Wireless Basics
D-Link Air 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. Strictly adhering to the
IEEE standard, the D-Link Air wireless family of products will allow you to
access the data you want, when and where you want it. You will be able to
enjoy the freedom that wireless networking delivers.
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.

Wireless Basics

Installation Considerations
Designed to go up to 1,311 feet (approximately 400 meters), the D-Link Air
DCF-660W lets you access your network from virtually anywhere. Keep in
mind, however, that the number, thickness and location 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
(radio frequency) 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 wireless Access
Point and your receiving device (i.e., the DCF-660W) to a minimum -
Each wall or ceiling can reduce your D-Link Air Wireless product’s range
from 3-90 feet (1-30 meters.) Position your Access Points, Residential
Gateways, and computers so that the number of walls or ceilings is
minimized.
2. Be aware of the direct line between Access Points, Residential
Gateways, and computers. 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 position the
Access Points and adapters 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 device’s 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 may generate extreme RF noise.
For the average home, range should not be a problem. If you experience
low or no signal strength in areas of your home that you wish to access,
consider positioning the Access Point in a location directly between the
computers with wireless adapters. Additional Access Points can be
connected to provide better coverage in rooms where the signal does not
appear as strong as desired.

Getting Started
Right out of the box, with its default settings, the DCF-660W will
automatically connect with other D-Link Air products.
On the following pages we will show you an example of two modes of
networking:
Infrastructure – using an Access Point, such as the DWL-
1000AP
Ad-Hoc – directly connecting to another computer, in a peer-to-
peer mode, using a wireless network adapter, such as the DWL-
650 in a laptop computer and the DCF-660W in a PDA.
An Infrastructure network contains an Access Point. The Infrastructure
Network example shown on the following page contains the following D-Link
network devices:
A wireless DHCP Router/Access Point/Print Server - D-Link Air DI-713P
A laptop computer with a wireless network adapter - D-Link Air DWL-650
A desktop computer with an Ethernet adapter - D-Link DFE-530TX+
A desktop computer with a wireless network adapter- D-Link Air DWL-520
A Cable modem - D-Link DCM-200
A PDA with a wireless compact flash adapter - D-Link Air DCF-660W
DHCP stands for Dynamic Host Configuration Protocol.
It is a protocol for assigning dynamic IP addresses “automatically.”
With a DHCP-capable gateway/router, there is no need
to manually assign an IP address.
Please refer to the following sections of this manual for additional information
about setting up a network:
Networking Basics- learn how to check your IP Address; share printers and
files.
Using the Configuration Utility- learn the settings you must use on each
computer in your network for successful communication.
Troubleshooting – learn how to check for the proper installation of the
network adapters’ drivers and other tips for troubleshooting the network.

Getting Started
Setting Up an Infrastructure Network
Please remember that D-Link Air wireless devices are pre-configured to connect
together, right out of the box, with the default settings.
You will need a broadband Internet access (Cable/DSL)
subscription.
Consult with your Cable/DSL provider for proper installation of the
modem.
Connect the modem to a wireless Broadband router (such as the D-
Link Air DI-713P.) See the installation instructions included with the
router.
Install the drivers for the wireless network adapter (such as the D-
Link Air DWL-650) into the laptop computer. See the Quic
k
Installation Guide included with the DWL-650.
If an Ethernet port is available on the router, connect a computer
that is equipped with an Ethernet Network adapter (such as the
DFE-530TX+
)
to the router.
If you have a desktop computer in your network, install the drivers
for the D-Link Air DWL-520 wireless network adapter. See the
Quick Installation Guide included with the DWL-520.
Install the D-Link Air DCF-660W into your PDA. See the Quic
k
Installation Guide included with the DCF-660W. In all the above
installations, the LEDs will light ON to show connection.

Getting Started
Setting up a Wireless Ad Hoc Network
Install a network adapter into one computer. In the example
above, a D-Link Air DWL-120 USB Wireless Network adapter is
installed. A DWL-520 Wireless PCI Adapter could also be
installed in a desktop computer. See the Quick Installation Guid
e
included with the product for installation instructions.
Install a wireless cardbus adapter (such as the DWL-650) into a
laptop computer. See the Quick Installation Guide included with the
network adapter. 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. (See
box below.)
10
Install and configure the DCF-660W. See the Quick Installation
Guide included with the product.
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.
