First off are you using a wired or wireless network? I.E. is everything plugged in with Ethernet or not?
If it is *wired*
If you are using a wired network this is almost certainly because the router IP address has changed from say 192.168.0.1 to 22.214.171.124 or something similar. Usually simply power cycling the Sonos will solve this.
If it is *wireless*
With Sonos the best thing to do is to plug one single unit directly in with an Ethernet cable directly to the router and obvs main power. You should then be able to update the wi-fi credentials
Settings -> system -> system settings -> network -> wireless setup
If the Sonos boxes are within range of each other they can chat amongst themselves and propagate the new credentials.
The other way of achieving this is to change the network name and password on the router to the old network name and password. This is usually the easiest way.
However, this may not work if devices are checking the MAC address of the router to prevent spoofing or if you have set MAC + IP to BIND to increase network security.
We have this problem constantly with clients who rent out houses and don’t rent it out with the broadband. The renter then changes the router and nothing works…..again and again and again……it is even worse with smart homes where everything is chatting to the network and everything needs new network credentials!
Really installers should ask if you want to map your old network credentials over - provided they are secure.
