Transmit Power -

Here you can specify the transmit power of Router. You can select

High, Middle or Low which you would like. High is the default setting and is

recommended.

¾

Beacon Interval -

Enter a value between 20-1000 milliseconds for Beacon Interval here.

The beacons are the packets sent by the router to synchronize a wireless network.

Beacon Interval value determines the time interval of the beacons. The default value is

100.

¾

RTS Threshold -

Here you can specify the RTS (Request to Send) Threshold. If the

packet is larger than the specified RTS Threshold size, the router will send RTS frames

to a particular receiving station and negotiate the sending of a data frame. The default

value is 2346.

¾

Fragmentation Threshold -

This value is the maximum size determining whether

packets will be fragmented. Setting the Fragmentation Threshold too low may result in

poor network performance since excessive packets. 2346 is the default setting and is

recommended.

¾

DTIM Interval -

This value determines the interval of the Delivery Traffic Indication

Message (DTIM). A DTIM field is a countdown field informing clients of the next window

for listening to broadcast and multicast messages. When the Router has buffered

broadcast or multicast messages for associated clients, it sends the next DTIM with a

DTIM Interval value. You can specify the value between 1-255 Beacon Intervals. The

default value is 1, which indicates the DTIM Interval is the same as Beacon Interval.

¾

Enable WMM - WMM

function can guarantee the packets with high- priority messages

being transmitted preferentially. It is strongly recommended enabled.

¾

Enable Short GI -

This function is recommended for it will increase the data capacity by

reducing the guard interval time

.

¾

Enabled AP Isolation -

This function can isolate wireless stations on your network from

each other. Wireless devices will be able to communicate with the Router but not with

each other. To use this function, check this box. AP Isolation is disabled by default.
