Take Control of Your 802.11n AirPort Network, 3rd Edition (Repost)

If you’re trying to solve a particular problem, you can jump in and read the topics in this ebook in any order, but if you start at the beginning, you’ll learn how Apple’s 802.11n gear fits into the world of Wi-Fi networking.

With that background, you’ll learn where to position and how to set up base stations, with diagrams showing common network scenarios – see two examples above – and with step-by-step instructions for configuring key Internet sharing and security options and connecting client computers. For those who have funky Internet connections or tricky IP addressing needs, Glenn provides extended advice for creating a working Wi-Fi network.

Glenn provides real-world directions for important scenarios, including how to:

Create a basic (or not so basic) Wi-Fi network, using Apple’s base stations:
Set up a wireless network with a single base station, or with multiple base stations – whether you want to extend a network with Ethernet or a wireless connection (or a mix of the two), Glenn examines your options and provides configuration steps. He also touches briefly on powerline connections.
Keep your existing network, but replace an older or broken base station with a new one.
Export your base station’s configuration, either to make a backup or to create a model configuration to use on other base stations.
Connect Macs (specific steps for 10.5 Leopard and later), iOS devices, and Windows 7 computers to your network.
Set up reliable and relevant security for your network. Also, add a guest network that gives your guests Internet access while restricting their access to local resources.
