User manual SAGEM WPCB-128GW PCMCIA CARD

[. . . ] Infrastructure Networking In this mode, the radio links are coordinated by an Access Point providing connection with an existing wired network and other network facilities such as Internet, email, shared devices. . . Also known as peer to peer networking, this mode allows easy connection between wireless workstations, to act as servers to all others. Ad-hoc Networking Wireless Network Ad-hoc Infrastructure Access Point Wired Network Package Content 1 These are the items included in the package: One SAGEM Wi-Fi 11g CARDBUS ADAPTER One Quick Start Guide One installation CD-ROM Minimum System Requirements Personal Computer with an available CARDBUS slot. Microsoft Windows 98 Second Edition (98SE), Windows Millennium (ME), Windows 2000 or Windows XP installed on the PC. SAGEM Wi-Fi 11g CARDBUS ADAPTER for wireless networking The installation of your SAGEM Wi-Fi 11g CARDBUS ADAPTER for wireless network requires three steps: Software installation Hardware installation Wireless connection configuration Installation of the software under Windows : Warning: It is necessary to install the Wireless Networking software and drivers BEFORE plugging the CARDBUS card in the appropriate slot of your computer. The first step of the installation is to copy all the necessary files to your hard disk. [. . . ] It is case sensitive (please take great attention to that). Configuration of the Encryption parameters To prevent unauthorized wireless station from accessing data transmitted over your network, the Wireless LAN offers secures data encryption, like "open" and "shared Key" authentication with WEP (Wired Equivalent Privacy) encryption or WPA-PSK (Wi-Fi Protected Access ­ Pre Shared Key) authentication with TKIP (Temporal Key Integrity Protocol) encryption. The activation or not of the security has to be set on the same way on the Access Point and on your LAN CARDBUS (client station). Your network can only be operated in the 2 following conditions: No security activated, neither in the Access Point, neither in the client stations Security activated (recommended for securing your data) in the Access Point and on all client stations with the same characteristics of encryption. If your Access Point works without security, your wireless LAN also has to be set without WEP or WPA. Check in the main screen of the Utility that the Security Type list is set to Disable. 2) Security enabled on Access Point. Beware that if you enable security on your , you necessarily have to enable the type of security on the Access Point side, as well, if you want your to be able to associate with it. Go the Configure tab in the main screen of the Utility and select in the Security Type list the wanted security type. Here we will explain how to configure open security with WEP and WPA-PSK security with TKIP. 2. 1) WEP encryption : In the screen " Configure", you will have to : Security Type is fix to WEP 64 bits or 128 bits select the index key select the way to generate the encryption keys (from a passphrase or manually) Length of the WEP keys WEP protocol offers two levels of encryption: encryption based on 40 or 64 bits key length and more secure encryption based on 104 or 128 bits key length. The 40 bits keys and the 64 bits keys are the same, if their effective length is 64 bits, only 40 bits are selected by the user, the others bits are automatically calculated. The principle of management is identical for both 64 bits and 128 bits. The key length has to be set at the same value on the Access Point and on the client station (Wireless LAN in our case). 6 Creation of the WEP keys It is possible to manually enter the WEP key you want to use. However, this entry being rather tedious, especially for 128 bit keys, it is possible to have them generated automatically. To do that, you will have to enter a string of characters called "Passphrase". Create Encryption Keys by Using a "Passphrase" 1- Select first the "WEP (64 bits)" or "WEP (128 bits)" length of the key. 3- Select index key (fixed to 1 for WEP 128 bits) 4- Enter the string in PassPhrase. 5- Finally click the "Apply button" in the Configure tab to save the configuration. Warning: when Create Key with Passphrase is enabled, the wireless device's Key number with PassPhrase must match the Key number with PassPhrase used by the access point with which wireless devices are going to communicate. Create Encryption Keys Manually You can also create up a encryption key. Select first the "WEP (64 bits)" or "WEP (128 bits)" length of the key to generate 2. Select "ASCII" or "Hex" (hexadecimal) in Key Type 3. [. . . ] Then click the "Apply" button on the Configure tab to make the setting take effect. If you want to create a new Wireless Ad Hoc network, select an unused channel, then click the "Apply" button on the Configure tab to make the setting take effect. Configuration of WEP encryption The configuration of WEP encryption in Ad Hoc mode is similar to the one in Infrastructure Mode. The configuration of your Wireless LAN in Ad-Hoc mode is finished. 9 About Status Information on your Wireless LAN CARDBUS Card Led Indicators The CARDBUS card has two LED indicators giving the following information on the link status : One should be solid green when the card is power on and the cardbus wireless adpater driver is activated. The other one is blinking green when the cardbus wireless adpater is transmitting data. I. [. . . ]
