How to set up
a Home Wireless Lan
There are a few different setup
scenarios for wireless home networks, depending on whether
you already have a modem and a wired router. In this
step-by-step tutorial we'll assume that you already have a
broadband connection with a cable or DSL modem but don't yet
have a router, and that your computer is currently plugged
directly into your modem. We will also assume you want to
keep a desktop PC wired to the network and to set up either
a notebook or a second desktop PC for wireless access. (It's
a good idea to keep one of your PCs wired during
configuration, in case security settings are lost in the
process and you can't get back on the network.) You'll need
to buy a wireless router, a wireless PCI card for your
desktop PC, and a wireless PCMCIA card (also known as a PC
Card) for your notebook.
1. Connect Your Wireless
Turn off your cable modem and your wired PC.
Unplug the Ethernet cable from your cable modem and plug it
into one of the four LAN ports on the back of the wireless
router. The other end of the cable should remain connected
to your PC.
Connect a second Ethernet cable between your modem's
Ethernet port and the wireless router's WAN port. (The WAN
port is separate from the four grouped LAN ports.)
Turn on the modem and wait for the status lights to indicate
that it's connected to your service provider. This may take
up to a minute.
Plug in the router. The status lights will blink as it goes
through its own diagnostics; this may also take up to a
Boot up your wired PC.
2. Configure Your Router
Refer to the router's printed quick-start guide, launch
your Web browser, and type in the address indicated in
Follow the on-screen setup wizard, which should guide
you step by step through the process.
Enable your router's security functions. The options
will be WEP and WPA. (See page 88 for more information
on enabling WPA.) Both will ask you to enter a key.
Depending on your router's manufacturer, you may need to
go to Advanced Settings to handle this step and the next
Change the default administrator's password, which is
often known to hackers.
Change the SSID�Xthe name you give your wireless network.
Again, hackers know many of the default SSIDs and can
use them to join your network.
Install a Wireless PCI Card in a Desktop PC
Refer to the card manufacturer's quick-start guide. If
necessary, run the software installation program.
Shut down the PC.
Remove the cover.
Locate an available PCI slot and remove the corresponding
slot cover from the back of the PC.
Carefully route the antenna through the open slot in the
back of the PC, insert the card in the slot, and secure it.
Replace the cover.
Power up the PC. It should recognize and enable the new
Go to the Control Panel, select Network, select Wireless
Networking connection. Click on Properties. Click on
Wireless Networking tab. Select the wireless networking name
(see step 2e above). Click on Configure. Adjust your
security settings to match those on your wireless router.
4. Install a Wireless PC
Card in a Notebook PC
Many notebooks have built-in
wireless cards. If yours doesn't, follow these instructions.
Follow steps "a" and "b" in number 3.
Plug your wireless PC Card into an available slot on the
side of your notebook.
