Agree. I have a Samsung TV in a bedroom where the built-in apps stopped updating due to the Samsung’s limited memory. It affected my ability to control the Samsung’s settings. Fix required a call to support. I don’t have time for that. Afterwards, I removed all the apps I had installed on the Samsung and got an ATV.

You can pick between networks in the ATVs settings. That may be a way of doing it if your WiFi and Ethernet connections present themselves as different networks.
