Hi @dhaugen.
Thanks for the update and immediate response.
Since you have mentioned about Google Mesh system. Allow me to share with you some information to help out. You don’t even need to do my recommendation above. What you are experiencing is doubleNAT. where if your mobile phone transfers connection from one Access point/node to another node, it cannot see the devices connected to the access point/node it came from. I would suggest reaching out to the manufacturer of the mesh system so that the mesh system can be configured in bridge mode or access point mode or which option best fits your preference (the main objective is to disable the mesh from generating their own IP-address).
- Have each access point have their own unique Wi-Fi name as so you and your mobile controller do not get confused about what and where to connect to access your Sonos system.
- Disable Wifi Capabilities of the Main router that provides connection directly to your ISP or internet provider.
- Disable the DHCP or IP-address generation of the Access point and only allow the main router to generate the IP-addresses to avoid IP-address mismatch or IP-address duplicates.
- Wire a Sonos device to one of the routers/access points to get them to stay on a single network (having each access point have their own unique WiFi names).
Let me share with you a topic in this community that discusses multiple routers. You can share and ask questions or comments on that topic if something is not clear.
I hope this helps.
Please let me know if you have further questions or concerns. I’ll be more than happy to help you out.
Thanks,
