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.

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.
