Introduction

TheD-Link Air DWL-650 Wireless PCCard Adapter is an802.11b wireless adapter that

supports high-speed wireless networking at home, at work or in public places.

The DWL-650 is compatible with existing 802.11b devices such as the D-Link Air and

AirPlus family of products including the DWL-520 and DWL-520+ Wireless PCIAdapt-

ers, the DI-614+ Wireless Router, DWL-900AP+ WirelessAccess Point and the DWL-

122 Wireless USBAdapter.

TheDWL-650 is an ideal way to connect yourlaptop computer toa Wireless LocalArea

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,

suchas files and printers, and enjoy the freedom thatwireless networking delivers.

The DWL-650 comes with software drivers for the most popular Microsoft Windows

operating systems and can be integrated into a larger network, running Windows XP,

Windows 2000, Windows Me, or Windows 98SE in either Ad Hoc mode (without an

Access Point or Router) or Infrastructure mode (with anAccess Point or Router).

The IEEE 802.11b Ethernet standard allows you to connect computers and 802.11b

compatible devices at speeds up to 11Mbps, dependent upon the distance between

wirelessadapters, the configuration of your working environment, or the capabilities or

limitations of your computer systems.

Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to-use and

compatiblehigh-speedwirelessconnectivity withinyourhome,business or publicaccess

wirelessnetworks. D-Link wirelessproducts will allow you access to the data you want,

whenandwhereyouwantit.Youwillbeabletoenjoythe freedom that wireless networking

brings.

A Wireless Local Area Network (WLAN) is a cellular computer network that transmits

and receives data with radio signals instead of wires. WLANs are used increasingly in

bothhome and officeenvironments, andpublic areassuchas airports,coffee shopsand

universities.Innovative waysto utilize WLAN technology arehelping peopleto workand

communicatemore efficiently.Increased mobilityand the absence of cabling and other

fixedinfrastructure haveproven to be beneficial formany 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

Ethernetadapter cards.

Peopleuse 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.NetworksthatfrequentlychangecanbenefitfromWLANseaseofimplementation.

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.

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-peer networks suitable for a small number of users to largerinfrastructure

networkstoaccommodate hundredsorthousands ofusers, depending onthe number of

wirelessdevices deployed.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventionalEthernetnetwork devices.

The DWL-650 is compatible with 802.11b wireless products, which include:

D-Link AirPlus DWL-650+

2.4GHzWireless PC CardAdapterusedwith laptop computers

D-Link Air DWL-520, D-Link AirPlus DWL-520+

2.4GHz Wireless PCI cards used with desktop computers

D-Link AirPlus DWL-900AP+

Enhanced 2.4GHz WirelessAccess Point

D-Link AirPlus DI-614+, DI-714P+

Enhanced2.4GHz Wireless Broadband Routers

Standards-Based Technology

Based on the IEEE 802.11b standard, the DWL-650 is also interoperable with existing

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

Installation Considerations

The D-Link Air DWL-650 lets you access your network, using a wireless connection,

fromvirtuallyanywherewithinitsoperatingrange.Keepinmind,however,thatthenumber,

thickness and location of walls, ceilings, or other objects that the wireless signals must

passthrough,maylimittherange.Typicalrangesvarydependingonthetypesofmaterials

and background RF (radio frequency) noise in your home or business. The key to

maximizing wireless range is to follow these basic guidelines:

Wireless Basics (continued)

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

devicesor appliances that generate RF noise.

Keepthe number of wallsand ceilings between the DWL-650 and

other network devices to a minimum - each wall or ceiling can reduce

your D-Link Air Wireless product’s range from 3-90 feet (1-30 meters.)

Position your devices so that the number of walls or ceilings is minimized.

Beaware ofthe directline betweennetwork devices.Awall that is 1.5 feet thick

(.5meters), ata 45-degreeangle 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 betterreception.

studsmayhave anegative effect onrange. Tryto position wirelessdevices and

computerswith wireless adapters so that the signal passes throughdrywall or

opendoorways and notother materials.

Thereare basically two modes of networking:

Infrastructure – using anAccess Point or Router, such as

theDI-614+

Ad-Hoc –directly connecting toanother computer,forpeer-to-

peercommunication, using wirelessnetwork adapters on

each computer, such as two or more DWL-650 wireless

networkadapters.

On the following pages we will show you an example of an Infrastructure Network

andan Ad-Hoc Network.

AnInfrastructure network contains anAccess Point or Router. The Infrastructure

Network exampleshown on the following page contains thefollowing D-Link network

devices(your existing network may be comprised of other devices):

Getting Started

A wireless Router- D-Link AirPlus DI-614+

A laptop computer with a wireless adapter -

D-LinkAir DWL-650

A desktop computer with a wireless adapter -

D-LinkAir DWL-520

ACable modem- D-Link DCM-200

With its default settings, the DWL-650, when activated, will connect

with other D-Link Air products, right out of the box.

Please remember that D-Link Air wireless devices are pre-configured to connect

together, right out of the box, with their default settings.

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

Connectthe Cable or DSL modemto your broadband router (seethe Quick

Installation Guide includedwithyourrouter.)

Installthe D-Link AirDWL-520 wireless PCI adapter into an available PCI slot

onyour desktop computer.

(Seethe Quick Installation Guide includedwiththe DWL-520.)

Install theD-Link AirDWL-650 wireless PC Cardadapter intoa laptop computer.

(Seethe Quick Installation Guide includedwith theDWL-650.)

Getting Started (continued)

For a typical wireless setup at home (as shown above), please do the

following:

Setting up a Wireless Infrastructure Network

If you wish, you may connect a computer that is equipped with an Ethernet

networkadapter (suchas aDFE-530TX+) tothe routeralso.

Getting Started (continued)

Setting up a Wireless Ad Hoc Network

Install the Wireless PCI adapter(e.g., DWL-520) into the desktop computer.

(See the Quick Installation Guide included with the product for installation

instructions.)

Install the DWL-650 wireless PC Card adapter into a laptop computer. (See

the Quick Installation Guide includedwith the product.)

Set the wireless configuration for the adapters toAd-Hoc mode, set the

adapters to the same channel, and assign an IPAddress to each computer

on theAd-Hoc network. (See Box below)

IPAddress

Desktop

When assigning IPAddresses 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 IPAddress 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 IPAddress,

one or more of the devices may not be visible on the network.
