that you used when you set up the AP.
Refer to the discussion of Pocket PC 2002 (later in this chapter) for more
information about configuring wireless client software on your Pocket PC.
6. On the Pocket PC, run the wireless network adapter™s configuration
program.
To run the configuration utility for the Linksys WCF11 wireless adapter,
for example (shown in Figure 7-2), you choose Start➪Programs and then
click the WCF11 Config icon. You might have to unplug the card and rein-
sert for the configuration utility to be able to “see” the card the first time.

7. Using the wireless adapter™s configuration utility on the Pocket PC,
turn on the encryption feature and enter the same encryption key
that you entered in the AP™s configuration software.
At this point, you should have a valid link between the wireless network
adapter in the Pocket PC and the AP. (The Linksys utility, for example,
has a Link button that you can click to display a screen showing link

quality and signal strength.) You aren™t quite ready to use the wireless
card to synchronize your Pocket PC with your PC, however. You must
follow the steps in the later section, “Getting Set for Synchronizing and
Internet Access,” to do just that.



PCI and ISA cards
If you purchased a wireless networking adapter that fits inside your PC, you
must make sure that you have the right type for your computer. Most desk-
top computers built in the last five years contain at least one PCI slot. Older
desktop computers might have only Industry Standard Architecture (ISA)
slots. Refer to your computer™s documentation to determine which type of
slot is inside your computer and then purchase a wireless network interface
adapter to match.

Some manufacturers choose to mount a PC Card on a PCI or an ISA adapter.
Some of the newest PCI adapters consist of a mini-PCI adapter mounted to a
full-sized PCI adapter. In either of these configurations, a black rubber dipole-
type antenna, or another type of range-extender antenna, is attached to the
back of the PCI or ISA adapter.

Most PCI or ISA cards come with specific software and instructions for
installing and configuring the card. We can™t tell you exactly what steps you™ll
need to take with the card that you buy, but we can give you some generic
steps. And don™t forget to read the manual and follow the onscreen instruc-
tions on the CD that comes with your particular card.

Follow these general guidelines for installing a PCI or ISA adapter card:

1. Insert the CD that accompanied the adapter into the CD-ROM drive.
If necessary, choose Start➪Run (in Windows) or open Windows Explorer
to run the Setup.exe program on the CD.
2. Select the option for installing the PCI or ISA card driver software.
At this point, the driver will only be copied to the computer™s hard drive.
The driver will be added to the operating system in Step 4.
3. If prompted to restart the computer, select No, I Will Restart My
Computer Later and then click the Next (or Finish) button.
During the install process, many Windows-based computers will prompt
you to restart the computer by displaying a pop-up box with a question
similar to “New drivers have been installed, do you want to restart for
the changes to take effect?” The normal reaction might be to do what it
asks and click the OK button ” but don™t! The software installation
needs to fully complete before the computer can be restarted. You will

know it™s completed because the installation wizard (not a Windows
pop-up) will prompt you for your next step. After the software has com-
pleted its installation process, it will prompt you in its own software
window to restart your computer, or it will inform you that you need to
restart to complete the installation.
4. After the computer restarts, install the PC Card wireless station
(client) software in accordance with the instructions that came with it.
In some cases, Steps 2 and 4 are accomplished in a single software-
installation step. In other cases, you will only install the wireless station
software at this point.
While the wireless station software is installing, you might need to indi-
cate whether you want the PC Card to be set to infrastructure (AP)
mode or to ad hoc (peer-to-peer) mode. Choose infrastructure mode to
cause the wireless network adapter to use the AP to communicate with
other network devices. You might also need to provide the SSID (net-
work name) and to indicate whether you will use WEP encryption.
5. After both the PCI card or ISA card driver and the wireless station
software are installed, shut down the computer.
6. Unplug the computer and install the PCI card or ISA card in an avail-
able slot.
7. Plug in the computer and restart it.
Although most internal Wi-Fi adapters use the PCI bus in your PC, a few
use the ISA bus. (This is an older system that™s gradually being phased
out of newer computers.) Most of the time, PCI systems will automati-
cally detect the new hardware that you™ve installed (the wireless net-
work adapter) when you restart the computer. If you™re using an ISA
adapter, you might have to manually prompt the computer to recognize
the new card by using the Add/Remove Hardware Wizard. To start the
wizard, choose Start➪Settings➪Control Panel and then double-click the
Add/Remove Hardware icon.
Windows will recognize that you have installed new hardware and will
automatically search the hard drive for the driver. When Windows finds
the driver, it will enable the driver for the adapter, and you™re done.



USB adapters
If you purchased a USB adapter, these are easy to install in your USB port. All
new PCs and laptops come with at least one (and usually two) USB port(s).
Most USB adapters attach to the USB port via a USB cable. Some new devices
are so lightweight and compact that you can plug them directly into the USB
port. (Refer to Chapter 8 if you are a Mac user.)
126 Part III: Installing a Wireless Network

The general guidelines for installing a USB wireless NIC are as follows:

1. Insert the CD that accompanied the USB adapter into the CD-ROM drive.
If the CD™s AutoRun feature doesn™t cause the setup program to start,
use the Run command from the Start button (in Windows) or open
Windows Explorer to run the Setup.exe program on the CD.
2. Install the wireless station (client) software.
During the installation of the wireless station software, you might be
asked to indicate whether you want the USB wireless adapter to be set
to infrastructure (access point) mode or to ad hoc (peer-to-peer) mode.
Choose infrastructure mode to cause the wireless network adapter to
use the AP to communicate with other network devices. You might also
be asked for the SSID (network name) and to indicate whether you will
use WEP encryption.
3. After the wireless station software is installed, restart the computer.
4. After the computer restarts, attach the USB adapter to one of the com-
puter™s USB ports by running a USB cable from the network adapter to
the USB port.
Windows should recognize that you have installed new hardware and
will automatically search the hard disk for the driver. When Windows
finds the driver, it will enable the driver for the adapter. That™s it ”
you™re all finished.




Modifying Wireless Network Adapters
Some occasions might warrant modifying one or more of the adapters™ para-
meters. For example, you might need to change the adapter™s WEP key or
SSID to match changes that you have made to the AP. The wireless network
adapter™s manufacturer has provided utility software for this purpose. For
example, Figure 7-3 shows the ORiNOCO (www.proxim.com) Client Manager
program that you can use to select a different wireless network SSID or to
change the WEP key. (For more about SSIDs and WEP keys, see the step lists
in the first section of this chapter.)

Chapter 7: Setting Up Your Windows PCs for Wireless Networking

If you use Windows XP, however, you can use the operating system™s utilities
to change settings in your wireless network interface adapter. Windows XP is
the first Windows OS that has support for wireless networking built in. We
talk about this built-in support in the later section “Windows XP™s Wireless
Zero Configuration.”




Synchronizing and Internet Access
To get your Pocket PC to synchronize with your PC through the wireless
adapter ” and to enable wireless access to the Internet ” follow these gen-
eral steps:

1. On the Pocket PC, choose Start➪Settings➪Connections➪Network
Adapters. Then select the wireless network adapter from the list of
installed adapters on the Network Adapters screen and click Properties.
A screen similar to what™s shown in Figure 7-4 appears. Click the
IP Address tab. Marking the default setting (the Use Server-Assigned IP
Address radio button) is easiest. The DHCP server on your network that
assigns the IP addresses for all the other devices on the network will
also assign the IP address for your Pocket PC.

2. Determine the IP address of the PC with which the Pocket PC will
synchronize.
• If your PC runs Windows 95/98/SE/Me, choose Start➪Run, type
winipcfg, and then click OK to display the IP Configuration window.
Select the PC™s network adapter from the drop-down list. Copy
down the IP address for the PC™s network adapter and then close
the IP Configuration window.
128 Part III: Installing a Wireless Network

• If your PC runs Windows 2000/XP, choose Start➪(All)
Programs➪Accessories➪Command Prompt. In the command
prompt window that appears, type ipconfig, and then press Enter.
Copy the IP address for the PC™s network adapter and then close
the command prompt window.
3. On the Pocket PC, go to the Name Servers tab of the wireless network
adapter™s Properties screen.
You accessed the Properties screen in Step 1; it should still be visible on
the Pocket PC.
4. In the WINS text box, enter the PC™s IP address that you copied in
Step 4.
Figure 7-5 shows the Name Servers tab with WINS address filled in.




Figure 7-5:

a WINS
address.



You should now be able to wirelessly synchronize the Pocket PC with the
PC. And if your wireless network is connected to the Internet, you should
be able to wirelessly access the Internet on your Pocket PC. To check for
the functionality of these two features, proceed to Steps 5 and 6.
5. While the Pocket PC is not in its cradle, choose Start➪ActiveSync and
then click the Sync button (on the ActiveSync screen that appears).
You should see the ActiveSync pop-up window on the PC and a message
on the Pocket PC telling you that the two computers are synchronizing.
6 Launch Internet Explorer and browse the Internet to find out whether
you have wireless access to the Internet.

Chapter 7: Setting Up Your Windows PCs for Wireless Networking


Wireless Zero Configuration with XP
Windows XP promises to make connecting to new wireless networks easier
through a service that Microsoft has dubbed Wireless Zero Configuration.
Although Microsoft™s claim of zero configuration is a bit of an exaggeration,
configuration is pretty easy. When installing or configuring a wireless adapter
that™s supported by Windows XP, you don™t need to use software provided by
the manufacturer. Instead, Windows XP itself recognizes the adapter and pro-
vides the necessary driver and configuration software.



Easy installation
As an alternative to the manufacturer™s installation and configuration soft-
ware, follow these steps to install and configure a supported wireless net-
work adapter. (Note: We recommend that you check the documentation that
accompanies your wireless adapter to determine whether it is supported by
Windows XP Zero Configuration before continuing with these steps.)
