Beacon
Interval
A beacon is a packet sent by a wireless access point to synchronize
wireless devices. The beacon interval value indicates the frequency interval
of the beacon. Increasing the beacon interval reduces the number of
beacons and the overhead associated with them. The default value is
100
,
but
50
is recommended when reception is poor.
DTIM
Interval
The value specifies the maximum size for a packet before data is
fragmented into multiple packets. The value should remain at the default
2346
(the range is 256 - 2346 bytes). If you experience a high packet error
rate, you may slightly increase the value. Setting the value too low may
result in poor network performance. Only minor modifications of this value
are recommended.

Threshold
The RTS (Request to Send) Threshold is the amount of time a wireless
device, attempting to send, will wait for a recipient to acknowledge that it is
ready. Normally, the AP sends a RTS frame to a station and negotiates the
sending of data. After receiving the RTS, the station responds with a CTS
(Clear to Send) frame to acknowledge the right to begin transmission. To
ensure communication, the maximum value should be used, which is the
