I have a Chromecast and Apple TV connected to a Phillips TV through the HDMI ports. The Wi-Fi router is on another room on the same floor. The devices are Android phone and iPad Mini.
I was able to setup the Chromecast but can't broadcast anything. The Apple TV is able to connect to the iPad but not always I'm able to connect it and when I do it, after few minutes the connection is lost.
My router is a single band router. I don't know where start looking first but I think that I should start looking on the router settings. How do I establish a reliable connection?
