Fragmentation Length
Specify the maximum size in byte for a packet before data is fragmented into multiple packets.
Setting it too low may result in poor network performance. Leave it at its default of 2346 is
recommended.
Beacon Interval
Specify the frequency interval to broadcast packets. Enter a value between 20 and 1024.
DTIM Interval
DTIM, which stands for Delivery Traffic Indication Message, is contained in the data packets. It is
for enhancing the wireless transmission efficiency. The default is set to 1. Enter a value between
1 and 255.
Preamble Type
It defines some details on the 802.11 physical layer. "Long" and "Auto" are available.
IGMP Snooping
Available in AP/Router mode, IGMP snooping is the process of listening to IGMP network traffic.
By enabling IGMP snooping, the AP will listen to IGMP membership reports, queries and leave
messages to identify the ports that are members of multicast groups. Multicast traffic will only be
forwarded to ports identified as members of the specific multicast group or groups.
RIFS
RIFS (Reduced Interframe Spacing) is a means of reducing overhead and thereby increasing
network efficiency.
Link Integration
Available under AP/Bridge/AP repeater mode, it monitors the connection on the Ethernet port by
checking "Enabled". It can inform the associating wireless clients as soon as the disconnection
occurs.
TDM Coordination
Stands for "Time-Division Multiplexing Technique", this resource reservation control mechanisms
can avoid packet collisions and send the packets much more efficiently allowing for higher
effective throughput rates.
recommended to enable TDM coordination when there are multiple CPEs needed to connect to
the AP in your application.
