Sonos SUB - Network and Support; Router or Network Password Changes

SONOS USER GUIDE
Have a new router or network password?
If you have a wireless setup (no Sonos product connected to your router):
After you install a new router or change your network password, update your Sonos system with the new
network information. Just open the Sonos app and we’ll walk you through it.
If you have a wired setup (there’s a Sonos product connected to your router):
You don’t have to do anything when you install a new router (as long as you connect a Sonos product to it) or
when you change your password. Your Sonos products will continue to work as before.
