Introduction
The D-Link AirPlus Xtreme G DWL-G132 Wireless G USB Adapter is an
802.1 1b/802.1 1g high-performance,convenient Plug & Play USB 2.0 solution that
brings wireless networking to your laptop or desktop PC.
With a maximum wireless signal rate of up to 54Mbps (108Mbps* in Turbo
mode) you can connect to a wireless network at home, at the office or at any
wireless hotspot. Now you can stay connected wherever you are and wherever
you go.
The DWL-G132 is Wi-Fi compliant, meaning that it can connect and interoperate
with other 802.1 1b or 802.11g Wi-Fi-compliant wireless routers, access points
and adapters. The DWL-G132 connects to any available USB port on a laptop
or desktop Windows -based computer and also includes a USB cradle. With
the optional USB cradle, the DWL-G132 can be positioned virtually anywhere
at a workstation to achieve the best available wireless signal reception - whether
that workstation is in your office, on your deck or patio, by the pool, at the local
coffee shop, or in an airport terminal while waiting to board your next flight.
The adapter works with Microsoft Windows XP and Windows 2000 operating
systems to ensure that you’ll be up and running on a wireless network in just a
matter of seconds.
Using its default settings, the DWL-G132 automatically connects to other
D-Link AirPlus Xtreme G
TM
TM
wireless products as soon as it’s active.
The DWL-G132 has the newest, strongest and most advanced security features
available today. When used with other 802.11 WPA (Wi-Fi Protected Access)
and 802.1x compatible products in a network with a RADIUS server, the security
features include:
WPA: Wi-Fi Protected Access which authorizes and identifies users based
on a secret key that changes automatically at regular intervals. WPA
uses TKIP (T emporal Key Integrity Protocol) to change the temporal
key every 10,000 packets (a packet is a kind of message transmitted
over a network.) This ensures much greater security than the standard
WEP security. (By contrast, the previous WEP encryption
implementations required the keys to be changed manually.)
*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data
throughput will vary. Network conditions and evironmental factors lower actual data throughput rate.

Introduction (continued)
802.1x: Authentication which is a first line of defense against intrusion. In the
authentication process, the Authentication Server verifies the identity of
the client attempting to connect to the network. Unfamiliar clients would
be denied access.
For home users that will not incorporate a RADIUS server in their network, the
security for the DWL-G132, used in conjunction with other WPA-compatible
802.11 products, will still be much stronger than ever before. Utilizing the
Pre-Shared Key mode of WPA, the DWL-G132 will obt ain a new security key
every time it connects to the 802.11 network. You only need to input your
encryption information once in the configuration menu. No longer will you have
to manually input a new WEP key frequently to ensure security. With the
DWL-G132, you will automatically receive a new key every time you connect,
vastly increasing the safety of your communication.

Wireless Basics
D-Link wireless products are based on industry standards to provide
easy-to-use and compatible high-speed wireless connectivity within your home,
business or public access wireless networks. D-Link wireless products will
allow you access to the data you want, when and where you want it. Y ou will be
able to enjoy the freedom that wireless networking brings.
A wireless local area network (WLAN) is a computer network that transmits
and receives data with radio signals instead of wires. WLANs are used
increasingly in both home and office environments, and public areas such as
airports, coffee shops and universities. Innovative ways to utilize WLAN
technology are helping people to work and communicate more efficiently.
Increased mobility and the absence of cabling and other fixed infrastructure
have proven to be beneficial to many users.
Wireless users can use the same applications they use on a wired network.
Wireless adapter cards used on laptop and desktop systems support the same
protocols as Ethernet adapter cards.
People use WLAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any
location within the operating range of the WLAN. Management decisions based
on real-time information can significantly improve worker efficiency.
Low Implementation Costs - WLANs are easy to set up, manage, change
and relocate. Networks that frequently change can benefit from WLANs ease
of implementation. WLANs can operate in locations where installation of wiring
may be impractical.
Installation and Network Expansion - Installing a WLAN system can be fast
and easy and can eliminate the need to pull cable through walls and ceilings.
Wireless technology allows the network to go where wires cannot go - even
outside the home or office.
Inexpensive Solution - Wireless network devices are as competitively priced
as conventional Ethernet network devices.
Scalability - WLANs can be configured in a variety of ways to meet the needs
of specific applications and installations. Configurations are easily changed
and range from Peer-to-Peer networks suitable for a small number of users to
larger Infrastructure networks to accommodate hundreds or thousands of
users, depending on the number of wireless devices deployed.

Wireless Basics (continued)
Installation Considerations
The DWL-G132 lets you access your network using a wireless connection
from virtually anywhere within its operating range. Keep in mind, however, that
the number, thickness and location of walls, ceilings, or other objects that the
wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise
in your home or business. The key to maximizing wireless range is to follow
these basic guidelines:
Keep the number of walls and ceilings between the DWL-G132 and
1
other network devices to a minimum - each wall or ceiling can reduce
your DWL-G132’s range from 3-90 feet (1-30 meters.) Position your
devices so that the number of walls or ceilings is minimized.
Be aware of the direct line between network devices. A wall that is 1.5
2
feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet
(1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters)
thick! Position devices so that the signal will travel straight through a
wall or ceiling (instead of at an angle) for better reception.
3
Building materials can impede the wireless signal - a solid metal door
or aluminum studs may have a negative effect on range. T ry to position
wireless devices and computers with wireless adapters so that the
signal passes through drywall or open doorways and not other materials.
4
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.

Getting Started
With its default settings, the DWL-G132 will connect with other
D-Link AirPlus Xtreme G
There are basically two modes of networking:
Infrastructure – using an access point or router, such as the DI-624.
Ad-Hoc – directly connecting to another computer, for Peer-to-Peer
communication, using wireless network adapters on each computer,
such as two or more DWL-G132 Wireless Network USB adapters.
On the following pages we will show you an example of an Infrastructure
Network and an Ad-Hoc Network.
An Infrastructure network contains an access point or router. The
Infrastructure network example shown on the following page contains the
following D-Link network devices (your existing network may be comprised of
other devices):
