2 Installation Procedure 2.1 Windows 98SE/Me/2000 Before you proceed with the installation, please notice following descriptions. Note1: The following installation was operated under Window s 2000. (Procedures will be the same for Windows 98SE/Me.) Note2: If you have installed the Wireless USB Adapter driver & utility before, please uninstall the old version first. 2.1.1 Install the Driver 1.
4. After completing the Utility installation, please execute “ZDConfig” program (click “Start” button and select “ZyDAS Wireless LAN – USB”) to start using the WLAN USB Adapter. 2.2 Windows XP The installation process in Windows XP is similar with the process in windows 98SE/Me/2000. Please refer to the instructions described in section 2.1. Due to the Windows XP has built-in wireless network utility you may decide to use the system’s utility or the one provided by this USB adapter.
3. Execute “ZDConfig” program (click “Start” button and select “ZyDAS Wireless LAN – USB”). Note: If you don’t disable the XP’s Utility, you can only see the link status during communication process from the USB Adapter’s utility.
3 Configuration Utility The Configuration Utility is a powerful application that helps you configure the Wireless LAN Mini USB Adapter and monitor the link status during the communication process. This utility can be used to change the following configuration parameters when the device is active. 3.
Parameter Description More Setting button Press this button for more settings including disable/enable WEP and Power Saving Mode. Please refer to Section 3.2, 3.3 and 3.4. Link Status Display the status of the wireless connection. Signal Strength This bar shows the signal strength level. The higher percentage shown in the bar, the more radio signal been received by the adapter. This indicator helps to find the proper position of the wireless device for quality network operation.
Parameter General Connection Setting Channel Description Select the number of the radio channel used for the networking. The channel setting of the wireless stations within a network should be the same. TxRate Select the basic transmit rate to be used: 11, 5.5, 2 or 1Mbps. If “Auto“ is selected, the adapter will automatically adjust to the highest possible rate according to the interference or obstacles. SSID The SSID (up to 32 printable ASCII characters) is the unique name identified in a WLAN.
Parameter Description Load factory default setting To restore to factory default, please press this button. The default values are as follows. Channel: 6 TxRate: Auto SSID: Any Network Type: Infrastructure Advanced Setting... button For more advanced setting, please press this button. To know more of the setting, please refer to Section 3.4. Information button To view the version of the driver, firmware and the MAC Address of the adapter, press the button. Other 3.
Parameter Description Authentication Mode This setting has to be consistent with the wireless stations which the adapter intends to connect. • Open System – No authentication is needed among the wireless stations. • • Shared Key – Only wirelss stations using a shared key (WEP Key identified) are allowed to connecting each other. Setup the same key as the wireless stations which the adapter intends to connect.
3.4 Advanced Setting The “ Advanced Setting” allows user to enable/disable power saving mode, setup the fragmentation threshold and RTS/CTS threshold of the adapter. Parameter Power Saving Mode Enable auto power saving Description Check the check box to enable power saving mode. You may control the power consumption of the adapter by adjusting the save power level from 1 to 4. The higher power save level selected, the lower power used.
4 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the adapter. 1. What is the IEEE 802.11b standard？ The IEEE 802.11b Wireless LAN standard subcommittee which formulat es the standard for the industry. The objective is to enable wireless LAN hardware from different manufactures to communicate. 2. What does IEEE 802.11 feature support ？ The product supports the following IEEE 802.
9. What is DSSS？ What is FHSS？ And what are their differences？ Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-sequence spreadspectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted.
