

Transmit Power:

Here you can specify the transmit power of modem router. You can select

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



Beacon Interval:

Enter a value between 25-1000 milliseconds for Beacon Interval here. The

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

Beacon Interval value determines the time interval of the beacons. The default value is 100.



RTS Threshold:

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

larger than the specified RTS Threshold size, the modem router will send RTS frames to a

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

2346.



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 because of excessive packets. 2346 is the default setting and is recommended.



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 modem 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.



Enable Short GI:

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

reducing the guard interval time

.



Enabled Client isolation:

This function can isolate wireless stations on your network from

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

each other. To use this function, check this box. Client isolation is disabled by default.



Enable WMM: WMM

function can guarantee the packets with high-priority messages being

transmitted preferentially. It is strongly recommended.



Note:

If you are not familiar with the setting items in this page, it's strongly recommended to keep the

provided default values; otherwise it may result in lower wireless network performance.
