3-3 GL242201-0T DRIVER INSTALLATION -WINDOWS® 95/98 Note: Before proceeding, have the Windows® 98 CD ready, as it will be required during the software installation process. 1. Insert the GL242201-0T into a standard Type II or Type III slot, as described in the preceding section. 2. Windows® 98 will automatically detect the GL242201-0T and prompt you to install the necessary driver. Click “Next” to begin the installation. 3. Check “Search for the best driver… “and click “Next”. 4.
Windows® will now install the driver As the driver files are being copied to the Access Point appropriate location, you will be prompted to insert the Windows® 98 CD. 6. Insert the Windows® 98 CD. Select “D:\win98” from the drop down list (where “D” represents the CD-ROM drive), click “OK”. NOTE: You must insert the Windows 98®CD as the driver installation requires special files that will not be available even if you have stored a copy of Windows® 98 on your hard drive. 7.
10. Select " TI ACX100 WLAN Adapter" from the list and press the “Properties” button. 11. From the “Properties” menu, please select the “Advanced” tab. 12. From the menu, please select “Advanced” tab. First, Select “ Authentication Mode” and set up either “Auto Switch”, “Open Authentication” or “Shared Authentication”.
6. Select “Channel” from the list, and choose a “Value” from the drop down list. FCC regulations require a “Value” between 1 and 11. 7. Select “Desired SSID” and create the network name that matches the existing one or starting a new one. The SSID can have any value, but should have the same value as the Access Point. In Ad-Hoc mode, all clients should share the sameSSID. SSID In infrastructure association, the stations will link to the AP with the same ESSID as they have. 8.
21. “Driver Description” indicates the name of the driver. 21. “Firmware File” provides the file name for the firmware. 21. Select “Fragmentation Threshold” and set up a default value: 2432. The value indicates how much of the network resources devoted to recovering packet errors. The value should remain at its default setting of 2432 bytes. If you have decreased this value and experience high packet error rates, you can increase it again, but will likely decrease overall network performance.
21. You may enter “Network Address” if you would like to specify the address. By default, it is set to “Not Present”. 21. Select “Power Mode” to indicate if you would like to select “Continuous Access Mode” to continue to have the device on without any power saving. To select “Fast Power Save” so the device will remain the speed of the network while perform the power saving. “Maximum Power Save” allows the device in stand by mode and wakes whenever there’s a signal being detected. 21.
15. RTS Threshold: The value should remain on its default setting 2432 bytes. If you encounter any date flow, only minor modifications are recommended. 16. “Rx Descriptors” means the receiving butter for your netw orks throughput. The greater value will cause data loss where the less value will decrease the networks performance. The default is set to 32. 17.
18. “Tx Descriptors” means the transmitting butter for the network’s throughput. The greater value will cause data loss where the less value will decrease the networks performance. The default is set to 32. 19. “WEP Option” means this will display the status of encryption protocol. It can be “Off”, if the WEP encryption protocol is not enabled. When it is necessary to use, it will be set to “O n”. Wired Equivalent Privacy (WEP) is an encryption scheme used to protect wireless data communication.

Chapter 4 Installing & Navigating the Configuration Utility 4-1 CONFIGURATION UTILITY The following section describes and defines the various functions of the Configuration Utility. This utility provides quick access to all adapter settings. Quick-Launch Icon: After installation is complete, launch the program and a utility icon will Access Point appear in the “Quick-Launch” menu in the lower right hand corner of the screen, near the clock.
Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration. Prefered SSID - This will display the name that is shared with all the stations in your wireless network system. Tx Rate - The basic transfer rate is to set based on the speed of the wireless network system. For slower network system is to be selected 1or2 Mbps and faster network 5.5, 11 or 22 Mbps.
4-2 ADVANCED C ONFIGURATION In the Advanced Configuration menu you may: Antenna Configuration Transmit – You may select “Antenna 1”, “Antenna 2” or “Both” if you would like to have both antenna to perform the same function. Receive - You may select “Antenna 1”, “Antenna 2” or “Both” if you would like to have both antenna to perform the same function. Retry Limits Short Retries – By default it is set to “7” will be the best number to retry to minimize the network overhead.
4-3 NETWORK CONFIGURATION An IP address can be automatically assigned to this computer. If your network provider requires y ou to manually set the IP address for this machine, you may do so by click on “Specify an IP address” then enter the address and the Subnet Mask. Click “Next” to continue. If your network provider has supplied DNS information, you may click on “Enable DNS” then enter the “Primary Server”, “Alternate Server”, “Host Name”, “ Domain” name and “Domain suffix search”.

Appendix A Troubleshooting Problem Solving My computer does not recognize the GL242201-0T. Probable Solution: § The GL242201-0T is not properly inserted into the Card Bus slot. § Ensure that the GL242201-0T has been inserted into an available Card Bus slot. The GL242201-0T does not work properly. Probable Solution: § Insert the card into Notebook’s slot again. A beep should be heard if the adapter is properly inserted. § Check the I/O cable that connects the RF module and the card.
§ Open the “Control Panel” double-click “System” and delete PC -card Adapter. § Restart the PC and repeat the hardware and software installation steps outlined in Chapters 3 and 4. The GL242201 -0T station cannot communicate with other computers linked via Ethernet in the Infrastructure configuration. Probable Solution: § Ensure that the GL242201-0T with which the station is associated is powered on. § Confirm the station is configured with the same operating radio channel as the GL2422010T.
Access Point appendix B Glossary Access Point - An internetworking device that seamlessly connects wired and wireless networks together. Ad-Hoc - An Ad-Hoc wireless LAN is a group of computers each with wireless adapters, connected as an independent wireless LAN without an access point to make point-to-point wireless communication. ATIM – It means "Announcement Traffic Indication Message".
cards can be used for many functions, including memory storage, as landline modems and as wireless LAN. Preamble Mode – Preamble is a sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach steady -state demodulation and synchronization of bit clock and frame start. Two different preambles and headers are defined: the mandatory supported Long Preamble and header, which interoperates with the 1 M bps and 2 Mbps DSSS specification (as described in IEEE Std 802.
