Introduction

At up to fteen times the maximum wireless signal rate of previous wireless devices (up to 108Mbps* in Super G mode), you can work faster and more efciently, increasing productivity. With the DWL-2100AP, bandwidth-intensive applications like graphics or multimedia will benet signicantly because large les are able to move across the network quickly.

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, access

point-to-multi-point bridging mode with AP function, access point-to-multi-point bridging mode without ap function, repeater, or wireless client mode.

The DWL-2100AP is an ideal solution for quickly creating and extending a wireless local area network (WLAN) in ofces 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:

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 conguration 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.

Wi-Fi Protected Access which authorizes and identies 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.)

*Maximum wireless signal rate derived from IEEE Standard 802.11g specications. Actual data throughput will vary. Network conditions and environmental factors lower

Wireless Basics

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 ofce 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 efciently. Increased mobility and the absence of cabling and

other xed infrastructure have proven to be benecial 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.

People use WLAN technology for many different purposes:

Mobility

within the operating range of the WLAN. Management decisions based on real-time information can signicantly improve worker efciency.

- Productivity increases when people have access to data in any location

Low Implementation Costs - WLANs are easy to set up, manage, change

and relocate. Networks that frequently change can benet 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 ofce.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Scalability - WLANs can be congured in a variety of ways to meet the needs of

specic applications and installations. Congurations 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 DWL-2100AP is compatible, in default mode, with the following wireless products:



D-Link AirPlus Xtreme GTM DWL-G650 Wireless Cardbus Adapters used with laptop computers



D-Link AirPlus XtremeTM 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.

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 specied range of this device, you will be able to transfer large les 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.

Installation Considerations

The D-Link AirPlus Xtreme G

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 the number of walls and ceilings between the DWL-2100AP and other network

devices to a minimum - each wall or ceiling can reduce your DWL-2100AP’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or

ceilings is minimized. 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.

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.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or

appliances that generate RF noise.

Troubleshooting

This Chapter provides solutions to problems that can occur during the installation and

operation of the DWL-2100AP Wireless Access Point. We cover various aspects of the network setup, including the network adapters. Please read the following if you are

having problems.

Note: It is recommended that you use an Ethernet connection to

congure the DWL-2100AP Wireless Access Point.

1. The computer used to congure the DWL-2100AP cannot access the conguration menu.

Check that the Ethernet LED on the DWL-2100AP is ON. If the LED



is not ON, check that the cable for the Ethernet connection is securely



inserted.



Check that the Ethernet adapter is working properly. Please see item

3 (Check that the drivers for the network adapters are installed



properly) in this Troubleshooting section to check that the drivers are

loaded properly.

Check that the IP address is in the same range and subnet as the



DWL-2100AP. Please see Checking the IP Address in Windows XP



in the Networking Basics section of this manual.

Note: The IP address of the DWL-2100AP is 192.168.0.50. All the computers on the network must have a unique IP address in the same range, e.g., 192.168.0.x. Any computers that have identical IP addresses will not be visible on the network. They must all have the same subnet mask, e.g., 255.255.255.0

Do a Ping test to make sure that the DWL-2100AP is responding. Go



to Start>Run>Type Command>Type ping 192.168.0.50. A successful ping will show four replies.

Note: If you have changed the default IP address, make sure to ping the correct IP address assigned to the DWL-2100AP.

Troubleshooting (continued)

2. The wireless client cannot access the Internet in Infrastructure mode.

Make sure the wireless client is associated and joined with the correct access point. To

check this connection: Right-click on the local area connection icon in the taskbar>

select View Available Wireless Networks. The Connect to Wireless Network screen

will appear. Please make sure you have selected the correct available network, as

shown in the illustration below.

• Go to Start

• Right-click on My Computer

• Click Properties

default

Check that the IP address assigned to the wireless adapter is within the s ame IP



address range as the access point and gateway. (Since the DWL-2100AP has



an IP address of 192.168.0.50, wireless adapters must have an IP address in the same range, e.g., 192.168.0.x. Each device must have a unique IP address;

no two devices may have the same IP address. The subnet mask must be the same for all the computers on the network.) To check the IP address assigned

to the wireless adapter, double-click on the local area connection icon in the taskbar > select the Support tab and the IP address will be displayed.

(Please refer to Checking the IP address in the Networking Basics section of this manual.)

If it is necessary to assign a static IP address to the wireless adapter, please



refer to the appropriate section in Networking Basics. If you are entering a DNS



server address you must also enter the default gateway address. (Remember that if you have a DHCP-capable router , you will not need to assign a static IP

address. See Networking Basics: Assigning a Static IP Address.)

Troubleshooting (continued)

2. The wireless client cannot access the Internet in the Infrastructure mode (continued).

Check to make sure that the router in your network is functioning properly



by pinging it. If the router is not functioning properly, it will not connect to the Internet. If you need to nd out how to ping network devices, please refer to

Checking the Wireless Connection by pinging in the Networking Basics section of this manual.

Check to make sure that the DNS server in your network is functioning



properly by pinging it. If the DNS server is not functioning properly, you may be unable to access the Internet. Typically, your ISP (Internet Service Provider) will be able to give you the DNS server information.

3. Check that the drivers for the network adapters are installed properly.

You may be using different network adapters than those illustrated here, but this procedure will remain the same, regardless of the type of network adapters you are using.

4. What variables may cause my wireless products to lose reception?

D-Link products let you access your network from virtually anywhere you want. However, the positioning of the products within your environment will affect the wireless range. Please

refer to Installation Considerations in the Wireless Basics section of this manual for further

information about the most advantageous placement of your D-Link wireless products.

5. Why does my wireless connection keep dropping?

Antenna Orientation- Try different antenna orientations for the DWL-2100AP. Try to



keep the antenna at least 6 inches away from the wall or other objects.

If you are using 2.4GHz cordless phones, X-10 equipment or other home security



systems, ceiling fans, and lights, your wireless connection will degrade dramatically

or drop altogether. Try changing the channel on your router, access point and wire-

less adapter to a different channel to avoid interference.

Keep your product away (at least 3-6 feet) from electrical devices that generate



RF noise, like microwaves, monitors, electric motors, etc.

When deploying several access points and wireless devices, please make sure that



access points in close proximity do not have overlapping channels. Nearby access

points should be assigned channels that are at least 4 channels apart to prevent

interference. For example, with a group of 3 access points you could assign the rst

to channel 1, the second to channel 6, and the third to channel 1 1.

6. Why can’t I get a wireless connection?

If you have enabled encryption on the DWL-2100AP, you must also enable encryption

on all wireless clients in order to establish a wireless connection.

The encryption settings are: 64-, 128-, or 152-bit. Make sure that the encryption



bit level is the same on the access point and the wireless client.

Make sure that the SSID on the access point and the wireless client are exactly



the same. If they are not, wireless connection will not be established.



Move the DWL-2100AP and the wireless client into the same room and then



test the wireless connection.

Disable all security settings. (WEP, MAC Address Control)



Troubleshooting (continued)

6. Why can’t I get a wireless connection? (continued)

Turn off your DWL-2100AP and the client. Turn the DWL-2100AP back on again,



and then turn on the client. Make sure that all devices are set to Infrastructure mode.



Check that the LED indicators are indicating normal activity. If not, check that



the AC power and Ethernet cables are rmly connected.

Check that the IP address, subnet mask, and gateway settings are correctly



entered for the network. If you are using 2.4GHz cordless phones, X-10 equipment or other home se-



curity systems, ceiling fans, and lights, your wireless connection will degrade dramatically or drop altogether. Try changing the channel on your DWL-2100AP, and on all the devices in your network to avoid interference.

Keep your product away (at least 3-6 feet) from electrical devices that generate



RF noise, like microwaves, monitors, electric motors, etc.

7. I forgot my encryption key.

Reset the DWL-2100AP to its factory default settings and restore the other



devices on your network to their default settings. You may do this by pressing the Reset button on the back of the unit. You will lose the current conguration

settings.
