default value of 2 indicates that the access point will save all broadcast/multicast frames
for the Basic Service Set (BSS) and forward them after every second beacon. Using
smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner,
causing stations in Power Save mode to wake up more often and drain power faster.
Using higher DTIM values reduces the power used by stations in Power Save mode, but
delays the transmission of broadcast/multicast frames. (Range: 1-255 beacons; Default:
1 beacon)
• Fragment Threshold – Configures the minimum packet size that can be fragmented
when passing through the access point. 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 speed up the retransmission of smaller frames. However, it
is more efficient to set the fragment size larger if very little or no interference is present
because it requires overhead to send multiple frames. (Range: 256-2346 bytes; Default:
2346 bytes)
• RTS Threshold – Sets the packet size threshold at which a Request to Send (RTS)
signal must be sent to a receiving station prior to the sending station starting
communications. The access point sends RTS frames to a receiving station to negotiate
the sending of a data frame. After receiving an RTS frame, the station sends a CTS
(clear to send) frame to notify the sending station that it can start sending data. If the
RTS threshold is set to 0, the access point always sends RTS signals. If set to 2347, the
access point never sends RTS signals. If set to any other value, and the packet size
equals or exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send)
mechanism will be enabled. The access points contending for the medium may not be
aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.”
(Range: 0-2347 bytes)
• TX Power – Adjusts the power of the radio signals transmitted from the access point.
The higher the transmission power, the farther the transmission range. Power selection
is not just a trade off between coverage area and maximum supported clients. You also
have to ensure that high-power signals do not interfere with the operation of other radio
devices in the service area.
• Short Preamble – Enables the length of the signal preamble that is used at the start of
a data transmission. (Default: Disable)
• Short Slot – Sets the basic unit of time the Multimedia Router’s uses for calculating
waiting times before data is transmitted. Enabling a short slot time can increase data
throughput on the Multimedia Router, but requires that all clients can support a short slot
time (that is, 802.11g-compliant clients must support a short slot time). (Default: Enable)
• Tx Burst – Enables data transmission bursting to boost throughput for high data
transmissions. (Default: Enable)
• Pkt_aggregation – Enables grouping together of some packets and sending them
together to boost bandwidth. (Default: Enable)
