Chapter3. Using The Utility
The Wireless LAN Monitor Utility enables you to make configuration changes on your
11Mbps Wireless LAN Card. The Wireless LAN Utility consists of window with 5 items for
you to monitor and configure the 11Mbps Wireless LAN Card: Info, Status, Configuration,
Encryptions and About.
3-1. Info:
The Info tab shows you the current Link State of Wireless LAN Card and Reachable
Access points and Stations in the wireless environment.
Link State: There are five kinds of states for a Wireless LAN Card:
Access Point associated: The wireless LAN card is now connecting to an Access Point.
Peer-to-Peer associated: The wireless LAN card is joining a Peer-to-Peer network now.
Access Point scanning: The wireless LAN card now search for an Access Point with the
same network name, or SSID to connect.
Peer-to-Peer scanning: The Wireless LAN Card now searches for another Wireless LAN
7
Card with the same SSID and the same channel to join.
WEP security rejection: This will occur if you join an wireless network with incorrect WEP
key.
The other items in the table are details about the link state and will only be available
when the wireless LAN card is associated with an Access Points or other wireless LAN
card.
SSID: This is also known as network name.
BSSID: This is the MAC address of the Access Point when the Wireless LAN Card
connects an Access Point or a special serial number when the Wireless LAN Card is in
Peer-to-Peer mode.
Channel: This represents the channel now used by the Wireless LAN Card.
TxRate: This represents the transmission rate now the Wireless LAN Card uses.
Signal Quality: This is only available in Access Point mode and represents the quality of
communication between the Wireless LAN Card and Access Point.
Reachable Access Points / Stations:
This item will show you all the other 802.11 Access Points or Wireless LAN Card s in your
wireless environment. The icon in the front of every item represents this point is an Access
Point or a Wireless LAN Card in Peer-to-Peer mode. One can join a network easily by
clicking the SSID which you want to join.
Refresh: Clicking this button, the wireless LAN card will rescan the wireless environment
an show you all the newest reachable Access Points and Stations.

3-2. Status:
The Status tab will show you the detailed status of the wireless net card.
State
This field is used to display the current state of the Wireless LAN Card. When the state is
“Associated “ means normal flow of operation in Infrastructure mode. The PC is connected
to access point. BSSID is shown in the form of hex digits. Networking is available. A state of
“Scanning ” means that the node is searching for available access point and unable detects
the SSID for an available access point within range. This field will also display an error
message if for some reason the driver failed to initialize.
Rescan
Pressing the rescan button causes the driver to restart and begin its Connection Procedure.
The connection procedure differs depending on the Mode of the driver.
Access Point Mode - The driver will scan all available channels continuously until it finds
one or more Access Points that matches its SSID. At that point it will try and authenticate
and associate with the Access Point.
Point-to-Point Mode - The driver will scan for 5 seconds looking for an existing Ad Hoc
networking the same SSID.
Current Channel and Tx Rate
Shows the channel of the radio and transmit rate are being currently used for an active
connection. This value has no meaning when the radio is “Scanning”
Throughput
9
These two fields display the instantaneous wireless Receive and Transmit throughput
displayed in bytes per second. These values are updated every two seconds.
Link Quality
The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar
graphically displays the quality of the link between the node and its Access Point. A label
summarizes the quality of the link over the bar graph, which can take on one of the
following values:
“Poor”
“Weak
“Fair”
“Good”
“Excellent”
Signal Strength
The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The
bar graphically displays normalized signal strength as reported by the radio, averaged over
all frames over 100 bytes long that are received from the Access Point.
3-3. Configuration:
The Configuration Tab contains several fields where operating parameters of the driver
can be viewed or changed. Changes to any of the parameters in this panel can be applied
to the driver without the need to reboot the PC.
Defaults: Pressing this button restores each field in the panel to its default value. The
Apply Changes button or OK must be pressed before the default values are saved to the
driver and registry.
10
Profile: You can save various wireless settings for different environment. The system
allows you to have 5 different configurations.
Network Name: It is also known as SSID and is the unique name shared among all points
in the wireless network. The SSID must be identical for all points in the network. It is case
sensitive and must not exceed 32 characters.
Network Type:
This field allows you to select from a list of supported Network “Modes”. The modes
displayed have two values: “Peer-to-Peer” and “Access Point”.
Peer-to-Peer: This is the 802.11 peer-to-peer mode of operation. All communication is
done from Client to Client without the use of an Access Point. Peer-to-Peer networking
uses the same SSID for establishing the wireless connection.
Access Point: This mode of operation requires the presence of an 802.11 Access Point.
All communication is done via the Access Point, which relays packets to other wireless
Clients in the BSS as well as to nodes on a wired network such as Ethernet.
Peer-to-Peer channel: This specifies the channel used in wireless communication and
should be set to same channel as the other points in the wireless network. This setting can
only be adjusted in Peer-to-Peer mode.
TX Rate: The transmission rate at which client of AP transmits the data packets. You may
set this to Auto 1 or 2 Mb, 5.5 Mb, 11 Mb, or Fully Automatic.
3-4. Encryption:
To prevent unauthorized wireless stations from accessing data transmitted over the
network, the 11Mbps Wireless LAN Card offers highly secure data encryption, known as
WEP (Wired Equivalent Privacy). If you require high security in transmission, go to the
Encryption tab and do the following.
¾ Pull down the Encryption menu and select either 64bit or 128bit encryption method.
¾ Specify the encryption keys. There are two methods to set the WEP keys, as
described below:
11
From the WEP encryption item, pull down the menu and it will list three options:
Disable – Allows wireless adapters communicate with Access Points without any data
encryption.
64 Bit – Requires wireless stations to use data encryption with 64 Bit algorithm when
communicating with the Access Point.
128 Bit – Allows wireless clients to communicate with the Access Point with 128 Bit
encryption algorithm.
The Encryption tab enables you to identify up to 4 different encryption keys and select one
of them to encrypt your transmission data. The key value of your choice may either be:
For 64-bit encryption:
Five alphanumeric characters in the range of “a-z”, “A-Z” and “0-9” (e.g. MyKey)
10 digit hexadecimal values in the range of “A-F” and “0-9” (e.g. 11AA22BB33).
For 128-bit encryption:
13 alphanumeric characters in the range of “a-z”, “A-Z” and “0-9” (e.g. WEPencryption).
26 digit hexadecimal values in the range of “A-F” and “0-9” (e.g.
11AA22BB33123456789ABCDEFF).
Alternatively a Passphase can be entered which is used as a “seed” to randomly
generate the four keys. This saves considerable time since the same keys must be entered
into each node on the wireless network.
Key 1 – Key 4
These four fields can be used to manually enter the keys. This may be necessary if you
wish this node to match keys in a different vendor’s product. These fields also display the
12
keys when they are generated using a Pass-phrase.
3-5. About:
About tab shows the product version including the detail of Driver, Configuration Utility, and
NIC firmware version. Users must use this version number when reporting their problems to
technical support.
