Open System network.

 

 

 

Wired Equivalent Privacy (WEP) data encryption is

 

 

 

used when the wireless devices are configured to

 

 

 

operate in Shared Key authentication mode.

 

 

 

If the Access Point is using Open System, then the

 

 

 

wireless adapter will need to be set to the same

 

 

 

authentication mode.

 

 

 

Shared Key is used when both the sender and the

 

 

 

recipient share a secret key.

 

 

 

Select Auto for the network adapter to select the

 

 

 

Authentication mode automatically depending on the

 

 

 

Access Point Authentication mode.

 

 

 

 

 

 

Fragment Threshold

Fragmentation mechanism is used for improving

 

 

 

the efficiency when high traffic flows along in the

 

 

 

wireless network. If your 802.11g Wireless LAN

 

 

 

PC Card often transmit large files in wireless

 

 

 

network, you can enter new Fragment Threshold

 

 

 

value to split the packet. The value can be set

 

 

 

from 256 to 2346. The default value is 2346.

 

 

RTS Threshold

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. 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.

 

 

 

Thus, the RTS Threshold mechanism provides a

 

 

 

solution to prevent data collisions. When you enable

 

 

 

RTS Threshold on a suspect “hidden station”, this

 

 

 

station and its Access Point will use a Request to

 

 

 

Send (RTS). The station will send an RTS to the

 

 

 

Access Point, informing that it is going to transmit the
