DG-BG4300N User Manual

This page allows advanced users who have sufficient knowledge of wireless LAN to

configure advanced settings. These setting shall not be changed unless you know exactly

what will happen from the changes you made on your DSL device.

Fields in this page:

Fragment

Threshold

This value should remain at its default setting of 2346. It 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 increases the “Fragment Threshold” value within the value range of

256 to 2346. Setting this value too low may result in poor network performance. Only minor

modifications of this value are recommended.

RTS Threshold

This value should remain at its default setting of 2347. If you encounter inconsistent data

flow, only minor modifications are recommended. If a network packet is smaller than the

preset “RTS threshold” size, the RTS/CTS mechanism will not be enabled. The ADSL

modem (or AP) 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.

Beacon

Interval

The Beacon Interval value indicates the frequency interval of the beacon. Enter a value

between 20 and 1024. A beacon is a packet broadcast by the ADSL modem (or AP) to

synchronize the wireless network. The default is 100.

Data Rate

The rate of data transmission should be set depending on the speed of your wireless

network. You should select from a range of transmission speeds, or you can select Auto to

have the ADSL modem (or AP) automatically use the fastest possible data rate and enable

the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed

between the AP and a wireless client. The default setting is Auto.

Preamble Type

The Preamble Type defines the length of the CRC (Cyclic Redundancy Check) block for

communication between the AP and mobile wireless stations. Make sure to select the

appropriate preamble type. Note that high network traffic areas should use the short

preamble type. CRC is a common technique for detecting data transmission errors.

Broadcast

SSID

If this option is enabled, clients can see the wireless network. This feature is intended to

allow clients to dynamically discover and roam between WLANs; if this option is disabled,

the device will hide its SSID. When this is done, the station cannot directly discover its

WLAN and MUST be configured with the SSID. Note that in a home Wi-Fi network, roaming

is largely unnecessary and the SSID broadcast feature serves no useful purpose. You

should disable this feature to improve the security of your WLAN.

Relay Blocking

When Relay Blocking is enabled, wireless clients will not associate with other wireless

clients.

Ethernet

to

Wireless

Blocking

When enabled, traffic between Ethernet and wireless interfaces are not allowed.

DTIM Interval

The DTIM Interval determines the number of AP beacons between each Delivery Traffic

Indication Message (DTIM). This informs clients of the next window for listening to broadcast

and multicast messages. When the AP has buffered broadcast or multicast messages for

associated clients, it sends the next DTIM with a DTIM Interval value. Clients for that AP

hear beacons and awaken to receive the broadcast and multicast messages

WIFI Multicast

to Unicast

For unicast transmissions, 802.11 implements layer2 acknowledgments and

error checking to ensure frame delivery. Multicast traffic, on the other hand, has no link layer

error or loss management in the 802.11 standard.

Aggregation

Frame aggregation is a process of packing multiple MSDUs or MPDUs together to reduce the

overheads and average them over multiple frames, thus increasing the user level data rate.

Short GI

Guard Intervals (GI) are used to ensure that distinct transmissions do not interfere with one

another. Short GI enable = 400ns, disable = 800ns.

5.3.6 WPS ( Wi-Fi Pprotected Setup)

Although home Wi-Fi networks have become more and more popular, users still have

trouble with the initial set up of network. This obstacle forces users to use the open

security and increases the risk of eavesdropping. Therefore, The Wi-Fi Protected Setup

(WPS) is designed to ease set up of security-enabled Wi-Fi networks and subsequently

network management.

The largest difference between WPS-enabled devices and legacy devices is that users do

not need the knowledge about SSID, channel and security settings, but they could still surf

in a security-enabled Wi-Fi network.

This device supports Push Button method and PIN method for WPS. The following sub-

paragraphs will describe the function of each item. The webpage is shown below.

Field

Description

Disable WPS

Check to disable the Wi-Fi protected Setup.

WPS Status

When AP’s settings are factory default (out of box), it is set to open security and

un-

configured state. “WPS Status” will display it as “UnConfigured”. If it already

shows “Configured”, some registrars such as Vista WCN will not configure

AP.

Users will need to go to the “Backup/Restore” page and click “Reset” to reload

factory default settings.

Self-PIN Number

“Self

-

PIN Number” is AP’s PIN. Whenever users want to change AP’s PIN, they

could click “Regenerate PIN” and then click “ Apply Changes”. Moreover, if users

want to make their own PIN, they could enter four-digit PIN without checksum

and then click “ Apply Changes”. However, this would not be recommended since

the registrar side needs to be supported with four-digit PIN.

Push Button Configuration

Clicking this button will invoke the PBC method of WPS. It is only used when AP

acts as a registrar.

Client PIN Number

It is only used when users want their station to join AP’s network. The length of

PIN is limited to four or eight numeric digits. If users enter eight-digit PIN with

checksum error, there will be a warning message popping up. If users insist on

this PIN, AP will take it.

Function buttons in this page:

Regenerate PIN

Click to regenerate the Self-PIN Number.

Start PBC

Click to start the Push Button method of WPS.

Apply Changes

Click to commit changes.

Reset

It restores the original values.

Start PIN

Click to start the PIN method of WPS.

The end user can configure the Advance Setup

Route Configuration

The Routing page enables you to define specific route for your Internet and network data.

Most users do not need to define routes. On a typical small home or office LAN, the

existing routes that set up the default gateways for your LAN hosts and for the DSL device

provide the most appropriate path for all your Internet traffic.

On your LAN hosts, a default gateway directs all Internet traffic to the LAN port(s) on the

DSL device. Your LAN hosts know their default gateway either because you assigned it to

them when you modified your TCP/IP properties, or because you configured them to

receive the information dynamically from a server whenever they access the Internet.

On the DSL device itself, a default gateway is defined to direct all outbound Internet traffic

to a route at your ISP. The default gateway is assigned either automatically by your ISP

whenever the device negotiates an Internet access, or manually by user to setup through

the configuration.
