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. Strictly adhering to the IEEE
standard, the D-Link wireless family of products will allow you to securely
access the data you want, when and where you want it. You will be able to
enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that
transmits and receives data with radio signals instead of wires. Wireless
LANs are used increasingly in both home and office environments, and
public areas such as airports, coffee shops and universities. Innovative ways

more efficiently. Increased mobility and the absence of cabling and other
fixed infrastructure have proven to be beneficial for 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.
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 Router is a
device used to provide this link.
People use wireless LAN 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 (Wireless Local Area Networks)
are easy to set up, manage, change and relocate. Networks that frequently
change, both physically and logically, can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring
may be impractical.
Installation Speed and Simplicity - Installing a wireless LAN system
can be fast and easy and can eliminate the need to pull cable through walls
and ceilings.
Network Expansion - Wireless technology allows the network to go where
wires cannot go.
Scalability – Wireless Local Area Networks (WLANs) can be configured in
a variety of topologies 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)
The DI-754 is compatible with other D-Link AirPro 802.11a products, which
include:
♦5GHz Wireless Cardbus Adapters used with laptop computers
(DWL-A650)
♦5GHz Wireless PCI Adapters used with desktop computers
(DWL-A520)
The DI-754 is also compatible with the D-Link AirPlus 802.11b wireless family
(when you install the DWL-650+ into the expansion slot), which includes:
♦Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop
computers (DWL-650+)
♦Enhanced 2.4GHz Wireless PCI cards used with desktop computers
(DWL-520+)
Standards-Based Technology
The versatile DI-754 Wireless Broadband Router integrates both 802.11a and
optional (with D-Link DWL-650+) 802.11b standards into a single unit.
The IEEE 802.11a standard designates thatdevices may operateatan optimal
data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) This means that in
most environments, within the specified range of this device, you will be able to
transfer large files quickly or even watch a movie in MPEG format over your
networkwithout noticeable delays.This technology worksby transmitting high-
speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency
Division Multiplexing) technology. OFDM works by splitting the radio signal
into multiple smaller sub-signals that are then transmitted simultaneously at
different frequencies to the receiver. OFDM reduces the amount of crosstalk
(interference) in signal transmissions. D-Link AirPro 802.11a products will
automatically sense the best possible connection speed to ensure the greatest
speed and range possible.
Based on the IEEE 802.11b standard (when the optional D-Link DWL-650+ is
installed in the expansion slot), the DI-754 is also interoperable with existing
compatible 2.4GHz wireless technology with data transfer speeds of up to
22Mbps(with the D-Link AirPlusfamilyof wireless devices),as wellasstandard
802.11b technology (the D-Link Air family of wireless devices), with speeds of
up to 11Mbps.

Installation Considerations
The D-Link AirPro DI-754 lets you access your network, using a wireless
connection, 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 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:
1. Keep the number of walls and ceilings between the DI-754 and your
receiving device (e.g., the DWL-A650 or the DWL-650+) to a minimum -
each wall or ceiling can reduce your D-Link AirPro Wireless product’s
range from 3-90 feet (1-30 meters.) Position your receiving devices so
that the number of walls or ceilings is minimized.
2. Be aware of the direct line between routers 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 make sure that devices are positioned 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 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.

With a single IP Address from your Broadband Internet Service provider you
can share the Internet with all the computers on your local network, without
sacrificing speed or security, using D-Link DI-754 Wireless Router.
Getting Started
An Infrastructure wireless network contains an Access Point. (Note: The
DI-754 has a built-in 802.11a Access Point.) The Infrastructure Network
example, shown here, contains the following D-Link network devices:
A wireless Router - D-Link AirPro DI-754
A laptop computer with a wireless adapter - D-Link AirPro DWL-A650 or
AirPlus DWL-650+
A desktop computer with a wireless adapter - D-Link AirPro DWL-A520 or
AirPlus DWL-520+
A Cable modem - D-Link DCM-200
If you need to assign 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.
IP ADDRESS
Note: If you are using a DHCP-capable router in your network setup,
such as the DI-754, you will not need to assign a static IP Address.
Right out of the box, with its default settings, the DI-754 will
connect with other D-Link AirPro products.
Note: to utilize the 802.11b connection to your network, please
install the D-Link DWL-650+ into the slot on the back of the DI-
754. Please make sure that the DWL-650+ is fully inserted into
the slot. (See the Quick Installation Guide for the DWL-650+.)
