WPA and WPA2 Personal

For home or Small Office/Home Office (SOHO) networks, WPA and WPA2 runs in Personal mode, taking into account that the typical household or small office does not have an authentication server. Instead of authenticating with a RADIUS server, users manually enter a password to log in to the wireless network. When a user enters the password correctly, the wireless device starts the encryption process using TKIP or AES-CCMP. TKIP or AES-CCMP take the original password and derive encryption keys mathematically from the network password. The encryption key is regularly changed and rotated so that the same encryption key is never used twice. Other than entering the network password, the user isnt required to do anything to make WPA or WPA2 Personal work in the home.

WPA and WPA2 Enterprise

WPA is a subset of the draft IEEE 802.11i standard and effectively addresses the wireless local area network (WLAN) security requirements for the enterprise. WPA2 is a full implementation of the ratified IEEE 802.11i standard. In an enterprise with IT resources, WPA should be used in conjunction with an authentication server such as RADIUS to provide centralized access control and management. With this implementation in place, the need for add-on solutions such as virtual private networks (VPNs) may be eliminated, at least for securing wireless connections in a network. For more information about setting up a WPA or WPA2 protected network, see Using Wi-Fi Protected Access on page 50.

AirPort Network Designs

This chapter provides overview information and instructions for the types of AirPort Extreme networks you can set up, and some of the advanced options of AirPort Extreme.
Use this chapter to design and set up your AirPort Extreme network. Configuring your Apple wireless device to implement a network design requires three steps: Step 1: Setting Up the AirPort Extreme Network Computers communicate with the wireless device over the AirPort wireless network. When you set up the AirPort network created by the wireless device, you can name the wireless network, assign a password that will be needed to join the wireless network, and set other options. Step 2: Configuring and Sharing Internet Access When computers access the Internet through the AirPort Extreme network, the wireless device connects to the Internet and transmits information to the computers over the AirPort Extreme network. You provide the wireless device with settings appropriate for your ISP and configure how the device shares this connection with other computers. Step 3: Setting Advanced Options These settings are optional for most users. They include using the Apple wireless device as a bridge between your AirPort Extreme network and an Ethernet network, setting advanced security options, setting up a Wireless Distribution System (WDS) to extend the AirPort network to other wireless devices, and fine-tuning other settings. For specific instructions on all these steps, refer to the sections later in this chapter. You can do most of your setup and configuration tasks using AirPort Utility, and following the onscreen instructions to enter your ISP and network information. To set advanced options, you need to use AirPort Utility to manually set up your Apple wireless device and AirPort network.

Using AirPort Utility

To set up and configure your computer or Apple wireless device to use AirPort Extreme for basic wireless networking and Internet access, use AirPort Utility and answer a series of questions about your Internet settings and how you would like to set up your network. 1 Open AirPort Utility, located in the Utilities folder in the Applications folder on a Mac, or in Start > All Programs > AirPort on a Windows computer.
2 Select your device in the list on the left if there is more than one device in your network. Click Continue, and then follow the onscreen instructions to enter the settings from your ISP or network administrator for the type of network you want to set up. See the network diagrams later in this chapter for the types of networks you can set up using AirPort Utility. To set up a more complicated network, or to make adjustments to a network you have already set up, use the manual setup features in AirPort Utility. Setting AirPort preferences Use AirPort preferences to set up your wireless device to alert you when there are updates available for your device. You can also set it up to notify you if there are problems detected, and to provide instructions to help solve the problems. To set AirPort preferences: 1 Open AirPort Utility, located in the Utilities folder inside the Applications folder on a Mac, and in Start > All Programs > AirPort on a Windows computer. 2 Choose Preferences from the AirPort Utility menu on a Mac, and from the File menu on a Windows computer.
Chapter 3 AirPort Network Designs
Select from the following checkboxes: Select Check for Updates when opening AirPort Utility to automatically check the Apple website for software and firmware updates each time you open AirPort Utility. Select the Check for updates checkbox, and then choose a time interval from the pop-up menu, such as weekly, to check for software and firmware updates in the background. AirPort Utility opens if updates are available. Select Monitor Apple wireless devices for problems to investigate problems that may cause the device's status light to blink amber. With the checkbox selected, AirPort Utility opens if a problem is detected, and then provides instructions to help resolve the problem. This option monitors all of the wireless devices on the network. Select Only Apple wireless devices that I have configured to monitor only the devices you have set up using this computer. Monitoring devices for problems requires an AirPort wireless device that supports firmware version 7.0 or later. To set up your wireless device manually: 1 Open AirPort Utility, located in the Utilities folder in the Applications folder on a Mac, or in Start > All Programs > AirPort on a Windows computer. 2 Select your device in the list. 3 Choose Manual Setup from the Base Station menu and enter the password if necessary. The default device password is public. If you dont see your wireless device in the list: 1 Open the AirPort status menu in the menu bar on a Mac and make sure that you have joined the AirPort network created by your wireless device. On a Windows computer, hover the cursor over the wireless network icon in the status tray to make sure the computer is connected to the correct network. The default network name for an Apple wireless device is AirPort Network XXXXXX, where XXXXXX is replaced with the last six digits of the AirPort ID, (or MAC address). The AirPort ID is printed on the bottom of Apple wireless devices. 2 Make sure your computers network and TCP/IP settings are configured properly. On a computer using Mac OS X, choose AirPort from the Show pop-up menu in the Network pane of System Preferences. Then choose Using DHCP from the Configure IPv4 pop-up menu in the TCP/IP pane. On a computer using Windows, right-click the wireless connection icon that displays the AirPort network, and choose Status. Click Properties, select Internet Protocol (TCP/IP), and then click Properties. Make sure Obtain an IP address automatically is selected. If you cant open the wireless device settings: 1 Make sure your network and TCP/IP settings are configured properly.

Using the wireless device as a bridge can be a way to address incompatibilities between the devices Internet sharing features and your ISPs connection method. Setting DHCP and NAT Options If you chose Share a public IP address from the Connection Sharing pop-up menu, you can set DHCP and NAT options. Click DHCP.
Choose a range of IP addresses from the DHCP Range pop-up menu. Choose 10.0, 192.168, or 172.16 and then enter a beginning and ending address in the DHCP Beginning Address and the DHCP Ending Address fields, depending on which addresses you want the wireless device to provide. Enter a number in the DHCP Lease field, and then choose minutes, hours, or days from the pop-up menu. Type a welcome message in the DHCP Message field. This message is displayed when a computer joins your network. If your network is set up to use a Lightweight Directory Access Protocol (LDAP) server on your network, you can enter the address of the server in the LDAP Server field, and computers on your network will have access to it. To provide specific IP addresses to specific computers on your wireless network, click the Add (+) button below the DHCP Reservations list, and follow the onscreen instructions to name the reservation and reserve the address by MAC address or DHCP client ID. If you choose MAC address, click Continue and enter the MAC address and specific IP address.
Next you can set NAT options for the network. Click NAT.
You can set up a default on your network. A default host (sometimes known as a DMZ) is a computer on your network that is exposed to the Internet and receives all inbound traffic. A default host may be useful if you use a computer on your AirPort network to play network games, or want to route all Internet traffic through a single computer. You can set up NAT Port Mapping Protocol (NAT-PMP). NAT-PMP is an Internet Engineering Task Force Internet Draft, an alternative to the more common Universal Plug and Play (UPnP) protocol implemented in many network address translation (NAT) routers. NAT-PMP allows a computer in a private network (behind a NAT router) to automatically configure the router to allow parties outside the private network to contact this computer. Included in the protocol is a method for retrieving the public IP address of a NAT gateway, allowing a client to make this public IP address and port number known to peers that may wish to communicate with it. This protocol is implemented in current Apple products, including Mac OS X 10.4 Tiger, AirPort Extreme and AirPort Express networking products, and Bonjour for Windows. You can also set up port mapping. To ensure that requests are properly routed to your web, AppleShare, or FTP server, or a specific computer on your network, you need to establish a permanent IP address for the server or computer, and provide inbound port mapping information to the Apple wireless device. See Directing Network Traffic to a Specific Computer on Your Network (Port Mapping) on page 54.

Setting DHCP Only Options If you chose Distribute a range of IP addresses from the Connection Sharing pop-up menu, your wireless device is set up to use DHCP to distribute a range of IP addresses using only DHCP. You cannot use NAT if you chose this option. Click DHCP and enter the beginning and ending addresses you want to distribute to computers joining your wireless network. You can set the additional DHCP options, such as DHCP Lease, DHCP Message, and other options following the instructions above. Setting Up Client Computers To configure TCP/IP on client computers using Mac OS X v10.5: 1 Open System Preferences on the client computer and then click Network. 2 Do one of the following: a If the client computer is using AirPort, select AirPort in the network connection services list, and then click Advanced.
Next, choose DHCP from the Configure IPv4 pop-up menu.
b If you enabled a DHCP server when you set up the wireless devices network, and the client computer is using Ethernet, select Ethernet in the network connection services list, and then choose Using DHCP from the Configure pop-up menu.
c If you selected Distribute a range of IP addresses when you set up the wireless devices network, you can provide Internet access to client computers using Ethernet by setting the client IP addresses manually. Select Ethernet in the network connection services list, and then choose Manually from the Configure pop-up menu.
Enter the IP and router addresses from the range your device is providing. Enter the DNS and Search Domain addresses if necessary.
When you configure Ethernet clients manually for a wireless device that provides NAT over Ethernet, you can use IP addresses in the range 10.0.1.2 to 10.0.1.200. In the Subnet Mask field, enter 255.255.255.0. In the Router field, enter 10.0.1.1. Enter the same name server address and search domain information that you entered in the wireless device configuration. To configure TCP/IP on client computers using Windows Make sure you have installed the wireless adapter in your computer and the software necessary to set up the adapter. To configure TCP/IP on client computers: 1 Open Control Panel from the Start menu, and then click Network and Internet. 2 Click Network and Sharing Center. 3 Click Manage network connections in the Tasks list. 4 Right-click the wireless connection you want to share, and then select Properties.
5 Click Internet Protocol Version 4 (TCP/IPv4), and then click Properties. If you chose Share a public IP address in the Network pane of AirPort Utility, select Obtain an IP address automatically.
If you chose Distribute a range of IP addresses when you set up the wireless devices network, you can provide Internet access to client computers by setting the client IP addresses manually. Select Use the following IP address.

Contact your network administrator for the information you should enter in these fields.
If you have already used AirPort Utility to set up your Apple wireless device, the fields below the Configure IPv4 pop-up menu may already contain the appropriate information.
If your IP address is provided by DHCP, choose Using DHCP from the Configure IPv4 pop-up menu.
5 Choose Off (Bridge Mode) from the Connection Sharing pop-up menu. Your wireless device bridges the Ethernet networks Internet connection to computers connected to the device wirelessly or by Ethernet. See Setting Up Client Computers on page 32 for information about how to set up client computers to connect to the Ethernet network.
Connecting Additional Devices to Your AirPort Extreme Network
Connect a USB printer to the USB port of your Apple wireless device (in this example, a Time Capsule) and everyone on the network can print to it. Connect a USB hub to the USB port of an AirPort Extreme Base Station or a Time Capsule, and then connect a hard disk and a printer so everyone on the network can access them. If you connect a Time Capsule, you can use Time Machine in Mac OS X Leopard (v10.5.2 or later) to back up all of the Mac OS X Leopard computers on the network. What It Looks Like

Connecting Additional Wireless Devices to Your AirPort Network

You can connect additional Apple wireless devices to extend the range of your wireless network. For example, you can connect an AirPort Extreme Base Station or a Time Capsule using Ethernet. A network with devices connected using Ethernet is known as a roaming network. You can also connect Apple wireless devices wirelessly. Connecting devices wirelessly creates what is known as a Wireless Distribution System (WDS). Setting Up Roaming Several AirPort Extreme Base Stations or Time Capsules can be set up to create a single wireless network. Client computers using AirPort can move from device to device with no interruption in service (a process known as roaming). To set up roaming: 1 Connect all of the AirPort Extreme Base Stations and Time Capsules to the same subnet on your Ethernet network. 2 Give each device a unique name.
3 Give each device the same network name and password. 4 Set up the devices as bridges, following the instructions in the previous section. If you want one device to assign IP addresses using DHCP, also do the following: 1 Set up one device to act as the DHCP server. 2 Set up the other devices as bridges, following the instructions in the previous section. The device acting as a DHCP server can also receive its IP address via DHCP from a server on an Ethernet network or from a cable or DSL modem connected to an Internet service provider (ISP).

Setting Up a Wireless Distribution System (WDS)
When you connect devices wirelessly in a WDS, you set up each device as either a main, a remote, or a relay device. You can connect AirPort Extreme 802.11n Base Stations or Time Capsules and use the 5 GHz frequency band in the network. Only client computers that have 802.11n wireless cards installed can join the network. If you want client computers using 802.11b or 802.11g wireless cards to join the network, set up the network using the 2.4 GHz frequency band, or add 802.11g AirPort Extreme or AirPort Express to the network. See Choosing the Radio Mode on page 21 for information about setting the frequency band of the network. You can also set up a dual-band network that utilizes both the 2.4 GHz and 5 GHz frequency bands, so client computers using 802.11n wireless cards can join the 5 GHz segment of the network, and computers using 802.11b or 802.11g wireless cards can join the 2.4 GHz segment. See Setting up a Dual-Band (2.4 GHz and 5 GHz) Network on page 48.
AirPort Extreme DSL or cable modem
A main wireless device is connected to the Internet and shares its connection with remote and relay devices. A remote device shares the main devices Internet connection. A relay device shares the main devices Internet connection and transfers the connection to other remote or relay devices. All three device configurations (main, remote, and relay) can also share the main devices Internet connection with client computers wirelessly, or using Ethernet if the client computers are connected to the device by Ethernet. When you set up wireless devices in a WDS, you need to know the AirPort ID of each device. The AirPort ID is also known as the MAC address. To make it easier to set up a WDS, place all of the devices on a table and plug them into a power supply. As part of the WDS setup process, you might consider giving all the devices unique names, to make them easier to identify in the future.

To set up the main wireless device to share its Internet connection with other wireless devices: 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 the main device. 2 Open AirPort Utility (located in the Utilities folder in the Applications folder on a Mac, or in Start > All Programs > AirPort on a Windows computer).

Behind the Scenes

This chapter defines terms and concepts used to discuss computer networks. Use it as a reference to help you understand what is taking place behind the scenes of your AirPort wireless network. Basic Networking
Packets and Traffic Information travels across a network in chunks called packets. Each packet has a header that tells where the packet is from and where its going, like the address on the envelope when you send a letter. The flow of all these packets on the network is called traffic.
How Information Reaches Its Destination
Hardware Addresses Your computer listens to all of the traffic on its local network and selects the packets that belong to it by checking for its hardware address (also called the media access control, or MAC address) in the packet header. This address is a number unique to your computer. Every hardware product used for networking is required to have a unique hardware address permanently embedded in it. Your AirPort Cards number is called the AirPort ID. IP Addresses Since the Internet is a network of networks (connecting millions of computers), hardware addresses alone are not enough to deliver information on the Internet. It would be impossible for your computer to find its packets in all the worlds network traffic, and impossible for the Internet to move all traffic to every network.
So, your computer also has an Internet Protocol (IP) address that defines exactly where and in what network its located. IP addresses ensure that your local Ethernet network receives only the traffic intended for it. Like the hierarchical system used to define zip codes, street names, and street numbers, IP addresses are created according to a set of rules, and their assignment is carefully administered.
