Chapter 1
Introduction
This Chapter provides an overview of the Wireless Router's features
and capabilities.
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.
Figure 1: Wireless Router
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 Address 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 supported. SingTel RAS and Big Pond (Australia) login support is al-
so included.
PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet
(WAN port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer
Tunneling Protocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Di-
rect 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 applica-
tions, such as interactive Games, Telephony, and Conferencing applications,
which are often difficult to use when behind a Firewall, is included.
Special Internet Applications. Applications which use non-standard connec-
tions 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.
Multi-DMZ. For each WAN (Internet) IP address allocated to you, 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 pro-
grams which are incompatible 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 different 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 configura-
tion 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.
WPA support. Support for WPA is included. WPA is more secure than WEP,
and should be used if possible.
WPA2 support. Support for WPA2 is also included. WPA2 uses the extremely
secure AES encryption method.
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.
WDS Support. Support for WDS (Wireless Distribution System) allows the Wire-
less Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point
Bridge modes are supported.

Introduction
7
WPS Support. WPS (Wi-Fi Protected Setup) can simplify the process of con-
necting any device to the wireless network by using the push button configuration
(PBC) on the Wireless Access Point, or entering a 8-digit PIN code if there's no
button.
LAN Features
4-Port Switching Hub. The Wireless Router incorporates a 4-port
10/100BaseT switching 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.
Multi Segment LAN Support. LANs containing one or more segments are
supported, via the Wireless Router's RIP (Routing Information Protocol) support
and built-in static routing table.
Configuration & Management
Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for
configuration.
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.
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 confi-
gured 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
configuration 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)
technology is that by allowing all LAN users to share a single IP address, the loca-
tion and even the existence of each PC is hidden. From the external viewpoint,
there is no network, only a single device - the Wireless Router.
Firewall. All incoming data packets are monitored and all incoming server re-
quests are filtered, thus protecting your network from malicious attacks from
external sources.
Protection against DoS attacks. DoS (Denial of Service) attacks can flood
your Internet connection with invalid packets and connection requests, using so
much bandwidth and so many resources that Internet access becomes unavaila-
ble. The Wireless Router incorporates protection against DoS attacks.

The Wireless Router contains an HTTP server. This enables you to connect to it, and
configure it, using your Web Browser. Your Browser must support JavaScript.
The configuration program has been tested on the following browsers:
Netscape V4.08 or later
Internet Explorer V4 or later
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 Wire-
less Router) or on the same LAN segment.
The Wireless Router must be installed and powered ON.
If the Wireless Router's default IP Address (192.168.0.1) is already used by anoth-
er 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 devic-
es 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 Wi-
zard 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 al-
ready 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://192.168.0.1
Because the default password is blank, your will not be prompted for a password.
However, you should assign a password. See the Password section later in this chap-
ter for details.

Setup

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" com-
mand:
Open the MS-DOS window or command prompt window.
Enter the command:
ping 192.168.0.1
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 192.168.0.2 to 192.168.0.254 to be compatible with the Wireless
Router's default IP Address of 192.168.0.1. Also, the Network Mask
must be set to 255.255.255.0. See Chapter 4 - PC Configuration for de-
tails on checking your PC's TCP/IP settings.
Ensure that your PC and the Wireless Router are on the same network
segment. (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 set-
tings.

Use the default value unless the address is already in use or
your LAN is using a different IP address range. In the latter case,
enter an unused IP Address from within the range used by your
LAN.
Subnet Mask
The default value 255.255.255.0 is standard for small (class "C")
networks. For other networks, use the Network Mask for the LAN
segment to which the Wireless Router is attached. i.e. the same
value as the PCs on that LAN segment.
DHCP Server
If Enabled, the Wireless Router will allocate IP Addresses to
PCs (DHCP clients) on your LAN when they start up. The de-
fault (and recommended) value is Enabled.
If you are already using a DHCP Server, this setting must be
Disabled, and the existing DHCP server must be re-
configured to treat the Wireless Router as the default Gate-
way. See the following section for further details.
The Start IP Address and Finish IP Address fields set the
values used by the DHCP server when allocating IP Ad-
dresses to DHCP clients. This range also determines the
number of DHCP clients supported.
See the following section for further details on using DHCP.

Setup

Buttons
Save
Save any changes you have made. Note that if you change the
Wireless Router's IP address, your connection will be lost. You
will have to re-connect using the new IP address.
Cancel
The "Cancel" button will discard any data you have entered and
reload the file from the Wireless Router.
DHCP
What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to
a DHCP Client (PC or device) upon request.
The client request is made when the client device starts up (boots).
The DHCP Server provides the Gateway and DNS addresses to the client, as well
as allocating an IP Address.
The Wireless Router can act as a DHCP server.
Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP
client. This is the default Windows setting for the TCP/IP network protocol. How-
ever, Windows uses the term Obtain an IP Address automatically instead of
"DHCP Client".
You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If
your LAN does not have other Routers, this means there must only be one (1)
DHCP Server on your LAN.)
Using the Wireless Router's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this
screen, you can:
Enable or Disable the Wireless Router's DHCP Server function.
Set the range of IP Addresses allocated to PCs by the DHCP Server function.
The router will not accept a IP range of less than 10 IP’s. The IP range must be
equal or greater than 10 IP’s. Eg: 192.168.0.5 to 192.168.0.15.
You can assign Fixed IP Addresses to some devices
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another
DHCP Server, rather than the Wireless Router's, the following procedure is required.
1. Disable the DHCP Server feature in the Wireless Router. This setting is on the
LAN screen.
2. Configure the DHCP Server to provide the Wireless Router's IP Address as the
Default Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP under Windows 95/98/ME.
See Chapter 4 - Client Configuration for the procedure to check these settings.
