1 Introduction Thank you for purchasing the Wireless LAN PCI Card. This card features the latest innovation wireless technology. IEEE 802.1x which request wireless stations to pass the authorization by entering a unique user name and password designated by the authorization server before connecting to the wireless devices such as Access Point or Router. TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard) which are advanced WLAN security technology included in the IEEE 802.
1.3 Package Contents Before you begin the installation, please check the items of your package. The package should include the following items: O One PCI Card O One Antenna O One Quick Guide O One CD (Driver/Utility/Manual) If any of the above items is missing, contact your supplier as soon as possible.
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 Windows 2000. (Procedures will be the same for Windows 98SE/Me.) Note2: If you have installed the Wireless LAN PCI Card driver & utility before, please uninstall the old version first. 2.1.1 Install the Driver 1. Turn off your PC. 2.
3. Click "Finish" to complete the installation. 4. When you complete the Utility installation, a shortcut named “Rtl8180“ will appear in the computer’s desktop and a new icon will display in the system tray at the bottom of the screen. Double click the shortcut or the icon and start using the WLAN PCI Card. In the Desktop 2.2 In the system tray 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.
B. Using the Utility of this card 1. Get into Windows XP’s Utility, click “Advanced“ button. 2. On the “Wireless Networks“ tab in the “Wireless Network Connection Properties“ screen, clear the “Use Windows to configure my wireless network settings“ check box. If you want to enable the Windows XP built-in utility, select the check box again. 3. Double click the shortcut or the icon in the system tray and start using the WLAN PCI Card.
Note: If you don’t disable the XP’s Utility, you can still see the link status and statistics during communication process from the card’s utility.
3 Configuration Utility The Configuration Utility is a powerful application that helps you configure the Wireless LAN PCI Card and monitor the link status and the statistics during the communication process. This utility can be used to change the following configuration parameters when the device is active. 3.
Parameter Description Connect Button Click the button to connect to the selected network. Cancel Button Click the button to cancel the wireless network connection. 3.2 Configuration This screen is for you to make advanced setting in order to connect to an available network or create a new wireless network connection. You could also define the connection order here. Parameter Description Profile Display the profiles the card is connecting to.
Parameter Description Available Wireless Network(s) Configure Button If you are unable to conect to an existing wireless network, click the network name and then click this button. The “Wireless Netowrk Properties“ will show up for you to configure the card and ensure the settings are correct. Refresh Button To update the list of available networks, click the “Refresh“ button. Available Profile(s) This list shows the preferred networks for the wireless connection.
Parameter Description Network Name(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. Only the wireless devices with the same SSID can interconnect. Wireless Network Key(WEP) WEP is an authentication algorithm, which protects authorized Wireless LAN users against eavesdropping. The security setting must be the the same on the wireless stations within the network.
Parameter Description Wireless Network Key(WEP) Network Key If the network is required for Wired Equivalent Privacy (WEP) key, type the key in the text box. The key should be 10 or 26 hexadecimal characters according to the WEP mode designated by the network. Note: The hexadecimal characters include the range of “A-F”, “af” and “0-9”, for example: “0123456aef“ or “01234567890123456789abcdef“. Confirmed Network Key Enter the same network key again to cofirm the key.
Parameter Description Ad Hoc Default Channel Select the number of the radio channel used for the Ad Hoc networking. The channel of all the wireless stations in the Ad Hoc network should be the same. The parameter is not active in the infrastructure operation mode. Note: The Infrastructure operation mode requires the presence of an 802.11 Access Point. All communication is done via the Access Point. Encryption Algorithm The parameter is only active in the Ad Hoc operation mode.
Parameter Description Preamble Mode The preamble defines the length of the CRC block for communication among the wireless stations. There are three mode including Long, Short and Auto. High network traffic areas should use the shorter preamble type. If “Auto“ mode is selected, the card will auto switch the preamble mode depending on the wireless stations which the card is connecting to. Note that the parameter is only active in the Ad Hoc operation mode.
3.5 Statistics You can get the real time information about the packet transmission and receiving status during wireless communication from the screen. If you want to recount the statistics value, please click “Reset“ button.
3.6 About This screen displays the version and the designer of the Utility.
4 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the card. 1. What is the IEEE 802.11b standard？ The IEEE 802.11b Wireless LAN standard subcommittee which formulates 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.
8. What is AES? AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the highest degree of security and authenticity for digital information, wherever and however communicated or stored, while making more efficient use of hardware and/or software than previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES, TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at the hardware level. 9.
12. 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.
