Good evening. I have a few questions. Is this product connected via Ethernet cable and does it provide the Wi-Fi signal for the whole house by itself without having to connect another modem/router? In the sense that only with that can I operate TV, Apple TV, Amazon Fire sticks? Another question, with an outlet with a POE + Ethernet output adapter could I first power the device and with the Ethernet output I could supply the bandwidth to a device (e.g. APPLE TV)? Thank you very much
