In the  following section, you will be guided through the basic 3-step workflows of 
configuring your network via the prompted attached configuration tool. Please read 
carefully to start the task. 
Step 1: Advanced Tab 
Firstly, choose this tab to define the network standard you wish to use. 
a) On the Advanced tab, choose Configuration Profile from Property. 
b) Define which network standard you intend to operate from the Value 
drop-down menu.  WiFi Sepc is the default value. To use both 802.11b and 
802.11g network standards, please choose Mixed. 
Step 2: Configuration Tab 
Click this tab to edit different profiles for different network configurations.   
a) Specify the network types as Access Point and Peer-to-Peer from the 
Network Type area. 
b) Type the identical SSID in the Network Name field to associate with access 
points or stations within the specified wireless LAN. 
c) Click Apply to establish the connection.   
d) If you wish to create a new profile for the current association, please enter 
texts in the  Profile Name field and then click  Save As to identify a new 
profile. You may switch between any existing profiles by clicking the arrow 
button at the right of the Profile Name field to open the pull-down menu and 

 13
then select an intended one from it. 
Tips: To obtain the general information on the status of currently connected 
entry, click the Status tab.   
Step 3: Security Tab 
To maintain the secure management in a wireless LAN environment, click the 
Security tab to define the encryption settings for a specific profile. This tab offers you 
various options concerning the so-called WEP (Wired Equivalent Privacy). 
a) Define the Authentication Type as WEP. 
b) Specify the key length from the two offered options: 64 bit or 128 bit from 
the Encryption (WEP security) drop-down menu. 
c) Now you  may choose to edit WEP keys manually or create them via the 
passphrase of your wireless network. If you choose the Create Keys 
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).   
d) 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.   
e) Indicate which WEP key you intend to apply to activate the WEP encryption 
from the Use WEP Key drop-down menu. Make sure that the intended 
access point on the wireless network shares the same keys. 

 14
f) When the associated wireless network uses a passphrase to create WEP keys, 
you may select Create Keys with Passphrase, and then enter the passphrase 
string 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. 
g) Indicate the Authentication Mode as Open, Shared, or AutoSwitch. Note 
that the value shall be corresponding to the currently associated access point. 
The Open option allows any station in the WLAN to receive and transmit 
data via the access point. The Shared option allows only the stations that use 
identical keys to associate with the access point. While choosing AutoSwitch, 
any station can associate with the access point either with or without 
encryption keys. 
h) Click Apply to active all the settings when you are done. 
Tips: To obtain the general information on the status of currently connected entry, 
click the Status tab. 
Other Tabs 
Besides the three tabs mentioned above, there are other six tabs that also provide you 
versatile functions. Please read the explanations below to learn more about each tab. 
The General Tab 
This tab reveals brief information on the 802.11 g/b WLAN USB Stick device itself. 

 15
The Status Tab 
Click the Status tab to appear the following display.   
From the window, the general information on the status of currently connected entry 
is presented. You may want to click the  Rescan  button to reinitiate the scanning 
process and update the status. Later the result of scanning will be renewed and 
displayed in the window. If you wish to stop the  networking connection, click the 
Disable Radio button to stop scanning. However, if you are already in the disabled 
radio mode, you will find the Enable Radio button here instead. Click Enable Radio 

 16
to regain the link then. 
State 
Here displays the MAC Address of the current associated entry, which could be a 
connected access point in the Access Point mode or computers joining in the 
Peer-to-Peer network. 
Current Tx Rate 
This feature indicates the transmission rate of the current connection. 
Current Channel 
Here reveals the current channel operated in the wireless network. Note that the 
channel number differs as the radio scans any available channels in the Peer-to-Peer 
mode. 
Throughout (bytes/sec) 
This feature indicates the rates of transmitting (Tx) and receiving (Rx) data of your 
WLAN USB 802.11 g/b WLAN USB Stick within a short period of time; thus, the 
values vary on a time basis. 
Link Quality 
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 Peer-to-Peer 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 Access 
Point mode. They are  inapplicable in the  Peer-to-Peer mode since data will be 
transferred from many different computers. 
The IBSS Tab 
If you, as a creator of the wireless network, are communicating with other stations via 
the IBSS mode to form Peer-to-Peer networks, click the  IBSS (Independent  Basic 
Service Set) tab to specify an operating radio frequency channel from the pull-down 
list under the IBSS Channel Selection section. 

 17
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. 
To let the new configuration take effect, please choose Apply. 
On the other hand, while in the Access Point mode, you will find the channel number 
is the same as the associated access point. Thus, there’s no need to manually set the 
value. 
The Domain Tab 
While in the 2.4GHz range, the network operation may differ from country to country, 
or domain to domain. This is because the 802.11d protocol was established. To have 
the operation normally processed, choose the Domain tab to change relevant settings. 

 18
802.11d Support 
802.11d Support lets you operate multi-country roaming. To automatically adjust 
regulatory domain  while operating network in  different countries, choose either 
Strict or Flexible according to your need. If you choose None, the task will be 
terminated. 
Countries/Domains 
Define  the regulatory domain from the drop-down menu of this command 
according to the country you are located in. More detailed information about the 
defined country/domain will be listed below afterwards. 
When you are done, remember to click Apply to let the new settings take effect. 
The About Tab 
This tab reveals general information on your 802.11 g/b WLAN USB Stick, including 
the following items: 

 19
Network Driver 
Displays the current version and released date of the 802.11 g/b WLAN USB 
Stick’s driver. 
Configuration Utility

Control) address of your  wireless card. It is consisted of 12-digit hexadecimal 
numbers (48 bits in length)  to identify your computer's physical address on the 
local area network. 
The Driver Tab 
This tab provides you various commands used on the 802.11 g/b WLAN USB Stick’s 
driver.
