2. Configure wireless advanced settings following the instructions below.

Region

Choose the region you are currently located.

Fragmentation

Enter the fragmentation bytes. The default value is 2346 bytes.

RTS

Enter the RTS seconds. The default value is 2347 seconds.

DTim

Enter the DTim seconds. The default value is 1.

Beacon Interval

Enter the interval to send a beacon. The default value is 100 milliseconds.

Header Preamble

Choose Long or Short header preamble.

TxMode

Choose different transmission mode.

MPDU

MPDU data length. The transmission rate is increase when you choose a

larger number, but usually the max value will be 4 in the wireless card

MSDU Aggregate

A kind of packet aggregation method, it can improve the transmission

efficiency. Please make sure you Wireless card has this function supported.

Tx Burst

Some 802.11g wireless card can supported this mode, and the transmission

rate can be increased when enable this function.

Packet Aggregate

An aggregation method like A-MSDU, it can improve the transmission

efficiency. Please make sure you Wireless card has this function supported.

HT Control Field

Choose Enable/Disable. It is useful when you need to debug the wireless

network

Reverse Direction Grant

Choose Enable/Disable. The response time can be shorter when enable this

increase the transmission rate when you using 802.11n wireless network only.

HT Band Width

Using HT20MHz or HT20/40MHz

Block Ack Setup

Automatically

Choose Enable/Disable. If your Wifi Card supported Block Ack mechanism,

it can improve the data transmission efficiency when enable this function.

Block Ack Window Size

Specify a Block Ack window size

Reject Block Ack

Choose Enable to reject the request of BA from other Wireless device

MCS

Select transmission (connection) speed.
