Wireless-G Broadband Router with RangeBooster
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode's default setting is Auto. The Router will
automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and
are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the
Router's ability to catch all Wireless-G transmissions but will severely decrease performance.
Beacon Interval. 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 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. The default value is 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. The default value is 2346.
