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.

Default Used WEP Key:

Select the encryption key ID; please refer to

Key (1~4)

below.

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.

Wireless Client Filter

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.

Filter Action:

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.

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,

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:

There are Six options to choose from: Auto, disable, 10M half-duplex, 10M

full-duplex, 100M half-duplex, 100M full-duplex and Disable. 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.

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 192.168.0.254).

To configure the router’s DHCP Server, check

DHCP Server

and

click

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

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

.

Some of ISP may provide more service via different WAN connection. In case, you can create more

connections by clicking

Create

. The device can support maximum up to 8 WAN connections.

Note:

The application of multiple WAN connections is depend on your Service Provider.

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.
