1. Can I use it for AirPlay and Wi-Fi at the same time 2. Can I make it wort as an extension of sorts, connect to my existing wifi network and link a second network through that 3. While using AirPlay, can I use any 3.5mm connector, such as a stereo connector meant for mp3 players, or my headphones? I apologize if the answers are easily found elsewhere, but I couldn't find them.
