You can use a wireless network to share Internet access, files, printers,
and more. Or you can use it to surf the Web while you're sitting on your
couch or in your yard. Plus, it's easier to install than you think.
For Windows XP users, Windows XP Service Pack 2 is not required for wireless networking, but
it does make things much easier. Service Pack 2 also helps protect you
against hackers, worms, and other Internet intruders.
1.
Choose your wireless equipment
The first step is to make sure that you have the equipment you need. As
you're looking for products in stores or on the Internet, you might
notice that you can choose equipment that supports three different
wireless networking technologies: 802.11a, 802.11b, and 802.11g. We
recommend 802.11g, because it offers excellent performance and is
compatible with almost everything.

A wireless router
The router converts the signals coming
across your Internet connection into a wireless broadcast, sort of like
a cordless phone base station. Be sure to get a wireless router, and not
a wireless access point.
A wireless network adapter
Network adapters wirelessly connect your computer to your wireless
router. If you have a newer computer you may already have wireless
capabilities built in. If this is the case, then you will not need a
wireless network adapter. If you need to purchase an adapter for a
desktop computer, buy a USB wireless network adapter. If you have a
laptop, buy a PC card-based network adapter. Make sure that you have one
adapter for every computer on your network.
Note: To make
setup easy, choose a network adapter made by the same vendor that made
your wireless router. For example, if you find a good price on a Linksys
router, choose a Linksys network adapter to go with it. To make shopping
even easier, buy a bundle, such as those available from D-Link, Netgear,
Linksys, Microsoft, and Buffalo. If you have a desktop computer, make
sure that you have an available USB port to plug the wireless network
adapter into. If you don't have any open USB ports, buy a hub to add
additional ports.
2.
Connect your wireless router
Since you'll be temporarily disconnected from the Internet, print
these instructions before you go any further.
First, locate
your cable modem or DSL modem and unplug it to turn it off.
Next, connect your wireless router to your modem. Your modem should
stay connected directly to the Internet. Later, after you've hooked
everything up, your computer will wirelessly connect to your router,
and the router will send communications through your modem to the
Internet.
Next, connect your router to your modem:
Note: The
instructions below apply to a Linksys wireless router. The ports on
your router may be labeled differently, and the images may look
different on your router. Check the documentation that came with
your equipment for additional assistance.
•
If you currently have your
computer connected directly to your modem: Unplug the
network cable from the back of your computer, and plug it into
the port labeled Internet, WAN, or WLAN on the back of your
router.
•
If you do not currently have a computer connected to the
Internet: Plug one end of a network cable (included with
your router) into your modem, and plug the other end of the
network cable into the Internet, WAN, or WLAN port on your
wireless router.
•
If you currently have your
computer connected to a router: Unplug the network cable
connected to the Internet, WAN, or WLAN port from your
current router, and plug this end of the cable into the
Internet, WAN, or WLAN port on your wireless router. Then,
unplug any other network cables, and plug them into the
available ports on your wireless router. You no longer need
your original router, because your new wireless router
replaces it.
Next, plug in and turn on your cable or DSL modem. Wait a few
minutes to give it time to connect to the Internet, and then plug in
and turn on your wireless router. After a minute, the Internet, WAN,
or WLAN light on your wireless router should light up, indicating
that it has successfully connected to your modem.
3.
Configure your wireless router
Using the network cable that came with your wireless router, you
should temporarily connect your computer to one of the open network
ports on your wireless router (any port that isn't labeled Internet,
WAN, or WLAN). If you need to, turn your computer on. It should
automatically connect to your router.
Next, open Internet
Explorer and type in the address to configure your router.
You
might be prompted for a password. The address and password you use
will vary depending on what type of router you have, so refer to the
instructions included with your router.
As a quick reference,
this table shows the default addresses, usernames, and passwords for
some common router manufacturers.

Internet Explorer will show your router's configuration page. Most
of the default settings should be fine, but you should configure
three things:
1.
Your wireless network name, known as the
SSID. This name identifies your network. You should choose
something unique that none of your neighbors will be using.
2.
Wireless encryption (WEP) or Wi-Fi
Protected Access (WPA), which help protect your wireless
network. For most routers, you will provide a passphrase
that your router uses to generate several keys. Make sure
your passphrase is unique and long (you don't need to
memorize it).
3.
Your administrative password, which
controls your wireless network. Just like any other
password, it should not be a word that you can find in the
dictionary, and it should be a combination of letters,
numbers, and symbols. Be sure you can remember this
password, because you'll need it if you ever have to change
your router's settings.
The exact
steps you follow to configure these settings will vary depending on
the type of router you have. After each configuration setting, be
sure to click Save Settings, Apply, or OK to
save your changes.
Now, you should disconnect the network
cable from your computer.
4.
Connect your computers
If your computer does not have wireless network support built in,
plug your network adapter into your USB port, and place the antenna
on top of your computer (in the case of a desktop computer), or
insert the network adapter into an empty PC card slot (in the case
of a laptop). Windows XP will automatically detect the new adapter,
and may prompt you to insert the CD that came with your adapter. The
on-screen instructions will guide you through the configuration
process.
Note: The steps below only apply if you're
using Windows XP Service Pack 2. If you're running Windows XP and
you don't have Service Pack 2 yet, plug your computer into your
wireless router and download
and install Windows XP Service Pack 2.
Windows XP should
show an icon with a notification that says it has found a wireless
network.
Follow these steps to connect your computer to your wireless
network:
1.
Right-click the wireless network icon in the
lower-right corner of your screen, and then click View
Available Wireless Networks. If you run into any problems,
consult the documentation that came with your network adapter.
Don't be afraid to call their tech support.
2.
The Wireless Network Connection window
should appear and you should see your wireless network
listed with the network name you chose. If you don't see
your network, click Refresh network list in the
upper-left corner. Click your network, and then click Connect in the lower-right corner.
3.
Windows XP prompts you to enter a key.
Type the encryption key that you wrote down earlier in both
the Network key and Confirm network key boxes, and
then click Connect.
4.
Windows XP will show its progress as it
connects to your network. After you're connected, you can
now close the Wireless Network Connection window. You're
done.
Note: If the Wireless
Network Connection window continues to show Acquiring Network
Address, you may have mistyped the encryption key.
