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. You will be able to enjoy the 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

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.

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.

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.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventional Ethernet network devices.

The DWL-520 is compatible with 802.11b wireless products, which include:

D-Link Air DWL-650,D-Link AirPlus DWL-650+

2.4GHz Wireless Cardbus Adapter used with laptop computers

D-Link AirPlus DWL-520+

2.4GHz Wireless PCI cards used with desktop computers

D-Link AirPlus DWL-900AP+

Enhanced 2.4GHz Wireless Access Point

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

Enhanced 2.4GHz Wireless Broadband Routers

Standards-Based Technology

Based on the IEEE 802.11b standard, the DWL-520 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-520 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:

Wireless Basics (continued)

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

devices or appliances that generate RF noise.

Keep the number of walls and ceilings between the DWL-520 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.

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! Position devices so

that the signal will travel straight through a wall or ceiling (instead of at an

angle) for better reception.

Building Materials can impede the wireless signal - 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.

There are basically two modes of networking:

Infrastructure – using an Access Point or Router, such as

the DI-614+

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-520 wireless

network 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):

Getting Started

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

A laptop computer with a wireless adapter -

D-Link Air DWL-650

A desktop computer with a wireless adapter -

D-Link Air DWL-520

A Cable modem - D-Link DCM-200

With its default settings, the DWL-520, 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

Connect the Cable or DSL modem to your broadband router (see the Quick

Installation Guide included with your router.)

Install the D-Link Air DWL-520 wireless PCI adapter into an available PCI slot

on your desktop computer.

(See the Quick Installation Guide included with the DWL-520.)

(See the Quick Installation Guide included with the DWL-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

network adapter (such as a DFE-530TX+) to the router also.

Getting Started (continued)

Setting up a Wireless Ad Hoc Network

Install the DWL-520 into the desktop computer.

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

instructions.)

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

Desktop

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.

In Ad-Hoc mode, both wireless clients will need to have the same SSID.

Please note that it might be necessary to set up one client to establish a

BSS (Basic Service Set) and wait briefly before setting up other clients.

This prevents several clients from trying to establish a BSS at the same

time, which can result in multiple singular BSSs being established, rather

than a single BSS with multiple clients associated to it.

below will be free from material defects in workmanship and materials from the date of original retail

purchase of the product, for the period set forth below applicable to the product type (“Warranty

Period”), except as otherwise stated herein.

1-Year Limited Warranty for the Product(s) is defined as follows:

•Hardware (excluding power supplies and fans) One (1) Year

•Power Supplies and Fans One (1) Year

•Spare parts and spare kits Ninety (90) days

D-Link’s sole obligation shall be to repair or replace the defective Hardware during the Warranty Period

at no charge to the original owner or to refund at D-Link’s sole discretion. Such repair or replacement will

be rendered by D-Link at an Authorized D-Link Service Office. The replacement Hardware need not be

new or have an identical make, model or part. D-Link may in its sole discretion replace the defective

Hardware (or any part thereof) with any reconditioned product that D-Link reasonably determines is

substantially equivalent (or superior) in all material respects to the defective Hardware. Repaired or

replacement Hardware will be warranted for the remainder of the original Warranty Period from the date

of original retail purchase. If a material defect is incapable of correction, or if D-Link determines in its sole

discretion that it is not practical to repair or replace the defective Hardware, the price paid by the original

purchaser for the defective Hardware will be refunded by D-Link upon return to D-Link of the defective

Hardware. All Hardware (or part thereof) that is replaced by D-Link, or for which the purchase price is

refunded, shall become the property of D-Link upon replacement or refund.

ninety (90) days (“Warranty Period”), provided that the Software is properly installed on approved

Warranty Period, the magnetic media on which D-Link delivers the Software will be free of physical

defects. D-Link’s sole obligation shall be to replace the non-conforming Software (or defective media)

with software that substantially conforms to D-Link’s functional specifications for the Software or to

refund at D-Link’s sole discretion. Except as otherwise agreed by D-Link in writing, the replacement

Software is provided only to the original licensee, and is subject to the terms and conditions of the

license granted by D-Link for the Software. Software will be warranted for the remainder of the original

Warranty Period from the date or original retail purchase. If a material non-conformance is incapable of

correction, or if D-Link determines in its sole discretion that it is not practical to replace the non-

conforming Software, the price paid by the original licensee for the non-conforming Software will be

refunded by D-Link; provided that the non-conforming Software (and all copies thereof) is first returned

to D-Link. The license granted respecting any Software for which a refund is given automatically

terminates.
