Recent Update has all Sonos Devices dropping connection

Do you have static reservations for your IP addresses? The most common cause of post-update problems is IP duplication.

My system seems pretty stable, and has been for some time. 
 

As far as your problems, if you’re looking for some help a bit more information would help. Which update? Are you running wired or wireless? Wifi or SonosNet? Have your neighbours changed wifi channel, causing interference in your system? Have you rebooted your router as well as all speakers?

Yep, all static IPs.

Is the Sonos system connected to the Orbi WiFi? Or is there a Sonos component wired (preferably to the Orbi primary node), putting the system onto SonosNet? 

Thank you, but I'm not looking for troubleshooting help. I have already isolated this to Sonos device connectivity to WiFi using IP packet analyzation with a sniffer. The data has proven there is no issue with the network, devices on the network or from any interference. The disconnect is being caused by the Sonos devices themselves…. locking up and needing a reboot to reconnect, which is indicative of a firmware or OS issue, which is exactly what was recently updated.

The system has never had an issue until this last system update, and nothing else has changed.

I’m looking to see if there are others experiencing this issue.

Actually, it is indicative of duplicate IP addresses, something we have seen thousands of times over the last 15 years.  These happen when the router loses track of its IP allocation table due to a crash or a reboot, and starts handing out IP addresses that are already in use.  The symptoms often show up after an update, because an update causes Sonos devices to reboot, and they all request a new address upon startup.  So the sooner you stop insisting it is some widespread error in the Sonos firmware, the sooner we can get it fixed.

Reboot/power cycle the following, in this exact order, waiting till each comes up before moving to the next:

Router/modem

Switches/hubs

Wired Sonos devices

Wireless Sonos devices

PC/Laptops/streaming devices

Printer and other peripherals

You can also switch WiFi Off/On on your phones/tablets

After that, you can eliminate the problem entirely by going into your router setup and reserving IP addresses for all you Sonos devices.

@Craigster did say he’s running with static ip’s. He hasn’t said whether he’s done a sequential reboot, starting with his router. (He also said he’s not looking for help.)

I'm not insisting anything, I simply asked a question. Your answer… and arrogance… is not helpful…. I suggest you read in detail before you just repeat the same answers that everyone else does which have nothing to do with the question asked. Of course, everyone uses DHCP, right? And its the root of all issues…. wrong in this case. I don't use DHCP and never would…. if you really understood networking and security you would know that DORA doesn’t apply… even if you know what DORA meant… but you probably felt great in front of others that don’t know any better.

Yes, in 15 years, every issue was user configs and routers… never Sonos firmware or devices. Enjoy your little bubble and your lack of reading comprehension and technology skills.

Please close the thread.

That’s strange, since Sonos relies on DHCP.
