16.1.1 update not good ...

Mine was surrounds in my main room 4 times I ran the update tna still missing had to reboot and remove the surrounds before they reappeared sigh 

then had to redo truplay again kind of used to it failing in some way every time now 

Thanks but was a network engineer for 20 years before retiring last year 

I hope you sort your issue out, please let us know when you've sorted your issue.

I don't have any issue after the update with my system. IAs I said issues with updates are 99% caused by network issues .  I suggest that you power down all of your Sonos devices for a min of 5 secs and power back on.

Try checking for updates again and if you still have your issue then submit a diagnosis and post the id on this thread.

To be honest it’s a little frustrating when people always say ‘it’s your network’ as the reason things fail.   In many cases, sure that is plausible — but In 99% of cases ?  Well, where are the facts to back this up? 

I like to think I know what I’m doing.  I’ve been with Sonos since 2009 when updates were a breeze.  I have a fast fibre connection, I have a small-business grade router, and I have *all* devices IP bound by MAC address.   Everything on my network is rock-solid and I can stream ultra-HD (4k) video without issue.  However Sonos updates never work unless I remove Play:1’s as surrounds to my Beam, and I do mean never.   If I don’t do this everything gets horribly screwed up.  Others have this issue.  I don’t know what causes it, but it sure ain’t my network.

There is little doubt in my mind that the change made a while ago, which causes a greater length of time to apply an update has confounded many of us. The system doesn’t seem to wait until all devices have finished rebooting with the latest data before the polling occurs, especially on devices with older and slower CPUs. So we get false positives sometimes, that suggest we need to run an update again. Sometimes, as @UKMedia suggests, that is indeed a necessary thing, most often due to problems in the WiFi dropping the update process (I think). But sometimes it’s that false positive, and we just need to wait ( not sure how long, I usually wait half an hour) before checking for an update again. It’s mildly frustrating to me that this is the case. Probably because in that half hour, I can’t use the system. One way, pointed out by others, is to set up an automatic time for the firmware to be updated on its own, so it happens ‘magically’ and all I have to do is update my controller. OCD makes this challenging, but it’s a good suggestion. 

Just register to say that thanks to update to 16.1.1 my 2.5 years old sonos beam gen 2, stopped working and seems completely dead with flashing white light. Support gave me nothing but a 30% discount to buy another one so yeah, fantastic situation. A very recent beam (< 2 months, different hardware version) gen 2 has been updated without any issue. No powercycles or network issues in the process, looks like the update won’t work with old models. 

Ey, thanks for the answer. I did yes, it’s connecting through ethernet. The router even give it an IP. Factory reset etc won’t work. Tbh the issue is more in Sonos than in the device, everything feels too convenient since it broke after an update and just a bit after the guarantee expired. Support did almost nothing before send the hardware to recicle. The usual 30% discount is ridiculous.

Sometimes they're designed to do exactly that
