Config - Advanced
Click Advanced link on Config-Basic page
to show this tab. This tab allows you to set
up additional parameters for the wireless
Adapter. We recommend using the default
values for all items in this window.
RTS Threshold (0-247)
The RTS/CTS (Request to Send/Clear to Send) function is used to minimize
collisions among wireless stations. When RTS/CTS is enabled, the router
refrains from sending a data frame until another RTS/CTS handshake is
completed. Enable RTS/CTS by setting a specific packet size threshold. The
default value (2347) is recommended.
Fragmentation Threshold (26-246)
Fragmentation is used to divide 802.11 frames into smaller pieces (fragments)
that are sent separately to the destination. Enable fragmentation by setting
a specific packet size threshold. If there is an excessive number of collisions
on the WLAN, experiment with different fragmentation values to increase the
reliability of frame transmissions. The default value (2346) is recommended for
normal use.

default values do not have to be changed.
