Wireless Advanced

Choose menu “

Wireless Advanced

”, you can configure the advanced settings of

your wireless network.

Figure 4-24 Wireless Advanced

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.

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.

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 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 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 1-15 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.

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.

)

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.

addresses. 192.168.0.199 is the default end address.

Address Lease Time -

The

Address Lease Time

is the amount of time a network user will

be allowed connection to the Router with their current dynamic IP Address. Enter the

amount of time in minutes and the user will be "leased" this dynamic IP Address. After the

time is up, the user will be automatically assigned a new dynamic IP address. The range of

the time is 1 ~ 2880 minutes. The default value is 120 minutes.

Default Gateway -

(Optional.) It is suggested to input the IP address of the LAN port of the

Router. The default value is 192.168.0.1.
