CTS Protection
Mode
The Cisco RV215W will automatically use CTS (Clear-
To-Send) Protection Mode when your Wireless-N and
Wireless-G devices are experiencing severe problems
and are not able to transmit to the Cisco RV215W in an
environment with heavy 802.11b traffic.
This function boosts the Cisco RV215W ability to catch
all Wireless-N and Wireless-G transmissions but will
severely decrease performance. The default is Auto.
Beacon Interval The Beacon Interval value indicates the frequency
interval of the beacon. A beacon is a packet broadcast
by the Cisco RV215W to synchronize the wireless
network.
Enter a value between 40 and 3,500 milliseconds. The
default value is 100.
DTIM Interval 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 RV215W 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.
Fragmentation
Threshold
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.
