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.

3.6.3.1.4 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

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

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).

If you check

DHCP Relay Agent

and click

DHCP server which assigns an IP address back to the DHCP client in the LAN. Use this

function only if advised to do so by your network administrator or ISP. Click

Apply

to enable

this function.

3.6.3.2 WAN

Before you start installing this device, you have to check with your ISP what kind of service

(connection method) is provided such as PPPoE, PPPoA, RFC1483 bridged or routed, IPoA.

Gather the information as illustrated in the following table and keep it for reference.

PPPoE

VPI/VCI, VC-based/LLC-based multiplexing,

Username, Password, Service Name, and

Domain Name System (DNS) IP address (it can

be automatically assigned from ISP or be set

fixed).

PPPoA

VPI/VCI, VC-based/LLC-based multiplexing,

Username, Password, and Domain Name

System (DNS) IP address (it can be

automatically assigned from ISP or be set

fixed).

RFC1483

Bridged

VPI/VCI, VC-based/LLC-based multiplexing

RFC1483

Routed

VPI/VCI, VC-based/LLC-based multiplexing, IP

address, Subnet mask, Gateway address, and

Domain Name System (DNS) IP address (it is

fixed IP address).

IPoA

VPI/VCI, IP address, Subnet mask, Gateway

address, and Domain Name System (DNS) IP

address (it is fixed IP address).

A WAN (Wide Area Network) is an outside connection to another network or the Internet.

There are three items within the

WAN

section:

ISP

,

DNS

and

ADSL.

3.6.3.2.1 ISP

The factory default is PPPoE. If your ISP uses this access protocol, click

Edit

to input other

parameters as below. If your ISP does not use PPPoE, you can change the default WAN

connection entry by clicking

Change

.

A simpler alternative is to select

Quick Start

from the main menu on the left. See the Quick

Start section of the manual for more information.

PPPoE(RFC 2516) or PPPoA(RFC 2364)

PPPoE (PPP over Ethernet) provides access control in a manner similar to dial-up services

using PPP.

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). It provides

access control and billing functionality in a manner similar to dial-up services using PPP.

•

Description:

A user-definable name for this connection.

•

VPI/VCI:

Enter the information provided by your ISP.

•

NAT:

The NAT (Network Address Translation) feature allows multiple users to access

the Internet through a single ISP account, sharing a single IP address. If users on your

LAN have public IP addresses and can access the Internet directly, the NAT function

can be disabled.

•

Username:

Enter the username provided by your ISP. You can input up to

128

alphanumeric

characters

(case

sensitive).

This

is

in

the

format

of

“username@ispname” instead of simply “username”.

•

Password:

Enter the password provided by your ISP. You can input up to

128

alphanumeric characters (case sensitive).

•

Service Name:

This item is for identification purposes. If it is required, your ISP

provides you the information. Maximum input is

20

Your WAN IP address. Leave this at 0.0.0.0 to automatically obtain an IP

address from your ISP.

•

Authentication Protocol:

Default is

Chap.

Your ISP advises on using

Chap

or

Pap.
