Introduction
The D-Link AirPlusXtremeGDWL-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-LinkAirXtremeGproducts. 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
Peer-to-Peer
mode (without an
Access Point) or 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

D-Link wireless products are based on industry standards to provide easy-to-
useandcompatiblehigh-speedwirelessconnectivitywithinyourhome,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
suchasairports,coffeeshopsanduniversities.InnovativewaystoutilizeWLAN
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.

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-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.

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.
Thismeansthatinmostenvironments,withinthespecifiedrangeofthisdevice,
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

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 isinteroperable with
existing compatible 2.4GHz wireless technology with data transfer speeds of
up to 11Mbps.

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.

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)
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
assignedanIPAddressof192.168.0.3withaSubnetMaskof255.255.255.0,
etc.
