A laptop or notebook computer with an available 32-bit

Cardbus slot Windows XP, Windows 2000, Windows Me, or Windows 98SE At least 128 MB of memory and a 500 MHz processor An 802.11a, 802.11b or 802.11g Access Point (for Infrastruc-

ture Mode) or another 802.11a, 802.11b, or 802.11g wireless adapter (for Ad-Hoc; Peer-to-Peer networking mode).

3 Introduction TM The D-Link Air Xpert DWL-AG650 Tri-mode Dualband Wireless Cardbus Adapter is an 802.11a/802.11b/draft 802.11g high-performance, wireless adapter that supports high-

speed wireless networking at home, at work or in public places. Featuring a breakthrough all-in-one tri-mode dualband design, the new D-Link Air Xpert DWL-AG650 is a next generation laptop PC adapter that connects to 802.11a (in the 5GHz band) and draft 802.11g networks (in the 2.4GHz band) at 54 Mbps and 802.11b networks (in the 2.4GHz band) at 11Mbps. When used with other 802.11a or 802.11g devices, the DWL-AG650 will achieve data transfer rates of up to 54Mbps. 802.11b devices will communicate at 11Mbps. In addition to offering faster data transfer speeds when used with other 802.11a or draft 802.11g products, the DWL-AG650 has the newest, most advanced security features available today, using the draft 802.11i security standard. These additional security features are optional. You may choose to continue using the familiar WEP security, or you may not wish to utilize security features at all. However, if you do choose to use the DWL-AG650s powerful security features with other WPA (WiFi Protected Access) and 802.1x compatible products in a network with a RADIUS server, the security features will 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 ensures 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. Users that choose not to incorporate a RADIUS server in their network may also use the optional enhanced security features, or they may wish to continue using the standard WEP security, or they may choose to use no security at all. However, if you do wish to experience the enhanced security of the DWL-AG650 in conjunction with other draft 802.11i compatible products, without a RADIUS server, the Pre Shared Key mode of WPA will assign a new security key every time the DWL-AG650 connects to the draft 802.11i Access Point. If you choose to enable the enhanced security features of the DWL-AG650, you need only to input your encryption information once in the configuration menu. No longer will you have to manually change the WEP key to ensure security -

with the DWL-AG650, you will automatically receive a new key every time you connect, vastly increasing the safety of your communications.

*WPA will be available Q3 2003 as a driver download 4 Features

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 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. 6 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 can benefit 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 office. Inexpensive Solution Wireless network devices are as competitively priced as conventional Ethernet network devices. 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. The DWL-AG650 is compatible with the following wireless products:

D-Link AirPro DWL-A650, D-Link AirPlus DWL-650+, D-Link AirPlus Xtreme G DWL-G650, D-Link AirPro DWL-AB650 Wireless Cardbus Adapters used with laptop computers D-Link AirPro DWL-A520 and D-Link AirPlus DWL-520+, D-Link AirPlus Xtreme G DWL-G520, D-Link AirXpert DWL-AG520, and D-Link AirPro DWL-AB520 Wireless PCI cards used with desktop computers D-Link AirPlus DWL-900AP+, D-Link AirPlus Xtreme G DWL-

2000AP and D-Link AirXpert DWL-7000AP Wireless Access Points

! D-Link AirPlus DI-614+, D-Link AirPlus Xtreme G DI-624 and D-Link AirXpert DI-774 Wireless Broadband Routers 7 Wireless Basics (continued) 1 Standards-Based Technology 1 The DWL-AG650 Wireless Cardbus Adapter utilizes the 802.11a, 802.11b and draft 802.11g standard. The IEEE draft 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. The 802.11a standard also increases the data rate up to 54 Mbps, but within the 5GHz band. Both 802.11a and 802.11g utilize 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-AG650 will automatically sense the best possible connection speed to ensure the greatest speed and range possible. The DWL-AG650 offers the most advanced network security features available today, including: WPA , 802.1x and AES hardware support. In addition to its compatibility with 802.11g and 802.11a devices, the DWL-

AG650 is compatible with 802.11b devices. This means that if you have an existing 802.11b network, or a network with a mixture of 802.11g, 802.11a and 802.11b, the devices in that network will be compatible with the DWL-AG650. 2 3 1 2 3 802.11g standard is scheduled for ratification in Q3 2003 WPA will be available Q3 2003 as a driver or firmware download Available soon as a firmware and driver update 8 Wireless Basics (continued) TM Installation Considerations The D-Link Air Xpert DWL-AG650 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-AG650 and other network devices to a minimum - each wall or ceiling can reduce your D-Link wireless products range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. 2. 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. 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 may generate extreme RF noise. 9 Getting Started There are basically two modes of networking:

Infrastructure using an Access Point, or Wireless Router, such as the DWL-7000AP. Ad-Hoc directly connecting to another computer, for peer-to-

peer communication, using wireless network adapters on each computer, such as two or more DWL-AG650 wireless network Cardbus adapters. On the following pages we will show you an example of an Infrastructure Network and an Ad-Hoc Network. An Infrastructure network contains an Access Point or a Wireless Router. The Infrastructure Network example shown on the following page contains the following D-Link network devices (your existing network may be comprised of other devices):

Make sure that the SSID on the DWL-AG650 Cardbus adapter is exactly the same as the SSID on the Access Point or wireless Router. Move the DWL-AG650 and Access Point or wireless Router into the same room and then test the wireless connection. Disable all security settings. (WEP, MAC Address Control, AES) Make sure that the Access Point/Router is not locked down to a different frequency Turn off your Access Point and the computer with the DWL-AG650. Turn on the Access Point, and then turn on the computer with the DWL-AG650. Refresh the DWL-AG650 Utility 3. The DWL-AG650 Power and Link lights are not on.

Check to see if the DWL-AG650 Cardbus adapter is firmly inserted into the Cardbus slot of your laptop computer. 4. I forgot my Encryption key.

Reset the Access Point to its factory default settings and restore the DWL-AG650 Wireless Cardbus Adapter to the factory default settings. 5. The computer does not recognize the DWL-AG650 Wireless Adapter.

Make sure that the DWL-AG650 Wireless Adapter is properly seated in the computers Cardbus slot. If Windows does not detect the hardware upon insertion of the adapter, make sure to completely remove drivers that were previously loaded. To remove the drivers, do the following:

35 Troubleshooting A. Under Tools> select Folder Options> select View

> under Hidden files and folders > select Show hidden files and folders B. Uncheck Hide extension for known file types > click on Apply C. Search for previously loaded driver files. Remove these files from the INF and SYSTEM32 (DRIVERS) folders in the Windows directory. Note: Windows XP and Windows 2000 will rename .inf files that have not received WHQL certification into oem.inf files (e.g., oem1.inf). 6. The computer with the DWL-AG650 installed is unable to connect to the wireless network and/or the Internet.

Check that the LED indicators for the broadband modem are indicating normal activity. If not, there may be a problem with the broadband connection. Check that the LED indicators on the wireless router are functioning properly. If not, check that the AC power and Ethernet cables are firmly connected. Check that the IP Address, subnet mask, gateway, and DNS settings are correctly entered for the network. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on the settings for the wireless clients and access points. The SSID factory default setting for the D-Link products is default. (Double-click on the WLAN icon in the taskbar. The Link Info screen will display the SSID setting). In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please note that it might be necessary to set up one client to establish a BSS (Basic Service Set) and wait briefly before setting up other clients. This prevents several clients from trying to establish a BSS at the same time, which can result in multiple singular BSSs being established, rather than a single BSS with multiple clients associated to it. 36 Troubleshooting

Check that the Network Connection for the wireless client is configured properly. Select AP (Infrastructure) when connecting to an access point and select Ad-Hoc mode when connecting without an access point. Double-click on the WLAN icon in the taskbar > click on Configuration to change the settings for the wireless adapter. If Security is enabled, make sure that the correct encryption keys are entered on both the DWL-AG650 and the access point. Double-

click on the WLAN icon in the taskbar > click Encryption. Check to see that the key selected is set to the same key as other devices on the network.

! If Turbo mode is enabled, make sure that Turbo mode is enabled on all Turbo mode compatible devices in your network, in order to communicate. 7. How can I troubleshoot distance issues using the DWL-AG650.
