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 802.1 1b 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.

Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to­use 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.

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.

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.

Wireless Basics (continued)

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 the number of walls and ceilings between the DWL-G122 and

1

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

2

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.

3

Building materials can impede the wireless signal - a solid metal door
or aluminum studs may have a negative effect on range. T ry to position
wireless devices and computers with wireless adapters so that the
signal passes through drywall or open doorways and not other materials.

4

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.

Getting Started

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):

A wireless router - D-Link AirPlus
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

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.

TM

IP Address

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.

Troubleshooting (continued)

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 product s 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 advanta­geous placement of your D-Link wireless products.

3. Why does my wireless connection keep dropping?

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 dif ferent 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.

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

If you have enabled encryption on the DWL-G122, you must also enable en­cryption on all wireless devices in the network in order to establish a wireless
connection.

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, wire­less connection will not be established. The default SSID is default.

Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited
warranty for its product only to the person or entity that originally purchased the product from:

• D-Link or its authorized reseller or distributor and

• Products purchased and delivered within the fifty states of the United States, the District of

Columbia, U.S. Possessions or Protectorates, U.S. Military Installations, addresses with an
APO or FPO.

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
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.

Limited Software Warranty: D-Link warrants that the software portion of the product (“Software”)
will substantially conform to D-Link’s then current functional specifications for the Software, as set forth
in the applicable documentation, from the date of original retail purchase of the Software for a period of
ninety (90) days (“Warranty Period”), provided that the Software is properly installed on approved
hardware and operated as contemplated in its documentation. D-Link further warrants that, during the
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 non­conforming 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.

Non-Applicability of Warranty: The Limited Warranty provided hereunder for hardware and software
of D-Link’s products will not be applied to and does not cover any refurbished product and any product
purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the sellers,
or the liquidators expressly disclaim their warranty obligation pertaining to the product and in that case,
the product is being sold “As-Is” without any warranty whatsoever including, without limitation, the
Limited Warranty as described herein, notwithstanding anything stated herein to the contrary.
