Reconnecting my Sub

arepo wrote

Is there a way to connect my Sonos Sub back to my system it was before now I can’t. It keeps asking me to update it
 

If it’s asking you to update it, do that. Then it should go back into your system. 

You’ll need to update all your devices (and app’s) to keep them in sync. 

I’ve tried to update it but it doesn’t work. It was working fine before all I did was move it to a different spot of my living room. 

Do you get an error message? 
 

Have you tried connecting it with Ethernet cable to update? 
 

Is the rest of your system updated?

Have you tried powering it off, waiting a few minutes, and then restarting it?

I tried everything, my whole system is Ethernet cable connected. It picks up my soundbar and my 2 Sonos play 5 but not the Sub and the Booster. I still have my soundbar a Sonos play 5 working great. 

Whilst you’ve not answered all of my questions, you do say you’ve tried everything, so try speaking to Sonos support and see what they suggest. 

 Note: in general use, the Surrounds and the Sub connect to the soundbar across a ‘hidden’ 5 GHz signal, and don’t normally go through the router. You may want to try turning on the ‘radio’ on both your Sub and soundbar ( and frankly, the surrounds) and try your update again. 

Booster? Do you mean a Sonos Boost?

With all your speakers wired it isn't doing anything useful. Even with only some wired it is likely redundant.

Power down all Sonos, reboot router and controller, give it a minute to wake up and then power on the Sub then the soundbar, nothing else, then try the update.
