DTIM Interval
The interval for sending 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 WRP400 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. Enter a value between 1 and 255.
Default: 1
RTS Threshold
The WRP400 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. If
you encounter inconsistent data flow, only minor
reduction of the default value, 2347, is
recommended. If a network packet is smaller
than the preset RTS threshold size, the RTS/
CTS mechanism will not be enabled.
Default: 2347
