With AirPort Express, getting your new Wi‑Fi network up and running takes less time — and less effort — than making a cup of coffee. That’s because a setup assistant is built into iOS and into AirPort Utility for OS X. And if you use a Windows PC, you can download AirPort Utility for free. As soon as you plug in your AirPort Express Base Station and connect it to your DSL or cable modem, you can follow the simple instructions on your computer or iOS device. There are no complicated steps to follow and there’s no obscure terminology to learn. The setup assistant does all the work, so you don’t have to.
