Check with your ISP for instructions on getting connected.
• If you connect to the Internet by dialup modem: Connect the
telephone line to the phone line port on the Base Station.
• If you connect to the Internet by DSL or cable modem: Use an
Ethernet cable to connect the modem to the Base Station™s WAN
port.

5. Select the Set Up an AirPort Base Station radio button and then click
the Continue button in the lower-right corner of the window.
If your computer is in range of only your one wireless network, the Setup
Assistant automatically configures your AirPort Card to select that net-
work and proceeds to the America Online Access panel. However, if you
happen to be in range of more than one wireless network, you see the
Select an AirPort Network panel that asks you to select your network
from a pop-up list. Your network will have the name assigned at the fac-
tory, similar to Apple Network xxxxxx where xxxxxx is a six-digit hexa-
decimal number. After selecting your network, click the Continue button
to go to the next panel.
6. In the America Online Access panel:
• If you connect to the Internet via AOL: Select the I Am Using
American Online radio button and then click the Continue button.
• If you™re not using AOL: Select the I Am Using Another Internet
Service Provider radio button and then click the Continue button
to display the Internet Access panel.

7. In the Internet Access panel, choose one of the following options and
then click the Continue button:
• Telephone Modem: Select this radio button if you connect to the
Internet through a dialup modem. The AirPort Base Station is one
of the few wireless access points that includes a 56 Kbps modem.
By choosing this option, all the computers connected to your wire-
less network might be able to share a single dialup connection.
If you have one of the new Airport Extreme Base Stations, you might not
have a built-in version. There are two versions, and the less expensive
one does not have a modem.
• Local Area Network: You should select this radio button if your
computer is connected to a high-speed LAN.
• Cable Modem or DSL Using Static IP or DHCP: Select this radio
button if you connect to the Internet by cable modem or by DSL
but only if your ISP doesn™t use the PPP over Ethernet (PPPoE)
protocol.
• Cable Modem or DSL Using PPPoE: If your ISP uses the PPPoE
protocol, select this radio button. It is important that you make a
successful connection to the Internet with your computer con-
nected directly to the cable or DSL modem before attempting to
configure the Base Station. The AirPort Setup Assistant will then be
able to copy the PPPoE settings from your computer to the Base
Station so that the Base Station can log on to the Internet with your
user ID and password. All the computers on your wireless network
will then be able to share the Internet connection without needing
to log on.
The next panel that you see at this step depends on the choice that you
make in Step 7:
• Telephone Modem: If you choose Telephone Modem, you see the
Modem Access panel with text boxes available for various dialup
parameters such as user name, password, and phone number. In
most cases, the setup assistant copies this information from your
computer.
• LAN, or Broadband Using Static IP or DHCP: If you choose either a
LAN or a broadband (cable modem or DSL) connection that doesn™t
use PPPoE, the Ethernet Access panel presents the option to use
DHCP or to assign a static IP address. If your ISP has assigned you
a static IP address ” along with other values such as subnet mask,
router address, domain name, and/or DHCP client name ” you
have to enter this data if it isn™t automatically copied from your
computer.
158 Part III: Installing a Wireless Network

• Broadband Using PPPoE: If you select the Cable Modem or DSL
Using PPPoE option, the PPPoE Access panel presents text boxes
for entering an account name, password, and other account infor-
mation sometimes required by PPPoE providers. Again, in most
cases, this information is automatically copied from your computer.
After you enter the appropriate information, click the Continue button to
display the Network Name and Password panel.
8. In the Network Name and Password panel that appears, enter the
name and password that you want to use for your wireless network
and then click the Continue button to display the Base Station
Password panel.
The Base Station Password panel gives you the options to use the net-
work password as your Base Station password or to assign a different
password for changing the settings on your Base Station. If you™re the
only person who™ll be configuring the computers on the network, using
the same one both places is probably the easiest. However, if you plan to
share the network password with other users, assign a different pass-
word to the Base Station so that only you can change the Base Station™s
settings.
9. Click the Continue button to display the Conclusion panel.
The Conclusion panel informs you that the Setup Assistant is ready to
set up your Base Station.
10. Click the Continue button.
After the Setup Assistant downloads the new settings to the Base
Station, it displays a message that it™s waiting for the Base Station to
reset. As soon as the Base Station resets, the Setup Assistant displays a
panel announcing that it™s finished and that it has been able to configure
this computer to connect to the Internet.
11. Click the Done button to close the AirPort Setup Assistant.



Adding another computer to your
AirPort network on OS X
When you set up your AirPort Base Station by following the directions in the
preceding section (“Configuring the AirPort Base Station on OS X”), you also
set up the AirPort Card in the computer that you used to configure the Base
Station. However, you need to configure the AirPort Cards in the other Mac
computers in your house to enable them to connect to the AirPort network.
Follow these steps:

If your AirPort Base Station is the only wireless network within range,
the next panel will prompt you to enter the network password. However,
if you happen to live close enough to neighbors who also have a wireless
network, you might see the network name of that neighbor™s network.
5. Select your network name from the pop-up list and then click the
Continue button to display the Enter Network Password panel.
6. Type the network password for your wireless network in the
Password text box and then click the Continue button to display the

click the Done button.
The assistant closes itself.




Adding a Non-Apple Computer to
Your AirPort Network
One of the reasons why wireless home networking has become so popular is
the interoperability between wireless networking equipment from different
vendors. Apple wireless networking equipment is no exception. You can even
use a Windows or Linux computer to connect to an Apple AirPort Base Station.

The procedure for entering the wireless network parameters in non-Apple
wireless software for configuring a wireless network adapter varies by manu-
facturer. Follow these general steps to add your non-Apple computer (or even
Apple computer with non-Apple wireless hardware and software) to your
AirPort Network:
160 Part III: Installing a Wireless Network

1. Select the network name of the AirPort Base Station.
The wireless network adapter configuration software will usually present
a list of available wireless networks in range of the adapter. Select the
network name that you assigned to the AirPort Base Station from the list.
For example, in Windows XP, right-click the Network icon in the notifica-
tion area of the task bar and then select View Available Wireless
Networks from the pop-up menu that appears. Then select the AirPort
Base Stations network name from the list presented in the Wireless
Network Connection dialog box.
2. Enter the network password.
The password that you entered in the AirPort Base Station setup proba-
bly won™t work. Here™s how to find the password ” the WEP key ” that
will work. Apple uses a different password naming convention than
other wireless manufacturers. Fortunately, Apple has provided the
AirPort Admin Utility that does the conversion for you:
a. Open the AirPort Admin Utility.
b. Select your Base Station from the list and then click the
Configure icon.
c. When presented with a pop-up window, enter the password for
configuring the base station and then click the OK button to dis-
play the main AirPort Admin Utility window.
d. If you™re using OS X, click the Password icon in the toolbar at the
top of the window.
Note: If the toolbar isn™t visible, click the View menu and choose
Show Toolbar.
The utility opens a drop-down window that displays the equivalent
network password (WEP key) that you should enter in the configu-
ration software for your non-Apple wireless network adapter.
e. If you™re using OS 9, choose Equivalent Network Password from
the Base Station menu.
A pop-up window appears with the equivalent network password
(WEP key) that you should enter in the configuration software for
your non-Apple wireless network adapter.
3. Make sure that you set the adapter to obtain an IP address
automatically.
How you do this depends on what kind of PC and which PC operating
system you™re using.
4. Close the configuration software, and you should be connected to the
AirPort network.
If you™re not connected, go through the steps again, paying particular
attention that you enter the equivalent network password correctly.

Chapter 8: Setting Up a Wireless Mac Network

If you™re really having a hard time, try turning WEP off on your AirPort
Base Station (deselect the Use Encryption check box in the Airport
Setup Program) and see whether you can connect without any encryp-
tion. If this works, double-check your Equivalent Network Password and
look in the manual for your network adapter. You might need to enter a
special code before the Equivalent Network Password ” we discuss this
in Chapter 10.



Connecting to Non-Apple-Based
Wireless Networks
One scenario that you might encounter in a home network is the need to con-
nect a Macintosh computer to a non-Apple-based network. Follow the proce-
dures outlined in this chapter for adding a computer to a wireless network. If
you have any trouble, it will almost certainly relate to the network password.
Here are a few troubleshooting tips to resolve password issues:

Try turning off encryption on the wireless network. If you can suc-
cessfully connect your Mac to the network without the need of a pass-
word, you can be sure that the password was the problem. Don™t leave
the network unprotected, however. Read on.
Check the password configuration. When you turn on the access
point™s encryption, determine whether the password is an alphanumeric
value or a hexadecimal number. Some hardware vendors provide config-
uration software that has you enter a pass phrase, but the software then
generates a hexadecimal number. You have to enter the hexadecimal
number in the AirPort software, not the pass phrase.
Watch for case-sensitivity. If the Windows-based access point configura-
tion software enables you to enter an alphanumeric password, keep in
mind that the password is case sensitive. The password should be either
exactly 5 characters (letters and/or numbers) for 64-bit encryption or 13
characters for 128-bit encryption. You should then enter exactly the
same characters in the Password text box in the AirPort configuration
software.
Use current software. Make sure that you™re using the most current ver-
sion of AirPort software. The most up-to-date software makes it easier to
enter passwords connecting to a Windows-based wireless network. The
new software automatically distinguishes between alphanumeric and
hexadecimal passwords. With earlier versions of the software, to con-
nect to a WEP-encrypted Windows-based network, you have to type quo-
tation marks around alphanumeric values and type a $ in front of
hexadecimal numbers.
162 Part III: Installing a Wireless Network

These guidelines should help you get your Mac connected to a Windows
wireless network, including the capability to share the Internet. Keep in mind,
however, that other factors determine whether you can also share files, print-
ers, and other resources over the wireless network. Mac OS X is generally
more PC friendly than Mac OS 9, but OS 9-based utility software such as the
DAVE software from Thursby Software Systems (www.thursby.com) is avail-
able that enables you to add your Mac to a Windows network to share files
and printers.
