key — in OS X, this is in the Base Station menu.)
For WEP, the built-in wireless LAN client software in Windows XP numbers
its four keys from 0–3 rather than 1–4. So, if you’re using Key 1 on
your access point, select Key 0 in Windows XP.

You have finished turning on WPA or WEP. Congratulations.
Can we repeat ourselves again? Will you indulge us? The preceding steps are
very generic. Yours may vary slightly (or, in rare cases, significantly). Read
your user’s guide. It tells you what to do.
After you configure WPA or WEP on the access point, you must go to each
computer on your network, get into the network adapter’s client software (as
we describe in Chapters 7 and 8), turn on WEP, and enter the passphrase or
the WEP key. Typically, you find an Enable Security dialog box containing a
check box to turn on security and one to four text boxes for entering the key.
Simply select the check box to enable WEP, enter your key in the appropriate
text box, and then click OK. Figure 9-2 shows this process using Windows XP
and its built-in Wireless Zero Configuration client.

Chapter 9: Securing Your Wireless Home Network
The last step we recommend that you take in the process of securing your
wireless home network (if your access point allows it) is to create a closed
network — a network that allows only specific, predesignated computers and
devices onto it. You can do two things to close down your network, which
makes it harder for strangers to find your network and gain access to it:
� Turn off SSID broadcast: By default, most access points broadcast their
SSID out onto the airwaves. This makes it easier for users to find the network
and associate with it. If the SSID is being broadcast and you’re in
