RTS Threshold

Defines the size of packets that the station uses for RTS/CTS handshake
boundary. Setting the minimum size packet too small causes RTS packets
to be sent more often, adding excessive overhead to the network and de-
creasing network utilization. However, the more often RTS packets are
sent, the more transmission collisions can be avoided. RTS threshold ranges
from 0 to 2346 in 64 steps.

Fragmentation Threshold

Define the number of bytes used for fragmentation boundary. If the length
of the data unit exceedsthis parameter , it will be divided into smaller frag-
ments for transmission. Each of the fragments is sent independently. If
there is a significant interference present, set the fragment size smaller.
Otherwise,set the fragment size lar ger. Because send multiple frames lead
to overhead on the network.Fragmentation  Threshold ranged from 256 to
2432 steps 128.

3.4.6 Config - Advanced Tab

Advanced tab provides some additional settings for the ASUS SpaceLink
PC Card. The “Advanced” tab is hidden until you click Advanced on the
