WIRELESS USB ADAPTER WN3501AR Wireless USB Adapter WN3501AR is an 11 Mbps wireless network adapter that seamlessly integrates with existing Ethernet networks to support applications such as mobile users or temporary conferences. This solution offers fast, reliable wireless connectivity with considerable cost savings over wired LANs (which include long-term maintenance overhead for cabling). Just plug wireless cards into your desktop PCs and start networking.
HARDWARE DESCRIPTION Wireless USB Adapter WN3501AR supports an 11 Mbps half-duplex connection to Ethernet networks. This adapter is fully compliant with 2.4 GHz DSSS CSMA/CA wireless networking as defined in IEEE 802.11b. It can be installed in any notebook or desktop with a USB port. Support is provided for Windows 98/Me/2000.
Temporary LANs for special projects or peak time Trade shows, exhibitions and construction sites which need a temporary setup for a short time period. Retailers, airline and shipping companies who need additional workstations for a peak period.
LED Indicators The Wireless USB Adapter WN3501AR includes three LED indicators, as described in the following figure and table. System Requirements Before you install the Wireless USB Adapter WN3501AR, check your system for the following requirements: 4 An available USB port in your computer. Windows 98/Me/2000 (Have the Windows installation CD-ROM ready for use during installation). A minimum of 1 MB of free disk space for installing the driver and utility program. Another IEEE 802.
INSTALLATION WARNINGS: Backup your driver diskette and use the copy as the working diskette to protect the original from accidental damage. 1. Select an unused USB port and remove its protective bracket. 2. Carefully insert the USB cable and press until it is firmly seated in the USB port. 3. Install the appropriate network driver for your operating system. Drivers can be found on the driver diskette. See Driver Installation for more information. 4.
DRIVER INSTALLATION The diskette labeled Driver Diskette, that comes with the package contains all the software drivers available for the Wireless USB adapter WN3501AR. Select the driver you need for your system and refer to this guide for the installation and configuration procedure. WINDOWS 98/ME INSTALLATION 1. Windows 98/Me will automatically detect the new hardware and prompt you to install the driver. Click Next to find the driver. 2.
3. Click Next to copy files from the floppy disk. 4. Set the Channel to the same radio channel as that used by the other wireless clients in your group. However, if you are connecting to a network via an access point, the adapter will automatically set the channel to be the same as that used by the Access Point.
5. For more secure data transmission, set the Encryption to 128-bit or 64-bit to ensure wireless network security. The advance Wired Equivalent Privacy (WEP) is implemented in this card to prevent unauthorized access. The 128-bit setting gives a higher level of security but the setting must be the same for all clients in your wireless network. (Default: Disabled) To completely configure WEP, you must use the Configuration Utility.
7. Set the Operating Mode to 802.11 Ad-Hoc or Infrastructure depending on the type of network you want to connect to. 8. Set the RTS Threshold to the same as that used by other devices in your network.
9. Set the SSID identifier to the same as that used by the ad hoc work group or access point you want to connect to. If you will be roaming among multiple Access Points with different BSSIDs, a value of ANY will allow connection to any SSID. 10. Insert Windows98/Me CD-ROM and click OK. Windows will copy source file to your system.
11. If you want to add more protocols after installation, go to control panel and double-click Network. 12. Select the Configuration tab and click Add to install the network protocols you want to use, such as IPX/SPX, NetBEUI or TCP/IP. If you install TCP/IP, be sure to set the appropriate Gateway, DNS Server, and Domain for your network. If you install an IPX/SPX compatible protocol, then you also need to install the Client for NetWare Networks. 13. Click File and Print Sharing printers.
WINDOWS 2000 INSTALLATION 1. Windows 2000 will automatically detect the new hardware and prompt you to install the driver Click Next to find the driver. 2. Insert the floppy disk labeled Driver/Utility diskette choose Floppy disk drivesand click Next.
3. Click Next to copy files from the floppy disk. 4. Finish the driver installation.
5. If you want to add more protocols after installation, go to control panel and double click on Network and Dial-up Connections and double click Local Area Connection X, click Properties. 6. Select the General tab and click install to install the network protocols you want to use, such as IPX/SPX, NetBEUI or TCP/IP. If you install TCP/IP, be sure to set the appropriate Gateway, DNS Server, and Domain for your network.
CONFIGURATION AND DIAGNOSTIC UTILITY Wireless USB Adapter WN3501AR provides free optional management software for quick network configuration and easy diagnostics. The Driver/ Utility diskette that comes with the package contains a user-friendly interface for configuring the Wireless USB Adapter WN3501AR. Utility Installation To install the utility software: 1. Insert the Driver/Utility diskette in your PCs floppy drive (A:). 2. Select run... from Windows Start menu bar. 3. Enter A:\Utility\Setup
Quick-Launch Icon After the utility program is running, it will have a Quick Launch icon in the lower right hand corner of the task bar. Double clicking the icon in the Quick Launch bar will open the USB Utility program, providing quick access to all settings of the adapter. This configuration software includes the following functions: Monitor - Allow you to monitor network status and configure parameters for the wireless adapter. Statistics - Show the statistics of the wireless adapter.
Monitor Screen When you start the wireless USB utility, the information window for the WN3501AR is shown as the figure below. Click on the Monitor tab to monitor the network status of the wireless adapter, including the BSS ID, current channel, link quality, and signal strength. Click Modify to configure Operating Mode, Channel, SSID and Tx Rate. After configuration, just click Apply to save the changes. Operating Mode - Set the station operation mode to 802.
Tx Rate - Indicates the communication rates. Select appropriate transmission speed to match your wireless LAN settings. (Default: Fully Automatic) Note : The Channel can only be set when the Operating Mode is 802.11 Ad-Hoc.
Statistics Screen The Statistics screen displays Data Frames and Management Frames. (Please see Terminology section for Data Frames and Management Frames definitions) Site Survey Screen The Site Survey screen displays all APs in wireless LAN, and you can choose one of them to connect to by double clicking.
Encryption Screen Encryption - For more secure data transmission, set the Encryption to 128-bit or 64-bit to ensure wireless network security. Wired Equivalent Privacy (WEP) is implemented in this adapter to prevent unauthorized access to your wireless network.

NETWORK CONFIGURATION AND PLANNING WN3501AR Wireless Solution supports a stand-alone wireless network configuration, as well as an integrated configuration with 10 Mbps Ethernet LANs. The WN3501AR USB adapter can be configured as: Ad hoc for departmental or SOHO LANs Infrastructure for enterprise LANs Network Topologies Ad hoc Wireless LAN An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN.
Infrastructure Wireless LAN The WN3501AR can also provide access to a wired LAN for wireless workstations. An integrated wired and wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN.
Setting the Communication Domain Stationary Wireless PCs The Basic Service Set (BSS) is the communication domain for each access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the wireless card to the BSS ID of the access point you want to connect to. Check with your administrator for the BSS ID of the access point he wants you to connect to. Roaming Wireless PCs A wireless infrastructure can also support roaming for mobile workers.
