I have a Sonos sub, sonos sound bar, play 3, play 5, and 5 sonos ones. Recently we had internet problems so someone came and made changes to the network which made it so none of the speakers were connected anymore. They were all previously on the same network. The speakers are at my parents vacation home and I set them all up so they don't know how to do it, but I wont be able to go reset them for a few months. My question is, can I Just take one of the speakers, plug it into an Ethernet and connect it to the new internet then all other speakers will automatically connect or do I have to do it individually. A lot of the speakers I have the wiring fished through the wall to avoid loose cables and are mounted, so I would hate to have to remove all of them. If there is a solution with a quick fix to put all of my speakers on to the new internet, please let me know.

Keeping things as simple as possible.. switch off every sonos device, plug in one play:1 to the (new) main router.
Switch on the sonos speakers one at a time. Initially each speaker will look for the old internet connection first of all, then it will connect to the Play: 1’s SonosNet wireless signal, it may take a while, so be very patient... do each speaker one at a time.
Make sure the sonos controller device is obviously attached to the same network.
When you later goto the vacation home, simply enter the new WiFi setup credentials (case sensitive) in the sonos App 'Advanced Settings/Wireless Setup' and after a few minutes you can disconnect the Play:1 from the router (if you want to) and all will then work on the 'new WiFi setup' from that point onward.
