This answer is not helpful and Apple is not properly maintaining this software. The Apple TV software as well as all the help assume you are connecting the Apple TV with Wi-Fi. This is silly as all Apple TVs have RJ45 connectors making it possible to connect the Apple TV via an ethernet cable. Exactly what I do. Apple should fix this software to not search via WiFi to connect, but to search on the same LAN, regardless whether any connection is done via Wi-Fi or not. In my case I want to run the app from my iPad, connected via WiFi, but going of course to the router, which connects to the Apple TV via cable. The make the connection is always a hassle. Awful that Apple cannot make software that matches its hardware.
