Wireless Security ((Wireless)ADSL 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).

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.

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 0-2 are used to specify the priority

(precedence) of the packet, and bits 3-5 are specified the delay, throughput and reliability.

This feature uses bits 0-2 to classify the packet’s priority. If the packet is high priority, it will

flow first.

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 Precedence of TOS field matches the checked

values in the table (0 to 7), 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 192.168.1.254).

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.
