  • Page 6: Introduction

    1 Introduction Thank you for purchasing the 802.11g Wireless LAN PCI 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.

  • Page 7: Package Contents

    • Security: 64/128-bit WEP Data Encryption, WPA, AES and IEEE 802.1x • Antenna: External detachable dipole antenna (Connector: RP-SMA connector, Cable Length: 94 cm) • Drivers: Windows 98SE/Me/2000/XP • LEDs: TX/RX, Link • Transmit Power: 16dBm~18dBm • Power consumption: Tx: 350mA, Rx: 250mA •...

  • Page 8: Installation Procedure

    2 Installation Procedure Before you proceed with the installation, please notice following descriptions. Note1: The following installation was operated under Windows XP. (Procedures are similar for Windows 98SE/Me/2000.) Note2: If you have installed the Wireless PCI Card driver & utility before, please uninstall the old version first.
  • Page 9 C. Click “Easy Install” or “Next” to continue. D. The system starts to install the software of the card. Please wait a moment. 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”...
  • Page 10 F. Click “Finish” to complete the installation. G. The “RaConfig” is displayed and you can start to configure the card.

  • Page 11: Configuration Utility

    3 Configuration Utility The Configuration Utility is a powerful application that helps you configure the PCI 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.

  • Page 12: Profile

    Parameter Description Available Networks This list shows all available wireless networks within range of your card. It also displays the information of the networks including the SSID, BSSID, Signal Strength, Channel, Encryption, Authentication and Network Type. If you want to connect to any networks on the list, double-click the item on the list, and the card will automatically connect to the selected network.

  • Page 13: Configure The Profile

    3.2.1 Configure the Profile System Configuration Parameter Description Profile Name Define a recognizable profile name for you to identify the different networks. SSID 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.
  • Page 14 Parameter Description Network Type 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.
  • Page 15 Authentication vs. Security Parameter Description Authentication Type 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 Description Encryption Mode 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 – TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This insures much greater security than the standard WEP security.

  • Page 17: Enable Wpa In Windows Xp

    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.
  • Page 18 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 Description Network Authentication Open –No authentication is needed among the wireless network. Shared –...

  • Page 19: Link Status

    Parameter Description Data Encryption WEP – In WPA or WPA-PSK mode, WEP is also able to be the encryption method for the transmission data. TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This insures much greater security than the standard WEP security.

  • Page 20: Statistics

    Parameter Description Current Tx Rate Display the transmission rate of the network. The maximum transmission rate is 54Mbps. Throughput (Kbits/sec) Display the speed of data transmitted and received. Link Quality This bar indicates the quality of the link. The higher the percentage, the better the quality.

  • Page 21: Advance

    Advance This option enables you to configure more advanced settings, for example: wireless mode, protection mode and etc. Parameter Description Wireless Mode 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.

  • Page 22: About

    Parameter Description ADHOC_OFDM When the network type is in Ad Hoc mode, that the card can only work in 11b data rate. It is defined by Wi-Fi organization. If you want to enable the data rate up to 54Mbps (11g), select “ADHOC_OFDM”.

  • Page 23: Troubleshooting

    4 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the card. 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.
  • Page 24 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.
  • Page 25 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.
