Introduction
TM
The D-Link AirPlusXtremeG DWL-G650 Wireless Cardbus Adapter is an enhanced
802.11g high-performance, wireless adapter that supports high-speed wireless networking
at home, at work or in public places.
Unlike most network cards, the DWL-G650 provides speeds of up to 54 Mbps (compared
to the standard 11 Mbps) when used with other D-Link AirXtremeG products. This means
that you do not need to change your entire network to maintain connectivity. You may
sacrifice some of 802.11g’s speed when you mix 802.11b and 802.11g devices, but you
will not lose the ability to communicate when you incorporate the 802.11g standard into
your 802.11b network. You may choose to slowly change your network by replacing the
802.11b devices with 802.11g devices gradually.
In addition to offering faster data transfer speeds when used with other 802.11g products,
the DWL-G650 has the newest, strongest, most advanced security features available
today.
For home users that will not incorporate a radius server in their network, the security for
the DWL-G650, used in conjunction with other 802.11g products, will be much stronger
than ever before. No longer will you have to manually input a new WEP key frequently to
ensure security, with the DWL-G650, you will automatically receive a new key every
time you connect, vastly increasing the safety of your communications.
The DWL-G650 is compatible with existing 802.11b devices such as the D-Link Air,
AirPlus and AirPro family of products including the DWL-520, DWL-520+ and the
DWL-AB520 Wireless PCI Adapter, the DI-714 Wireless Router/Access Point and the
DWL-120 Wireless USB Adapter. (When used with 802.11b devices, the DWL-G650
will reach speeds at up to 11Mbps.)
It is an ideal way to connect one laptop computer to a Wireless Local Area Network
(WLAN.) After completing the steps outlined in the Quick Installation Guide
(included in the package) you will have the ability to share information and resources,
such as files and printers, and take full advantage of a “connected” environment for
work or play!
The DWL-G650 includes software drivers for the most popular Microsoft Windows
operating systems (Windows XP, Windows 2000, Windows Me, Windows 98) and can
be integrated into a larger network, running, in either Access Point mode (without an
Access Point) or Peer-to-Peer mode (with an Access Point.) Please take a look at
our Getting Started section in this manual to see examples of typical network setups
using the DWL-G650 in both Access Point and Peer-to-Peer modes.
This manual provides a quick introduction to wireless technology and its application
as it relates to networking. Take a moment to read through this manual and get
acquainted with wireless technology.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-touse and compatible high-speed wireless connectivity within your home, business
or public access wireless networks. Strictly adhering to the IEEE standard, the
D-Link wireless family of products will allow you to securely access the data
you want, when and where you want it. You will be able to enjoy the freedom
that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that
transmits and receives data with radio signals instead of wires. Wireless LANs
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 for 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.
Under many circumstances, it may be desirable for mobile network devices to
link to a conventional Ethernet LAN in order to use servers, printers or an Internet
connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.
Wireless Basics (continued)
People use wireless LAN 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 (Wireless Local Area Networks) are
easy to set up, manage, change and relocate. Networks that frequently change,
both physically and logically, can benefit from WLANs ease of implementation.
WLANs can operate in locations where installation of wiring may be impractical.
Installation Speed and Simplicity - Installing a wireless LAN system can
be fast and easy and can eliminate the need to pull cable through walls and
ceilings.
Network Expansion - Wireless technology allows the network to go
where wires cannot.
Scalability – Wireless Local Area Networks (WLANs) can be configured in a
variety of topologies to meet the needs of specific applications or existing
infrastructures. Configurations are easily changed and range from peer-topeer 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.
The DWL-G650 is also compatible with 802.11b wireless products, which include:
n 2.4GHz Wireless Cardbus Adapters used with laptop computers
(D-Link Air DWL-650, D-Link AirPlus DWL-650+)
n 2.4GHz Wireless PCI cards used with desktop computers
(D-Link Air DWL-520, D-Link AirPlus DWL-520+)
n Enhanced 2.4GHz Wireless Access Point
(D-Link AirPlus DWL-900AP+)
n Enhanced 2.4GHz Wireless Broadband Router
(D-Link AirPlus DI-614+)
Wireless Basics (continued)
Standards-Based Technology
The DWL-G650 Wireless Cardbus Adapter increases the data rate up to 54
Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specified range of this device,
you will be able to transfer large files quickly or even watch a movie in MPEG
format over your network without noticeable delays. This technology works by
transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal
Frequency Division Multiplexing) technology. OFDM works by splitting the radio
signal into multiple smaller sub-signals that are then transmitted simultaneously
at different frequencies to the receiver. OFDM reduces the amount of crosstalk
(interference) in signal transmissions. The D-Link DWL-G650 will automatically
sense the best possible connection speed to ensure the greatest speed and
range possible.
The DWL-G650 is backwards compatible with 802.11b devices. This means
that if you have an existing 802.11b network, the devices in that network will be
compatible with 802.11g devices at speeds up to 11Mbps in the 2.4GHz range.
Also based on the IEEE 802.11b standard, the DWL-G650 is interoperable with
existing compatible 2.4GHz wireless technology with data transfer speeds of
up to 11Mbps.
Wireless Basics (continued)
Installation Considerations
The D-Link AirExtreme DWL-G650 lets you access your network, using a
wireless connection, from virtually anywhere. 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:
1. Keep the number of walls and ceilings between the DWL-G650 and
other network devices to a minimum - each wall or ceiling can reduce
your D-Link AirExtreme Wireless product’s range from 3-90 feet (1-30
meters.) Position your devices so that the number of walls or ceilings is
minimized.
2. Be aware of the direct line between network devices. A wall that is
1.5 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! Try to make sure that devices are positioned so that the signal will
travel straight through a wall or ceiling for better reception.
3. Building Materials make a difference - a solid metal door or aluminum
studs may have a negative effect on range. Try 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
There are basically two modes of networking:
Access Point – using an Access Point, such as the
DWL-900AP.
Peer-to-Peer – directly connecting to another computer, for
peer-to-peer communication, using wireless network adapters
on each computer, such as two or more DWL-G650 wireless
network Cardbus 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. To utilize the
full features of the DWL-G650 you will need to include a radius server in your
network. 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):
A wireless Access Point - D-Link Air 900AP
A laptop computer with a wireless adapter D-Link AirPlus DWL-G650
A desktop computer with a wireless adapter D-Link Air DWL-520
(802.11b devices have speeds up to 11Mbps)
A Cable modem - D-Link DCM-200

Getting Started
Setting up a Wireless Infrastructure Network
Please remember that D-Link AirXtremeG wireless devices are pre-configured to
connect together, right out of the box, with their default settings.
For a typical wireless setup at home (as shown above), please do the
following:
You will need broadband Internet access (a Cable or DSL-subscriber line into
your home or office)
Consult with your Cable or DSL provider for proper installation of the modem
Connect the Cable or DSL modem to your broadband router (see the Quick
Installation Guide included with your router.)
If you are connecting a desktop computer to your network, install the D-Link Air
DWL-520 wireless PCI adapter into an available PCI slot on your desktop
computer. You may also install the DWL-520+.
(See the Quick Installation Guide included with the network adapter.)
Install the drivers for the D-Link DWL-G650 wireless Cardbus adapter into a
laptop computer.
(See the Quick Installation Guide included with the DWL-G650.)
12
Getting Started
Setting up a Wireless Ad Hoc Network
Install the D-Link DWL-G520 Wireless Network adapter into one
laptop computer. See the Quick Installation Guide included with the
product for installation instructions.
Install another DWL-G650 into a laptop computer. See the Quick
Installation Guide included with the product.
Set the wireless configuration for the adapters to Ad-Hoc mode, set
the adapters to the same channel, and assign an IP Address to
each computer on the Ad-Hoc network. (See Box below)
IP Address
When assigning IP Addresses to the computers on the network, please
remember that the IP Address for each computer must be in the same
IP Address range as all the computers in the network, and the subnet
mask must be exactly the same for all the computers in the network.
For example: If the first computer is assigned an IP Address of 192.168.0.2
with a Subnet Mask of 255.255.255.0, then the second computer can be
assigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255.0,
etc.
IMPORTANT: If computers or other devices are assigned the same IP
Address, one or more of the devices may not be visible on the network.
