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 an RTS/CTS handshake which may result in an 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.
A Long Preamble is standard based so it increases compatibility.
A 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.
