’re always using WiFi from the same SSID, private networking doesn’t do anything, it doesn’t randomize the MAC over time on the same network only on different networks. On the same network would really mess with DHCP leases. 

For reference here is Private Addressing. It states across different Wi-Fi networks, not on the same one. You don’t get a new MAC every time you leave and rejoin the same network. 
 

Further Wi-Fi assist dumps you off of Wi-Fi altogether which then renders the controller inaccessible as you are no longer on the same network so it’s not that either because my desktop controller can see all 9 devices fine where as my iOS apps only see two or three at any given time. 

Is your iOS device up to date?

Are there updates available for your router (log into your routers admin page).

Note: Just because you have Automatic Updates turned on doesn’t mean they have been installed.
