Introduction

D-Link®, the industry pioneer in wireless networking, introduces a performance breakthrough in wireless connectivity – D-Link AirPlus Xtreme G™ 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-intensive 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.

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.

Before You Begin

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.

Connect to Your Network

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.

Configuration

To configure the DWL-2100AP, use a computer which is connected to the DWL-2100AP with an Ethernet cable. You may use the web-based configuration or the AP Manager software to configure your access point. Please refer to page 52 to use the AP Manager software.

Web Configuration Utility

First, disable the Access the Internet using a proxy server function. To disable this function, go to Control Panel > Internet Options > Connections > LAN Settings and uncheck the enable box.

Open your web browser program such as Internet Explorer. Type the IP address of the DWL-2100AP in the address field (http://192.168.0.50) and press Enter. Make sure that the IP addresses of the DWL-2100AP and your computer are in the same subnet.

After the connection is established, Enter your user name (admin) and your password (leave blank by default). Click OK to continue.

Home

The Home > Wizard screen will appear. Please refer to the Quick Installation Guide for more information regarding the Setup Wizard.

These buttons appear on most of the configuration screens in this section. Please click on the appropriate button at the bottom of each screen after you have made a configuration change.

Apply Clicking Apply will save changes made to the page

Cancel Clicking Cancel will clear changes made to the page

Help Clicking Help will bring up helpful information regarding the page

Restart Clicking Restart will restart the router. (Necessary for some changes.)
