4.4.1.2 Advanced Settings
In the Wireless Settings page, click Advanced settings , the page shown in
the following figure appears.

Multicast Rate: Select the multicast transmission rate for the network.
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. The default value is
Auto .
 Fragmentation Threshold: 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 reducing networking
performance.

RTS Threshold: This value should remain at its default setting of
2347.Should you encounter inconsistent data flow, only minor reductions
are recommended. Should 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. 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. The RTS Threshold value should remain at its default
value of 2347.

DTIM Interval: (Delivery Traffic Indication Message) Enter a value
between 1 and 255 for the Delivery Traffic Indication Message (DTIM.) A
DTIM is a countdown informing clients of the next window for listening to
broadcast and multicast messages.

Beacon Interval: 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. A beacon interval is a period of time (sent with the
beacon) before sending the beacon again. The beacon interval may be
adjusted in milliseconds (ms). Default (100) is recommended.

Global Max Clients: Specifies maximum wireless client stations to be
enble to link with AP. Once the clients exceed the max vlaue, all other
clients will be refused.
