Description
Transmit power Allows the user to adjust the transmit power of the router. A high transmit power allows a greater area range of accessibility to the router. When
multiple overlapping access points are present, it may be desirable to reduce transmission power.
Beacon Interval Beacons are emitted from the router in order to synchronize the wireless network. You may set the Beacon Interval range between 20-100
microseconds per beacon sent. The default is 100.
RTS Threshold The RTS (Request to Send) Threshold controls the size of data packets issued to a RTS packet. A lower level will send packets more frequently
which may consume a great amount of the available bandwidth. A high threshold will allow the router to recover from interference or collisions
which is more prevalent in a network with high traffic or high electromagnetic interference. The default setting is 2346.
Fragmentation The fragmentation threshold will determine if packets are to be fragmented. Packets over the 2346 byte limit will be fragmented before
transmission. 2346 is the default setting.
DTIM Period DTIM (Delivery Traffic Indication Message) Period is a countdown informing clients of the next menu for listening to broadcast and multicast
messages. The default setting is 1.
Preamble Type Long Preamble should be used where 802.11b clients are present.
CTS Mode Clear to Send mode should only be used when wireless clients are close enough to each other to “hear“ or detect the presence of ther other clients.
The Auto option will use CTS mode only when associating clients are in close proximity to each other.
802.11g Only Mode The access point can be forced to associate with exclusively 802.11g devices.
Fragmentation The fragmentation threshold will determine if packets are to be fragmented. Packets over the 2346 byte limit will be fragmented before
transmission. 2346 is the default setting.
