Federal Communications Commission (FCC) RF Exposure Requirements SAR compliance has been established in the laptop computer(s) configurations with PCMCIA slot on the side near the center, as tested in the application for Certification, and can be used in laptop computer(s) with substantially similar physical dimensions, construction, and electrical and RF characteristics.
1 Introduction Thank you for purchasing the 802.11g Wireless LAN PC Card. This card complies with IEEE 802.11g standard, which supports up to 54Mbps high-speed wireless network connections. It can also work with IEEE 802.11b devices. When the card connects to 11b devices, the link speed will be up to 11Mbps. For WLAN security issues, this card supports 64/128-bit WEP data encryption that protects your wireless network from eavesdropping.
2 Installation Procedure Before you proceed with the installation, please notice following descriptions. Note1: Please do not install the card into your laptop computer before installing the software program from the CD. Note2: The following installation was operated under Windows XP. (Procedures are similar for Windows 98SE/Me/2000.) Note3: If you have installed the Wireless PC Card driver &...

D. The system will automatically detect the card and display “Hardware Installation” screen. Click “Continue Anyway” to continue. E. The current setting of the “Country Channel” of the card is displayed for your reference. If you are in different country, please change the “Country Channel” from the drop-down menu and click “Next”. F.

G. The “RaConfig” utility is displayed and you can start to configure the card.
3 Configuration Utility The Configuration Utility is a powerful application that helps you configure the PC card and monitor the link status and the statistics during the communication process. The Configuration Utility appears as an icon on the system tray of Windows while the card is running. You can open it by double-click on the icon.
Parameter Available Networks Rescan Button Connect Button Add to Profile Button Profile The “Profiles List” is for you to manage the networks you connect to frequently. You are able to Add/Delete/Edit/Activate a profile. Parameter Profiles List Add/Delete/Edit Button Activate Button Description This list shows all available wireless networks within range of your card.
3.2.1 Configure the Profile System Configuration Parameter Profile Name SSID Power Saving Mode Description Define a recognizable profile name for you to identify the different networks. The SSID (up to 32 printable ASCII characters) is the unique name identified in a WLAN. The ID prevents the unintentional merging of two co-located WLANs.

Parameter Network Type Transmit Power 11B Preamble Type RTS Threshold Fragment Threshold Channel Description Infrastructure – This operation mode requires the presence of an 802.11 Access Point. All communication is done via the Access Point or Router. Ad-Hoc – Select this mode if you want to connect to another wireless stations in the Wireless LAN network without through an Access Point or Router.

Authentication vs. Security Parameter Authentication Type Description This setting has to be consistent with the wireless networks that the card intends to connect. None – No authentication is needed among the wireless network. Shared – Only wireless stations using a shared key (WEP Key identified) are allowed to connecting each other.
Page 16
Parameter Encryption Mode WPA Pre-Shared Key WEP Key (Key1 ~ Key4) Description None – Disable the WEP Data Encryption. WEP – Enable the WEP Data Encryption. When the item is selected, you have to continue setting the WEP Encryption keys. TKIP –...
3.2.2 Enable WPA in Windows XP Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security enhancement that strongly increases the level of data protection (encryption) and access control (authentication) for existing and future wireless LAN systems. The technical components of WPA include Temporal Key Integrity Protocol (TKIP) for dynamic key exchange, and 802.1x for authentication.

3. Press “Configure” button to configure the WPA function for the current network. Note: Uncheck “Use Windows to Configure my wireless network settings”, the “RaConfig” utility will be enabled again. Parameter Network Authentication Description Open –No authentication is needed among the wireless network. Shared –...
Parameter Data Encryption Link Status From the “Link Status” option, you can view all the information of the network you are connecting to. Parameter Status Current Channel Description WEP – In WPA or WPA-PSK mode, WEP is also able to be the encryption method for the transmission data.
Parameter Current Tx Rate Throughput (Kbits/sec) Link Quality Signal Strength Statistics This option enables you to view the available statistic information with its Tx counts (Tx success, Tx error, RTS Success and RTS Failed), and its Rx counts (Rx success, Rx error). You may reset the counters by clicking ”Reset Counter”.
Advance This option enables you to configure more advanced settings, for example: wireless mode, protection mode and etc. Parameter Wireless Mode Tx BURST B/G Protection Description 802.11 B/G mix – If you have a mix of 802.11b and 802.11g wireless stations in your network, it is recommended to setting the card to this mode.
Parameter ADHOC_OFDM Tx Rate Turn Off RF Button About By choosing this option, you can click the hyperlink to connect the website for the information of the wireless chipset vendor and review basic information about the Utility such as the Driver, Utility and EEPROM Version.
4 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the adapter. 1. What is the IEEE 802.11g standard? 802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream wireless LAN technology for the home, office and public networks.

6. What is BSS ID? A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. 7. What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard.

13. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communication systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade off 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.
