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.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.

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 also 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 "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.
Wireless Router User Guide
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.
•
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.
•
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 programs 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 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 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 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.
Introduction
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. 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 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.

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 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 (192.168.0.1) 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:

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 Screen section later in this chapter for details.
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.

TCP/IP
IP Address
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.
Subnet Mask
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).
DHCP Server
•
If Enabled, the Wireless Router will allocate IP Addresses 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 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. 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.

802.11 Mode
Select the desired option:
•
802.11g & 802.11b - This is the default, and should normally be
used.
•
802.11g 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.
•
Dynamic Super G (108Mbps) - This uses Packet Bursting,
FastFrame, Compression, and "Channel Bonding" (using 2 channels) to increase throughput. Only clients supporting the "Atheros
Super G" mode can connect at 108Mbps, and they will only use
this speed when necessary. However, this option is backwardcompatible with 802.11b and (standard) 802.11g.
•
Static Super G (108Mbps) - This uses Packet Bursting, FastFrame, Compression, and "Channel Bonding" (using 2 channels)
to increase throughput. Because "Channel Bonding" is always
used, this method is NOT compatible with 802.11b and (standard)
802.11g. Only clients supporting the "Atheros Super G" mode can
connect at 108Mbps; they will always connect at this speed. Select
this only if all wireless stations support the "Atheros Super G"
mode.
Channel
No
This field determines which operating frequency will be used. It should
not be necessary to change the wireless channel unless you notice

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.

Advanced Features
Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows
Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP address, your
IP address may change whenever you connect, which makes it difficult to connect to you.
The Service works as follows:
4. You must register for the service at one of the listed DDNS Service Providers.
5. After registration, follow the service provider's procedure to request a Domain Name and
have it allocated to you.
6. Enter your DDNS data on the Wireless Router's DDNS screen.
7. The Wireless Router will then automatically ensure that your current IP Address is recorded at the DDNS server.
If the DDNS Service provides software to perform this "IP address update"; you should
disable the "Update" function, or not use the software at all.
8. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)
using your Domain Name.
Dynamic DNS Screen
Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following:

Apply for a Domain Name, and ensure it is allocated to you.
•
Details of your DDNS account (Name, password, Domain name)
must then be entered and saved on this screen.
•
This device will then automatically ensure that your current IP
Address is recorded by the DDNS Service Provider. (You do
NOT need to use the "Client" program provided by some DDNS
Service providers.)
•
From the Internet, users will now be able to connect to your
Virtual Servers (or DMZ PC) using your Domain name.

Special Applications
If you use Internet applications which use non-standard connections or port numbers, you may
find that they do not function correctly because they are blocked by the Wireless Router's
firewall. In this case, you can define the application as a "Special Application".
Special Applications Screen
This screen can be reached by clicking the Special Applications button on the Internet screen.
You can then define your Special Applications. You will need detailed information about the
application; this is normally available from the supplier of the application.

Using a Special Application
•
Configure the Special Applications screen as required.
•
On your PC, use the application normally. Remember that only one (1) PC can use each
Special application at any time. Also, when 1 PC is finished using a particular Special Application, there may need to be a "Time-out" before another PC can use the same Special
Application. The "Time-out" period may be up to 3 minutes.
If an application still cannot function correctly,
try using the "DMZ" feature.
Multi-DMZ
This feature, if enabled, allows the DMZ computer or computers on your LAN to be exposed
to all users on the Internet.
•
This allows almost any application to be used on the "DMZ PC".
•
The "DMZ PC" will receive all "Unknown" connections and data.
•
If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".
If you have multiple Internet IP addresses, you can assign one DMZ PC for each Internet IP
address.
If you only have 1 WAN IP address, only "DMZ 1" can be used, and only one (1) PC can be
the DMZ PC. The current WAN IP address is displayed. If this address is assigned upon
connection, and no connection currently exists, then this address will be blank or 0.0.0.0.
59
Wireless Router User Guide
The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.
URL Filter
The URL Filter allows you to block access to undesirable Web site
•
To use this feature, you must define "filter strings". If the "filter string" appears in a
requested URL, the request is blocked.
•
Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination"
field in the log will display the URL. Otherwise, it will display the IP Address.

Virtual Servers
This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN
accessible to Internet users. Normally, Internet users would not be able to access a server on
your LAN because:
•
Your Server does not have a valid external IP Address.
•
Attempts to connect to devices on your LAN are blocked by the firewall in this device.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.
Figure 38: Virtual Servers
IP Address seen by Internet Users
Note that, in this illustration, both Internet users are connecting to the same IP Address, but
using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to
connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your
Virtual Servers using a URL, instead of an IP Address.

PC Database
The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It eliminates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your
LAN.
PC Database Screen
An example PC Database screen is shown below.

•
PCs which are "DHCP Clients" are automatically added to the database, and updated as
required.
•
By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called
"Obtain an IP Address automatically".
•
The Wireless Router uses the "Hardware Address" to identify each PC, not the name or IP
address. The "Hardware Address" can only change if you change the PC's network card or
adapter.
•
This system means you do NOT need to use Fixed (static) IP addresses on your LAN.
However, you can add PCs using Fixed (static) IP Addresses to the PC database if required.

Routing
Overview
•
If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
•
If the Wireless Router is only acting as a Gateway for the local LAN segment, ignore the
"Routing" page even if your LAN has other Routers.
•
If your LAN has a standard Router (e.g. Cisco) on your LAN, and the Wireless Router is
to act as a Gateway for all LAN segments, enable RIP (Routing Information Protocol) and
ignore the Static Routing table.
•
If your LAN has other Gateways and Routers, and you wish to control which LAN segments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure
the Static Routing table instead. (You also need to configure the other Routers.)
•
If using Windows 2000 Data center Server as a software Router, enable RIP on the Wireless Router, and ensure the following Windows 2000 settings are correct:
•
Open Routing and Remote Access
•
In the console tree, select Routing and Remote Access , [server name], IP Routing,
RIP
•
In the "Details" pane, right-click the interface you want to configure for RIP version
2, and then click "Properties".
•
On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and
Incoming packet protocol to "RIP version 1 and 2".
Routing Screen
The routing table is accessed by the Routing link on the Administration menu.
Using this Screen
Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing
Table, as explained above, although is it possible to use both methods simultaneously.
Static Routing Table
•
If RIP is not used, an entry in the routing table is required for each LAN segment on your
Network, other than the segment to which this device is attached.
•
The other Routers must also be configured. See Configuring Other Routers on your LAN
later in this chapter for further details and an example.

Configuring Other Routers on your LAN
It is essential that all IP packets for devices not on the local LAN be passed to the Wireless
Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this,
the local LAN must be configured to use the Wireless Router as the Default Route or Default
Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the Wireless Router. This
router requires that the Default Route is the Wireless Router itself. Typically, routers have a
special entry for the Default Route. It should be configured as follows.
Destination IP Address
Normally 0.0.0.0, but check your router documentation.
Network Mask
Normally 0.0.0.0, but check your router documentation.
Gateway IP Address
The IP Address of the Wireless Router.
Metric
Other Routers on the Local LAN
Other routers on the local LAN must use the Wireless Router's Local Router as the Default
Route. The entries will be the same as the Wireless Router's local router, with the exception of
the Gateway IP Address.
•
For a router with a direct connection to the Wireless Router's local Router, the Gateway IP
Address is the address of the Wireless Router's local router.
•
For routers which must forward packets to another router before reaching the Wireless
Router's local router, the Gateway IP Address is the address of the intermediate router.

Firewall
If enabled, DoS (Denial of Service) attacks will be detected and
blocked. The default is enabled. It is strongly recommended that this
setting be left enabled.
Note:
Threshold
•
A DoS attack does not attempt to steal data or damage your PCs,
but overloads your Internet connection so you can not use it - the
service is unavailable.
•
This device uses "Stateful Inspection" technology. This system can
detect situations where individual TCP/IP packets are valid, but
collectively they become a DoS attack.
This setting affects the number of "half-open" connections allowed.
•
A "half-open" connection arises when a remote client contacts the
Server with a connection request, but then does not reply to the
Server's response.
•
While the optimum number of "half-open" connections allowed
(the "Threshold") depends on many factors, the most important
factor is the available bandwidth of your Internet connection.

Appendix A
Troubleshooting
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using the Wireless
Router and some possible solutions to them. If you follow the suggested steps and the Wireless
Router still does not function properly, contact your dealer for further advice.
General Problems
Problem 1:
Can't connect to the Wireless Router to configure it.
Solution 1:
Check the following:
•
The Wireless Router is properly installed, LAN connections are OK,
and it is powered ON.
•
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.)
•
If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
•
If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the Wireless Router's default IP Address of 192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match the
Wireless Router.
In Windows, you can check these settings by using Control PanelNetwork to check the Properties for the TCP/IP protocol.
Internet Access
Problem 1:
When I enter a URL or IP address I get a time out error.
Solution 1:
A number of things could be causing this. Try the following troubleshooting
steps.
Problem 2:
•
Check if other PCs work. If they do, ensure that your PCs IP settings
are correct. If using a Fixed (Static) IP Address, check the Network
Mask, Default gateway and DNS as well as the IP Address.
•
If the PCs are configured correctly, but still not working, check the
Wireless Router. Ensure that it is connected and ON. Connect to it and
check its settings. (If you can't connect to it, check the LAN and power
connections.)
•
If the Wireless Router is configured correctly, check your Internet
connection (DSL/Cable modem etc) to see that it is working correctly.
Some applications do not run properly when using the Wireless Router.
87
Wireless Router User Guide
Solution 2:
The Wireless Router processes the data passing through it, so it is not
transparent.
Use the Special Applications feature to allow the use of Internet applications
which do not function correctly.
If this does solve the problem you can use the DMZ function. This should
work with almost every application, but:
•
It is a security risk, since the firewall is disabled.
•
Only one (1) PC can use this feature.
Wireless Access
Problem 1:
My PC can't locate the Wireless Access Point.
Solution 1:
Check the following.
•
Your PC is set to Infrastructure Mode. (Access Points are always in
Infrastructure Mode)
•
The SSID on your PC and the Wireless Access Point are the same.
Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup".
•
Both your PC and the Wireless Router must have the same setting for
WEP. The default setting for the Wireless Router is disabled, so your
wireless station should also have WEP disabled.
•
If WEP is enabled on the Wireless Router, your PC must have WEP
enabled, and the key must match.
•
If the Wireless Router's Wireless screen is set to Allow LAN access to
selected Wireless Stations only, then each of your Wireless stations
must have been selected, or access will be blocked.
•
To see if radio interference is causing a problem, see if connection is
possible when close to the Wireless Router.
Remember that the connection range can be as little as 100 feet in poor
environments.
Problem 2:
Wireless connection speed is very slow.
Solution 2:
The wireless system will connect at the highest possible speed, depending
on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following:
•
Wireless Router location.
Try adjusting the location and orientation of the Wireless Router.
•
Wireless Channel
If interference is the problem, changing to another channel may show a
marked improvement.
•
Radio Interference
Other devices may be causing interference. You can experiment by
switching other devices Off, and see if this helps. Any "noisy" devices
should be shielded or relocated.
•
RF Shielding
Your environment may tend to block transmission between the wireless
stations. This will mean high access speed is only possible when close
to the Wireless Router.
88
Appendix B
About Wireless LANs
This Appendix provides some background information about using Wireless
LANs (WLANs).
Modes
Wireless LANs can work in either of two (2) modes:
•
Ad-hoc
•
Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a
Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate
with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form
an Extended Service Set (ESS).
Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels.
As Wireless Stations are physically moved through the area covered by an ESS, they will
automatically change to the Access Point which has the least interference or best performance.
This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)
89
Wireless Router User Guide
Channels
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.
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have the same settings
for each of the following:
WEP
Off, 64 Bit, 128 Bit
Key
For 64 Bit encryption, the Key value must match.
For 128 Bit encryption, the Key value must match
WEP Authentication
Open System or Shared Key.
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point
must use the same settings, as follows:
Mode
On client Wireless Stations, the mode must be set to "Infrastructure".
(The Access Point is always in "Infrastructure" mode.)
SSID (ESSID)
Wireless Stations should use the same SSID (ESSID) as the Access
Point they wish to connect to. Alternatively, the SSID can be set to "any"
or null (blank) to allow connection to any Access Point.
WEP
The Wireless Stations and the Access Point must use the same settings
for WEP (Off, 64 Bit, 128 Bit).
WEP Key: If WEP is enabled, the Key must be the same on the Wireless Stations and the Access Point.
WEP Authentication: If WEP is enabled, all Wireless Stations must
use the same setting as the Access Point (either "Open System" or
"Shared Key").
