MAC Address : The MAC address of the Wireless interface is displayed here.
Band Mode : Select an appropriate wireless band; bands available are 801.11a or
802.11a/n mixed mode.
AP Isolation : Select Enable, all clients will be isolated from each VAP, that means
different VAP's clients can not reach to each other.
Transmit Rate Control : Select the desired rate from the drop-down list; the options
are auto or ranging from 6 to 54Mbps only for 802.11a mode.
Tx Power : You can adjust the output power of the system to get the appropriate
coverage for your wireless network. Specify digit numbers between 1 to 100 (the
unit is %) for your environment. If you are not sure which setting to choose, then
keep the default setting, 100%.
When Band Mode select in 802.11a only mode, the HT(High Throughput) settings
should be hidden immediately.
HT TxStream/RxStream : By default, it's 2.
Operating Mode : By default, it's Mixed Mode.
Mixed Mode : In this mode packets are transmitted with a preamble
compatible with the legacy 802.11a/g, the rest of the packet has a new format.
In this mode the receiver shall be able to decode both the Mixed Mode
packets and legacy packets.
Green Field : In this mode high throughput packets are transmitted without a
legacy compatible part.
Channel Bandwidth : The "20/40" MHz option is usually best. The other option is
available for special circumstances.
Guard Interval : Using "Auto" option can increase throughput. However, it can also
increase error rate in some installations, due to increased sensitivity to radio-
frequency reflections. Select the option that works best for your installation.
MCS : This parameter represents transmission rate. By default (Auto) the fastest
possible transmission rate will be selected. You have the option of selecting the
speed if necessary. (Refer to Appendix C. MCS Data Rate)
Reverse Direction Grant(RDG) : Disable or enable reserve direction grant. Default is
enabled.
A-MSDU : Aggregated Mac Service Data Unit. Select Enable to allow aggregation for
multiple MSDUs in one MPDU Default is disabled.
Auto Block ACK : Disable or enable auto block ACK. Default is enabled.
Decline BA Request : Disable or enable decline BA request. Default is disabled.

Wireless Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per
requirements properly, not necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings
for the system. Please click on Wireless -> Advanced Setup and follow the below setting.
Short Slot : By default, it's "Enable" for educing the slot time from the standard 20
microseconds to the 9 microsecond short slot time
Slot time is the amount of time a device waits after a collision before retransmitting
a packet. Reducing the slot time decreases the overall back-off, which increases
throughput. Back-off, which is a multiple of the slot time, is the random length of
time a station waits before sending a packet on the LAN. For a sender and receiver
own right of the channel the shorter slot time help manage shorter wait time to re-
transmit from collision because of hidden wireless clients or other causes. When
collision sources can be removed sooner and other senders attempting to send are
listening the channel(CSMA/CA) the owner of the channel should continue
ownership and finish their transmission and release the channel. Then, following
ownership of the channel will be sooner for the new pair due to shorter slot time.
However, when long duration of existing collision sources and shorter slot time exist
