Introduction
D-Linkannounces its latest addition tothe D-Link AirPlusXtremeTM Gseries of wireless
networking products–the DWL-G820 High-Speed Wireless GamingAdapter. The
DWL-G820adds802.11gwirelessconnectivitytoyourEthernet-enabledgamingconsole.
The DWL-G820 works with any Ethernet-ready game console, making it ideal for both
head-to-headand online gaming.Use Wireless GamingAdapterstowirelessly connect
two game systems to each other or use one to connect your system to a wireless
network.
Andwhennotgaming,youcanusetheDWL-G820tomakeanyEthernet-enableddevice,
suchas a media set-top box, wireless. The DWL-G820 is a true plug & playdevice that
requires no configuration and is ready to work right out of the box.
The Wireless GameAdapter is also highly configurable, using any Java-enabled Web
browser.Withsupportfor several advancedfeatures, includingWi-Fi ProtectedAccess
(WPA) and 128-bit WEP encryption, the Wireless Gaming Adapter also protects your
wirelesssignal.
The DWL-G820 uses D-Link 108 Technology for data transfer rates that are 15x faster
than standard 802.11b rates and works with all 802.11g networks. The device is also
backwards compatible with 802.11b wireless networks.This GamingAdapter provides
lag-freeperformance and allows your gaming console tojoin yourwireless network.

Wireless Basics
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
Ethernetadaptercards.
D-Link wireless products are based on industry standards to provide easy-to-use and
compatiblehigh-speedwirelessconnectivity withinyourhome,businessorpublicaccess
wirelessnetworks. D-Link wireless products will allow you access to the data you want,
whenandwhereyouwantit.Youwillbeabletoenjoythefreedomthatwirelessnetworking
brings.
AWirelessLocalAreaNetwork(WLAN)isacomputernetworkthattransmitsandreceives
datawithradio signals insteadof wires. WLANs areused increasingly in bothhome and
office environments, and public areas such as airports, coffee shops and universities.
Innovativewaysto utilizeWLANtechnologyarehelping peopletoworkandcommunicate
more efficiently. Increased mobility and the absence of cabling and other fixed
infrastructurehaveproven to bebeneficial for manyusers.
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
informationcan 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
technologyallows the network to go where wirescannot go- even outside the home or
office.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices. The DWL-G820 saves money by providing
multi-functionality, configurable in one of four different modes.
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
fromPeer-to-Peernetworkssuitable for a smallnumberof users to largerInfrastructure
networksto accommodate hundreds or thousands of users, depending on the number
ofwirelessdevices deployed.

The DWL-G820 is also interoperable with other 802.11g and 802.11b
standards-compliant devices.
Wireless Basics (continued)
Standards-Based Technology
TheDWL-G820WirelessGamingAdapterutilizesthe 802.11b andthe802.11gstandards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54Mbps (108Mbps in Super G mode) within the 2.4GHz band, utilizing
OFDM technology.
Thismeans that inmost environments, withinthe specified rangeof 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
digitaldataoveraradiowaveutilizingOFDM (OrthogonalFrequencyDivision Multiplexing)
technology. OFDM works by splitting the radio signal into multiple smaller sub-signals
that are then transmittedsimultaneously at different frequencies to the receiver. OFDM
reducestheamountofcrosstalk (interference)insignaltransmissions.TheD-LinkDWL-G820
will automatically sense the best possible connection speed to ensure the greatest
speedand range possible.
802.11g offers WPA, the most advanced networksecurity features available today.
The DWL-G820 is compatible, in default mode, with the following wireless products:

Installation Considerations
The D-Link AirPlus Xtreme G DWL-G820 lets you access your network, using a
wireless connection, from virtually anywhere within its operating range. Keep in mind,
however, that the number, thickness andlocation of walls, ceilings, orother objects that
thewirelesssignalsmustpassthrough,maylimittherange.Typicalrangesvarydepending
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:
TM
Keepyour product away (at least3-6 feet or 1-2 meters) from electricaldevices
orappliances that generate RF noise.

KeepthenumberofwallsandceilingsbetweentheDWL-G820andothernetwork
devices toaminimum- each wall or ceilingcanreduceyour DWL-G820’s range
from 3-90 feet (1-30 meters.) Position your devices so that the number of walls
or ceilings is minimized.

Beaware of the direct linebetween network devices.Awallthatis 1.5 feet thick
(.5meters), at a45-degree angle appearsto be almost 3 feet (1 meter) thick.At
a2-degreeangle it looks over42feet (14 meters) thick!Positiondevices so that
thesignal will travel straight through a wall or ceiling (instead of at anangle) for

Getting Started
With its default settings, the DWL-G820, when activated, will connect
with other D-Link AirPlus Xtreme G products, right out of the box.
Thereare basically two modes of networking:
Infrastructure – using an access point or router
Ad-Hoc –communicating withanother console,for Head to Head or
Peer-to-Peercommunication, using wireless network adapters, such
as two or more DWL-G820 Wireless Gaming Adapters, on
eachgaming console.

Thisexample illustrates an Ad-Hoc setup. Simply connect the DWL-G820 (refer to the
QuickInstallationGuide)to your Ethernet-capablenetworkdevice (inthiscase,agaming
console) and you will be able to connect wirelessly with other gaming consoles also
connectedto DWL-G820s.

Requirements for using the DWL-G820’s Web
Configuration Utility
Using the Configuration Menu
The DWL-G820 must be connected directly to your computer
for configuration. You cannot configure this device if it is
connected to a hub or router.
If you are incorporating the DWL-G820 into a network that contains all D-Link
devices, you do not need to use the Web Configuration utility. With its default
settings, the DWL-G820 will connect with other D-Link 802.11b or 802.11g devices
that are set to their default settings, with no configuration needed!
If your network contains devices other than D-Link devices, or if you wish to configure
the DWL-G820, you will need to do the following before using the Web Configuration
Utility:
You will need a Java-enabled Web browser such as the Internet Explorer
6.0 or later, or the Netscape Navigator 6.0 or later.
You will need to assign a static IP address to the computer that you are
using to configure the DWL-G820, within the IP address range of the
DWL-G820. TheDWL-G820has a defaultIP address of192.168.0.35 with
asubnet mask of 255.255.255.0
You can, for example, assignastaticIPaddressof192.168.0.2withasubnet
mask of 255.255.255.0 to the computer you will use for configuration.
(Please refer to theAppendix section of the Quick Installation Guide.)
