WEP

WEP Authentication:

There are three options to choose,

Open System, Shared Key

and

Both.

The default is set to Open System which does not request a shared key between the AP sender

and the AP client, only supplying a correct SSID and an encryption key if there is any.

With Share

Key authentication, the AP client is granted only if it provided correct challenge response to the AP.

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 (0-3)

as below when the

Passphrase

is enabled.

Default Used WEP Key:

Select the encryption key ID; please refer to

Key (0-3)

below.

Key (0-3):

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.

Wireless Client (MAC Address) Filter (Wireless Router only)

The MAC Address supports up to 16 wireless network machines and helps you to manage your

network control to accept traffic from specific authorized machines or to restrict unwanted

machine(s) to access your LAN.

There are no pre-define MAC Address filter rules; you can add the filter rules to meet your

requirements.

Ethernet Client Filter:

Default setting is set to

Disable

.

~

Allowed:

check to authorize specific device accessing your LAN by insert the MAC

Address in the space provided or click

.

Make sure your PC’s MAC is listed.

~

Blocked:

check to prevent unwanted device accessing the LAN by insert the MAC Address

in the space provided or click

. Make sure your PC’s MAC is not listed.

The maximum client is 16.

The MAC addresses are 6 bytes long; they are presented only in

hexadecimal characters.

Chapter 4: Configuration

Associate Wireless Client displays a list of individual wireless device’s MAC Address that currently

connects to the router.

You can easily by checking the box next to the MAC address to be blocked or allowed. Then,

Add

to insert to the Wireless Client (MAC Address) Filter table.

The maximum Ethernet client is 16.

Port Setting

This section allows you to configure the settings for the router’s Ethernet ports to solve some of the

compatibility problems that may be encountered while connecting to the Internet, as well allowing

users to tweak the performance of their network.

Port # Connection Type:

Five options to choose from: Auto, 10M half-duplex, 10M full-duplex,

100M half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility problems with

legacy Ethernet devices, and you can configure different types to solve compatibility issues. The

default is

Auto

, which users should keep unless there are specific problems with PCs not being

able to access your LAN.

IPv4 TOS priority Control (Advanced users):

TOS, Type of Services, is the 2

nd

octet of an IP

packet. Bits 6-7 of this octet are reserved and bit 0-5 are used to specify the priority

of the packet.

This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it will flow first and

will not be constrained by the Rate Limit.

Therefore, when this feature is enabled, the router’s Ethernet

switch will check the 2

nd

octet of each IP packet. If the value in the TOS field matches the checked

values in the table (0 to 63), this packet will be treated as high priority.

Chapter 4: Configuration

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 will need to manually assign a fixed IP address to each PCs on your

network, and set the default gateway for each PCs to the IP address of the router (by default this 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 will perform the domain name lookup, find the IP address from the outside

network automatically and forward it back to the requesting PC in the LAN (your Local Area

Network).

If you check

DHCP Relay Agent

and click

Next

, then you will have to enter the IP address of the

DHCP server which will assign 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.

WAN (Wide Area Network)

WAN refers to your Wide Area Network connection, i.e. your router’s connection to your ISP and the

Internet. There are two items within the

WAN

section:

ISP

,

DNS

and

ADSL

.

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. Please see the Quick

Start section of the manual for more information.
