Old subject of systems not registering with the annoying “check your network” message.   There is a hint in the “Check the time and date on the unit”    I found out by eliminating all the working SONOS speakers and leaving just the unregistered one, I had to sign in, but finally got past all the Registering failure.   I went to system and  checked TIME and DATE and it said Jan 1 2001 and 12:00     (The default).  I tried to make it update to Internet Time so it would be accurate but it never updates.   

My guess is the clock in the speak has a Lithium button battery that has gone dead after 8 years.   And Registration can’t happen if the time is not accurate for some crazy reason.   CS support is useless.  This guy blamed my Internet provider which is the old ruse of years ago.  Now with IPV5 and IPV6 it’s so standard that excuse is like saying it’s your 110V power outlet.   Net Net, the clock is dead and the unit will never register.   I’m going to take mine apart and see if I can update the battery.   It’s a boat anchor anyway.   

That old and un-updated it might be looking for an NTP server that no longer exists.

If you can check your router’s DNS log you should be able to see what server it is looking for. If it is a dead address use the router’s DNS override to remap it or a live NTP server.

I do that here for several devices that try to be sneaky and use NTP checks to call home to the manufacturer in China. Remapped they use my router’s NTP and leave no trace on the Intertnet.

 

Dead battery is a possibility but I’d think Sonos would use something rechargeable so leaving the speaker plugged in overnight might see it recover a working charge.


Hi ​@Darrent200 

Welcome to the Sonos Community!

Sorry to hear about the issue your are having with updating your speaker.

I have not come across this time/date issue before, so I am not convinced that you are correct. I heavily advise calling in to our technical support team before opening any units up - a speaker with very old firmware will not be able to update in one step and will need assistance from our team.

I hope this helps.
