Chromecast when using wired LAN network

[paulzz3000]

When connected via ethernet I cannot also connect via wi-fi so how do I use the built in Chromecast on my XG9005?

It's while since I setup my XF but it should be available in Google home once you've setup the TV.  You'd need to connect in Google Home before casting, and there are other things like location that have to be turned on, which could different lan vs WiFi.
