Regulatory Approvals
FCC Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
Consult the dealer or an experienced radio/TV technician for help.
To assure continued compliance, any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate this equipment.
(Example - use only shielded interface cables when connecting to computer or peripheral
devices).
FCC Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause
undesired operation.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
The antennas used for this transmitter must be installed to provide a separation distance of at
least 20 cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter.
Channel
The Wireless Channel sets the radio frequency used for communication.
•Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent
Access Points use different Channels to reduce interference.
• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest
signal is used. (This can only happen within an ESS.)
• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
Note:This equipment marketed in USA is restricted by firmware to only operate on 2.4G channel 1-11

•
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
• TShared Internet Access.T 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).
TDSL & Cable Modem Support.T 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 also included.
TPPPoE, 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 "Direct Connection"
type services. Unnumbered IP with PPPoE is also supported.
T

Wireless Router User Guide
TFixed or Dynamic IP Address.T 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 TApplications.T 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.
•
Special TInternet Applications.T 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.
TVirtual Servers.T This feature allows Internet users to access Internet servers on your
•
LAN. The required setup is quick and easy.
•
TDDNS Support.T 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.
•
TMulti-DMZ.T 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 ru n programs which are
incompatible with Firewalls.
TURL Filter.T Use the URL Filter to block access to undesirable Web sites by LAN users.
•
TInternet Access Log.T See which Internet connections have been made.
•
TAccess Control.T Using the Access Control feature, you can assign LAN users to
•
different groups, and determine which Internet services are available to each group.
•
TVPN Pass through Support.T PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
Wireless Features
• TStandards Compliant.T The Wireless Router complies with the IEEE802.11g (DSSS)
specifications for Wireless LANs.
•
TSupports both 802.11b and 802.11g Wireless Stations.T 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.
TSpeeds to 54Mbps.T All speeds up to the 802.11g maximum of 54Mbps are supported.
•
TWEP support.T Support for WEP (Wired Equivalent Privacy) is included. Key sizes of
•
64 Bit and 128 Bit are supported.
•
TWPA support.T The WPA-PSK (Pre-shared Key) standard provides greater security for
your Wireless clients than WEP.
•
TWPA2 support.T The WPA2 (Pre-shared Key) standard, a later version of WPA which
offers improved security. AES encryption is always used.
•
TWPA+WPA2 support.T If selected, wireless clients may use either WPA or WPA2. This
option is sometimes called "Mixed Mode".
Wireless MAC-level 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.
T

Introduction
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 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
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. WPA-PSK and WEP (Wired Equivalent Privacy) are
supported, as well as MAC-level 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 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.
Stateful Inspection Firewall. All incoming data packets are monitored and all
•
incoming server requests 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 unavailable. The Wireless
Router incorporates protection against DoS attacks.

Wireless Router User Guide
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 192.168.0.1
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 details 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 settings.

IP address for the Wireless Router, as seen from the local LAN. 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.
The default value 255.255.255.0 is standard for small (class "C")
networks. For other networks, use the Subnet Mask for the LAN
segment to which the Wireless Router is attached (the same value as
the PCs on that LAN segment).
• If Enabled, the Wireless Router will allocate IP Addr esses to PCs
(DHCP clients) on your LAN when they start up. The default (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 Gateway. 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 Addresses to DHCP
clients. This range also determines the number of DHCP clients
supported.
See the following section for further details on using DHCP.

Setup
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, Windows 2000 and Windows XP act as a DHCP client. This is the
default Windows setting for the TCP/IP network protocol. However, 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.
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.

Mode
• If using an ESS (Extended Service Set, with multiple access
points) this ID is called an ESSID (Extended Service Set
Identifier).
• To communicate, all Wireless stations should use the same
SSID/ESSID.
• If Enabled, wireless stations will be able to locate an d use this
Access Point.
• If Disabled, the wireless interface is disabled, and will neither
transmit nor receive wireless traffic.
• The Wireless (WLAN) LED on the front panel will remain OFF if
the Wireless interface is disabled.
If Enabled, the SSID will broadcast its name to all Wireless Stations.
Stations which have no SSID (or a "null" value) can then adopt the
correct SSID for connections to this Access Point.
Select the desired option:
• g & b - This is the default, and should normally be used.
• g only - If selected, this ensures that "g" mode stations will
connect at high speed, but "b" mode stations will be unable to
connect at all.
• b only - If selected, "g" mode is unavailable. "g" mode stations
will only be able to connect if they are fully backward-compatible
with "b" mode.

Wireless Security
This screen is accessed by clicking the "Configure" button on the Wireless screen. There are 3
options for Wireless security:
• Disabled - no data encryption is used.
• WEP - data is encrypted using the WEP standard.
• WPA - data is encrypted using th e WPA-PSK standard. This is a later standard than WEP,
and provides much better security than WEP. If all your Wireless stations support WPAPSK, you should use WPA-PSK rather than WEP.
• WPA2 - data is encrypted always using the AES (Advanced Encryption Standard). This is
a later version of WPA which offers improved security.
• WPA+WPA2 - data is encrypted using either WPA-PSK or WPA2-PSK standard. This
option is sometimes called "Mixed Mode"
•

WEP
The 802.11b standard. Data is encrypted before transmission, but the
encryption system is not very strong.
Normally this can be left at the default value of "Auto". If that fails,
select the appropriate value - "Open System" or "Shared Key." Check
your wireless station's documentation to see what method to use.
Select the WEP Encryption level:
• 64-bit (sometimes called 40-bit) encryption
• 128-bit (sometimes called 104 bit) encryption
All wireless stations must use the same key values as the Wireless
Router.

Setup
• Use the radio buttons to select the default key.
• Enter the key value you wish to use. Other stations must have the
same key values.
• Keys must be entered in Hex.
Hex characters are the digits (0 ~ 9) and the letters A ~ F.
Passphrase
This feature allows you to generate a key or keys from a text (ASCII)
phrase, rather than enter keys in Hex.
To use this feature:
• Enter a word or group of printable characters in the Passphrase
field
• Click the "Generate Key" button.
• If encryption strength is set to 64 bit, then each of the four key
fields will be populated with key values. If encryption strength is
set to 128 bit, then only the selected WEP key field will be given a
key value.
WPA Wireless Security
If "WPA" is selected, the screen will look like the following example.

WPA
Like WEP, data is encrypted before transmission. WPA is more
secure than WEP, and should be used if possible. WPA is the version
of WPA, which does NOT require a Radius Server on your LAN.
Enter the Keyword key value. Data is encrypted using a key derived
from the network key. Other Wireless Stations must use the same
network key. The PSK must be from 8 to 63 characters in length.
This determines how often the encryption key is changed. You can
change the default value if desired.
The WPA standard allows different encryption methods to be used.
Select the desired option. Wireless Stations must use the same
encryption method.

Chapter 4
PC Configuration

This Chapter details the PC Configuration required on the local ("Internal")
LAN.
Overview
For each PC, the following may need to be configured:
• TCP/IP network settings
• Internet Access configuration
• Wireless configuration
Windows Clients
This section describes how to configure Windows clients for Internet access via the Wireless
Router.
The first step is to check the PC's TCP/IP settings.
The Wireless Router uses the TCP/IP network protocol for all functions, so it is essential that
the TCP/IP protocol be installed and configured on each PC.
TCP/IP Settings - Overview
If using the default Wireless Router settings and the default Windows
TCP/IP settings, no changes need to be made.
• By default, the Wireless Router will act as a DHCP Server, automatically providing a
suitable IP Address (and related information) to each PC when the PC boots.
• For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP
client.
If using a Fixed (specified) IP address, the following changes are
required:
• The Gateway must be set to the IP address of the Wireless Router
• The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must reconfigure the Router itself. Refer to Chapter 8 -
Advanced Setup for details.

Wireless Router User Guide
Checking TCP/IP Settings - Windows 9x/ME:
1. Select Control Panel - Network. You should see a screen like the following:
Figure 14: Network Configuration
2. Select the TCP/IP protocol for your network card.
3. Click on the Properties button. You should then see a screen like the following.
Figure 15: IP Address (Win 95)
Ensure your TCP/IP settings are correct, as follows:
Using DHCP
To use DHCP, select the radio button Obtain an IP Address automatically. This is the default
Windows setting. Using this is recommended. By default, the Wireless Router will act as a
DHCP Server.
Restart your PC to ensure it obtains an IP Address from the Wireless Router.
Using "Specify an IP Address"
If your PC is already configured, check with your network administrator before making the
following changes:
