The Advance configuration provides advance function about network environment if you want 

to know more detail of the Advanced configuration. Please consults administrator. 

The WLAN Utility also offers the advanced configuration for user to set the 802.11g Wireless 

LAN PCI Card under certain network environment. These advanced options include Power 

Management, RTS and Fragmentation Threshold. To enable the advanced configuration, go to 

the Configuration tab and click the Advance button. 

 

The Power Save option is designed to conserve battery life of you computer. When Power Save 

is enabled, your 802.11g Wireless LAN PCI Card will go into sleep mode to minimize power 

consumption. 

Warning: When power saving mode is enabled, the Access Points you use need 
to support power saving as well so that the communication can be established. 

RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. “Hidden 

Node” is a situation in which two stations are within range of the same Access Point, but are not 

within range of each other. The following figure illustrates an example of the “Hidden Node” 

problem. Both stations (STA) are within range of the Access Point, however, they cannot hear 

each other. Therefore, they are hidden nodes for each other. When a station starts data 

transmission with the Access Point, it might not notice that the other station is already using the 

wireless medium. When these two stations send data at the same time, they might collide when 

arriving simultaneously at the Access Point. The collision will most certainly result in a loss of 

messages for both stations.
