A beep should be heard if the adapter isproperly inserted.§ Check the I/O cable that connects the RF module and the card. The power LED indicatorwill be active if the cable is properly connected.§ For non-Windows 95/98 environments, ensure that driver is installed in your computer.§ 1) Click on the Control Panel and then on PC-Card. Check whether it has the card in oneof the sockets or not. If you find PC-Card Adapter in one of the sockets, it means the cardis detected properly. If you see the yellow sign of§ question-mark(?), the resources are conflicting.§ 2)Right click on “My Computer” and the select Properties. Select the device Manager andclick on the Network Adapter. You will find PC-Card Adapter if it is installed successfully.If you see the Yellow sign the resources are conflicting. Click on and then on service,you can see the status of. If there are yellow sign either on adapter or, please checkfollowings.§ 2-1) Check if your Notebook supports 3.3V card.§ 2-2)Check if your Notebook has a free IRQ§ 2-3) Check that you have inserted the right card and have installed the proper driver.If the GL242204-0T does not function after attempting the above steps, remove the , and do thefollowing:§ From the run window enter, c:\windows\system, locate and delete the cw10.sys file
40§ Open the “Control Panel” double-click “System” and delete PC-card Adapter.§ Restart the PC and repeat the hardware and software installation steps outlined inChapters 3 and 4.The GL242204-0T station cannot communicate with other computers linked via Ethernet inthe Infrastructure configuration.Probable Solution:§ Ensure that the GL242204-0T with which the station is associated is powered on.§ Confirm the station is configured with the same operating radio channel as the GL242204-0T. If the IDs are different, change the GL242204-0T and all the stations within the BSS toanother radio channel.§ Ensure that the station is configured with the same security options as the GL242204-0T,and can be turned off and on with the same security key.§ Confirm that the BSS ID is the same as the GL242204-0T for a roaming disabled station.Alternately confirm that the ESS ID is the same as the GL242204-0T for a roaming enabledstation.
41Access Point appendix B GlossaryAccess 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 anindependent wireless LAN without an access point to make point-to-point wireless communication.ATIM – It means "Announcement Traffic Indication Message". A station may enter power save mode if and only ifthe value of the ATIM Window in use within the IBSS (in Ad hoc mode) is greater than zero. If this valueis NULL, no power management is used within IBSS created by the station.Authentication Type – The Authentication Type controls the WEP key validation during the authentication ofa station by the access point. When the Shared Key option is selected, the access point will validate thatthe station is using the same WEP key with it. This procedure goes like this: the access point sends aknown unencrypted packet to the station. The station encrypts this packet and sends it back to theaccess point. The access point tries to decrypt this packet and then sends an Authentication responsepacket to the station indicating the success or failure of this process. On the other hand, under OpenAuthentication, there is no check for a matching WEP key.Backbone - The core infrastructure of a network, the portion of the network that transports information from onecentral location to another central location. The information is then off-loaded onto a local system.Base Station - In mobile telecommunication, a base station is the central radio transmitter/ receiver thatmaintains communication with the mobile radio telephone sets within range. In cellular and personalcommunications Applications, each cell or micro cell has its own base station; each base station in turnis interconnected with other cells’ base.BSS - Stands for “Basic Service Set.” An Access Point associated with several wireless stations.ESS - Stands for “Extended Service Set.” More than one BSS can be configured as an Extended Service Set. AnESS is basically a roaming domain.Ethernet - A popular local area data communications network, originally developed by Xerox Corp., whichaccepts transmission from computers and terminals. Ethernet operates on 10 Mbps base bandtransmission over shielded coaxial cable or over shielded twisted pair telephone wire.Fragmentation Threshold – The Fragmentation Threshold defines the number of bytes used for thefragmentation boundary for directed messages. The purpose of "Fragmentation Threshold" is toincrease the transfer reliability thru cutting a MAC Service Data Unit (MSDU) into several MAC ProtocolData Units (MPDU) in smaller size. The RF transmission can not allow to transmit too big frame size dueto the heavy interference caused by the big size of transmission frame. But if the frame size is too small,it will create the overhead during the transmission.Infrastructure - An integrated wireless and wired LAN system is called an Infrastructure configuration.Listen Interval – The Listen Interval field is used to indicate to the ACCESS POINT how often a station wakesto listen to Beacon management frames. The value of this parameter is the station's Listen Interval MIBattribute and is expressed in units of Beacon Interval. The length of the Listen Interval decides the wakeup time to listen to Beacon management. Longer Listen Interval decreases the performance and shorterinterval decreases power saving function.PCMCIA - Personal Computer Memory Card International Association, which develops standards for PC cards,formerly known as s, are available in three “types” which are about the same length and width as creditcards, but range in thickness from 3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III). These
42cards can be used for many functions, including memory storage, as landline modems and as wirelessLAN.Preamble Mode – Preamble is a sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reachsteady-state demodulation and synchronization of bit clock and frame start. Two different preambles andheaders are defined: the mandatory supported Long Preamble and header, which interoperates with the1 Mbps and 2 Mbps DSSS specification (as described in IEEE Std 802.11), and an optional ShortPreamble and header (as described in IEEE Std 802.11b). At the receiver, the Preamble and header areprocessed to aid in demodulation and delivery of the PSDU. The Short Preamble and header may beused to minimize overhead and, thus, maximize the network data throughput. However, the ShortPreamble is supported only from the IEEE 802.11b (High-Rate) standard and not from the original IEEE802.11. That means that stations using Short-Preamble cannot communicate with stations implementingthe original version of the protocol.Roaming - A function that allows one to travel with a mobile end system (wireless LAN mobile station, forexample) through the territory of a domain (an ESS, for example) while continuously connecting to theinfrastructure.RTS Threshold – Transmitters contending for the medium may not hear each other. The RTS (Request ToSend) Threshold defines the number of bytes used for the RTS/CTS (Clear to Send) handshakeboundary. The small setup value will cause the overhead during the transmission and too big setupvalue will decrease the transfer reliability. So normally the value should be default in 2432 bytes. Byinconsistent data flow, try to minor the value. The RTS/CTS mechanism can solve this “ Hidden NodeProblem”.WEP – Wired Equivalent Privacy (Wep) is an encryption scheme used to protect wireless data communication.Selecting “Disabled” will prevent you from sharing data with other computers if your network uses Wep.If your network is Wep enabled, you must choose “64 bits” or “128 bits”. Consult your SystemAdministrator for more information about your network type. For more information about Wep, see theChapter entitled “PRISM Configuration Utility” in this manual.
