DTIM Interval

Click Save.
This value, between 1 and 255, 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 Cisco RV110W 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.
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. In most cases, it
should remain at its default value of 2346.
If you encounter inconsistent data flow, enter only minor
reductions. The default value of 2347 is recommended.
If a network packet is smaller than the preset Request to
Send (RTS) threshold size, the RTS/Clear to Send (CTS)
mechanism will not be enabled. The Services Ready
Platform sends 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 CTS frame to acknowledge the right to begin
transmission.
