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 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 10BaseT Ethernet port for
connecting a DSL or Cable Modem. All popular DSL and Cable Modems are supported.
•
PPPoE and PPTP Support. The Internet (WAN port) connection supports PPPoE
(PPP over Ethernet) and PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct Connection" type services.
Wireless Router User Guide
•
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 Features
•
Standards Compliant. The Wireless Router complies with the IEEE802.11b (DSSS)
specifications for Wireless LANs.
•
WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit and
128 Bit keys are supported.
•
Access Control. The Access Control feature can 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.
Advanced Internet Functions
•
Conferencing & Telephony Applications. Internet Telephony and Conferencing
applications, which are often difficult to use when behind a Firewall, are supported.
•
Special Internet Applications. Applications that 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.
•
DMZ. 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 that 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.
•
VPN Support. VPN (Virtual Private Networking) connections using PPTP and IPSec are
transparently supported - no configuration is required.
LAN Features
•
4-Port Switching Hub. The Wireless Router incorporates a 4-port 10/100BaseTswitching 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 Router's RIP (Routing Information Protocol) support and built-in static routing table.
•
Network Printer. The printer attached to the Wireless Router becomes a "Network
Printer", available to all Windows and Linux (Unix) clients on your LAN.
Introduction
Configuration & Management
•
Easy Setup. Use your Web browser from anywhere on the LAN for configuration.
•
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.
•
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.
•
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
Configuration Program
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 Router. The PC and the Wireless
Router must be directly connected (using the Hub ports on the Router) or on the same
LAN segment.
•
The Wireless Router must be installed and powered ON.
•
If the Wireless Router's default IP Address (192.168.254.254) 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.
Connecting to the Wireless Router
Using UPnP
If your Windows operating 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 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:

Setup
If you can't connect
If the Router does not respond, check the following:
•
The Wireless Router is properly installed, LA N 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 192.168.254.254
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
192.168.254.1 to 192.168.254.253 to be compatible with the Wireless Router's default IP Address of 192.168.254.254. 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 segment.
(If you don't have a router, this must be the case.)

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 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.

Wireless Router User Guide
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.
16
Setup
Wireless Screen
The Wireless Access Point settings must match the other Wireless stations. To change the

SSID
(ESSID)
•
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.
•
Select the Channel you wish to use on your Wireless LAN.
•
If you experience interference (shown by lost connections and/or
slow data transfers) you may need to experiment with different
channels to see which is the best.

This Chapter details the PC Configuration required for each PC on the local
LAN.
Overview
For each PC, the following may need to be configured:
•
TCP/IP network settings
•
Wireless settings
•
Internet Access configuration
•
Printer configuration
Windows Clients
This section describes how to configure Windows clients for:
•
Internet access via the Wireless Router
•
Sharing the Printer connected to 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 t o the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must reconfigure the Router itself. Refer to Chapter 7 - Routing
for details.

There is no need to "Save" after each change; you can set the
destination PC for each application, then click "Save".
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.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the
client (PC) viewpoint

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.
DMZ
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the
Internet, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet
users or Servers.
•
This allows almo st 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".
•
The DMZ feature can be Enabled and Disabled on the Advanced Internet screen.
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.

Virtual Servers
This feature 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.

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.

Advanced Features
From the Internet, ALL Virtual Servers have the IP
Address allocated by your ISP.
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use
the Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.
However, you can use the Dynamic DNS feature, described in the following section, to allow
users to connect to your Virtual Servers using a URL, rather than an IP Address.
Dynamic DNS
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:
1.
You must register for the service at http://www.dyndns.org (Registration is free). Your
password will be E-mailed to you.
2.
After registration, use the "Create New Host" option (at www.dyndns.org) to request your
desired Domain name.
3.
Enter your data from www.dyndns.org in the Wireless Router's DDNS screen.
4.
The Wireless Router will then automatically ensure that your current IP Address is recorded at http://www.dyndns.org
5.
From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using
your Domain name, as shown on this screen.

Enable Remote
Management
Enable to allow management via the Internet. If Disabled, this device
will ignore management connection attempts from the Internet.
Port Number
Enter a port number between 1024 and 65535 (8080 is recommended).
This port number must be specified when you connect (see below).
Note: The default port number for HTTP (Web) connections is port
80, but using port 80 here will prevent the use of a Web "Virtual
Server" on your LAN. (See Advanced Internet - Virtual Servers)
Current IP Address
You must use this IP Address to connect (see below).
This IP Address is allocated by your ISP. But if using a Dynamic IP
Address, this value can change each time you connect to your ISP.
So it is better if your ISP allocates you a Fixed IP Address.
To connect from a remote PC via the Internet
1.
Ensure your Internet connection is established, and start your Web Browser.
2.
In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the Wireless
Router. If the port number is not 80, the port number is also required. (After the IP Address,
enter ":" followed by the port number.)
e.g.
HTTP://123.123.123.123:8080
This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080.

Wireless Router User Guide
Access Control
This feature is accessed by the Access Control link on the Advanced menu.
Overview
The Access Control feature allows administrators to restrict Internet Access by individual PCs.
With the default settings, everyone has unrestricted Internet access.
To use this feature:
1.
Set the desired restrictions on the "Default" group. All PCs are in the "Default" group
unless explicitly moved to another group.
2.
Set the desired restrictions on the other groups ("Group 1", "Group 2", "Group 3" and
"Group 4") as needed.
3.
Assign PCs to the groups as required.
Restrictions are imposed by blocking "Services", or types of
connections. All common Services are pre-defined.
If required, you can also define your own Services.

section of the "Advanced" menu.
Overview
Normally, it is not necessary to use these screens, or change any settings. These screens and
settings are provided to deal with non-standard situations, or to provide additional options for
advanced users.
The settings available are:
PC Database
This is the list of PCs shown when you select the "DMZ PC" or a
"Virtual Server". This database is maintained automatically, but you
can add and delete entries for PCs which use a Fixed (Static) IP
Address.
Options

PC Database Screen
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. An example PC Database screen is shown below.
Figure 41: PC Database Screen
•
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.

Network card or adapter. The address on the MAC Address screen is the address on the Internet (WAN port) interface, and has no effect on the LAN interface.
•
If your ISP asks for the "Network Adapter Address", "Physical Address", "Hardware
Address", or "MAC Address" for the PC the DSL/Cable modem is connected to, provide
this value.
•
If your ISP has already recorded a MAC address, you can change the address used by the
Wireless Router to match the address recorded by your ISP.

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 Advanced screen.
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
Enable DoS
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.
•
The Wireless Router 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.
•
Select the setting to match the bandwidth of your Internet connection.

The ICMP protocol is used by the "ping" and "traceroute" programs,
and by network monitoring and diagnostic programs.
•
If checked, the Wireless Router will repond to ICMP packets
received from the Internet.
•
If not checked, ICMP packets from the Internet will be ignored.
Disabling this option provides a slight increase in security.
The IPSec protocol is used to establish a secure connection, and is
widely used by VPN (Virtual Private Networking) programs.
•
If checked, IPSec connections are allowed.
•
If not checked, IPSec connections are blocked.
PPTP (Point to Point Tunneling Protocol) is widely used by VPN (Virtual Private Networking) programs.
•
If checked, PPTP connections are allowed.
•
If not checked, PPTP connections are blocked.
L2TP is a protocol developed by Cisco for VPNs (Virtual Private Networks).
•
If checked, L2TP connections are allowed.
•
If not checked, L2TP connections are blocked.

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. Check the LEDs for port status.
•
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 192.168.254.1 to 192.168.254.253 and thus compatible with the Wireless Router's default IP Address of 192.168.254.254.
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.
80
Appendix A - Troubleshooting
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 for the DMZ PC.
•
Only one (1) PC can use this feature.
Printing
Problem 1:
When I tried to install the Printing software for Peer-to-Peer printing, I
received an error message and the installation was aborted..
Solution 1:
This may be caused by an existing installation of the printer port software.
Before attemp ting another installation:
•
Remove the existing installation
•
Restart your PC
To remove an existing printer port installation:
1.
Open Start - Settings - Control Panel - Add/Remove Programs
2.
Look for an entry with a name like "Shared Port", "Shared Printer Port",
"Print Server Driver" or "Print Server Port".
3.
Select this item, click "Add/Remove", and confirm the deletion.
Problem 2:
I am using Windows 95, and the Printing software installed and ran, but
when I selected a port on a Wireless Router and clicked "Add", the
printer was not installed.
Solution 2:
Try installing the printer using the standard Windows tools, as follows:
1.
Start the Add Printer Wizard.
2.
Select Network Printer when prompted "How is the printer attached to
your Computer?", and click Next.
3.
When prompted for the Network Path or Queue, enter a dummy value
such as \\123, as shown below. (Do NOT select Yes for "Do you print
for MS-DOS programs?")
81
Wireless Router User Guide
4.
The printer wizard will display a message stating that "The Network
Printer is off-line". This is OK. Continue the Add Printer Wizard until
finished.
5.
When finished, go to Control Panel-Printers. The printer icon will be
grayed out indicating the printer is not ready.
6.
Right-click the Printer, and select Properties. Then select the Details
tab, as shown below.
7.
Click the Add Port button. On the resulting screen, select Other, then
Shared Port, as the port to add, as shown below.
82
Appendix A - Troubleshooting
8.
Click OK to see the Print Port Configuration screen, as shown below.
9.
Click the Browse Device button, select the device name of the desired
Wireless Router, and click OK.
10. Click OK to return to the Printers folders, and right-click on the Printer.
Ensure that the Work off-line option is NOT checked.
The Printer should no longer be grayed out, and is ready for use.
