Chapter 1: Introduction
Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multi-
function device providing the following services:
• Shared Broadband Internet Access for all LAN users.
• 4-Port Switching Hub for 10BaseT or 100BaseT connections.
• Wireless Access Point for 802.11b and 802.11g Wireless Stations.
Wireless Router Features
The Wireless Router incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
Internet Access Features
• Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Wireless Router, using only a single external IP Address. The local (invalid)
IP Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).
• DSL & Cable Modem Support. The Wireless Router has a 10/100BaseT Ethernet port
for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are sup-
ported. SingTel RAS and Big Pond (Australia) login support is also included.
• PPPoE, and PPTP. The Internet (WAN port) connection supports PPPoE (PPP over
Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct Connection" type
services. Unnumbered IP with PPPoE is also supported.
• Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless
Router supports both Dynamic IP Address (IP Address is allocated on connection) and
Fixed IP Address.
Advanced Internet Functions
• Communication Applications. Support for Internet communication applications, such
as interactive Games, Telephony, and Conferencing applications, which are often difficult
to use when behind a Firewall, is included.
Page 3 of 55

Page 4 of 55
• Special Internet Applications. Applications which use non-standard connections or
port numbers are normally blocked by the Firewall. The ability to define and allow such
applications is provided, to enable such applications to be used normally.
• Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
• DDNS Support. DDNS (Dynamic DNS) allows Internet users to connect to Virtual
Servers on your LAN using a domain name, even if your IP address is not fixed.
• DMZ. For each WAN (Internet) IP address allocated to you, only one (1) PC on your
local LAN can be configured to allow unrestricted 2-way communication with Servers or
individual users on the Internet. This provides the ability to run programs which are in-
compatible with Firewalls.
• URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
• Internet Access Log. See which Internet connections have been made.
• Access Control. Using the Access Control feature, you can assign LAN users to differ-
ent groups, and determine which Internet services are available to each group.
• VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
Wireless Features
• Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS)
specifications for Wireless LANs.
• Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard
provides for backward compatibility with the 802.11b standard, so both 802.11b and
802.11g Wireless stations can be used simultaneously.
• Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported.
• WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of
64 Bit and 128 Bit are supported.
• Wireless MAC Access Control. The Wireless Access Control feature can check the
MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless
Stations can access your LAN.
• Simple Configuration. If the default settings are unsuitable, they can be changed
quickly and easily.
LAN Features
• 4-Port Switching Hub. The Wireless Router incorporates a 4-port 10/100BaseT switch-
ing hub, making it easy to create or extend your LAN.
• DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Wireless Router can act as a DHCP
Server for devices on your local LAN and WLAN.
• .
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-
ration.
• Configuration File Upload/Download. Save (download) the configuration data from
the Wireless Router to your PC, and restore (upload) a previously saved configuration file
to the Wireless Router.

Page 5 of 55
• Remote Management. The Wireless Router can be managed from any PC on your
LAN. And, if the Internet connection exists, it can also (optionally) be configured via the
Internet.
• Network Diagnostics. You can use the Wireless Router to perform a Ping or DNS
lookup.
• UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and con-
figuration of the Wireless Router. UPnP is by supported by Windows ME, XP, or later.
Security Features
• Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
• Wireless LAN Security. WEP (Wired Equivalent Privacy) is supported, as well as
Wireless access control to prevent unknown wireless stations from accessing your LAN.
• NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology is that by allowing all LAN users to share a single IP address, the location and
even the existence of each PC is hidden. From the external viewpoint, there is no network,
only a single device - the Wireless Router.
• Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much band-
width and so many resources that Internet access becomes unavailable. The Wireless
Router incorporates protection against DoS attacks.

About the Operation Mode
AP Mode
When acting as an access point, this device connects all the stations (PC/notebook with wire-
less network adapter) to a wired network. All stations can have the Internet access if only the
Access Point has the Internet connection.
Bridge Mode
The WDS (Wireless Distributed System) function lets this access point act as a wireless LAN
access point and repeater at the same time. Users can use this feature to build up a large wire-
less network in a large space like airports, hotels and schools …etc. This feature is also useful
when users want to bridge networks between buildings where it is impossible to deploy net-
work cable connections between these buildings.
Repeater
Refer to the illustration below. While acting as Bridges, AP1 (with Station 1 being associated
to) and AP2 (with Station 2 being associated) can communicate with each other through
wireless interface (with WDS). Thus Station 1 can communicate with Station 2 and both
Station 1 and Station 2 are able to access the Internet if only AP1 or AP2 has the Internet
connection.
To set the operation mode to Bridge, please go to “Wireless JBasic Settings”, in the “Mode”
field click the down arrow bto select AP mode. And go to “Wireless JWDS Settings” to
enable WDS.

Preparation
Before attempting to configure the Wireless Router, please ensure that:
• Your PC can establish a physical connection to the Wireless Router. The PC and the
Wireless Router must be directly connected (using the Hub ports on the Wireless Router)
or on the same LAN segment.
• The Wireless Router must be installed and powered ON.
• If the Wireless Router's default IP Address (192.168.1.254) is already used by another
device, the other device must be turned OFF until the Wireless Router is allocated a new
IP Address during configuration.
Using UPnP
If your Windows system supports UPnP, an icon for the Wireless Router will appear in the
system tray, notifying you that a new network device has been found, and offering to create a
new desktop shortcut to the newly-discovered device.
• Unless you intend to change the IP Address of the Wireless Router, you can accept the
desktop shortcut.
• Whether you accept the desktop shortcut or not, you can always find UPnP devices in My
Network Places (previously called Network Neighborhood).
• Double - click the icon for the Wireless Router (either on the Desktop, or in My Network
Places) to start the configuration. Refer to the following section Setup Wizard for details
of the initial configuration process.

Using your Web Browser
To establish a connection from your PC to the Wireless Router:
1. After installing the Wireless Router in your LAN, start your PC. If your PC is already
running, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the Wireless Router, as in this
example, which uses the Wireless Router's default IP Address:
HTTP://192.168.1.254
No username and password required for the first login (default setting). However, you can
assign a set of username and password for future security. See the Password Setup section later
in this chapter for details.
If you can't connect
If the Wireless Router does not respond, check the following:
• The Wireless Router is properly installed, LAN connection is OK, and it is
powered ON. You can test the connection by using the "Ping" command:
• Open the MS-DOS window or command prompt window.
• Enter the command:
ping 192.168.1.254
If no response is received, either the connection is not working, or your
PC's IP address is not compatible with the Wireless Router's IP Address.
(See next item.)
• If your PC is using a fixed IP Address, its IP Address must be within the range
192.168.1.1 to 192.168.1.253 to be compatible with the Wireless Router's de-
fault IP Address of 192.168.1.254. Also, the Network Mask must be set to
255.255.255.0. See Chapter 4 - PC Configuration for details on checking your
PC's TCP/IP settings.
• Ensure that your PC and the Wireless Router are on the same network seg-
ment. (If you don't have a router, this must be the case.)
• Ensure you are using the wired LAN interface. The Wireless interface can only
be used if its configuration matches your PC's wireless settings.
