4IntroductionThe DWL-G510 has the newest, strongest, and most advanced security features availabletoday. When used with other 802.11 WPA (Wi-Fi Protected Access) and 802.1x compatibleproducts in a network with a RADIUS server, the security features include:WPA: Wi-Fi Protected Access which authorizes and identifies users based on a secretkey that changes automatically at regular intervals. WPA uses TKIP (TemporalKey Integrity Protocol) to change the temporal key every 10,000 packets (apacket is a kind of message transmitted over a network.) This ensures muchgreater security than the standard WEP security. (By contrast, the older WEPencryption required the keys to be changed manually.)802.1x: Authentication which is a first line of defense against intrusion. In theauthentication process, the Authentication Server* verifies the identity of theclient attempting to connect to the network. Unfamiliar clients would be deniedaccess.For home users that will not incorporate a RADIUS server in their network, the securityfor the DWL-G510, used in conjunction with other WPA-compatible 802.11 products, willstill be much stronger than ever before. Utilizing the Pre Shared Key mode of WPA,the DWL-G510 will obtain a new security key every time it connects to the 802.11network. You only need to input your encryption information once in the configurationmenu. No longer will you have to manually input a new WEP key frequently to ensuresecurity. With the DWL-G510, you will automatically receive a new key every time youconnect, vastly increasing the safety of your communication.* Not all servers can provide Authentication.The D-Link AirPlus Xtreme G DWL-G510 Wireless PCI Adapter is an 802.11g high-performance, wireless adapter that supports high-speed wireless networking at home,at work or in public places.Unlike most network cards, the DWL-G510 provides data transfers at up to 54 Mbps.The 802.11g standard is backwards compatible with 802.11b products.TM

6Wireless BasicsD-Link wireless products are based on industry standards to provide easy-to-use andcompatible high-speed wireless connectivity within your home, business or public accesswireless 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 networkingbrings.A Wireless Local Area Network (WLAN) is a computer network that transmits and receivesdata with radio signals instead of wires. WLANs are used increasingly in both home andoffice environments, and public areas such as airports, coffee shops and universities.Innovative ways to utilize WLAN technology are helping people to work and communicatemore efficiently. Increased mobility and the absence of cabling and other fixedinfrastructure have proven to be beneficial for many users.Wireless users can use the same applications they use on a wired network. Wirelessadapter cards used on laptop and desktop systems support the same protocols asEthernet adapter cards.People use WLAN technology for many different purposes:Mobility - Productivity increases when people have access to data in any locationwithin the operating range of the WLAN. Management decisions based on real-timeinformation can significantly improve worker efficiency.Low Implementation Costs – WLANs are easy to set up, manage, change andrelocate. 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 fastand easy and can eliminate the need to pull cable through walls and ceilings. Wirelesstechnology allows the network to go where wires cannot go - even outside the home oroffice.Scalability – WLANs can be configured in a variety of ways to meet the needs ofspecific applications and installations. Configurations are easily changed and rangefrom peer-to-peer networks suitable for a small number of users to larger infrastructurenetworks to accommodate hundreds or thousands of users, depending on the number ofwireless devices deployed.Inexpensive Solution - Wireless network devices are as competitively priced asconventional Ethernet network devices.

7Wireless Basics (continued)Standards-Based TechnologyThe DWL-G510 Wireless PCI Adapter utilizes the new 802.11g standard.The IEEE 802.11g standard is an extension of the 802.11b standard. It increases thedata 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 willbe able to transfer large files quickly or even watch a movie in MPEG format over yournetwork without noticeable delays. This technology works by transmitting high-speeddigital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing)technology. OFDM works by splitting the radio signal into multiple smaller sub-signalsthat are then transmitted simultaneously at different frequencies to the receiver. OFDMreduces the amount of crosstalk (interference) in signal transmissions. The D-Link DWL-G510 will automatically sense the best possible connection speed to ensure the greatestspeed 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 areexplained in more detail in the Introduction and the Features section of this manual.The DWL-G510 is backwards compatible with 802.11b devices. This means that if youhave an existing 802.11b network, the devices in that network will be compatible with802.11g devices at speeds up to 11Mbps in the 2.4GHz range.The DWL-G510 is compatible with 802.11g and 802.11b wireless products, which include:D-Link Air DWL-650,D-Link AirPlus DWL-650+,D-Link AirPlus Xtreme G DWL-G6502.4GHz Wireless Cardbus Adapter used with laptop computersD-Link Air DWL-520, D-Link AirPlus DWL-520+2.4GHz Wireless PCI cards used with desktop computersD-Link AirPlus DWL-900AP+, D-Link AirPlus Xtreme G DWL-2000AP2.4GHz Wireless Access PointsD-Link AirPlus DI-614+, DI-714P+2.4GHz Wireless Routers!!!!TMTM

8Installation ConsiderationsThe D-Link AirPlus Xtreme G DWL-G510 lets you access your network using awireless connection from virtually anywhere within its operating range. Keep in mind,however, that the number, thickness and location of walls, ceilings, or other objects thatthe wireless signals must pass through, may limit the range. Typical ranges vary dependingon the types of materials and background RF (radio frequency) noise in your home orbusiness. The key to maximizing wireless range is to follow these basic guidelines:Keep your product away (at least 3-6 feet or 1-2 meters) from electricaldevices or appliances that generate RF noise.4Keep the number of walls and ceilings between the DWL-G510 and other networkdevices to a minimum - each wall or ceiling can reduce your DWL-G510’srange from 3-90 feet (1-30 meters.) Position your devices so that the number ofwalls or ceilings is minimized.1Be 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. Ata 2-degree angle it looks over 42 feet (14 meters) thick! Position devices sothat the signal will travel straight through a wall or ceiling (instead of at anangle) for better reception.2Building materials can impede the wireless signal - a solid metal door or aluminumstuds may have a negative effect on range. Try to position wireless devices andcomputers with wireless adapters so that the signal passes through drywall oropen doorways and not other materials.3Wireless Basics (continued)TM

22Using the Configuration Utility (continued)Domain Name:Each server has a domain name that uniquely identifies it. That domain name is normallycontained in the Subject CN field of the server certificate. A server domain name endswith the name of a larger administrative domain, to which the server belongs.TTLS Identity:Tunneled Transport Layer Security satisfies a requirement for strong encryption andmutual authentication on Wireless networks. EAP-TTLS has a unique feature that otherprotocols do not offer. Because it sets up an encrypted tunnel for your credentials, it isalso able to pass your login name through that tunnel. That means that not only are yourcredentials secure from eavesdropping, but your identity is protected as well. Thus, withEAP-TTLS you have two identities: an inner one, and an outer one. The inner identity isyour actual user name. Your outer identity can be completely anonymous. Set yourouter identity in the TTLS Identity field.Trusted CA List:The Trusted CA List allows you to configure which authentication servers you trust forthe purpose of logging you in to the network.Click Add at the Trusted CA List at the bottom of the Advanced Security Settings page.Select the Trusted CA that you want to add and click OK.802.1x > Advanced Security Settings > Definitions of Terms (continued)Select the Trust CA:
