ASUS WL-530g Manuel D’Utilisation

Fragmentation Threshold (256~2346) – 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.

RTS Threshold (0~2347) – 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.

DTIM Interval (1~255) – DTIM (Delivery Traffic Indication Message) is
a wireless message used to inform clients in Power Saving Mode when the
system should wake up to receive broadcast and multicast messages. Type
the time interval in which the system will broadcast a DTIM for clients in
Power Saving Mode. The default value (3) is recommended.

Beacon Interval (1~65535)  – This field indicates the time interval in
milliseconds that a system broadcast packet, or beacon, is sent to synchronize
the wireless network. The default value (100 milliseconds) is recommended.
