4.5.2 WIRELESS - Configuration
The Configuration page describes how to configure the wireless features of your 4 Ports 11g Wireless
ADSL2/2+ Router.
Beacon Period:
Enter a value between 1 ~ 65535 milliseconds. The Beacon Interval value
indicates the frequency interval of the beacon. A beacon is a packet broadcast by the 4 Ports 11g
Wireless ADSL2/2+ Router to synchronize the wireless network. The default value is 200.
DTIM Period:
This value, between 1 ~ 65535, 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 4 Ports 11g Wireless ADSL2/2+
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 2.
RTS Threshold:
The range is 0 ~ 3000 bytes. If a network packet is smaller than the preset RTS
threshold size, the RTS/CTS mechanism will not be enabled. The 4 Ports 11g Wireless ADSL2/2+
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. This default setting is 2347.
However, when 4x is enabled on the setup page, the RTS threshold value changes to 4096.
Frag Threshold:
The Fragmentation Threshold. The range is 256 ~ 2346 bytes. It 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
modifications of this value are recommended. This default setting is 2346. However, when 4x is
enabled on the setup page, the fragmentation threshold value changes to 4096.
