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 or

business. Strictly adhering to IEEE 802.11a/b/g the D-Link wireless family

of products will allow you to access the data you want, when and where you

want it. No longer will you be limited to one location or forced to run new

wiring through your home or office. You will be able to enjoy the freedom that

wireless networking delivers.

A wireless LAN (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. 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 has proven to be beneficial for many users.

Wireless users can use the same network applications they use on an

Ethernet LAN. Wireless adapter cards used on laptop and desktop systems,

support the same protocols as Ethernet adapter cards. For most users, there

is no noticeable functional difference between a wired Ethernet desktop

computer and a wireless computer equipped with a wireless adapter other

than the added benefit of the ability to roam within the wireless-cell. 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 Access

Point (AP) is a device used to provide this link.

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. Ad-hoc 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, both physically and logically,

can benefit from WLANs ease of implementation. WLANs can operate in

locations where installation of wiring may be impractical. Furthermore, IEEE

standardization mandates interoperability of all WLAN devices that conform

to the 802.11a/b/g set of standards.

Installation Flexibility - Wireless technology allows the network to go where

wires cannot go.

Installation Considerations

Designed to go up to 1650 feet (~500 meters), D-Link DWL-AG520 lets you

access your network with your computer from virtually anywhere you want.

Keep in mind, however, that the number and thickness of walls, ceilings or

other objects that the wireless signals must pass thru may limit range.

Typical ranges vary depending on the types of materials and background RF

noise in your home or business. The key to maximizing range is to follow

these basic principles:

1. Keep the number of walls and ceilings between the Access Point and

your receiving device to a minimum - Each wall or ceiling can reduce

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

some businesses or for a large residential home deployment, it may be

beneficial to have more than one access point with overlapping coverage.

2. Be aware of the direct line between Access Points and computers with

wireless adapters - 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 the

Access Points and Adapters 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 Access Points,

and computers with wireless adapters so that the signal passes through

drywall or open doorways and not other materials.

4. Make sure that the antenna is positioned for best reception by using the

software signal strength tools included with your product.

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

devices or appliances that generate extreme RF noise.

Getting Started

To begin, select the type of wireless network you will be building.

We will discuss the following types of networks in this section:

1. A Home Internet Network

with A Residential Gateway/Router

2. A Home Internet Network with Multiple IP Addresses

3. An Ad Hoc Network

4. An Ad Hoc Network with Internet Sharing

Please select, from the four types of networks described above, the type of

network that is appropriate for your needs. Please follow the instructions in

the corresponding section that follows.

1. A Home Internet Network with A Residential Gateway/Router

(Network administrators with Dynamic IPs can also follow these instructions.)

If you have two or more computers (laptops or desktops) and want to share

files, printers, and Internet access using a DHCP-capable Residential

Gateway/Router – or - if you want to connect to an Ethernet network that

uses Dynamic (DHCP) IP addresses, then follow the instructions on the next

page. When it is complete, your network may look similar to this:

1. A Home Internet Network with A Residential Gateway/Router

This type of installation requires that you provide a dynamic IP address for

each computer on your network. You will need a DHCP-capable Residential

Gateway/Router for your network.

DHCP stands for

Dynamic Host

Configuration Protocol.

It is a protocol for

assigning dynamic IP

addresses

“automatically.” With a

DHCP-capable

gateway, there is no

need to manually

assign an IP address.

To complete the installation, please follow these steps:

1. Connect the Router/Gateway (for example, the D-Link DI-704P) to

a Broadband connection, Connect the 802.11a/b/g Access Point to

the router.

2. Install the D-Link DWL-AG520 Wireless PCI Adapter into a

desktop computer on your wireless network. (You can also install the

Wireless Cardbus Adapter into a laptop computer. Please refer to

the Quick Install Guide included with each product.)

3. Check the Device Manager to confirm that the wireless adapter is

installed correctly. Please refer to the Networking Basics section in

this manual entitled: Checking the Installation of the Drivers for

the Wireless Adapter.

4. By default, the wireless adapter is set to obtain a Dynamic IP

Address. If you are having difficulty connecting, check to make sure

that the IP Address of the wireless adapter is within the IP address

range of your network. Please refer to the Networking Basics

section in this manual entitled: Checking The IP Address.

5. Learn to share printers and files. Please refer to the Networking

Basics section in this manual entitled: Adding and Sharing Printers

in Windows XP.

2. A Home Internet Network with Multiple IP Addresses

(Network administrators with Static IPs can also follow these instructions.)

If you have two or more computers (laptops or desktops) and want to share

files, printers, and Internet access using multiple IP addresses that you have

purchased from your Internet Service Provider -or- you want to connect to

an Ethernet network that uses Static IP Addresses, then follow the

instructions on the next page. When you have completed your network, it

should look similar to this:

Please note that this type of installation requires that your ISP (Internet

Service Provider) provides you a static IP address for each computer and

the Access Point on your network. Please refer to the manual that came

with your Access Point to determine its configuration.

Please follow these steps to complete the installation:

1. Connect the Wireless Access Point is shown in the example) to a

Broadband connection (i.e., a Cable modem such as the cable

modem.)

2. Install the DWL-AG520 Wireless PCI Adapter into a desktop

computer on your wireless network. (You can also install the

Wireless Cardbus Adapter into a laptop computer. Please refer to

the Quick Install Guide included with each product.)

3. Check the Device Manager to confirm that the wireless adapter is

installed correctly. Please refer to the Networking Basics section in

this manual entitled: Checking the Installation of the Drivers for
