I have a play 3 and play 5, one upstairs on the second floor and the other on the ground floor. The original setup had both speakers connected to my router (upstairs). This setup was working ok, the only problem being that my phone (device always used to control Sonos) looses the wifi signal when on the ground floor.
To remedy this I have a second wifi access point connected over Ethernet back to the router. I can now get access to wifi throughout the home. Problem is when I'm downstairs I can't see the Sonos speakers as they're on the upstairs original network.
Can anyone point me in the right direction for a setup where I can connect to both networks but still see the Sonos speakers?
