Go to Wireless | Advanced Settings in order to change the
Fragmentation and RTS thresholds. (Note: It is recommended to
leave these values at their default settings.)
RTS Threshold: Set the RTS (Request to Send) frame length. You
may configure the access point to initiate an RTS frame. If the
packet size is smaller than the preset RTS threshold size, the
RTS/CTS mechanism will NOT be enabled.
The access point sends Request to Send (RTS) frames to a
particular receiving station to negotiate the sending of a data
frame. After receiving an RTS, the station sends a CTS (Clear to
Send) frame to acknowledge the right of the sending station to
send data frames. The access points contending for the medium
may not be aware of each other. The RTS/CTS mechanism can
solve this “Hidden Node Problem.”
Fragmentation Threshold: If the packet size is smaller than the
preset Fragment size, the packet will not be segmented.
Fragmentation of the PDUs (Package Data Unit) can increase the
reliability of transmissions because it increases the probability of
a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments.
This will enable the retransmission of smaller frames much faster.
