Sonos Play 1 Discovery Issues

Hello @David_Parker,

Thanks for contacting support, can you please let me know how your Sonos devices are connected to the network here? Are you connecting them via Ethernet or WiFi? Have you made sure that your Sonos devices are on the same networking segment? As in if you are making use of multiple VLANs, I would make sure that everything is on the same VLAN and IP Address Subnet range.

Please also provide some more information regarding your setup using this link as a guide:

Thanks,
Noris
