IntroductionThe GL2422MU-MT 2.4GHz Wireless USB Adapter is a convenientPlug & Play USB 1.1 solution that brings wireless networking to your laptop ordesktop PC. It provides up to 256-bit level of WEP security to your wirelessdata transfers. After completing the steps outlined in the Quick Installation Guide (included inyour package) you will have the ability to share information and resources,such as files, printers, and Internet connection and enjoy the freedomthat wireless networking delivers.The GL2422MU-MT comes with software drivers for the most popular MicrosoftWindows operating systems and can be integrated into a larger network, runningWindows XP, Windows 2000, Windows Me, or Windows 98SE in either Ad-Hoc mode (without an Access Point or Router) or Infrastructure mode (with anAccess Point or Router). The IEEE 802.11b Ethernet standard allows you toconnect computers and 802.11b compatible devices at speeds up to 22Mbps*,dependent upon the distance between wireless adapters, the configuration ofyour working environment, or the capabilities or limitations of your computersystems.* This is the theoretical maximum of the chipset used in the GL2422MU-MT USB Adapter. Actual through-put may vary.

You will be able toenjoy the freedom that wireless networking brings.A WLAN is a cellular computer network that transmits and receives data withradio signals instead of wires. WLANs are used increasingly in both home andoffice environments, and public areas such as airports, coffee shopsand universities. Innovative ways to utilize WLAN technology are helping people towork and communicate more efficiently. Increased mobility and the absence ofcabling and other fixed infrastructure have proven to be beneficial for manyusers.Wireless 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.

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 befast 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 - evenoutside the home or office.Scalability . WLANs can be configured in a variety of topologies to meet theneeds of specific applications and installations. Configurations are easilychanged and range from peer-to-peer networks suitable for a small number ofusers to larger infrastructure networks to accommodate hundreds or thousandsof users, depending on the number of wireless devices deployed.Inexpensive Solution - Wireless network devices are as competitivelypriced as conventional Ethernet network devices.Standards-Based TechnologyBased on the IEEE 802.11b standard, the GL2422MU-MT is interoperable withexisting compatible 2.4GHz wireless technology with data transfer speeds ofup to 22Mbps when used with other devices.
Wireless Basics (continued)Installation ConsiderationsThe GL2422MU-MT lets you access your network, using a wirelessconnection, from virtually anywhere within its operating range. Keep in mind,however, that the number, thickness and location of walls, ceilings, or otherobjects that the wireless signals must pass through, may limit the range. Typicalranges vary depending on the types of materials and background RF (radiofrequency) noise in your home or business. The key to maximizing wirelessrange is to follow these basic guidelines: Keep the antenna of the GL2422MU-MT in an upright position.Keep the number of walls and ceilings between the GL2422MU-MT and othernetwork devices to a minimum - each wall or ceiling can reduce your D-Link wireless product.s range from 3-90 feet (1-30 meters.) Position yourdevices so that the number of walls or ceilings is minimized.Be aware of the direct line between network devices. A wall that is 1.5 feetthick (.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! Positiondevices so that the signal will travel straight through a wall or ceiling (insteadof at an angle) for better reception.Keep your product away (at least 3-6 feet or 1-2 meters) from electricaldevices or appliances that generate extreme RF noise.Building Materials can impede the wireless signal - a solid metal door oraluminum studs may have a negative effect on range. Try to position wirelessdevices and computers with wireless adapters so that the signal passesthrough drywall or open doorways and not other materials.
Getting Started With its default settings, the GL2422MU-MT will connect with other products, right out of the box.A wireless broadband Router- GL2422RTA laptop computer with a USB wireless network adapter - GL2422MU-MTA desktop computer with a USB wireless network adapter - GL2422MU-MTA Cable modem - There are basically two modes of networking:Infrastructure . using an Access Point or Router, such as the DI-614+.Ad-Hoc . directly connecting to another computer, for peer-to-peercommunication, using wireless network adapters on each computer, suchas two or more GL2422MU-MT wireless USB adapters.On the following pages we will show you an example of an InfrastructureNetwork and an Ad-Hoc Network.An Infrastructure network contains an Access Point or Router. TheInfrastructure Network example shown on the following page contains thefollowing network devices (your existing network may be comprisedof other devices):You will need broadband Internet access (a Cable or DSL-subscriber line intoyour home or office)Consult with your Cable or DSL provider for proper installation of the modemConnect the Cable or DSL modem to your broadband router (see the QuickInstallation Guide included with your router.)Install the DWL-120 wireless USB adapter into an available USBport on your desktop computer. (See the Quick Installation Guide included withthe GL2422MU-MT.)If you are connecting a laptop computer to your network, you can install theGL2422MU-MT into an available USB port on your laptop.
Using the Configuration Utility GL2422MU-MT uses the Configuration Utility as the managementsoftware. The utility provides the user an easy interface to change any settingsrelated to the wireless adapter. When the computer is started, theConfiguration Utility starts automatically and the system tray icon is loadedin the toolbar (see illustration below.) Clicking on the utility icon will start theConfiguration Utility. Another way to start the Configuration Utility is toclick on Start>Programs> GL2422MU-MT.If you are using Windows XP, you can use either the Zero Configuration Utilityor the Configuration Utility. To use the Configuration Utility withXP, click on the Zero Configuration Utility in the taskbar in the lower corner ofyour computer screen and uncheck the box in the properties windowthatenables windows configuration. After you have done this, you can then use the Configuration Utility with XP.Link InfoSSID:The Service Set Identifier is the name assigned to the wireless network.

Why can.t I get a wireless connection?If you have enabled Encryption on the GL2422MU-MT, you must also enable en-cryption on all wireless devices in the network in order to establish a wirelessconnection.Antenna Orientation- Try different antenna orientations for theGL2422MU-MT. Try to keep the antenna at least 6 inches away from thewall or other objects.If you are using 2.4GHz cordless phones, X-10 equipment or other homesecurity systems, ceiling fans, and lights, your wireless connection willdegrade dramatically or drop altogether. Try changing the Channel onyour Router, Access Point and Wireless adapter to a different Channelto avoid interference.Keep your product away (at least 3-6 feet) from electrical devices thatgenerate RF noise, like microwaves, Monitors, electric motors, etc.The Encryption settings are: 64, 128 or 256-bit. Make sure that the en-cryption bit level is the same on the Router and the GL2422MU-MT.Make sure that the SSID on the Router (if you have one in your network)and the GL2422MU-MT are exactly the same. If they are not, wireless con-nection will not be established.
