Advanced

Fragment Threshold:

Specifies the size of the packet per fragment.

This function can reduce the chance of packet collision.

However when this value is set too low, there will be increased overheads

resulting in poor performance.

RTS Threshold:

When the packet size is smaller than the RTS Threshold, then the packet will

be sent without RTS/CTS handshake which may result in incorrect

transmission.

Beacon Interval:

The time interval that the device broadcasts a beacon. This beacon is used to

synchronize all wireless clients on the network.

DTIM Period:

A Delivery Traffic Indication Message informs all wireless clients that the

access point will be sending Multi-casted data.

N Data Rate:

You can limit the transfer rates between the device and wireless clients. Each

Modulation Coding Scheme (MCS) refers to a specific transfer speed.

Channel Bandwidth:

Set whether each channel uses 20 or 40Mhz.

To achieve 11n speeds, 40Mhz channels must be used.

Preamble Type:

A preamble is a message that helps access points synchronize with the client.

Long Preamble is standard based so increases compatibility.

Short Preamble is non-standard, so it decreases compatibility but increases

performance.

CTS Protection:

When Enabled, the performance is slightly lower however the chances of

packet collision is greatly reduced.

Tx Power:

Set the power output of the wireless signal.
