Hi, I have been using Sonos for over 15 years, was an early adopter. I have 3 Sonos Ones unit connected to my Sonos S1 App and they work fine. I have had an old ZP80 and ZP100 connected together to a S2 App. The latter used to work fine, and as I have changed my router it stopped working. If I wire it to the router it temporary works. Once ethernet cable unplugged it disconnects.
Can you please help?
Many thanks!
