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.

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
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 WUA-1340 and
1
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
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 WUA-1340 Wireless Network USB adapters.
On the following pages we will show you an example of an InfrastructureNetwork and an Ad-Hoc Network.
An Infrastructure network contains an access point or router. TheInfrastructure 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

Wireless USB Adapter
Install the D-Link WUA-1340 Wireless USB adapter into
the desktop computer. (See the Quick Inst allation Guide included with
the product.)
Install the D-Link WUA-1340 Wireless USB adapter into
the laptop 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 the Ad-Hoc network.
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 sameIP 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.
