Link Quality is based on the percentage of successfully transmitted or received signal of the
associated access point beacon within a limited period. The higher the percentage, the better the
link quality. The bar graph beside also provides a visual interpretation of the current link quality. It is
noted that the Link Quality and Signal Strength features only apply to the Infrastructure mode.
They are inapplicable in the Ad-Hoc mode since data will be transferred from many different
computers.
Signal Strength
You may learn the received signal strength of the baseband processor of the beacon signal from the
Signal Strength bar beside, and it’s also presented in terms of percentage. As the signal gets
stronger, the signal percentage rate gets higher. It is noted that the Signal Strength and Link
Quality features only apply to the Infrastructure mode. They are inapplicable in the Ad-Hoc mode
since data will be transferred from many different computers.
The Configuration Tab
Click this tab to edit different profiles for different network configurations. When finish changing the
settings, please click Apply to perform the new configuration at last.
Note: Choosing the Advanced Configuration command from the right -click menu of WLAN PRISM3
IEEE802.11b tray icon will launch this tab too.
Figure 4.3-3: The Configuration Tab
Profile Name
Enter texts in the Profile Name field to identify a new profile. After defining the configurations below,
click the Apply button to establish the profile. To switch between any existing profiles, click the arrow
button at the right of the Profile Name field to open the pull-down menu and then select an intended
one from it.

Note: You will have at least one profile named ANY, which allows a link with an Access Point or a Wireless
LAN PC Card equipped computer at the given time. When you click the Defaults button under the tab, a profile
of the current connection is created.
Network Name
Network Name , also known as SSID (Service Set Identifier), must be unique to distinguish itself as
a particular wireless network, while all wireless points in this network area share the same SSID.
Type the identical SSID in the Network Name field to associate with access points or stations within
the specified wireless LAN. To change the Network Name, highlight the name in the box, edit a new
SSID, and then click Apply to save the changes.
Network Type
Two network types are offered here: Access Point and Peer-to-Peer. Choose the intended type
from the two options. The Access Point mode, which is also known as the Infrastructure mode,
allows you to communicate with a wired network via an access point. If you attempt to operate this
mode, you must indicate the identical Network Name to make a communication with the intended
access point. On the other hand, the Peer-to-Peer mode provides you with the so-called Ad-Hoc
communication, which means each wireless-equipped computers within a group is able to connect
with each other as an independent wireless LAN without the use of an access point. Each station
within this Ad-Hoc network has to define the same Network Name .
Peer-to-Peer Channel
This command is only available while you are operating the Peer-to-Peer mode, the so-called
Ad-Hoc mode. Specify the operating radio frequency channel from the pull-down menu if you are the
creator of the wireless network. If you are the joiner, just configure the SSID and click Apply. Note
that the available channels differ from country to country, and the channel number must be the same
between the entries/stations within the range, so that each can communicate with each other. While
in the Access Point mode, the channel number would be the same as the associated access point.
Thus, there’s no need to manually set up the value.
Transmit Rate
This command allows you to indicate the rate of transferring the data packet from the associated
access point or any nodes within the range. There are four options for you: Auto 1 or 2 Mb, 5.5 Mb,
11 Mb, and Fully Automatic. Specify the rate from the provided options according to the speed of
your wireless network, or you may simply choose Fully Automatic to set the best available rate
according to the received signal quality and the capabilities of the associated access point or station.
The Encryption Tab
Click the Encryption tab to define the encryption settings for a specific profile. It offers you various
options concerning the so-called WEP (Wired Equivalent Privacy) to maintain the secure management

in a wireless LAN environment. See the explanations below for more details, and before making an
activation of any new settings, click Apply. To leave the window, click OK. To undo the new settings,
select the Cancel button.
Note: Choosing the WEP Encryption command from the right-click menu of WLAN PRISM3 IEEE802.11b
tray icon will launch this tab too.
Figure 4.3-4: The Encryption Tab
Encryption (WEP security)
If you choose Disabled from the pull-down list, you will have the wireless LAN USB stick
communicated with all stations within the same networking community without any data encryption.
Otherwise, two key lengths are offered: 64 bit and 128 bit. Specify a preferred one from the two, so
that you may use the identical WEP key to make a communication with the chosen access point.
Create Key Manually
Once you set the Encryption type as 64 bit or 128 bit, you may choose to edit WEP keys manually
or create them via the passphrase of your wireless network. If you choose the Create Key Manually
option, you may directly enter up to 4 WEP keys for use in WEP encryption. To generate the WEP
keys, please define the key entry method as Alphanumeric or Hexadecimal (for hexadecimal
characters, only digits 0-9 and letters A-F are valid). Then edit the texts in the blank fields below,
from Key 1 to Key 4, as the encryption codes. Note that these codes/keys shall be identical between
the wireless nodes within the range and the access point only. Check the table below to find valid
key length of each encryption type:
64 bit 128 bit
Alphanumeric
5 characters 13 characters
Hexadecimal
10 digits 26 digits
M061703V10

Use WEP Key
Indicate which WEP key you intend to apply to activate the WEP encryption from the pull-down
menu. Make sure that the intended access point on the wireless network shares the same keys. By
default, Key 1 will be used.
Create Keys with Passphrase
Choose this command when the associated wireless network uses a passphrase to create WEP
keys. Enter the passphrase sting in the Passphrase filed to generate four encryption keys in the
Key fields above. Note that only letters A-F are valid for the Passphrase feature.
After finish configuring the Encryption features, remember to click the Apply button to initiate the new
settings.
