It looks like the nest wifi creates a new subnet under 192.168.86.x. This is different from my wired network so I can't access any devices from my wired computers. I would like to change the LAN IP to match my wired network. Every time I go into advanced settings and change it, it will revert back. What am I doing wrong here?
There are 3 routes you can take.
1. Put the nest in AP mode. This will prevent it from being in a mesh.
2. Get a switch and use the ethernet out and hook switch to it instead of using ISP equipment for ethernet.
3. Get a different mesh system such as UniFi that will do what you are currently trying to do.
