Hi I've just got a new wireless network and my Apple TV is not connected to it, error message when I go to tv channel for Apple TV. Error telling me to go to settings etc and connect which is fine. Issue is I have no physical remote and I had the remote app downloaded but it is not connecting to Apple TV, keeps prompting for. Home sharing which I have/had already activated but won't allow me to interact with Apple TV .. How do I get Apple TV connected to new network and get remote working??
