Installation Instructions
This chapter provides simple instructions for installing the
Wireless-G PC Card software on a Windows PC. If you have
already installed the adapter on a computer (using the separate
Quick Start booklet), you can skip this chapter and begin with
Chapter 2: Setting Security.
What’s in the Package
The Wireless-G PC Card adapter package includes the
following:
•Wireless-G PC Card
adapter
•Quick Start manual
•CD containing the
Installation Wizard and
documentation
Before You Begin
Before you install the Wireless-G PC Card adapter, check that
your computer has the following:
•PCMCIA slot
•Windows XP, 2000, Me,
or 98SE
•CD drive

Getting Connected
The installation places a Zoom Wireless-G PC Card icon on
your desktop:

1Double-click this icon to open the Wireless-G PC Card
configuration software:
In the Profile text box, the term “ANY” indicates that the
adapter has identified the strongest wireless network signal
in your vicinity – in your office building, for example, or in a
public space such as a cafe or airport.

2Select the Site Survey tab to see a list of wireless networks
within range:
There are two types of wireless networks: Infrastructure and
Ad Hoc.
•In an
Infrastructure network, wireless devices
communicate with each other via a wireless access
point, a router, or an ADSL modem with built-in wireless
technology.
•In an
Ad Hoc network, a group of wireless devices
communicate directly with other “client” devices that are
using wireless adapters. The network does not include a
wireless access point.
Important: When you join an Ad Hoc network, you need to
set up Static IP addressing. See Appendix A: TCP/IP
Settings on page 34.

Chapter 1: Installation Instructions 11
If the network you select has security configured, you
must enable and configure security on your computer before
you can connect. See Chapter 2, Setting Security on page
13.

4Your laptop should now be connected to the network, as
long as your security settings match those of the access
point and other network users. To check your connection,
open your Web browser and go to your favorite site.
If you have difficulty accessing the Internet, follow the
suggestions in your browser’s “Page cannot be displayed”
message. You may need to adjust your LAN settings.
As you work online, you can monitor your connection easily
using the Link Status icon that appears in the right corner of the
taskbar when you open the Wireless-G PC Card utility:
The icon’s color indicates the link status:
Blue indicates an excellent or good link.
Yellow indicates a usable but weak link.
Red indicates no link or a very poor link.

Setting Security
We strongly recommend security, although you do not need to
use it to get your wireless connection working.
Important! You must first enable security on the the wireless
access point. You then enable security on the adapter using the
same configuration that you used for the access point. For
example, if the wireless access point is configured for WPA2-
PSK, you must select WPA2-PSK security in the Wireless-G PC
Card configuration software and enter the same encryption key.
Select one of five ways to configure and implement security for
your wireless network:
•WPA2-PSK (WiFi ® Protected Access 2Pre-Shared Key) is
the recommended option if it is supported by the access
point and the devices in your network. WPA2-PSK protects
your communications with AES (Advanced Encryption
Standard). Some access points permit a “mixed mode”
network composed of both WPA and WPA2 wireless clients.
WPA2-PSK requires you to enter an encryption key shared
by the access point.
•WPA PSK (WiFi ® Protected Access Pre-Shared Key)
If the devices in your network do not all support WPA2-PSK,
select WPA-PSK. WPA-PSK protects your communications
with TKIP (Temporal Key Integrity Protocol).

Wireless-G PC Card Adapter14
This option requires you to enter an encryption key shared
by the access point.
•WEP (Wired Equivalent Privacy)
If the devices in your network do not support WPA2-PSK or
WPA-PSK, select WEP data encryption.
This method requires you to enter an encryption key. The
keys can be 64 or 128 bits in length.
•WPA2-Enterprise
If you are linking to a network that accesses a RADIUS
(Remote Authentication Dial-In User Service) authentication
server, and if the devices in the network support WPA2,
select WPA2-Enterprise. This option provides security with
AES (Advanced Encryption Standard). AES has a key size
of 128, 192, or 256-bits. In order for eavesdroppers to
decipher a message, they would have to try every possible
key.
•WPA is an option for users who access a RADIUS (Remote
Authentication Dial-In User Service) authentication server
that does not support WPA2. WPA provides security with
TKIP (Temporal Key Integrity Protocol), which dynamically
changes keys as the system is used.

aIn the Format for entering key drop-down list, select
•ASCII characters if your network uses all Zoom
wireless products
•Hexadecimal digits if an access point, router, or
some adapters are not Zoom products
bIn the Key Length drop-down list, select 128 bits or 64
bits.
Note: 128-bit WEP provides more security than 64-bit,
but 128-bit could diminish network performance.
cIn the Key Index drop-down list, if you are using a 64-bit
key, select which of four keys – 1, 2, 3, or 4 – will be
used to encrypt the data. The key you select must be the
same one that is selected on the access point. We
recommend that you use Key 1.
128-bit WEP uses just a single key.
