AirPort is based on the latest Institute of Electrical and Electronics Engineers (IEEE) 802. 11n draft specification and provides fast and reliable wireless networking in the home, classroom, or small office. You can enjoy data transfer rates of up to five times faster than data rates provided by the 802. 11g standard and more than twice the network range. The AirPort Extreme Base Station and Time Capsule are dual-band, so they can work in either the 2. 4 gigahertz (GHz) or 5 GHz spectrum. And they are 100 percent backwardcompatible, so Mac computers and PCs that use 802. 11a, 802. 11b, 802. 11g, or IEEE draft specification 802. 11n wireless cards can connect to an AirPort wireless network.

If there is a device listed that you'd like to remove from the list, select it and click the Delete (­) button. Chapter 3 AirPort Network Designs 43 7 Click Update to send the new settings to the devices in the WDS. By default, the "Allow wireless clients" checkbox is selected. If you deselect the checkbox and later want to change the settings on the wireless device, you must connect to the device's LAN port with an Ethernet cable. To set up additional remote devices to connect to the main device: If you want to add additional remote or relay devices to the WDS after setting up the main and remote devices, use AirPort Utility again. Before setting up additional remote devices, find the channel of the main device in the Summary pane of AirPort settings in AirPort Utility. 1 Click the AirPort status menu in the menu bar and choose the wireless network created by the device you want to set up as a remote device. 2 Open AirPort Utility (in the Utilities folder in the Applications folder on a Macintosh computer, or in Start > All Programs > AirPort on a computer using Windows). Select the remote device, and choose Manual Setup from the Base Station menu. If the device is using the default password of public, you will not be prompted for a password. Choose "Participate in a WDS network" from the Wireless Mode pop-up menu, and choose the same channel as the device from the Channel pop-up menu. 5 Click WDS and choose "WDS remote" from the pop-up menu. 44 Chapter 3 AirPort Network Designs 6 Enter the MAC address of the main device in the WDS Main field. The MAC address is also referred to as the AirPort ID and is printed on the label on the bottom of the device. 7 Click Update to transfer the settings. By default, the "Allow wireless clients" checkbox is selected. If you deselect the checkbox and later want to change the settings on the wireless device, you must connect to the device's LAN port with an Ethernet cable. To set up a relay device to connect to the main device and share its connection with additional remote devices: If you want to set up a relay device in the WDS to share its connection with other remote devices and wireless clients, use AirPort Utility again. When you set up a relay, you also need to set up at least one additional remote to share the relay's connection. To set up a relay, first set it up as a remote by following the instructions on page 44. Chapter 3 AirPort Network Designs 45 Relay and remote devices need to be on the same channel as the main device. Before setting up a relay or remote device, find the channel of the main device in the Summary pane of AirPort settings in AirPort Utility. 1 Click the AirPort status menu in the menu bar to join the wireless network created by the wireless device you want to set up as the relay device. 2 Open AirPort Utility (in the Utilities folder in the Applications folder on a Macintosh computer, or in Start > All Programs > AirPort on a computer using Windows).
