IEEE 802.11g Wireless USB Adapter

WUA-1340

Introduction

The D-Link WUA-1340 Wireless USBAdapter 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.

TheWUA-1340isWi-Fi compliant, meaning that itcanconnectand interoperate

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

and adapters. The WUA-1340 connects to any available USB port on a laptop

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

cradle.With the optionalUSB cradle, the WUA-1340 canbe positioned virtually

anywhereataworkstationtoachievethebestavailable 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 (v10.3x 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 WUA-1340 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 WUA-1340 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 WUA-1340, 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-

useandcompatiblehigh-speedwirelessconnectivitywithinyourhome,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

locationwithinthe operating rangeofthe WLAN. Management decisionsbased

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

ofimplementation. WLANs can operate inlocations whereinstallation 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 WUA-1340 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

dependingonthe types of materialsandbackground 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 WUA-1340 and

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

your WUA-1340’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

oraluminum studs may havea negativeeffecton range.Tryto position

wireless devices and computers with wireless adapters so that the

signalpasses through drywall oropendoorwaysandnotothermaterials.

Getting Started

A wireless router - D-Link AirPlusTM GDI-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 WUA-1340 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.)

Installthe D-Link WUA-1340 Wireless USBadapter into an

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

tion Guide included with the WUA-1340.)

Getting Started (continued)

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

Setting up a Wireless Infrastructure Network

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

assignedanIPaddressof 192.168.0.3 with asubnetmaskof255.255.255.0,

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.

IP Address

Install the D-Link WUA-1340 Wireless USB adapter into

the desktop computer. (See 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 theAd-Hoc network.

Install the D-Link WUA-1340 Wireless USB adapter into

the laptop computer. (See the Quick Installation Guide included with

the product.)
