My Sony tv has built in cromcast and is connect with Ethernet-cable. 

It gets ip 88.90.165

And my phone is on wifi from the same router, it get ip 192.168.86

And every time i want to cast from my phone i have to remove the ethernet-cable and conect tv on wifi for my phone to find it. 

How can i fix this?

Hello @Dnb91 

It sounds like your TV is connected to an "outer" Ethernet network – the same one your primary Nest WiFi Router unit's WAN Ethernet port is connected to. Since the Nest WiFi Router is a router+firewall, it creates a new "inner" network (the 192.168.86.x address space you see for your WiFi devices). But, you can use the LAN Ethernet port on the Nest WiFi Router to feed your home's Ethernet network, making all Ethernet-connected devices part of the same inner network as your WiFi devices. In this setup, your Nest WiFi Router's WAN port should be the only thing directly connected to the outer network. You may need to buy an inexpensive, unmanaged Ethernet switch to make more ports available to feed all of your existing Ethernet runs.

Ha ha.  That's a big poop you have to live with.  The wifi must have it's own IP address to dance around.  My network system is just the same with both ethernet for the tv and such, and the wifi.  You need to muck with the Nest router, and do port forwarding.  The hard part is find the API of the tv and such, and find the port numbers.  I interfaced the Hdhomerun for antenna signals, and the port numbers were hard to find.

This has been the advice from the very beginning.  Every telecom has a weird and wonderful router/modem.  The router has to be ruthless to punch down the telecom thing.  I have that with openwrt, but I would like to know the success rate of the built-in wifi router.  The experience of someone using Google Fiber leads me to doubts.  I find that all the main support on here are Sheldons, and all the customers are Pennys.
