General
Creating a Wi-Fi network or expanding your current network is a cinch with the Apple AirPort Express! The AirPort Express is also a great way to stream music from your iTunes library to your stereo system, and you can even use it for wireless printing via the USB connector on the back, so it's like having a printer in every room. You'll find that the AirPort Express features built-in firewall as well, so your network is well protected against viruses and the like; the firewall turns on automatically.
Configuration
There's an automatic configuration assistant built into your Apple device's iOS operating system that will help you through the configuration process. Do you have Windows? No problem, because the configuration program is available as a free download, so you can get going as soon as you connect your airport Express to your ADSL or cable modem. Once your Wi-Fi network is set up it's easy to manage, and if applicable, a comprehensive overview of your AirPort base stations is also at your disposal. This makes it quick and easy to install updates and make modifications.
