Chapter 1 Introduction Thank you for purchasing WL-U350 USB Wireless LAN Adaptor. This device is an IEEE 802.11b Wireless USB Adapter. It can operate in either Ad-Hoc mode (Point to Point/Point to Multipoint without Access Point) or Infrastructure mode (Point to Point/Point to Multipoint with Access Point). It operates in 2.4GHz unlicensed ISM band in the home or office environment. WL-U350 provided with a built-in dipole antenna and is connected to computer through 1 meter USB cable.
Point is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled. The use of a unique ID in a BSS is essential. All WL-U350 equipped PCs configured without roaming options in an independent BSS must be configured with a BSS ID corresponding to the WL-U350 used in the BSS. Check your WL-U350 for its BSS ID or use the Site Survey function on Configuration Utility program to determine the BSS ID.
WL-U350 offers a fast, reliable, cost-effective solution for wireless client access to the network in applications like these: 1. Remote access to corporate network information E-mail, file transfer and terminal emulation. 2. Difficult-to-wire environments Historical or old buildings, asbestos installations, and open area where wiring is difficult to employ. 3. Frequently changing environments Retailers, manufacturers and banks who frequently rearrange the workplace and change location. 4.
Power Consumption TX: 5V, 460mA RX:5V, 260mA Stand by / sleep mode: 5V, 20mA Dimension (mm) 95 x 65 x 12.
Chapter 2 Installation Procedure Before you proceed with the installation, it is necessary that you have enough information about the Wireless USB Adapter. Note that the provided Configuration utility is for Windows 98/Me/2000 only. The installation of the utility will also install the driver. Thus, it is not necessary to install driver separately on Windows 98/Me/2000. Windows XP already has provided an interface to configure our WL-U350. Thus, you should only install the driver for Windows XP. 2.
D. Click “Next” to check if any installed utility and proceed to next step. If you have installed the utility, uninstall the utility before click “Next”. E. To install to this folder in program files, click “Next” .To install to a different folder click “ Browse“ and select another folder .Then click “Next“ . F. You can change the Program Folder name as you wish or use the default name to continue. Click “Next” to continue.
G. In the following Wizard box, You have to select the operating mode to “Ad-Hoc” or “Infrastructure”, then click “Next”. 1. Ad Hoc mode: In this mode you will be asked to set ESSID and the Channel as desired. Then click “Next” to complete the setting. 2. Infrastructure: In this mode you will be asked to specify the ESSID only and click “Next” to complete the setting.
H. I. Click “Next“ to begin copying file to your hard disk or click “Back” to reconfigure. After Windows 2000 finishes copying the files, Use bundled USB cable to connect WL-U350 to your PC or Notebook’s USB port. J. Windows will automatically detect WL-U350. For a while, this dialog box will appear. Please click “Yes’ to continue the driver installation. K. After the driver installation, the completing window appears. Please click “Finish” and restart the computer.
L. After restarting the computer, the Configuration & Monitor Utility icon will be shown on system tray, If not, that mean the installation is fail. Please uninstall the driver from the system then repeat the installation process. Now, the Wireless LAN USB adaptor is SUCCESSFULLY installed. 2.2 Windows XP Installation Windows XP have provided a interface to configure our WL-U350. Thus, you should only install the driver for Windows XP. A.
C. The Hardware Installation box will appear, click “Continue Anyway” to start driver installation. D. Click “Finish” to complete the driver installation. E. After complete the driver installation, you can now use Windows XP’s built-in utility to configure the WL-U350. Please click the “Start” button and choose “Connect To”. Select the “Wireless Network Connection” and the “Connect to Wireless Network” dialog box will appear.
Chapter 3 Configuration Utility The Configuration Utility is a powerful application that helps you to configure the Wireless USB Adapter and monitor the statistics of the communication process. By Double Click the icon on the system tray will brings you to the configuration mode. This utility can be used to change the following configuration parameters when the device is active. Note: Click the “Exit” button will exit the configuration application. 3.
communication is done from client to client without the use of an Access Point. Channel: Shows the number of the radio channel used for the networking. Only Access Points and Ad-Hoc nodes create the BSSID. This parameter is not active in the infrastructure operation mode. SSID: Shows the SSID of the BSS that one willing to join. Tx Rate: Shows the Data Transfer Rate. There are 1 Mbps, 2M bps, 5.5 Mbps, 11 Mbps, and auto mode.
3.3 "Site Survey" This screen shows all the AP or Adaptor nearby when operating in Ad-Hoc mode. Click “Re-Scan“ to collect the BSSID and Channel information of all the wireless devices near by. If one wishes to connect to any device on the list, double-click the selected list and the adapter will connect to the selected device automatically. 3.4 "Encryption Additional security can be achieved by using the WEP (Wired Equivalent Privacy) encryption.
3.5 "Advanced There are Preamble Type, Fragmentation Threshold, and RTS/CTS Threshold settings under this mode. Preamble Type (Short/Long): Preamble is the first subfield of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput performance. Fragmentation threshold: The size at which packets will be fragmented. Choose a setting within a range of 256 to 2346 bytes.
Chapter 4 Troubleshooting This section provides solutions to problems usually encountered during the installation and operation of this Wireless USB Adaptor. Read the description below to solve your problems. What is the IEEE 802.11b standard? The IEEE 802.11b Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufactures to communicate. What IEEE 802.
produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread –spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
