N Transmission Rate The rate of data transmission should be set depending
on the speed of your Wireless-N networking.
You can select from a range of transmission speeds, or
you can select Auto to have the CVR100W
automatically use the fastest possible data rate and
enable the Auto-Fallback feature.
Auto-Fallback will negotiate the best possible
connection speed between the CVR100W and a
wireless client. The default is Auto.
CTS Protection Mode The CVR100W 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 CVR100W in an
environment with heavy 802.11b traffic.
This function boosts the CVR100W’s 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 CVR100W to synchronize the wireless network.
Enter a value between 40 and 3500 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 CVR100W 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.
