4.3.1 LAN (Local Area Network)

A Local Area Network (LAN) is a shared communication system to which many computers

are attached and is limited to the immediate area, usually the same building or floor of a

building.

4.3.1.1 Ethernet

The router supports two Ethernet IP addresses in the LAN, and two different LAN subnets

through which you can access the Internet at the same time. Users usually only have one

subnet in their LAN, so there is no need to configure a Secondary IP address. The default IP

address for the router is 192.168.1.254.

RIP:

RIP v1, RIP v2, RIP v1+v2 and RIP v2 Multicast.

The Subnet mask of the Secondary IP Address depends on the setting

of the Primary IP Address.

of the Primary IP Address.

4.3.1.2 Wireless

Parameters

Mode:

802.11b + g (Mixed mode), 802.11b and 802.11g. The factory default is 802.11b +

g.

ESSID:

Enter the unique ID given to the Access Point (AP), which is already built-in to the

router’s wireless interface. To connect to this device, your wireless clients must have the

same ESSID as the device.

Regulation Domain:

There are five Regulation Domains for you to choose from,

including

North America (N.America)

,

Europe

,

France

, etc. The Channel ID will be

different based on this setting.

Channel ID:

Select the ID channel that you would like to use.

MAC Address:

The AP’s MAC Address

AP Version:

The Access Point firmware version.

Wireless Distribution System (WDS)

It is a wireless access point mode that enables wireless link and communication with other

access point.

It is easy to be installed simply define peer’s MAC address of the connected

AP.

WDS takes advantages of cost saving and flexibility which no extra wireless client

device is required to bridge between two access points and extending an existing wired or

wireless infrastructure network to create a larger network.

In addition, WDS enhances its link connection security in WEP mode, WEP key encryption

must be the same for both access points.

WDS Service:

The default setting is

Disable.

Check

Enable

radio button to activate this

function.

Peer WDS MAC Address:

It is the associated AP’s MAC Address.

It is important that

your peer’s AP must include your MAC address in order to acknowledge and communicate

with each other.

(

Note

: For MAC Address, Semicolon (

:

) must be included)

4.3.1.3 Wireless Security

You can disable or enable with WPA or WEP for protecting wireless network.

The default mode of wireless security is

disabled

.

WPA Pre-Shared Key

WPA Algorithms:

TKIP (Temporal Key Integrity Protocol) utilizes a stronger encryption

method and incorporates Message Integrity Code (MIC) to provide protection against

hackers.

WPA Shared Key:

The key for

network authentication

.

The input format is in character

style and key size should be in the range between 8 and 63 characters.

Group Key Renewal:

The period of renewal time for changing the security key

automatically between wireless client and Access Point (AP).

Hide ESSID:

User can select Enable or Disable to hide ESSID.

WEP

WEP Encryption:

To prevent unauthorized wireless stations from accessing data

transmitted over the network, the router offers highly secure data encryption, known as WEP.

If you require high security for transmissions, there are two alternatives to select from:

WEP

64 and WEP 128

. WEP 128 will offer increased security over WEP 64.

Passphrase:

This is used to generate WEP keys automatically based upon the input

string and a pre-defined algorithm in WEP64 or WEP128. You can input the same string in

both the AP and Client card settings to generate the same WEP keys. Please note that you

do not have to enter

Key (1-4)

as below when the

Passphrase

is enabled..

Key (1-4):

Enter the key to encrypt wireless data. To allow encrypted data transmission,

the WEP Encryption Key values on all wireless stations must be the same as the router.

There are four keys for your selection. The input format is in HEX style, 5 and 13 HEX codes

are required for WEP64 and WEP128 respectively, the separator is “-“. For example, using

WEP64, 11-22-33-44-55 is a valid key, whilst 1122334455 is invalid.

Hide ESSID:

User can select Enable or Disable to hide ESSID.

4.3.1.4 DHCP Server

You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or

enable the router’s DHCP relay functions. The DHCP protocol allows your router to

dynamically assign IP addresses to PCs on your network if they are configured to obtain IP

addresses automatically.

To disable the router’s DHCP Server, check

Disabled

and click

Next

then click

Apply.

When the DHCP Server is disabled you need to manually assign a fixed IP address to each

PC on your network, and set the default gateway for each PC to the IP address of the router

(the default is 192.168.1.254).

To configure the router’s DHCP Server, check

DHCP Server

and

click

Next

. You can then

configure parameters of the DHCP Server including the IP pool (starting IP address and

ending IP address to be allocated to PCs on your network), lease time for each assigned IP

address (the period of time the IP address assigned will be valid), DNS IP address and the

gateway IP address. These details are sent to the DHCP client (i.e. your PC) when it

requests an IP address from the DHCP server. Click

Apply

to enable this function. If you

check “

Use Router as a DNS Server

”, the ADSL Router performs the domain name lookup,

finds the IP address from the outside network automatically and forwards it back to the

requesting PC in the LAN (your Local Area Network).
