Ethernet
Primary IP Address
IP Address:
The default IP on this router.
Subnet Mask:
The default subnet mask on this router.
RIP:
RIP v1, RIP v2, and RIP v2 Multicast.
Check to enable RIP function.
IP Alias
This function supports to create multiple virtual IP interfaces on this router. It helps to connect two or
more local networks to the ISP or remote node. In this case, an internal router is not required.
IP Address:
Specify an IP address on this virtual interface.
SubNetmask:
Specify a subnet mask on this virtual interface.
Security Interface:
Specify the firewall setting on this virtual interface.
Internal:
The network is behind NAT. All traffic will do network address translation when sending out to
Internet if NAT is enabled.
External:
There is no NAT on this IP interface and connected to the Internet directly. Mostly, it will be
used when providing multiple public IP addresses by ISP. In this case, you can use public IP address in
local network which gateway IP address point to the IP address on this interface.
DMZ:
Specify this network to DMZ area. There is no NAT on this interface.

Ethernet Client Filter
The Ethernet Client Filter supports up to 16 Ethernet network machines that helps you to manage your
network control to accept traffic from specific authorized machines or can restrict unwanted machine(s)
to access your LAN.
There are no pre-define Ethernet 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 your 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.
The number

Active PC in LAN displays a list of individual Ethernet device’s IP Address & MAC Address which
connecting to the router.
You can easily by checking the box next to the IP address to be blocked or allowed. Then,
Add
to insert
to the Ethernet Client Filter table.
The maximum Ethernet client is 16.
Wireless
Mutiple APs
AP Index:
you can select “ Main”, “ Virtual AP1” and “Virtual AP2”
Parameters
WLAN Service:
Default setting is set to
Enable
.
If you do not have any wireless, both 802.11g and
802.11b, device in your network, select
Disable.
Mode:
The default setting is
802.11b+g
(Mixed mode). If you do not know or have both 11g and 11b
devices in your network, then keep the default in
mixed mode
.
From the drop-down manual, you can
select
802.11g
if you have only 11g card.
If you have only 11b card, then select
802.11b
.
ESSID:
The ESSID is the unique name of a wireless access point (AP) to be distinguished from another.
For security propose, change the default
wlan-ap
to
a unique ID name to the AP which is already built-in
to the router’s wireless interface. It is case sensitive and must not excess 32 characters. Make sure your
wireless clients have exactly the ESSID as the device, in order to get connected to your network.
Note:
It is case sensitive and must not excess 32 characters
.
ESSID Broadcast:
It is function in which transmits its ESSID to the air so that when wireless client
searches for a network, router can then be discovered and recognized. Default setting is
Enable.

±
Disable:
If you do not want broadcast your ESSID.
Any client uses “any” wireless setting cannot
discover the Access Point (AP) of your router.
±
Enable:
Any client that using the “any” setting can discover the Access Point (AP) in
Regulation Domain:
There are seven Regulation Domains for you to choose from, including North
America (N.America), Europe, France, etc. The Channel ID will be different based on this setting.
Channel ID:
Select the wireless connection ID channel that you would like to use.
Use the
Scan
Channel Usage
to help to select non-occupied wireless channel.
±
Scan Channel Usage:
Wireless channel scan takes up to 14 seconds to survey the channel ID
in the network area.
The result will show all ID channel is being occupied or not occupied.
Note:
Wireless performance may degrade if select ID channel is already being occupied by other AP(s).
TX PowerLevel:
It is function that enhances the wireless transmitting signal strength.
User may adjust
this power level from minimum 0 up to maximum 255.
Note:
The Power Level maybe different in each access network user premises environment and choose the most
suitable level for your network.
Connected:
Representing in
true
or
false
. That it is the connection status between the system and the
build-in wireless card.
AP MAC Address:
It is a unique hardware address of the Access Point.
AP Firmware Version:
The Access Point firmware version.
Wireless Distribution System (WDS)
It is a wireless access point mode that enables wireless link and communication with other access point.
It is easy to be installed simply define peer’s MAC address of the connected AP. WDS takes advantages
of cost saving and flexibility which no extra wireless client device is required to bridge between two
access points and extending an existing wired or wireless infrastructure network to create a larger
network. It can connect up to 1 wireless APs for extending cover range at the same time.
In addition, WDS enhances its link connection security in WEP mode, WEP key encryption must be the
same for both access points.
WDS Service:
The default setting is
Disabled.
Check
Enable
radio button to activate this function.
1. Peer WDS MAC Address:
It is the associated AP’s MAC Address. It is important that your peer’s AP
must include your MAC address in order to acknowledge and communicate with each other.
Note:
For MAC Address, Semicolon ( : ) must be included.

Wireless Security
You can disable or enable with WPA or WEP for protecting wireless network. The default mode of
wireless security is
disabled
.
WPA-PSK (TKIP) / WPA-PSK (AES) Pre-Shared Key
WPA Algorithms:
There are two types of the WPA-PSK, WPA1 and WPA2.
The WPA1 adapts the
TKIP (Temporal Key Integrity Protocol) encrypted algorithms which incorporates Message Integrity Code
(MIC) to provide protection against hackers. The WPA2 adapts CCMP (Cipher Block Chaining Message
Authentication Code Protocol) of the AES (Advanced Encryption Security) algorithms.
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
3600
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.
