4IntroductionThe D-Link AirPlusXtremeG DWL-G650 Wireless Cardbus Adapter is an enhanced802.11g high-performance, wireless adapter that supports high-speed wireless networkingat home, at work or in public places.Unlike most network cards, the DWL-G650 provides speeds of up to 54 Mbps (comparedto the standard 11 Mbps) when used with other D-Link AirXtremeG products. The 802.11gstandard is backwards compatible with 802.11b products. This means that you do notneed to change your entire network to maintain connectivity. You may sacrifice some of802.11g’s speed when you mix 802.11b and 802.11g devices, but you will not lose theability to communicate when you incorporate the 802.11g standard into your 802.11bnetwork. You may choose to slowly change your network by replacing the 802.11bdevices with 802.11g devices gradually.In addition to offering faster data transfer speeds when used with other 802.11g products,the DWL-G650 has the newest, strongest, most advanced security features availabletoday. When used with other 802.11g WPA (WiFi Protected Access) and 802.1xcompatible products in a network with a radius server, the security features include:WPA: A new security feature, Wi-Fi Protected Access authorizes and identifies usersbased on a secret key that changes automatically at a regular interval. (Bycontrast, the older WEP encryption required the keys to be changed manually.)802.1x: Authentication is a first line of defense against intrusion. In theAuthentication process the server verifies the identity of the client attemptingto connect to the network. Unfamiliar clients would be denied access.TKIP: Temporal Key Integrity Protocol changes the temporal key every 10,000packets ( a packet is a kind of message transmitted over a network.) Thisinsures much greater security than the standard WEP security.AES: Advanced Encryption Standard offers much larger key sizes. At 128, 192,or 256 bits, the AES keys are much stronger than the old WEP standard of56 bits. It could take 149 trillion years to crack the code of an AES key, asopposed to 1 second to crack an old WEP key.For home users that will not incorporate a radius server in their network, the security forthe DWL-G650, used in conjunction with other 802.11g products, will be much strongerthan ever before. Utilizing the Pre Shared Key mode the DWL-G650 will obtain a newsecurity key every time it connects to the 802.11g network. You only need to input yourencryption information once in the configuration menu. No longer will you have to manuallyinput a new WEP key frequently to ensure security, with the DWL-G650, you willautomatically receive a new key every time you connect, vastly increasing the safety ofyour communications.TM
5The DWL-G650 is compatible with existing 802.11b devices such as the D-Link Air,AirPlus and AirPro family of products including the DWL-520, DWL-520+ and theDWL-AB520 Wireless PCI Adapter, the DI-714 Wireless Router/Access Point and theDWL-120 Wireless USB Adapter. (When used with 802.11b devices, the DWL-G650will reach speeds at up to 11Mbps.)It is an ideal way to connect one laptop computer to a Wireless Local Area Network(WLAN.) After completing the steps outlined in the Quick Installation Guide(included in the package) you will have the ability to share information and resources,such as files and printers, and take full advantage of a “connected” environment forwork or play!The DWL-G650 includes software drivers for the most popular Microsoft Windowsoperating systems (Windows XP, Windows 2000, Windows Me, Windows 98) and canbe integrated into a larger network, running, in either Ad Hoc mode (without anAccess Point) or Infrastructure mode (with an Access Point.) Please take a look atour Getting Started section in this manual to see examples of typical network setupsusing the DWL-G650 in both Infrastructure and Ad-Hoc modes.This manual provides a quick introduction to wireless technology and its applicationas it relates to networking. Take a moment to read through this manual and getacquainted with wireless technology.

7D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, businessor public access wireless networks. Strictly adhering to the IEEE standard, theD-Link wireless family of products will allow you to securely access the datayou want, when and where you want it. You will be able to enjoy the freedomthat wireless networking delivers.A wireless local area network (WLAN) is a cellular computer network thattransmits and receives data with radio signals instead of wires. Wireless LANsare used increasingly in both home and office environments, and public areassuch as airports, coffee shops and universities. Innovative ways to utilize WLANtechnology are helping people to work and communicate more efficiently.Increased mobility and the absence of cabling and other fixed infrastructurehave proven to be beneficial for many users.Wireless BasicsWireless users can use the same applications they use on a wired network.Wireless adapter cards used on laptop and desktop systems support the sameprotocols as Ethernet adapter cards.Under many circumstances, it may be desirable for mobile network devices tolink to a conventional Ethernet LAN in order to use servers, printers or an Internetconnection supplied through the wired LAN. A Wireless Router is a deviceused to provide this link.
8The DWL-G650 is also compatible with 802.11b wireless products, which include:2.4GHz Wireless Cardbus Adapters used with laptop computers(D-Link Air DWL-650, D-Link AirPlus DWL-650+)2.4GHz Wireless PCI cards used with desktop computers(D-Link Air DWL-520, D-Link AirPlus DWL-520+)Enhanced 2.4GHz Wireless Access Point(D-Link AirPlus DWL-900AP+)Enhanced 2.4GHz Wireless Broadband Router(D-Link AirPlus DI-614+)Wireless Basics (continued)People use wireless LAN technology for many different purposes:Mobility - Productivity increases when people have access to data in anylocation within the operating range of the WLAN. Management decisions basedon real-time information can significantly improve worker efficiency.Low Implementation Costs – WLANs (Wireless Local Area Networks) areeasy to set up, manage, change and relocate. Networks that frequently change,both physically and logically, can benefit from WLANs ease of implementation.WLANs can operate in locations where installation of wiring may be impractical.Installation Speed and Simplicity - Installing a wireless LAN system canbe fast and easy and can eliminate the need to pull cable through walls andceilings.Network Expansion - Wireless technology allows the network to gowhere wires cannot.Scalability – Wireless Local Area Networks (WLANs) can be configured in avariety of topologies to meet the needs of specific applications or existinginfrastructures. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to larger infrastructurenetworks to accommodate hundreds or thousands of users, depending on thenumber of wireless devices deployed.
9Standards-Based TechnologyThe DWL-G650 Wireless Cardbus Adapter utilizes the new 802.11g standard.The IEEE 802.11g standard is an extension of the 802.11b standard. It increasesthe 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 MPEGformat over your network without noticeable delays. This technology works bytransmitting high-speed digital data over a radio wave utilizing OFDM (OrthogonalFrequency Division Multiplexing) technology. OFDM works by splitting the radiosignal into multiple smaller sub-signals that are then transmitted simultaneouslyat different frequencies to the receiver. OFDM reduces the amount of crosstalk(interference) in signal transmissions. The D-Link DWL-G650 will automaticallysense the best possible connection speed to ensure the greatest speed andrange possible.802.11g offers the most advanced network security features available today,including: WPA, 802.1x, TKIP, AES and Pre-Shared Key mode. These securityfeatures are explained in more detail in the Introduction and the Features sectionof this manual.The DWL-G650 is backwards compatible with 802.11b devices. This meansthat if you have an existing 802.11b network, the devices in that network will becompatible with 802.11g devices at speeds up to 11Mbps in the 2.4GHz range.Also based on the IEEE 802.11b standard, the DWL-G650 is interoperable withexisting compatible 2.4GHz wireless technology with data transfer speeds ofup to 11Mbps.Wireless Basics (continued)
10Wireless Basics (continued)Installation ConsiderationsThe D-Link AirExtreme DWL-G650 lets you access your network, using awireless connection, from virtually anywhere. Keep in mind, however, that thenumber, thickness and location of walls, ceilings, or other objects that thewireless signals must pass through, may limit the range. Typical ranges varydepending on the types of materials and background RF (radio frequency)noise in your home or business. The key to maximizing wireless range is tofollow these basic guidelines:1. Keep the number of walls and ceilings between the DWL-G650 and other network devices to a minimum - each wall or ceiling can reduce your D-Link AirExtreme Wireless product’s 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! Try to make sure that devices 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 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.
