Wireless Security (Wireless Router Only)

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).

Default value is

600

seconds.

Idle Timeout:

The default idle timeout is

3600

seconds.

A Timeout value base on the case of no

data traffic is send or received. If Router detects no traffic in the wireless, it will start timing the

clock and drop the session as it reaches to the defined timeout value. New session will be re-

established after the old session.

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 (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.

Associated Wireless Clients

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.

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.
