Why is it every few months an app update bricks all my speakers!!! This just keeps getting worse and worse. What kind of a company is actually coding this rubbish???

Hi ​@S0nos5ux 

Welcome to the Sonos Community!

I am sorry to hear of the issue you are having with your Sonos system, though you have not stated why you felt you needed to factory reset your entire system.

To be clear from the outset, we recommend that you never reset a speaker without consulting our technical support team first, and we very rarely say that you should factory reset your entire system - even after you have spoken to us! It is overkill, plain and simple.

That you state that you need to do the reset after a system update suggest to me that the issue lies with the fact that the entire system will reboot after the update - I suspect that the issue actually lies with your router not issuing fresh IP addresses to connecting client devices (such as your Sonos speakers) properly. To mitigate this, I recommend that you go into your router’s settings and reserve IP addresses for all client devices that regularly connect to your network, but especially for your Sonos devices.

It is likely that you only spot this issue occurring with your Sonos devices because your other WiFi-enabled devices are not interested in talking to other local devices - only to the internet. Because your Sonos speakers (and the app(s)) frequently communicate with each other, conflicting IP addresses can cause such issues with them (and the app).

If you do not know how to reserve IP addresses in your router’s settings, please consult either the manual, your ISP (if they provided the router to you), or contact our technical support team who can remotely connect to a computer of yours and perform this task for you. They can also investigate further should reserving IP addresses not be the answer I think it might be.

A shorter-term fix would be to simply reboot the router by switching it off for at least 30 seconds whenever you are unable to connect to your Sonos system.

I hope this helps.

Hi there, thanks for your reply,

 

The router is already set to retain IP addresses. The issue is when the app has received an update the system disappears. Nothing I do can get the speakers to reappear. The only way to get any of them back is to switch off holding down the reset button.

 

Why does updating the app cause such issues???

Hi ​@S0nos5ux 

Thanks for the additional info.

Why does updating the app cause such issues???

I don’t know, and it really shouldn’t - there are literally millions of our customer for whom this is not a problem in any way.

Do you only have the app installed on one device? Do you see the same results on any other devices, if you have them?

To be clear here, it does not make any sense that updating the Sonos App (not the Sonos system) would require a reset of the speakers, rather than a reboot of the device running the app, say, or the router. An update of the Sonos system will cause the Sonos system to reboot, but I know of no good reason why an update of the Sonos app only would result in the condition you describe.

highly recommend that you contact our technical support team the next time you come across an issue even remotely resembling this one, and before taking any drastic steps to try to resolve it - we can see if your system is online or not, which is the first step in determining if you should be able to connect the app to it or not. In case it is of use to you now, I just looked and your system is online, but I suspect that is because you reset it and set it app from scratch again.

I hope this helps.

Sadly the in-app-help will tell you to reset your devices when it really, really should not. You never need to reset a device unless you sell it.

You are having network-related issues, and as the Sonos Factory Reset FAQ actually says, a factory reset isn’t going to change that. If only the person who wrote the help text had also read the FAQ...

The whole system needs to be in sync. If you’re only updating the app, it may get out of sync with anny update on the speakers. Try using the Check for Updates in the app next time, to be sure the speakers are up-to-date.

1. Your speakers are not being bricked if you're able to keep using them 

 

2. Once you have things working again, turn off automatic updates

By this do you mean you have reserved addresses for all Sonos in the router's DHCP Settings? 

As far as I can tell it is not the app, I've spent many hours investigating this. It is either a router issue, because changing brands of router can fix it, or it is a Sonos issue because reserving addresses fixes it, or again and most likely, it is a combination/interaction between the router's DHCP server and Sonos DHCP client.

I have not seen any reports of the reservation failing to work on a properly set up network. Mainly only one DHCP server. That has the addresses reserved, all Sonos powered down, router and controller rebooted and then the Sonos powered back up. Skipping the network refresh can result in cached data in the router or clients using old addresses and failing on power-cycle or reboot.

Before I learned proper network setup, I had Factory Reset a few times. That was in 2005. Now that my network is correctly setup, I don’t Factory Reset. This is not to say that I haven’t had a few “discussions” with routers and switches as I changed locations, ISP boxes, and infrastructure, but there were no SONOS Factory Resets associated with those adventures.

Also, why not provide information on your network be your own router or provider by your ISP. If you have a mesh network or extenders (which are devices you arbitrarily add to your network not to be confused with a mesh) there may be some mis-configuration causing speakers to dis- appear.

Why is it every few months an app update bricks all my speakers!!! This just keeps getting worse and worse. What kind of a company is actually coding this rubbish???

on which device do you upgrade the app? is it Android, iOS, Windows or MacOS? do you have any firewall products installed on it?
