Chapter 5: Configuring the Wireless-N Home Router
The Wireless Tab - Advanced Wireless Settings
Wireless-N Home Router
boosts the Router’s ability to catch all Wireless-N and Wireless-G transmissions but will severely decrease
performance.
Beacon Interval. Enter a value between 20-1000 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. The default value is 100.
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, 2346, 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. In most cases, keep its default value of 2346.
