LAN Interface

Check it to disable the wireless function for ADSL modem.

Band

Select the appropriate band from the list provided to correspond with

your network setting.

Mode

The selections are: AP

SSID

The Service Set Identifier (SSID) or network name. It is case sensitive

and must not exceed 32 characters, which may be any keyboard

character. The mobile wireless stations shall select the same SSID to be

able to communicate with your ADSL modem (or AP).

Channel Number

Select the appropriate channel from the list provided to correspond with

your network settings. You shall assign a different channel for each AP to

avoid signal interference.

Radio Power (mW)

The maximum output power: 15mW, 30mW or 60mW.

Authentication

Type

Open System:

Open System authentication is not required to be successful

while a client may decline to authenticate with any particular other client.

Shared Key:

Shared Key is only available if the WEP option is implemented.

Shared Key authentication supports authentication of clients as either a

member of those who know a shared secret key or a member of those who

do not. IEEE 802.11 Shared Key authentication accomplishes this without the

need to transmit the secret key in clear. Requiring the use of the WEP privacy

mechanism.

Auto:

Auto is the default authentication algorithm. It will change its

authentication type automatically to fulfill client’s requirement.

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. Should you encounter

inconsistent data flow, only minor modifications are recommended. If a

network packet is smaller than the preset “RTS threshold” size, th

e 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, the device will automatically transmit their network

name (SSID) into open air at regular interval. 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 configure 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

is enabled, wireless clients will not be able to directly

access other wireless clients.

Ethernet to

Wireless

Blocking

When enabled, traffic between Ethernet and wireless interfaces are not

allowed.

WiFi Muticast

to Unicast

Router receives Multicast streams from the network backbone, converts

them to Unicast format, and routes them to the end-users over the last mile

infrastructure (e.g. DSL, Ethernet, WiFi).

(WMM) is a Wi-Fi Alliance interoperability certification, based on the IEEE

802.11e standard. It provides basic Quality of service (QoS) features to IEEE

802.11 networks. WMM prioritizes traffic according to four Access

Categories (AC) - voice, video, best effort, and background. However, it does

not provide guaranteed throughput. It is suitable for simple applications that

require QoS, such as Voice over IP (VoIP) on Wi-Fi phones (VoWLAN).

4.4.3

MBSSID

Multiple BSSID allows user to configure more than one virtual access point (VAP), each

virtual interface is assigned to its own basic service set identifier (BSSID), or MAC address,

which provides a better user experience. This is implemented in most off-the-shelf APs

equipped with the multiple SSID feature.
