4IntroductionThe D-Link AirPlus Xtreme G WUA-2340 Wireless G USB Adapter is an802.11b/802.11g high-performance,convenient Plug & Play USB 2.0 solutionthat brings wireless networking to your laptop or desktop PC.With a maximum wireless signal rate of up to 54Mbps (108Mbps* in Turbomode) you can connect to a wireless network at home, at the office or at anywireless hotspot. Now you can stay connected wherever you are andwherever you go.The WUA-2340 is Wi-Fi compliant, meaning that it can connect and interoperatewith other 802.11b or 802.11g Wi-Fi-compliant wireless routers, access pointsand adapters. The WUA-2340 connects to any available USB port on a laptop ordesktop Windows -based computer and also includes a USB cradle. With theoptional USB cradle, the WUA-2340 can be positioned virtually anywhere at aworkstation to achieve the best available wireless signal reception - whetherthat workstation is in your office, on your deck or patio, by the pool, at the localcoffee shop, or in an airport terminal while waiting to board your next flight.The adapter works with Microsoft Windows XP and Windows 2000 operatingsystems to ensure that you’ll be up and running on a wireless network in just amatter of seconds.Using its default settings, the WUA-2340 automatically connects to otherD-Link AirPlus Xtreme GTM wireless products as soon as it active.TM*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput will vary. Network conditions and evironmental factors lower actual data throughput rate.The WUA-2340 has the newest, strongest and most advanced security featuresavailable today. When used with other 802.11 WPA (Wi-Fi Protected Access)and 802.1x compatible products in a network with a RADIUS server, the securityfeatures include:WPA: Wi-Fi Protected Access which authorizes and identifies users basedon a secret key that changes automatically at regular intervals. WPAuses TKIP (Temporal Key Integrity Protocol) to change the temporalkey every 10,000 packets (a packet is a kind of message transmittedover a network.) This ensures much greater security than the standardWEP security. (By contrast, the previous WEP encryptionimplementations required the keys to be changed manually.)

5For home users that will not incorporate a RADIUS server in their network, thesecurity for the WUA-2340, used in conjunction with other WPA-compatible802.11 products, will still be much stronger than ever before. Utilizing thePre-Shared Key mode of WPA, the WUA-2340 will obtain a new security keyevery time it connects to the 802.11 network. You only need to input yourencryption information once in the configuration menu. No longer will you haveto manually input a new WEP key frequently to ensure security. With theWUA-2340 , you will automatically receive a new key every time you connect,vastly increasing the safety of your communication.Introduction (continued)802.1x: Authentication which is a first line of defense against intrusion. In theauthentication process, the Authentication Server verifies the identity ofthe client attempting to connect to the network. Unfamiliar clients wouldbe denied access.

7Wireless 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.D-Link wireless products are based on industry standards to provideeasy-to-use and compatible high-speed wireless connectivity within your home,business or public access wireless networks. D-Link wireless products willallow you access to the data you want, when and where you want it. You will beable to enjoy the freedom that wireless networking brings.A wireless local area network (WLAN) is a computer network that transmitsand receives data with radio signals instead of wires. WLANs are usedincreasingly in both home and office environments, and public areas such asairports, 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 to many users.People use WLAN 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 are easy to set up, manage, changeand relocate. Networks that frequently change can benefit from WLANs easeof implementation. WLANs can operate in locations where installation of wiringmay 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.Wireless technology allows the network to go where wires cannot go - evenoutside the home or office.Inexpensive Solution - Wireless network devices are as competitively pricedas conventional Ethernet network devices.Scalability - WLANs can be configured in a variety of ways to meet the needsof specific applications and installations. Configurations are easily changedand range from Peer-to-Peer networks suitable for a small number of users tolarger Infrastructure networks to accommodate hundreds or thousands ofusers, depending on the number of wireless devices deployed.

8Installation ConsiderationsThe WUA-2340 lets you access your network using a wireless connection fromvirtually anywhere within its operating range. 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) noisein your home or business. The key to maximizing wireless range is to followthese 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 WUA-2340 and othernetwork devices to a minimum - each wall or ceiling can reduce yourWUA-2340 range from 3-90 feet (1-30 meters.) Position your devicesso that the number of walls or ceilings is minimized.1Be aware of the direct line between network devices. A wall that is 1.5feet 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 awall or ceiling (instead of at an angle) for better reception.2Building materials can impede the wireless signal - a solid metal dooror aluminum studs may have a negative effect on range. Try to positionwireless devices and computers with wireless adapters so that thesignal passes through drywall or open doorways and not other materials.3Wireless Basics (continued)

FTP is most commonly used to upload anddownload files on the Internet.Gopher: Gopher is an early Internet protocol that organizes files in astructured list for database searching.Secure: HTTPS protocol is based on SSL (Secure Sockets Layer) technology.It is a protocol for transmitting private documents over the Internet using aprivate key to encrypt data. URLs that begin with HTTPS often use the protocolto securely obtain confidential information such as credit card numbers.Socks: Socks is a proxy server that provides a simple firewall. SocksV5 offersauthentication.Exceptions: To allow specific IP addresses to bypass proxy servers, enter theIP addresses here. You can also enter “wildcards” to allow a category of websiteto bypass the proxy servers. For instance, if you enter www.*.com, the browserwill bypass the proxy servers for most Websites.
