Identifies fragment size in bytes. This value should
remain at its default setting of 2345. It specifies the
maximum size for a packet before data is fragmented
into multiple packets. If you experience a high packet
error rate, you may slightly increase the fragmentation
threshold. Setting the fragmentation threshold too low
may result in poor network performance. Only minor
modifications of this value are recommended.
Indicates the interval of the delivery traffic indication
message (DTIM) in milliseconds. A DTIM field is a
countdown field informing clients of the next window
for listening to broadcast and multicast messages.
When the wireless port has buffered broadcast or
multicast messages for associated clients, it sends the
next DTIM with a DTIM Interval value. Its clients hear
the beacons and awaken to receive the broadcast and
multicast messages.
Identifies request to send (RTS) threshold in bytes.
Should you encounter inconsistent data flow, only
minor modifications are recommended. If a network
packet is smaller than the preset RTS threshold size,
the RTS and clear to send (CTS) mechanism is not
enabled. The wireless port sends RTS frames to a
particular receiving station and negotiates the sending
of a data frame. After receiving an RTS, the wireless
station responds with a CTS frame to acknowledge
the right to begin transmission.
Gives the size of the packet preamble
Specifies the maximum number of clients allowed to
connect simultaneously.
Indicates the number of transmission attempts of a
frame, the length of which is less than or equal to
rts-threshold, made before a failure condition is
indicated.
Indicates the number of transmission attempts of a
frame, the length of which is greater than
rts-threshold, made before a failure condition is
indicated.
