environment with heavy 802.11b traffic, then enable CTS Protection Mode. This function boosts the Router's
ability to catch all Wireless-G transmissions but will significantly decrease performance.
Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. The Beacon
Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to
synchronize the wireless network.
DTIM Interval. This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message
(DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and
multicast messages. When the Router 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. The default value is 1.
Fragmentation Threshold. This value 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
reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (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 Clear to Send (CTS)
frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default
value of 2347.

beacon interval: data transmitted
on your wireless network that
keeps the network synchronized.

packets that can increase wireless
efficiency.
fragmentation: breaking a packet
into smaller units when
transmitting over a network
medium that cannot support the
original size of the packet.
