Description
data packets. Packets that are larger than the specified fragmentation
length are broken up into smaller packets before being transmitted.
The fragmentation length needs to be an even number. The default
setting is 2346.
Enter the interval between 100 ms and 1000 ms for each beacon
transmission, which allows the wireless access point to synchronize
the wireless network. The default setting is 100.
Enter the maximum length of aggregated MAC protocol data unit
(A-MPDU) packets. Larger aggregation lengths could lead to better
network performance. Aggregation is a mechanism used to achieve
higher throughput. The default setting is 65535.
Select the Enable radio button to allow the aggregation of several MAC
frames into a single large frame to achieve higher throughput. Enabling
the aggregated MAC protocol data unit (A-MPDU) could lead to better
network performance. By default, the Enable radio button is selected.
Select the Enable radio button to allow transmission of successive
frames at different transmit powers. Enabling reduced interframe space
(RIFS) could lead to better network performance. By default, the
Disable radio button is selected.
Enter the delivery traffic indication message (DTIM) interval, also
referred to as the data beacon rate, which indicates the beacon
delivery traffic indication message period in multiples of beacon
intervals. This value needs to be between 1 and 255. The default
setting is 3.
Select one of the following radio buttons to specify the preamble type:
• Long. A long transmit preamble might provide a more reliable
connection or a slightly longer range. A short transmit preamble
gives better performance.
• Auto. The Auto setting enables the wireless access point to handle
both long and short preambles. The default setting is Auto.
Select one of the following radio buttons to specify the antenna:
• Internal. Enables the internal antenna. This is the default setting.
• External. Enables an optional external antenna or antennas.
Select this check box to enable support for additional regulatory
domains that are not in the current standard; support includes the
addition of a country information element to beacons, probe requests,
and probe responses. This check box is selected by default.
