users will see different settings.
Client Timeout : If the access point is not able to
communicate with the client it will disconnect it after this timeout (in seconds).
TX Power : Normally the wireless transmitter operates at 100% power. In some circumstances, however, there
might be a need to isolate specific frequencies to a smaller area. By reducing the power of the radio, you can
prevent transmissions from reaching beyond your corporate/home office or designated wireless area.
RTS Threshold : When an excessive number of wireless packet collisions are occurring, wireless performance
can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless
transmitter will begin to send RTS frames (and wait for CTS) when data frame size in bytes is greater than the
RTS Threshold. This setting should remain at its default value.
Fragmentation Threshold : Wireless frames can be divided into smaller units (fragments) to improve
performance in the presence of RF interference and at the limits of RF coverage. Fragmentation will occur
when frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at its default
value. Setting the Fragmentation value too low may result in poor performance.
DTIM : A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast
messages. When the wireless router has buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the
broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255.
Beacon : Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon
Period value between 20 and 1000 milliseconds.
Short Slot : Slot Time is the period wireless clients use in determining if the channel is free for transmission.
Enabling this value allows clients that can utilize a shorter time to do so. Disabling this option forces all
clients to use a longer backoff check and thus may reduce network throughput while reducing the number of
transmission collisions.
