Introduction

The D-Link AirPlus G DWL-G122 Wireless USB Adapter is a convenient Plug

& Play USB 2.0 solution that brings wireless networking to your laptop or desktop PC.

With transfer rates up to 54Mbps you can connect to a wireless network at

home, at the office or at any wireless hotspot. Now you can stay connected

wherever you are and wherever you go.

The DWL-G122 is Wi-Fi compliant, meaning that it can connect and interoperate

with other 802.11b or 802.11g Wi-Fi-compliant wireless routers, access points

and adapters. The DWL-G122 connects to any available USB port on a laptop

or desktop Windows and Macintosh-based computer and also includes a USB

cradle. With the optional USB cradle, the DWL-G122 can be positioned virtually

anywhere at a workstation to achieve the best available wireless signal reception

- whether that workstation is in your office, on your deck or patio, by the pool, at

the local coffee shop, or in an airport terminal while waiting to board your next

flight.

The adapter works with Apple Mac OS X (v10.2x or later) Jaguar, Microsoft

Windows XP, Windows 2000 and other Windows operating systems to ensure

that you’ll be up and running on a wireless network in just a matter of seconds.

Using its default settings, the DWL-G122 automatically connects to other

D-Link Air or AirPlus wireless products as soon as it’s active.

In addition to featuring 64- or 128-bit WEP encryption, the DWL-G122 offers

the added security of WPA(Wi-Fi Protected Access)/WPA2 when used with

other WPA / WPA2 devices in a network with a RADIUS server.

For home users that will not incorporate a RADIUS server in their network, the

security for the DWL-G122, used in conjunction with other WPA-compatible

802.11 products, will still be much stronger than ever before when you use the

Pre- Shared Key mode of WPA / WPA2.

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 Ethernet adapter cards.

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 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 to many users.

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.

Inexpensive Solution - Wireless network devices are as competitively priced

as conventional Ethernet network devices.

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.

Installation Considerations

The DWL-G122 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:

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-G122 and

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

your DWL-G122’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.

Getting Started

A wireless router - D-Link AirPlusTM G DI-524

A laptop computer with a D-Link AirPlus G DWL-G122

A desktop computer with a D-Link AirPlus G DWL-G120

A cable modem - D-Link DCM-201

There are basically two modes of networking:

Infrastructure – using an access point or router, such as the DI-624.

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-G122 Wireless Network USB 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):

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 AirPlus G DWL-G122 Wireless USB adapter into an

available USB port on your desktop computer. (See the Quick Installa-

tion Guide included with the DWL-G122.)

Getting Started (continued)

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

Getting Started (continued)

Setting up a Wireless Ad-Hoc Network

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.

2. What variables may cause my wireless products to lose reception?

D-Link products let you access your network from virtually anywhere you want.

However, the positioning of the products within your environment will affect the

wireless range. Please refer to Installation Considerations in the Wireless

Basics section of this manual for further information about the most advanta-

geous placement of your D-Link wireless products.

3. Why does my wireless connection keep dropping?

4. Why can’t I get a wireless connection?

If you have enabled encryption on the DWL-G122, you must also enable en-

cryption on all wireless devices in the network in order to establish a wireless

connection.

If you are using 2.4GHz cordless phones, X-10 equipment or other home

security systems, ceiling fans, and lights, your wireless connection will

degrade dramatically or drop altogether. Try changing the channel on

your router, access point and wireless adapter to a different channel to

avoid interference.



Keep your product away (at least 3-6 feet) from electrical devices that

generate RF noise, like microwaves, monitors, electric motors, etc.



The encryption settings are: 64- or 128-bit. Make sure that the encryp-

tion bit level is the same on the router and the DWL-G122.



Make sure that the SSID on the wireless router (if you have one in your

network) and the DWL-G122 are exactly the same. If they are not, wire-

less connection will not be established. The default SSID is default.

Limited Warranty: D-Link warrants that the hardware portion of the D-Link products described

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

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

•Hardware (excluding 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.

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)

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.
