Introduction
For home users that will not incorporate a RADIUS server in their network, the security
for the DWL-2100AP, used in conjunction with other WPA-compatible 802.11 products,
will still be much stronger than ever before. Utilizing the Pre-Shared Key mode of WPA,
the DWL-2100AP will obtain a new security key every time it connects to the 802.11
network. You only need to input your encryption information once in the configuration
menu. No longer will you have to manually input a new WEP key frequently to ensure
security. With the DWL-2100AP, you will automatically receive a new key every time you
connect, vastly increasing the safety of your communication.
The DWL-2100AP is capable of operating in one of 5 different modes to meet your
wireless networking needs. The DWL-2100AP can operate as an access point, in access
point-to-access point bridging mode, access point-to-multi-access point bridging mode,
repeater, or wireless client mode.
The DWL-2100AP is an ideal solution for quickly creating and extending a wireless local
area network (WLAN) in offices or other workplaces, trade shows and special events.
Unlike most access points, the DWL-2100AP provides data transfers at up to 108 Mbps in
Super G mode when used with other D-Link AirPlus Xtreme G™ products. The 802.11g
standard is backwards compatible with 802.11b devices.
The DWL-2100AP has the newest, strongest, most advanced security features available
today. When used with other 802.11g WPA (WiFi Protected Access) compatible products
in a network with a RADIUS server, the security features include:
WPA:
Wi-Fi Protected Access which authorizes and identifies users based on a
secret key that changes automatically at regular intervals. WPA uses TKIP
(Temporal Key Integrity Protocol) to change the temporal key every 10,000
packets (a packet is a kind of message transmitted over a network.)
This insures much greater security than the standard WEP security. (By
contrast, the previous WEP encryption implementation required the keys
to be changed manually.)
At up to fifteen times the maximum wireless signal rate of previous wireless devices (up
to 108Mbps* in Super G mode), you can work faster and more efficiently, increasing
productivity. With the DWL-2100AP, bandwidth-intensive applications like graphics or
multimedia will benefit significantly because large files are able to move across the
network quickly.
*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput
will vary. Network conditions and environmental factors, including volume of network traffic, bulilding materials
and construction, and network overhead lower actual data throughout rate.”

Features
5 Different Operation modes - Capable of operating in one of five different operation
modes to meet your wireless networking requirements: Access Point, AP-to-AP
Bridging, AP-to-Multi-AP Bridging, Repeater, or Wireless Client.
Better security with WPA. The DWL-2100AP can securely connect to wireless
clients on the network using WPA (Wi-Fi Protected Access) providing a much
higher level of security for your data and communications than has previously
been available. AES is also supported by the DWL-2100AP to maximize the
network security with data encryption.
Compatible with the 802.11b standard to provide a wireless data rate of up to
11Mbps - that means you can migrate your system to the 802.11g standard
on your own schedule without sacrificing connectivity.
Faster wireless networking with the 802.11g standard to provide a wireless data
rate of up to 54Mbps (108Mbps* in Super G mode).
SNMP for Management. The DWL-2100AP is not just fast but it also supports
SNMP v.3 for a better network management. Superior wireless AP manager
software is bundled with the DWL-2100AP for network configuration and firmware
upgrade. Systems administrators can also setup the DWL-2100AP easily with
the Web-based configuration. A D-Link D-View module will be downloadable
for network administration and real-time network traffic monitoring with D-Link
D-View software.

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-use 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 for many users.
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)
Standards-Based Technology
The DWL-2100AP Wireless Access Point utilizes the 802.11b and the 802.11g
standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps* (108Mbps in Super G mode) within the 2.4GHz band, utilizing
OFDM technology.
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
network without noticeable delays.
This technology works by 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. The D-Link
DWL-2100AP will automatically sense the best possible connection speed to ensure
the greatest speed and range possible.
802.11g offers the most advanced network security features available today, including:
WPA , TKIP, AES and Pre-Shared Key mode.
The DWL-2100AP is compatible, in default mode, with the following wireless products:
D-Link AirPlus Xtreme G™ DWL-G650
Wireless Cardbus Adapters used with laptop computers
D-Link AirPlus Xtreme G™
DWL-G520 Wireless PCI cards used with desktop computers
The DWL-2100AP is also interoperable with other 802.11g and 802.11b
standards-compliant devices.

Wireless Basics (continued)
Installation Considerations
The D-Link AirPlus Xtreme G™ DWL-2100AP 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 your product away (at least 3-6 feet or 1-2 meters) from electrical devices
or appliances that generate RF noise.
4
Keep the number of walls and ceilings between the DWL-2100AP and other
network devices to a minimum - each wall or ceiling can reduce your DWL2100AP’s range from 3-90 feet (1-30 meters.) Position your devices so that the
number of walls or ceilings is minimized.
1
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.
2
Building materials can impede the wireless signal - 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.
