radio transmission, such as metal objects, electronic devices, cordless telephones, and 
microwave oven.   

 

If necessary, move your notebook computer a few inches to find a better signal. 
Environmental condition varies with users’ location, a difference of one or two inches 
can mean the difference between a strong and a weak signal. Even a slight change in 
PC orientation can improve a wireless connection.   

 

If you have installed the Configuration Utility, you may use the Signal Strength display 
in the Link Info to determine the best location and orientation for a wireless network 
connection.

 

 

LED Indication 

The yellow LED of Wireless LAN PC Card performs identical functions when indicating the 
operational status of the card. 
 

Advanced Configuration 

 

Configuration 

Mode (Network Mode) 

1. 

Ad-Hoc:

 The Ad-Hoc network is also known as a peer-to-peer network. An Ad-Hoc 

networking does not need Access Point. Instead, the Ad-Hoc network is a loose 
association of wireless computers that can communicate with each other using 
Wireless LAN PC Card in Ad-Hoc Mode 

2. 

Infrastructure:

 In a wireless infrastructure network, wireless stations communicate 

with an Access Point to connect to a wired network. An infrastructure network also can 
consist of multiple Access Points. This can extend the coverage area of wireless 
network. In this configuration, the wireless network consists of cells. Each cell is a 
single Access Point that has different frequency channel to prevent from interfering 
each other. A wireless station can move from one Access Point to next without losing 
the network connection. 

 

SSID 

The SSID is the name of wireless network for Ad-Hoc or Infrastructure mode. To add a 
Wireless LAN PC Card to an existing wireless network, configure SSID to match the name 
of the wireless network 

Tx Rate 

The Fixed 1, 2, 5.5, 11Mb/s or Fully Auto transmit rates can be selected for Wireless LAN
