Section 3 - Configuration
ADVANCED SETTINGS
Most about wireless setting was referred in WIRELESS chapter, if you
need to change the other default setting,
The default value of Multicast Rate is Auto. The rate of data
transmission should be set depending on the speed of your wireless
network. You can select from a range of transmission speeds, or you can
select Auto to have the Router automatically use the fastest possible data
rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the
best possible connection speed between the Router and a wireless client.
Packets that are larger than this threshold are fragmented into multiple
packets. Try to increase the Fragmentation Threshold if you encounter
high packet error rates. Do not set the threshold too low, since this can
result in reduced networking performance.
This value of RTS Threshold should remain at its default setting as
2347.Should you encounter inconsistent data flow, only minor reductions
are recommended. If a network packet is smaller than the preset RTS
threshold size, the RTS/CTS mechanism will not be enabled. The Router
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.
Input the value 1 to 255 into the DTIM Interval. A DTIM (Delivery Traffic
Indication Message) is a countdown informing clients of the next window
for listening to broadcast and multicast messages.
A beacon is a packet of information that is sent from a connected device
to all other devices where it announces its availability and readiness.
Beacon Interval is a period of time (sent with the beacon) before sending
the beacon again. The beacon interval may be adjusted in milliseconds
