Configure Wireless Settings

Beacon Interval

The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the device to synchronize the wireless network.

(Default: 100 msec, Range: 20-1000)

DTIM Interval

The Delivery Traffic Indication Message (DTIM) indicates the interval between Broadcasts/Multicast transmissions. DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the device 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.

(Default: 1, Range: 1-255)

Fragmentation Threshold

The fragmentation threshold 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

The RTS Threshold determines at what packet size beyond which the ready to send/clear to send (RTS/CTS) mechanism is invoked. 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 device 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.

Wireless > WDS Settings

The Wireless Distribution System (WDS) Settings page allows you to expand the coverage of your wireless network by deploying signal repeaters. Make sure the channel settings are the same for all WDS enabled devices.
