Transmit Power - Here you can specify the transmit power of this device. 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 40-1000 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.
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.
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.
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.
Enable WMM - WMM function can guarantee the packets with high- priority messages

being transmitted preferentially. It is strongly recommended enabled.
Enable Short GI - This function is recommended for it will increase the data capacity by

reducing the guard interval time
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.
