3 Introduction TM 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 802.11gs 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 4 Connections Pressing the Reset Button restores the router to its original factory default settings. The LAN Port is Auto-MDI/MDIX. You can insert either a Straight-through or a Cross-over Ethernet cable in this port in order to connect the DWL-

2000AP to a switch on the local network. Receptor for the Power Adapter 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 on the Ethernet Port; solid green light indicates connection WLAN: Blinking green light indicates wireless activity;

solid green light indicates connection 6 Features

4 Different Operation modes - Capable of operating in one of four different operation modes to meet your wireless networking requirements: Access Point; AP-to-AP Bridging; AP-to-Multipoint Bridging; and Wireless Client. Faster wireless networking with the draft 802.11g standard to provide a wireless data rate of up to 54Mbps

! 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. Better security with WPA* and 802.1x*

WPA* (Wi Fi Protected Access) authorizes and identifies users based on a secret key that changes automatically at a regular interval

! TKIP (Temporal Key Integrity Protocol), in conjunction with a RADIUS SERVER, changes the temporal key every 10,000 packets, ensuring greater security Pre Shared Key mode means that the home user, with-

out a RADIUS SERVER, will obtain a new security key every time he or she connects to the network, vastly im-

proving the safety of communications on the network.

802.1x* Authentication in conjunction with the RADIUS SERVER verifies the identity of would be clients

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 WLANs are easy to set up, manage, change and relocate. Networks that frequently change, both physically and logically, can benefit from a 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. 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. Inexpensive solution 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 AirPlus XtremeG DWL-G650 Wireless Cardbus Adapters used with laptop computers D-Link AirPlus DWL-520+, D-Link AirPlus XtremeG DWL-G520 Wireless PCI cards used with desktop computers 9 Wireless Basics (continued) 1 Standards-Based Technology 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, 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. 2 3 1 2 3 802.11g standard is scheduled for ratification by IEEE Summer 2003 WPA will be available Spring 2003 as a free download 802.1x 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 products 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 On the following pages we will show you an example of an Infrastructure Network incorporating the DWL-2000AP.

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.) 41 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 find 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. If you need to find out how to ping network devices, please refer to Checking the Wireless Connection by pinging in the Networking Basics section of this manual. 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.

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 advanta-

geous placement of your D-Link wireless products. 5. Why does my wireless connection keep dropping?

Antenna Orientation- Try different antenna orientations for the DWL-

2000AP. 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 Wireless 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 first to channel 1, the second to channel 6, and the third to channel 11. 6. Why cant I get a wireless connection?

If you have enabled Encryption on the DWL-2000AP, you must also enable en-

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

The Encryption settings are: 64 or 128bit. 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 estab-

lished. Move the DWL-2000AP and the wireless client into the same room and then test the wireless connection. Disable all security settings. (WEP, MAC Address Control) 44 Troubleshooting (continued) 6. Why cant I get a wireless connection? (continued)

Turn off your DWL-2000AP and the client. Turn the DWL-2000AP 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 firmly connected. Check that the IP Address, subnet mask, and gateway settings are cor-

rectly entered for the network. 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 DWL-2000AP, and on all the devices in your network to avoid inter-

ference. 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-2000AP 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 configuration settings. 45 Troubleshooting (continued) 8. Resetting the DWL-2000AP to Factory Default Settings After you have tried other methods for troubleshooting your network, you may choose to Reset the DWL-2000AP to the factory default settings. Reset To hard-reset the D-Link DWL-2000AP to the Factory Default Settings, please do the following:

Locate the Reset button on the back of the DWL-2000AP Use a paper clip to press the Reset button Hold for about 5 seconds and then release
