Advanced Wireless Configuration for Access Point Groups

NETGEAR recommends using the default settings as they are to configure your access
points unless you have specific reasons to change them. You can configure wireless settings

performance, but some legacy devices can operate only on either 20 MHz or 40
MHz.
interval improves performance, but some legacy devices can operate only with a long
guard interval.
The transmission mechanism (CSMA/CA or CSMA/CD) for the packets. If the packet
size is equal to or less than this threshold, then the data frame is transmitted
immediately. However, if the packet size is larger than the specified value, then the
transmitting station must send out an Request to Send Threshold (RTS) packet to the
receiving station, and then must wait for the receiving station to send back a Clear to
Send (CTS) packet before sending the actual packet data.
The maximum packet size that used for fragmentation of data packets. Packets
larger than the specified fragmentation length are broken up into smaller packets
before being transmitted. The fragmentation length must be an even number.
The time interval for each beacon transmission that allows the access point to
synchronize the wireless network.
The length that defines the maximum length of Aggregated MAC Protocol Data Unit
(AMPDU) packets. Larger aggregation lengths might sometimes lead to better
network performance. Aggregation is a mechanism used to achieve higher
throughput.
Allow the aggregation of several MAC frames into a single large frame to achieve
higher throughput. Enabling AMPDU can sometimes lead to better network
performance.
Enable the Reduced Interframe Space (RIFS) option to allow transmission of
successive frames at different transmit powers. Enabling RIFS can lead to better
network performance.
Enter the DTIM or the data beacon rate that you want to use. This sets the message
period of the beacon delivery traffic indication in multiples of beacon intervals.
A long transmit preamble can provide a more reliable connection or a slightly longer
range. A short transmit preamble gives better performance. The Auto setting
automatically handles both long and short preambles. The default is Auto.
