received. Therefore, in a WLAN where there is high error rate, you can decrease the
fragment threshold to increase frame transmission reliability.
Beacon interval (time unit 100-1000, default is 100): interval for sending beacon frames.
Beacon frames are transmitted at a regular interval to allow mobile clients to join the
network. Beacon frames are used for a client to identify nearby APs or network control
devices.
Request to send (RTS) threshold length. If a frame is larger than this value, the RTS
mechanism will be used. RTS is used to avoid data sending collisions in a WLAN. You
need to set a rational value: A small value causes RTS packets to be sent more often, thus
consuming more of the available bandwidth. However, the more often RTS packets are
sent, the quicker the system can recover from interference or collisions.
DTIM Period (1-255, default is 1) Number of beacon intervals between delivery traffic
indication message (DTIM) transmissions. The AP sends buffered broadcast/multicast
frames when the DTIM counter reaches 0.
Long Retry Threshold (1-15, default is 4) Number of retransmission attempts for frames
larger than the RTS threshold.
Short Retry Threshold (1-15, default is7) Number of retransmission attempts for frames
smaller than the RTS threshold if no acknowledgment is received for it.

Caution:
Only if the wireless radio mode contains 11n, you can configure the 11n configuration parameter.
