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.

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.
