3 Introduction The D-Link AirPlusXtreme G DWL-2000AP
High-Speed Wireless Access Point is a
draft 802.11g high-performance, wireless access point that supports high-speed wireless networking at home, at work or in public places.
The DWL-2000AP is capable of operating in one of 4 different modes to meet your wireless networking needs. The DWL-2000AP can operate as an Access Point; in Access Point-to-Access Point Bridging mode; Access Point-to-Multipoint Bridging mode; or Wireless Client mode.
The DWL-2000AP 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-2000AP provides data transfers at up to 54 Mbps (compared to the standard 11 Mbps) when used with other D-Link AirPlusXtremeG products. The 802.11g standard is backwards compatible with 802.11b products. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 802.11gâ€™s speed when you mix 802.11b and 802.11g devices, but you will not lose the ability to communicate when you incorporate the 802.11g standard into your 802.11b network. You may choose to slowly change your network by gradually replacing the 802.11b devices with 802.11g devices .
In addition to offering faster data transfer speeds when used with other 802.11g products, the DWL-2000AP has the newest, strongest, most advanced security features available today. When used with other 802.11g WPA (WiFi Protected Access) and 802.1x compatible products in a network with a RADIUS SERVER, the security features include: WPA:*
A new security feature, Wi-Fi Protected Access authorizes and identifies users based on a secret key that changes automatically at a regular interval. 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 older WEP encryption required the keys to be changed manually.) 802.1x: Authentication is a first line of defense against intrusion. In the Authentication process the server verifies the identity of the client attempting to connect to the network.Unfamiliar clients would be denied access. * Available Spring 2003 as a free download
Pressing the Reset Button restores the router to its original factory default settings.
Receptor for the Power Ethernet Port Adapter
When connecting to a non-wireless router you will need to use a Cross- Over Cable; when connecting to an Ethernet-enabled computer you will need to use a Straight-Through Cable.
5 LEDs LED stands for Light-Emitting Diode. The DWL-2000AP Wireless Access Point has 3 LEDs as shown below: Power: Solid green light indicates connection LAN: Blinking green light indicates activity

7 Wireless Basics
D-Linkwireless products are based on industry standards to provide easy-to-
use and compatible high-speed wireless connectivity within your home, business
or wherever a wireless network is available. 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 cellular 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.
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 Access Point is a device
that can be used to provide this link.
8 Wireless Basics (continued) 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 â€“ WLANs are easy to set up, manage, change and relocate. Networks that frequently change, both physically and
logically, can benefit from a WLANâ€™s 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. Scalability â€“ 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. Inexpensive solutionâ€“ Wireless network devices are as competitively priced as conventional Ethernet network devices. The DWL-2000AP is compatible with the following wireless products:
! D-Link AirPlus DWL-650+,D-Link AirPlusXtremeG DWL-G650
Wireless Cardbus Adapters used with laptop computers
! D-Link AirPlus DWL-520+, D-Link AirPlusXtremeG DWL-G520
Wireless PCI cards used with desktop computers
9 Wireless Basics (continued) Standards-Based Technology 1
The DWL-2000AP Wireless Access Point utilizes the new 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps 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-2000AP 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 , 802.1x, TKIP 2 , AES and Pre-Shared Key mode. These security
features are explained in more detail in the Introduction and the Features section of this manual.
The DWL-2000AP is backwards compatible with 802.11b devices. This means that if you have an existing 802.11b network, the devices in that network will be compatible with 802.11g devices at speeds of up to 11Mbps in the 2.4GHz range. 1 802.11g standard is scheduled for ratification by IEEE Summer 2003 2 WPA will be available Spring 2003 as a free download
10 Wireless Basics (continued) Installation Considerations The D-Link AirPlus Xtreme G DWL-2000AP 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:
1. Keep the number of walls and ceilings between the DWL-2000AP and
your receiving device (e.g., the DWL-G650 or the DWL-650+) to a minimum
-each wall or ceiling can reduce your D-Link Wireless productâ€™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! 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. 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.
11 Getting Started
There are basically two modes of networking:
! Infrastructure â€“ using an Access Point such as the DWL-2000AP.
