

Access point Settings:

These are the settings of the access point. You can configure the

rules to allow wireless-equipped computers and other devices to communicate with a

wireless network.



Access point:

Select Activated to allow wireless station to associate with the access

point.



Channel:

Select the 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.



Transmit Power:

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

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

recommended.



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 modem 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 modem 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 modem 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 “802.11b”, “802.11g”, “802.11n”,

“802.11b+g”, “802.11g+n” and “802.11b+g+n”. “802.11b+g+n” allows both 802.11b,

802.11g and 802.11n wireless stations to connect to the modem router.



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.



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 modem router. To broadcast

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

modem router’s SSID, select “No”.



Use WPS:

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

device to an existing network quickly. To Use WPS, keep the default setting, and

configure the parameters in

WPS Settings

. If you don’t want to Use WPS, select “No”,

then you will see the screen as shown below.

Figure 4-15



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.

1)

WEP- 64Bits

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

menu will change to offer the appropriate settings. WEP-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 WEP-128Bits settings, select the WEP-128Bits option from the drop-down list.

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

Figure 4-17

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.
