I'm hoping someone can give me a hand with this query. I've dug out an older model Airport Express and i'm hoping to put it back into use, but my stereo is in a separate room to my wifi modem. In fact - separate ends of the house. The setup directions i've seen online seem to say I need to have the Airport Express plugged into the wifi modem via ethernet cable, but i'm thinking that considering it is wifi capable (or something) maybe there's a way I can have it connected to my stereo in the back room, connecting to the wifi from the front room. Is that possible? Thanks!
