E. Security 
E1: What is WEP? 
WEP stands for Wired Equivalent Privacy, a security service, used to 
prevent the unauthorized access to your wireless network. 
E2: How many WEP security service modes does my Wireless LAN 
support? 
WEP stands for Wired Equivalent Privacy that is the security service for 
the Wireless Network. There are three WEP security service modes 
available for “IEEE 802.11b WLAN Adaptor” formed Wireless Net- work. 
The first is “Disable” which will disable the WEP security service; the 
second is “64bit” which will support 5 bytes Hexadecimal value WEP 
security service; the third is “128bit” which will support 13 bytes 
Hexadecimal value WEP security service. 
E3: How do I set the WEP security service? 
Please click Start> Settings> System> Wireless LAN Utility> Advanced to 
view Advanced page where you can set the WEP security service. Please 
choose the proper WEP Key Mode, WEP KeyID and WEP Key value for 
the Wireless Network. 
The WEP Mode, WEP KeyID and WEP Key value must be exactly the same as your Wireless Network’s to enable the connection. Example of 
setting the WEP: 
You can choose: 
1. WEP Mode “64bit”, KeyID “1” and Key “1234567890”, or 
2. WEP Mode “128bit”, KeyID “1” and Key 
“12345678901234567890123456”, or  
3. WEP Mode “Disable” for connection 
F. Performance 
F1: Will IEEE802.11b WLAN Adaptor work in the environment where 
Bluetooth network is employed? 
Yes, IEEE802.11b WLAN Adaptor can coexist with Bluetooth 
environment. 
F2: How far is the working range of IEEE802.11b WLAN Adaptor? 
It depends on the data transmission rate and the condition of the 
environments. The higher the data rate, the smaller the range it could 
cover. At 11 Mbps, the adaptor can go up to 300 meter in an outdoor 
environment; however, in an indoor environment, it can only go up to 100 
meter. Because of the ceilings, higher RF interference, interior walls and 
reflected signals, indoor range is usually shorter than outdoor range.

F3: How does the data transmission rate work? 
IEEE802.11b WLAN Adaptor allows you to choose one of the six data rate 
options: Fixed 1Mbps, Fixed 2Mbps, Fixed 5.5Mbps, Fixed 11 Mbps, 
Auto Select 1 or 2 Mbps, and Fully Auto. 
The farther the distance between two communicating devices, the slower 
the data rate should be used. Basically, with slower data rate, the data 
delivery will be more reliable. If you don’t know which data rate should be 
used, simply choose “Fully Auto”, and the data rate will automatically 
step down from 11 Mbps, 5.5 Mbps, 2 Mbps, to 1 Mbps if you move 
farther your Pocket PC away from the Access Point or other connected 
mobile device. 
F4: The Wireless LAN uses lots of power. What should I do to save 
power? 
1 Please turn off the Wireless Communication Switch if you are not 
using the Wireless Network currently, or 
2 You can click the “Radio Off” button on Start > Settings > System > 
Wireless LAN Utility > Config page to temperately disable the RF 
function , or 
3 You can click Start > Settings > System > Wireless LAN Utility > 
Advanced to get into Advanced Page and tick the “Enable Power 
Saving Mode” to enter the Power Saving Mode. 
1.  Turn off the Wireless Communication Switch will cause the disconnection of the Wireless Network, please make sure to close all 
the Wireless Connection before you execute this function. 
2.  “Radio Off” function will cause the disconnection of the Wire- less Network , please make sure to close all the Wireless Connection 
before you execute this function. 
3.  Enable “Power Saving Mode” will keep the connectivity but will lower down the average throughput due to longer connection period for the 
Wireless Network. 
4.  If you are in 802.11 Ad Hoc Mode, you are not allowed to en- able “Power Saving Mode”, because Ad Hoc Mode doesn’t support this 
function. 
F5: How do I make sure that the Wireless LAN SW has been installed 
successfully and that Wireless LAN already work properly? 
1 Please check if the “IEEE 802.11b WLAN Adaptor” already exist in 
Start > Settings > Connections > Network Adaptors; if not, the 
Wireless LAN Driver is not Installed successfully. 
2 Please check if the Wireless LAN Utility already exist and could be 
opened successfully by simply click Start > Settings > System > 
Wireless LAN Utility. 
3 Click Start > Settings > System >  Wireless LAN Utility > Link to check 
the current Link information in the Link Page.
