I've bought an AirPort Express plug in gadget.I mainly want to use the music from my or the kids iPhones to play music on the surround system wirelessly.The side bonus was that it states you can connect a printer. I've plugged it in but have not connected the internet box/connection as thats in the garage and not next to the surround system in the lounge. The unit is now flashing amber.Is it essential that the gadget is connected to the internet box in the garage? I maybe wrong but does this box create another wireless network in addition to the one that the BT box gives out? We already have all out laptops(4) xbox and playstation configured to be used on the BT box no problem. I only want a stereo output really. This looks like a time vampire unless you guys can tell me different? Heeeeelp.
