under Windows operating system without shutting down the system. To remove the USB adapter, gently pull the adapter out from the port. NOTE: DO NOT remove the USB adapter while transferring data (the LED is flashing). Please close the communication programs or stop the task before removing it.
Networking Application The following diagram explains the application of your USB adapter in your wireless network. To build a wireless network at home (as shown above), you may need the followings: A broadband Internet access (a Cable/DSL subscriber line) from your ISP. A proper installation of the Cable/DSL modem (consult with your Cable/DSL provider or ISP). Connect the Cable/DSL modem to your broadband router.
3 U SING T HE U TILITY Introduction Your USB adapter uses a Configuration Utility as the management software. The utility provides the user with an easy interface to change any settings related to the adapter. After you have completed the installation of the USB adapter, the Configuration Utility starts automatically as you start the computer, and the system tray icon is loaded in the toolbar (as shown below). Clicking on the utility icon will start the Configuration Utility.
Auto-Run Installation Insert the Installation CD-ROM into your computer’s CD-ROM drive to initiate the Auto-Run program, and the menu screen will appear as below. User's Guide – click to preview the User's Guide in PDF format for detailed information of the USB adapter. Install Utility – click to install the Configuration Utility. Browse CD – if you want to browse the contents of the Installation CD-ROM, click this button and the contents of the CD will be available for preview.
Installing the Configuration Utility 1. Click Install Utility from the Auto-Run menu screen. Once executed, the Setup program will extract files to launch the InstallShield Wizard; then, click Next > in the welcome screen of InstallShield Wizard. 2. Choose the destination location. If no specific requirement, leave the default setting and click Next >. 3. The InstallShield Wizard starts to install the software, and the Progress bar indicates the installation is proceeding. 4.

4. Click Advanced to bring up the Properties window. Uncheck the Use Windows to configure my wireless network settings option. Then, click OK. Uncheck this option Now, you can use the adapter’s Configuration Utility to configure your network.
Using the Configuration Utility After clicking on the Configuration Utility icon, the Link Info screen will display the settings for the adapter. Link Info Screen Status: Displays current connection state of the adapter. SSID: The Service Set Identifier is the name assigned to the wireless network. The factory SSID setting is default. Tx Rate: Tx Rate settings are automatically determined for an optimal speed up to a maximum of 54Mbps.
Link Quality: Displays the wireless signal strength for the wireless connection to the access point. Signal Strength: Displays the Link Quality for the wireless connection to the access point. The Signal Strength represents the wireless signal between the access point and the adapter. The percentage coincides with the graphical bar. Data Rate: Displays the statistics of the data that is transmitted and received.
Configuration Screen SSID: The Service Set Identifier is the name assigned to the wireless network. The factory SSID setting is set to default. Make changes here to match the SSID on the existing wireless router or access point. Wireless Mode: Infrastructure is the factory default setting. Hoc mode is used for Peer-to-Peer networking. Ad- Channel: The default channel setting is channel 6.
Preamble: Select Long or Short Preamble. The Preamble defines the length of the CRC block (Cyclic Redundancy Check is a common technique for detecting data transmission errors) for communication between the access point and the roaming wireless network adapters. Long Preamble is the default setting. High network traffic areas should use the Short Preamble. Power Mode: - Continuous Access Mode: this default setting consumes the most power. - Maximum Power Save: this setting consumes the least power.
Encryption Screen Data Encryption: Enable encryption by clicking in the box. encryption is de-selected as the default setting. Data Auth. Mode: - WEP Open Authentication: communicates the key across the network. - WEP Shared Authentication: allows communication only with other devices with identical WEP settings. - WPA: a dynamically changing encryption mechanism for wireless networking that provides the user with encryption strength up to 256-bit. - WPA-PSK: WPA authentication (802.
Key Format: ASCII or hexadecimal format. Key Length: Select the key length, either 64, 128 or 256 bits. Click Apply if you have made any changes Hexadecimal digits consist of the numbers 0-9 and the letters A-F. ASCII (American Standard Code for Information Interchange) is a code for representing English letters as numbers from 0-127.
Site Survey Screen Available Networks: The top section of the window displays the Available Networks. Scroll up and down the list and highlight the network to which you wish to connect.
