Wireless

This section introduces the wireless LAN and some basic configurations. Wireless

LANs can be as simple as two computers with wireless LAN cards communicating in

a peer-to-peer network or as complex as a number of computers with wireless LAN

cards communicating through access points which bridge network traffic to the

wired LAN.

wireless, both 802.11g and 802.11b, device in your network,

select

Deactived

.

Channel

Select from combo box the country in order to make the device

fully compliant with regional laws.

Channel ID

The range of radio frequencies used by IEEE 802.11b/g/n

wireless devices is called a channel.

Select a channel from the drop-down list box.

Current Channel

Show current channel using from WebShare 141W.

Transmit Power

User can customize the transmit power to either high, medium

or low.

Beacon Interval

The Beacon Interval value indicates the frequency interval of the

beacon. Enter a value between 20 and 1000.

A beacon is a packet broadcast by the Router to synchronize the

wireless network.

RTS/CTS

The RTS (Request To Send) threshold (number of bytes) for

enabling RTS/CTS handshake. Data with its frame size larger

than this value will perform the RTS/CTS handshake. Setting this

attribute to be larger than the maximum MSDU (MAC service

data unit) size turns off the RTS/CTS handshake. Setting this

attribute to zero turns on the RTS/CTS handshake. Enter a value

between 1500 and 2347.

Fragmentation

Threshold

The threshold (number of bytes) for the fragmentation boundary

for directed messages. It is the maximum data fragment size

that can be sent. Enter a value between 256 and 2346.

DTIM

This value, between 1 and 255, indicates the interval of the

Delivery Traffic Indication Message (DTIM).

802.11 n/g/b

The default setting is 802.11b+g+n (Mixed mode). If you do not

know or have both 11g and 11b devices in your network, then

keep the default in mixed mode. From the drop-down manual,

you can select 802.11g if you have only 11g card. If you have

only 11b card, then select 802.11b.

The range of radio frequencies used by IEEE 802.11g wireless

devices is called a “channel”. Channels available depend on your

geographical area. You may have a choice of channels (for your

region) so you should use a different channel than an adjacent AP

(access point) to reduce interference. Interference occurs when

radio signals from different access points overlap causing

interference and degrading performance.

Adjacent channels partially overlap however. To avoid interference

Page 43 / 105

due to overlap, your AP should be on a channel at least five

channels away from a channel that an adjacent AP is using. For

example, if your region has 11 channels and an adjacent AP is using

channel 1, then you need to select a channel between 6 or 11.

MULTIPLE SSID SETTINGS

Field

Description

SSID Index

Default SSID index is “1”

.

Broacast SSSID

Select Yes to make the SSID visible so a station can obtain the

SSID through passive scanning. Select No to hide the SSID in so

a station cannot obtain the SSID through passive scanning.

SSSID

The SSID is the unique name of a wireless access point (AP) to

be distinguished from another. For security propose, change the

default wlan-ap to a unique ID name to the AP which is already

built-

in to the router’s wireless interface. It is case sensitive and

must not excess 32 characters. Make sure your wireless clients

have exactly the SSID as the device, in order to get connected

to your network.

Authentication

Type

To prevent unauthorized wireless stations from accessing data

transmitted over the network, the router offers highly secure

data encryption, known as WEP & WPA. If you require high

security for transmissions, there are four alternatives to select

from:

64-bit WEP

,

128-bit WEP

,

WPA-PSK

and

WPA2-PSK

.

WEP 128 will offer increased security over WEP 64.

You can disable or enable WPA or WEP for protecting wireless

network. The default type of wireless is disabled and to allow all

wireless computers to communicate with the access points

without any data encryption.
