LINK Wireless Basics Wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home or business. Strictly adhering to IEEE 802.11b, our wireless family of products will allow you to access the data you want, when and where you want it. No longer will you be limited to one location or forced to run new wiring through your home or office. You will be able to enjoy the freedom that wireless networking delivers. A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and office environments. 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 has proven to be beneficial for many users. Wireless users can use the same network applications they use on an Ethernet LAN. Wireless adapter cards used on laptop and desktop systems, support the same protocols as Ethernet adapter cards. For most users, there is no noticeable functional difference between a wired Ethernet desktop computer and a wireless computer equipped with a wireless adapter other than the added benefit of the ability to roam within the wireless-cell. Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Access Point (AP) is a device used to provide this link. People use wireless LAN technology for many different purposes. Mobility - Productivity increases when people have access to data in any location within the operating range of the WLAN. Ad-hoc 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, both physically and logically, can benefit from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impractical. Furthermore, IEEE standardization mandates interoperability of all WLAN devices that conform to the 802.11b set of standards. Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Wireless Basics (continued) Installation Flexibility - Wireless technology allows the network to go where wires cannot go. Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware might be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs will be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves, adds, and changes. Scalability - Wireless LAN systems can be configured in a variety of topologies 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 full infrastructure networks of thousands of users that allow roaming over a broad area. Standards-based Technology Based on the IEEE 802.11b standard, the WUS-B12 is also interoperable with existing compatible 2.4 GHz wireless technologies, with data transfer speeds of up to 11 Mbps. Installation Considerations The WUS-B12 lets you access your network with your laptop computer from virtually anywhere you want. Keep in mind, however, that the number and thickness of walls, ceilings or other objects that the wireless signals must pass thru may limit range. Typical ranges vary depending on the types of materials and background RF noise in your home or business. The key to maximizing range is to follow these basic principles:

6 Wireless Basics (continued) 1. Keep the number of walls and ceilings between the Access Point and your receiving device to a minimum each wall or ceiling can reduce your wireless products range from 3-90 feet (1-30 meters.) For some businesses or for a large residential home deployment, it may be beneficial to have more than one access point with overlapping coverage. 2. Be aware of the direct line between Access Points and computers with wireless adapters - 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 the Access Points and Adapters 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 Access Points, and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. 4. Make sure that the antenna is positioned for best reception by using the software signal strength tools included with your product. 5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme RF noise. For the average residence, range should not be a problem. If you experience low or no signal strength in areas of your home that you wish to access, consider positioning the Access Point in a location directly between the computers with wireless adapters that will be connected. Additional Access Points can be connected to provide better coverage in rooms where the signal does not appear as strongly as desired. Using radio frequency (RF) technology, WLANs (Wireless Local Area Networks) transmit and receive data over the air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs. Getting Started To begin, select the type of wireless network you will be building. We will discuss the following types of networks in this section:

Look under Device Status to check that the device is working properly. WUS-B12 Wireless USB Adapter Click OK Troubleshooting (continued) 2. The computer does not recognize the WUS-B12 802.11b Wireless USB Adapter. Make sure that the WUS-B12 Wireless USB Adapter is properly seated in the computers USB port. If Windows does not detect the hardware upon insertion of the adapter, make sure to completely remove drivers that were previously installed. To remove the drivers, do the following:

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 the files NetA3AB.inf and A3AB.sys. 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 certification into oem.inf files (e.g., oem1.inf.) 3. The WUS-B12 802.11b Wireless USB Adapter does not work properly after the driver is installed. Restart the computer. (In some cases, it will be necessary to restart the computer after installing the drivers.) 60 In Windows XP, go to Start>Control Panel>System>Hardware Tab> click on the Device Manager Tab> click on Network Adapters> double click on D-Link AirPro WUS-B12 Wireless USB Adapter>

make sure that This device is working properly is displayed under Device Status under the General Tab. (Please refer to Checking the Installation of the Drivers for the Wireless Adapter in the Networking Basics section of this manual for more information.) If the device is not working properly and a yellow exclamation mark is displayed, then there is probably a resource conflict. In this case, make sure the computer system has a free IRQ and if necessary, uninstall the drivers, restart the system, and repeat the driver installation procedure. Troubleshooting (continued) 4. The wireless client cannot access the Internet in the Infrastructure mode. Make sure the wireless client is associated and joined with the correct Access Point. To check this connection: Right-click on the Networking Icon in the taskbar> select View Available Wireless Networks. The Connect to Wireless Network screen will appear. Please make sure you have selected the correct available network, as shown in the illustrations below. Check that the IP Address assigned to the wireless adapter is within the same IP Address range as the access point and gateway. (For example: if one computer has an IP Address of 192.168.0.2, the other computers should have IP Addresses that are sequential, like 192.168.0.3 and 192.168.0.4. The subnet mask must be the same for all the computers on the network.) To check the IP Address assigned to the wireless adapter, double-click on the Network Connection Icon in the taskbar > select the Support tab and the IP Address will be displayed. (Please refer to Checking the IP Address in the Networking Basics section of this manual.) If it is necessary to assign a Static IP Address to the wireless adapter, please refer to the appropriate section in Networking Basics. If you are entering a DNS Server Address, you must also enter the Default Gateway Address. (Remember that if you have a DHCP-capable router, you will not need to assign a Static IP Address. See Networking Basics: Assigning a Static IP Address.)
