•

Access Point:

Select Activated to allow wireless station to associate with the access

point.

•

Channel:

Select the country and channel you want to use from the drop-down List of

Channel. This field determines which operating frequency will be used. It is not

necessary to change the wireless channel unless you notice interference problems with

another nearby access point.

•

Beacon Interval:

Enter a value between 20-1000 milliseconds. The Beacon Interval

value indicates the frequency interval of the beacon. A beacon is a packet broadcast by

the Router to synchronize the wireless network. The default value is 100.

•

RTS/CTS Threshold:

Should you encounter inconsistent data flow, only minor reduction

of the default value 2347 is recommended. If a network packet is smaller than the preset

RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends

Request to Send (RTS) frames to a particular receiving station and negotiates the

sending of a data frame. After receiving an RTS, the wireless station responds with a

Clear to Send (CTS) frame to acknowledge the right to begin transmission. In most cases,

keep its default value of 2347.

•

Fragmentation Threshold:

This value specifies the maximum size for a packet before

data is fragmented into multiple packets. If you experience a high packet error rate, you

may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold

too low may result in poor network performance. Only minor reduction of the default value

is recommended. In most cases, it should remain at its default value of 2346.

•

DTIM:

This value, between 1 and 255, indicates 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. Its clients hear the beacons and awaken to receive the broadcast

and multicast messages. The default value is 1.

•

Wireless Mode:

In the drop-down list you can select “802.11n”, “802.11g”, “802.11b” or

"802.11 b+g ","802.11 g+n ", "802.11 b+g+n " allows both 802.11g, 802.11b and 802.11n

wireless stations to connect to the Router.

¾

11n Settings:

These are the settings of the 11n parameters. If “802.11n”, “802.11g+n” or

“802.11b+g+n” is selected for

Wireless mode

, these settings will be displayed.

•

Channel Bandwidth:

Select the Bandwidth you want to use from the drop-down List.

There are two options, “20 MHz” and “20/40 MHz”. If bigger bandwidth is selected, device

could transmit and receive data with higher speed.

•

Extension Channel:

If “20/40 MHz” is selected, this option will be displayed.

•

Guard Interval:

Select the guard interval you want from the drop-down list.

•

MCS:

Select the wireless transmission rate from the drop-down list. By default, the option

is AUTO.

¾

Multiple SSIDs Settings:

These are the settings of the SSID.

•

SSID Index:

The index of the SSID, and in this model, you can only leave it as a default

value of 1.

•

Broadcast SSID:

When wireless clients survey the local area for wireless networks to

associate with, they will detect the SSID broadcast by the Router. To broadcast the

Router’s SSID, keep the default setting. If you don’t want to broadcast the Router’s SSID,

select “No”.

•

Use QSS:

Use QSS (Wi-Fi Protected Setup) function, you can add a new wireless device

to an existing network quickly. To Use QSS, keep the default setting, and configure the

parameters in

QSS Settings

. If you don’t want to Use QSS, select “No”, then you will see

the screen as shown below.

Figure 4-13

•

SSID:

Wireless network name shared among all points in a wireless network. The SSID

must be identical for all devices in the wireless network. It is case-sensitive and must not

exceed 32 characters (use any of the characters on the keyboard). Make sure this setting

is the same for all stations in your wireless network. Type the desired SSID in the space

provided.

•

Authentication Type:

Select an authentication type from the drop-down list, which

allows you to configure security features of the wireless LAN interface. Options available

are:

Disabled,

WEP-64Bits,

WEP-128Bits,

WPA-PSK,

WPA2-PSK

and

WPA-PSK/WPA2-PSK.

)

Note:

For most users, it is recommended to use the default Wireless LAN Performance settings. Any

changes made to these settings may adversely affect your wireless network. Under certain

circumstances, changes may benefit performance. Carefully consider and evaluate any changes

to these wireless settings.

1)

WEP-64Bits

To configure WPA-64Bits settings, select the WPA-64Bits option from the drop-down list. The

menu will change to offer the appropriate settings. WPA-64Bits is a data privacy mechanism

based on a 64-bit shared key algorithm, as described in the IEEE 802.11g standard.

2)

WEP-128Bits

To configure WPA-128Bits settings, select the WPA-128Bits option from the drop-down list. The

menu will change to offer the appropriate settings. 128-bit is stronger than 64-bit.

Figure 4-15

3)

WPA-PSK

To configure WPA-PSK settings, select the WPA-PSK option from the drop-down list. The menu

will change to offer the appropriate settings. WPA-PSK requires a shared key and does not use a

separate server for authentication. PSK keys can be ASCII or Hex type.

Encryption:

Select the encryption you want to use: TKIP or AES (AES is an encryption

method stronger than TKIP).
