SonosRadio?

Your devices have probably just lost their DHCP assigned IP addresses. You may find powering off your router (or DHCP server device) for a minute or so and then powering it back on and waiting for a few minutes will quickly sort it for you.

Nope.  

The Boost is appearing on the network - but Beam is missing.  Tried to Add but the stupid controller app can’t find it.

An utter mess

Strange🤔?. The recent update went okay here, but there again, I do have my Sonos IP addresses reserved, so it’s rare I lose them during restart, post update.
 

Have you tried switching your DHCP server ‘off’ and then ‘on’ again? Also, if it’s now been a while your device(s) might have fallen back to Auto-IP mode (169.254.xx.xx) and perhaps just in need of a quick reboot to get them back up and running on your network. 

hi Ken

Thanks for the advice.   Got things back on track by simply unplugging the Beam …. absolutely no idea what went wrong.  

It wasn’t until I’d installed the Sonos Radio that I then read it is ad-supported.  I don’t think it’ll last long on my system if that’s true!

I read this, but I’ve yet to encounter an ad. It’s very strange, you just get a ‘you’re listening to Sonos [whatever]’ every few songs but maybe it’s because it’s a new service and ads will start appearing as advertisers come on board. The flagship ‘Sound System’ station does say it’s ad free though. 
 

But why do we need the grating “you’re listening to Sonos” “make your ears bleed” nonsense? Unless that goes, it’s going. 

It doesn’t bother me too much, maybe because I don’t listen to it that often… just when Mary Anne Hobbs is on 6 Music
