Product Overview

5DWL-2100AP User Manual
Introduction
D-Link®, the industry pioneer in wireless networking, introduces a performance breakthrough in wireless
connectivity – D-Link AirPlus Xtreme GTM series of high-speed devices now capable of delivering transfer
rates up to 15x faster than the standard 802.11b with the new D-Link 108G.With the new AirPlus Xtreme
G DWL-2100AP Wireless Access Point, D-Link sets a new standard for wireless access points.
With the D-Link 108G enhancement, the DWL-2100AP can achieve wireless speeds up to 108Mbps* in
a pure D-Link 108G environment through the use of new wireless technologies such as Packet Bursting,
Fast Frame, Compression & Encryption, and Turbo mode.These technologies enable a throughput high
enough to handle video/audio streaming and future bandwidth-intense applications. The DWL-2100AP
Wireless Access Point also supports SNMP v.3 for better network management with the provided Wireless
AP Manager software that manages network configuration and firmware upgrades. For Enterprise
networks, the DWL-2100AP supports network administration and real-time network traffic monitoring
via D-Link’s D-View Network Management software.
The DWL-2100AP features five modes: a Wireless Access Point, WDS with Access Point, WDS, a
Repeater for range extension, or as a AP Client. The WDS feature makes the DWL-2100AP an ideal
solution for quickly creating and extending a wireless local area network (WLAN) in offices or other
workplaces, or even at hotspots.
The DWL-2100AP Wireless Access Point comes with a detachable antenna utilizing a reverse SMA
connector. By simply attaching a D-Link wireless antenna, you can increase the wireless range of the
DWL-2100AP.
Wireless security is addressed as the DWL-2100AP Wireless Access Point uses WPA (Wi-Fi Protected
Access) and 802.1X authentication to provide a higher level of security for data communication amongst
wireless clients.The DWL-2100AP is also fully compatible with the IEEE 802.11b and 802.11g standards.
With great manageability, versatile operation modes, solid security enhancement, the cost-effective
D-Link DWL-2100AP Wireless Access Point provides the ultra-fast 108Mbps* speed and everything else
a network professional dreams of.
* 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, building
materials and construction, and network overhead, lower actual data throughput rate. Environmental
factors will adversely affect wireless signal range.

6DWL-2100AP User Manual
Features and Benefits
Faster Wireless Networking Able to achieve a maximum wireless signal rate of up to
108Mbps*, increased speeds means increased productivity.
With the DWL-2100AP in your home or business, colleagues,
friends, or family can communicate with one another in
real-time to download large files or to smoothly stream MPEG
videos.
The DWL-2100AP Wireless Access Point gives you the freedom
of wireless networking at D-Link 108G speeds that save you time,
money, and make your wireless networking experience more
enjoyable.
SNMP Management The DWL-2100AP is not only fast but it also supports SNMP v.3
for better network management. A Wireless AP Manager software
is available with the DWL-2100AP for network configuration
and firmware upgrades via a web-based configuration utility.
For Enterprise networks, the DWL-2100AP supports network
administration and real-time network traffic monitoring via D-Link’s
D-View Network Management software.
Better Security with 802.1X and WPA With the DWL-2100AP, wireless clients can securely connect
to the network using WPA (Wi-Fi Protected Access) and 802.1X
authentication providing a much higher level of security for your
data communication. AES (Advanced Encryption Standard) is also
supported by the DWL-2100AP to maximize the network security
with data encryption.
Five Different Operating Modes

8DWL-2100AP User Manual
Installation Considerations
D-Link Air lets you access your network from anywhere you want. However, keep in mind, that range
is limited by the number of walls, ceilings, or other objects that the wireless signals must pass through.
Typical ranges vary depending on the types of materials and background RF 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 to a minimum - Each wall or ceiling can rob your
D-Link Wireless product of 3-90 ft. of range. 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, routers, and computers - A wall that is
1.5 feet thick, at a 45 degree angle, appears to be almost 3 feet thick. At a 2-degree angle it
looks over 42 feet thick. Try to make sure that the access point and adapters 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 access points, routers, and computers so that the
signal passes through drywall or open doorways and not other materials.
4. Make sure that the 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) from electrical devices that generate RF noise,
like microwaves, monitors, electric motors, UPS units, etc.
6. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans,
lights, and home security systems), your wireless connection will degrade dramatically
or drop completely. Anything using the 2.4Ghz frequency will interfere with your wireless
network.
Installation

9DWL-2100AP User Manual
It’s best to use a computer (with an Ethernet adapter) that is connected to a switch or router for configuring the
DWL-2100AP. The default IP address for the DWL-2100AP is 192.168.0.50 with a Subnet Mask of
255.255.255.0.
You will need to assign your computer a Static IP address within the same range as the DWL-2100AP’s
IP address for the purpose of configuring the DWL-2100AP. See the Appendix if you need assistance in
assigning a Static IP address for your network adapter.
Before You Begin
A. First, connect the power adapter to the receptor at the back panel of the DWL-2100AP and then plug
the other end of the power adapter to a wall outlet or power strip. The Power LED will turn ON to indicate
proper operation.
B. Insert one end of the cable to the Ethernet port on the back panel of the DWL-2100AP and the other
end of the cable to your network (switch or router).
Note: You also have the option of connecting the DWL-2100AP directly to the computer
that will be used for configuration. The Link LED light will illuminate to indicate a proper
Ethernet connection. (Note: The Ethernet Port on the DWL-2100AP is Auto-MDI/MDIX.
Meaning you can use a straight-through or crossover Ethernet cable to connect to the Ethernet port on
the DWL-2100AP.)
C. The DWL-G650 Wireless Cardbus Adapter and the DWL-G520Wireless PCI Adapter will connect, out
of the box, with the DWL-2100AP, using their default wireless settings. Computers with 802.11b wireless
adapters can also connect to the DWL-2100AP.

WDS with AP
In WDS with AP mode, the DWL-2100AP wirelessly connects multiple networks, while still functioning
as a wireless AP. WDS (Wireless Distribution System) allows access points to communicate with one
another wirelessly in a standardized way. It can also simplify the network infrastructure by reducing the
amount of cabling required. Basically the access points will act as a client and an access point at the
same time.
