 -24- 4-2 Use the WLAN Utility The WLAN Utility enables you to make configuration changes and perform user-level diagnostics on your 11Mbps Wireless LAN PC Card in the Windows XP/2000/NT/98/ME operating system environments.  The WLAN Utility consists of window with 5 items for you to monitor and configure the 11Mbps Wireless LAN PC Card:  Configuration, Link Test, AP Browser, Site Survey and About.   Configuration: The Configuration item allows you to modify the configuration parameters for the 11Mbps Wireless LAN PC Card such as Profile, Network Type, Ad-Hoc Channel, Transmit Rate, ESSID, WEP, RTS/CTS,  Fragment Threshold, and  Power Save mode.  Furthermore, you may monitor the current status of the Wireless LAN PC Card such as State, Current Channel, Current Tx Rate, Throughput, Link Quality and Signal Strength.
 -25- Profile The Profile field allows you to set values for all parameters by selecting a previously defined profile.  To create the profile, go to the Profile field, type a profile name and set the corresponding parameters.   If one of the profiles is no longer used, you may remove it by clicking the  Delete button.  After changing parameters, save the profile and click the  Apply button to take effect.  You can have multiple profiles and modify the profile at any time.   Alternatively, you may choose the profile by right clicking the system tray icon on the task bar, making the configuration more friendly and efficient.  Network Type There are 3 network types for the 11Mbps Wireless LAN PC Card to operate.  If you need to access company network or Internet via Access Point, select “Infrastructure”.  To set up a group of wireless stations for file and printer sharing, select “Pseudo AdHoc” or “802.11 AdHoc” (without Access Point).  If Pseudo Ad-Hoc (without access point) is selected, you need to set wireless stations with the  same channel.  For  802.11 AdHoc, the  same ESS ID is required to the wireless stations.  You may right click the WLAN system tray icon to choose the pre-set profiles
 -26- ESSID The ESS ID is the unique ID used by Access Points and stations to identify a wireless LAN. Wireless clients associating to any Access Point must have the same ESSID.  The default setting is ANY, which allows your Wireless LAN PC Card to automatically associate to any Access Point (Infrastructure mode) in the vicinity of your wireless adapter.  Alternatively, you may check the ESS ID check box to specify the ESS ID.  It will then attempt to associate with Access Points or stations with the same ESS ID.  The ESS ID can be set up to 32 characters and is case sensitive.    Check here before entering the ESS ID If there two Access Points with the same ESSID, you may check the BSS ID check box and enter the MAC address of the Access Point you desire to connect to.  Check here before entering the BSS ID  Transmit Rate The 11Mbps Wireless LAN PC Card provides various data rate options for you to select.  Data rates options  include Fully Auto,  2 Mbps, 1 or 2 Mbps, 5.5 Mbps, and 11 Mbps.  In most networking scenarios, you will see that the factory-set default “Fully Automatic” will prove the most efficient.  This setting will allow your 11Mbps Wireless LAN PC Card to operate at the maximum data rate.  When the communications quality drops below a certain level, the PC Card will automatically switch to a lower data rate.  Transmission at lower data speeds are usually more reliable.  However, when the communications quality improves again, the 11Mbps Wireless LAN PC Card will gradually increase the data rate again, until it has reached the highest available transmit rate.
 -27- WEP  To prevent unauthorized wireless stations from accessing data transmitted over the network, the WLAN Utility offers highly secure data encryption, known as WEP, making  your data transmission over air more secure.  To activate the WEP Encryption, check the WEP Enabled check box.  An Encryption window will then appear.  The instructions are as follows: Ø Pull down the Encryption (WEP) menu and select either 64bit or 128bit encryption method. Ø Specify the encryption keys.  There are two methods to set the WEP keys, as described below: Create Encryption Keys by Using a Passphrase   To create encryption keys by using a passphrase, click the Create Key with Passphrase check box and type a character string in the Passphrase field.  As you type, the utility uses an algorithm to generate 4 keys automatically.  Select either the 64bit or 128bit encryption first, and type a string in the Create Key with Passphrase field.  Select one key from the 4 WEP keys and click OK.  Then click the Apply button on the Configuration tab to make the setting take effect.  Create Encryption Keys Using a Passphrase (128bit)
 -28- Create Encryption Keys Manually You can also create encryption keys manually by clicking the  Create Keys Manually check box.   For 64bit encryption you may choose: n Alphanumeric: 5 characters (case sensitive) ranging from  “a-z”, “A-Z” and “0-9” (e.g. MyKey) n Hexadecimal:  10 hexadecimal digits  in the range of “A-F”,  “a-f”  and “0-9” (e.g. 11AA22BB33) For 128bit encryption you may choose: n Alphanumeric: 13 characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (e.g. MyKey12345678) n Hexadecimal: 26 hexadecimal digits  in the range of “A-F”,  “a-f”  and “0-9” (e.g. 00112233445566778899AABBCC).  After entering the WEP keys in the key field, select one key as active key, click the OK button and then click the Apply button on the Configuration tab to make the setting take effect.  Create Encryption Keys Manually (64bit)  Note: The WEP key must be set up exactly the same on the Wireless LAN stations as they are on the wireless Access Points.  If you set “MyKey” for the Wireless LAN PC Card, the same WEP Key “MyKey” must be assigned to the Access Point or other stations.
 -29- Advance The WLAN Utility also offers the advanced configuration for user to set the 11Mbps Wireless LAN PC Card under certain network environment.  These advanced options include Power Management, RTS/CTS and Fragmentation Threshold.  To enable the advanced configuration, go to the Configuration tab and click the Advance button.  Power Management The Power Save option is designed to conserve battery life of you computer.  When Power Save is enabled, your 11Mbps Wireless LAN PC Card will go into sleep mode to minimize power consumption. Note: When power saving mode is enabled, the Access Points you use need to support power saving as well so that the communication can be established.   RTS Threshold RTS Threshold is a mechanism implemented to prevent the  “Hidden Node” problem.  “Hidden Node” is a situation in which two stations are within range of the same Access Point, but are not within range of each other.  The following figure illustrates an example of the  “Hidden Node” problem.  Both stations (STA) are within range of the Access Point, however, they cannot hear each other.  Therefore, they are hidden nodes for each other.  When a station starts data transmission with the Access Point, it might not notice that the other station is already using the wireless medium.  When these two stations send data at the same time, they might collide when arriving simultaneously at the Access Point.  The collision will most certainly result in a loss of messages for both stations.
 -30-          Thus, the RTS Threshold mechanism provides a solution to prevent data collisions.  When you enable RTS Threshold on a suspect “hidden station”, this station and its Access Point will use a Request to Send/Clear to Send protocol (RTS/CTS).  The station will send an RTS to the Access Point, informing that it is going to transmit the data.  Upon receipt, the Access Point will respond with a CTS message to all station within its range to notify all other stations to defer transmission.  It will also confirm the requestor station that the Access Point has reserved it for the time-frame of the requested transmission. If the “Hidden Node” problem is an issue, please specify the packet size.  The RTS mechanism will be activated if the data size exceeds the value you set.  It is highly recommended that you set the value ranging from 0 to 1500.  The default value is Disable.   Note: Enabling RTS Threshold would cause redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.   Frag. Threshold Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network.  If your 11Mbps Wireless LAN PC Card often transmit large files in wireless network, you can enable the Fragmentation Threshold by clicking the  Enable button and the mechanism will split the packet.  The value can  be set from 256 to 1500.  The default value is Disable.  IRQ NO./IO Address To avoid device conflict, you may modify the IRQ No. and IO Address for your device (Only available under Windows NT).
 -31- Status: The Status field on the Configuration menu provides the following information.  State: When operating in Infrastructure mode, this field shows the MAC address of the Access Point with which the Wireless LAN PCMCIA Card is communicating.  When operating in Ad-Hoc mode, it shows the virtual MAC address used by computers participating in the Ad-Hoc network. Current Channel: Shows the channel on which the connection is made. Current Tx Rate: Shows the highest transmit rate of the current association. Throughput: Shows the short term transmit and receive throughput in bytes/second, and is continuously updated. Link Quality: Based on the quality of the received signal of the Access Point beacon.  There are 5 states of link quality: 100%~80%: Excellent link. 80%~60%: Good link quality. 60%~40%: Fair link quality. Under 40%: Poor or no connection. Signal Strength: Based on the received signal strength measurement of the baseband processor of the Beacon signal.  Same as link quality, there are 5 states of signal strength: 100%~80%: Excellent signal strength. 80%~60%: Good signal strength. 60%~40%: Fair signal strength. Under 40%: Poor or no signal strength. You can click the Rescan button to force the radio to rescan all available channels.  If your link quality or signal strength is poor, rescanning can be used to push the radio off a weak Access Point and search for a better link with another Access Point.
 -32- Link Test: The Link Test tool helps you examine data transmission quality between your 11Mbps Wireless LAN PC Card and any workstation on the network.   By entering IP address of 2 remote station, setting ping interval and packet size, you may know whether communication has been made successfully or not.  Additionally,  you  may run the loopback test by clicking the Look back button to verify the communication quality between your wireless station and Access Point.  The Refresh button is used for setting the counters back to 0.  AP Browser: By clicking the  Rescan button, the AP Browser can display Access Points around the working environment.  Besides showing the ESSID of each Access Point, it also displays BSSID, Channel, Signal, Quality and Supported Rates.  To join any of the displayed Access Points, highlight the Access Point you desire to connect and then click the Join BSS (when there are more than 2 Access Points with the same ESSID), or Join ESS button to join the group.
 -33- Site Survey: When the  Site Survey screen is displayed, the channel quality of all 14 radio channels will be displayed.  These channel quality measurements are shown on each gauge for the 14 radio channels.  The blue bar indicated the channel quality is clear and good.  The higher the blue bar is, the better quality you have (i.e., less interference).  The yellow bar indicates the channel quality is fair and the red bar indicates the channel is busy or having severe interference.  About: The About item shows the versions of the Wireless LAN Utility, driver, firmware of the 11Mbps Wireless LAN PC Card.  Also, the MAC address and frequency domain are displayed.
