Advanced features allows you to change advanced configuration settings: Fragmentation
Threshold
and RTS Threshold.
Fragmentation Threshold: The fragmentation threshold, which is specified in bytes,
determines whether packets will be fragmented and at what size. On an 802.11 wireless LAN,
packets exceed the fragmentation threshold are fragmented, i.e., split into, smaller units
suitable for the circuit size. Packets smaller than the specified fragmentation threshold value
are not fragmented.
RTS Threshold:. When set (in bytes), it specifies the packet size beyond which the Wireless
LAN Card invokes its RTS/CTS mechanism. Packets that exceed the specified RTS threshold
trigger the RTS/CTS mechanism. The NIC transmits smaller packets without using RTS/CTS.
Changing the Fragmentation/RTS Threshold
By default, the Fragmentation and RTS Threshold are disabled. To change the
Fragmentation/RTS Threshold parameters, move the slide bar with your mouse and then
use the right and left arrow keys of your keyboard to select an exact number in bytes.
