Wireless Gateway Features
The Wireless Gateway incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
LAN Features
•
•
Dual LAN ports. The Wireless Gateway has two (2) 10/100BaseT Ethernet LAN ports.
Normally, the “Hub” port is used to connect the Wireless Gateway to a 10/100BaseT hub
on your LAN. But if desired, the “PC” port can be used to connect the Wireless Gateway
directly to your PC, using a standard LAN cable.
DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Wireless Gateway can act as a DHCP
Server for devices on your local LAN and WLAN.

Wireless Gateway User Guide
•
Multi Segment LAN Support. LANs containing one or more segments are supported,
via the Wireless Gateway's built-in static routing table. If NAT (Network Address Transla-
tion) is disabled, the Wireless Gateway will function as a static router.
Internet Access Features
•
Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Wireless Gateway, using only a single external IP Address. The local (invalid)
IP Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).
•
•
DSL & Cable Modem Support. The Wireless Gateway has a 10BaseT Ethernet port
for connecting an DSL or Cable Modem. All popular DSL and Cable Modems are sup-
ported.
Analog Modem and ISDN TA Support. If you don't yet have Broadband Internet
access, the Wireless Gateway can provide shared Internet access via an analog modem or
ISDN TA connected to the serial (RS232) port.
•
•
PPPoE Support. The WAN port connection can use PPPoE (PPP over Ethernet), if your
ISP uses this method.
Fixed or Dynamic IP Address. On the WAN connection, the Wireless Gateway
supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP
Address.
Wireless Features
•
•
•
Standards Compliant. The Wireless Gateway complies with the IEEE802.11b (DSSS)
specifications for Wireless LANs.
Security Features. Support for WEP (Wired Equivalent Privacy) and Access Control is
included.
Simple Configuration. If the default settings are unsuitable, they can be changed
quickly and easily.
Network Printer
•
Share your Printer. A printer connected to the Wireless Gateway's parallel port can be
used by all PCs on the LAN.
•

Advanced Internet Functions
•
•
•
•
•
•
Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
User-Defined Virtual Servers. Internet users can access non-standard Internet Servers
on your LAN by using this feature.
Special Internet Applications. Internet applications such as Internet Videoconferenc-
ing, Telephony, Games Servers, and other special-purpose Servers are supported.
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.
URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users,
Wireless LAN users, or the Dial-in user.
Internet Access Log. See which Internet connections have been made.
RAS (Remote Access Services)
•
RAS Dial-in. Remote PC users can use their standard Dial-up software to connect to the
Wireless Gateway and access LAN resources.
•
Dial-back Support. For additional security, the Dial-back feature can be used to hang up
and re-dial the remote user. Both fixed and roaming options are supported.
Configuration & Management
•
•
Easy Setup. Use your WEB browser from anywhere on the LAN for configuration.
Remote Management. The Wireless Gateway can be managed from any PC on your
LAN. And, if the Internet connection exists, it can also (optionally) be configured via the
Internet.
Security Features
•
Configuration Data. Optional password protection is provided to prevent unauthorized
users from modifying the configuration.
•
Access Control Features. The LAN Administrator can limit Internet access by individ-
ual workstations. And the Access Control log allows the Administrator to see attempted
accesses which have been blocked.
•
•
Wireless LAN Security. WEP (Wired Equivalent Privacy) is supported, as well as
Wireless access control via station address.
Firewall Protection. All incoming data packets are monitored and all incoming server
requests are filtered, thus protecting your network from malicious attacks from external
sources. (This protection is lost if NAT is disabled.)

Wireless Gateway User Guide
NAT Firewall Protection
The firewall protection provided by the Wireless Gateway is an intrinsic side effect
of NAT (Network Address Translation). All users on the LAN share a single
external IP address. From the external viewpoint, there is no network, only a single
device.
For internal users, the Wireless Gateway acts as a “transparent proxy server”,
translating the multiple internal IP addresses into a single external IP address.
For external requests, any attempt to connect to local resources is blocked. The
Wireless Gateway will not “reverse translate” from a external IP address to a local
IP address.
This type of “natural” firewall provides an impregnable barrier against malicious
attacks.

The Wireless Gateway contains an HTTP server. This enables you to connect to it, and config-
ure it, using your Web Browser.
Most Browsers should work, provided they support HTML tables and forms.
Preparation
Before attempting to configure the Wireless Gateway, please ensure that:
•
Your PC can establish a physical connection to the Wireless Gateway. The PC and the
Wireless Gateway must be directly connected (using the “PC” port on the Wireless Gate-
way) or on the same LAN segment.
•
•
The Wireless Gateway must be installed and powered ON.
If the Wireless Gateway's default IP Address (192.168.0.1) is already used by another
device, the other device must be turned OFF until the Wireless Gateway is allocated a new
IP Address during configuration.
Connecting to the Wireless Gateway
To establish a connection from your PC to the device:
1. After installing the Wireless Gateway in your LAN, start your PC. If your PC is already
running, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the Wireless Gateway, as in this
example, which uses the Wireless Gateway’s default IP Address:
HTTP://192.168.0.1
4. You should then see the Quick Setup screen.

cryption will fail.
The easiest way to ensure there are no problems is to have
every Station, including the Access Point, use the same key ta-
ble (all entries identical). Then, it does not matter which key is
used as the default key.

•
•
•
Internet access via the Wireless Gateway
Printing using the printer attached to the Wireless Gateway.
Remote Dial-in access to the modem attached to the Wireless Gateway's serial (RS232)
port.
The first step is to check the PC's TCP/IP settings.
The Wireless Gateway 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
If using the default Wireless Gateway settings, and the default Windows 95/98 TCP/IP
settings, no changes need to be made.
•
By default, the Wireless Gateway will act as a DHCP Server, automatically providing a
suitable IP Address to each PC when the PC boots.
•
The default Windows 95/98 TCP/IP setting is to act as a DHCP client.
To check your PC's TCP/IP Settings:
1. Select Control Panel - Network. You should see a screen like the following:

This section applies to all Wireless stations wishing to use the Wireless Gateway's Access
Point, regardless of the operating system which is used on the client.
To use the Wireless Access Point in the Wireless Gateway, each Wireless Station must have
compatible settings, as follows:
Mode
The mode must be set to Infrastructure.
This must match the value used on the Wireless Gateway. The default
SSID (ESSID)
value is default
Note! The SSID is case sensitive.
WEP
By default, WEP on the Wireless Gateway is disabled.
•
If WEP remains disabled on the Wireless Gateway, all stations must
have WEP disabled.
•

Chapter 5
DHCP
5
This Chapter covers the use of DHCP, using either an existing DHCP Server
or the Wireless Gateway's DHCP Server function.
Overview
If your LAN does not use DHCP, and you do not wish to use DHCP, you can ignore this
chapter.
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 boots.
The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.
•
•
Windows 95/98/ME include all the software required to act as a DHCP client. This is the
default Windows setting for TCP/IP. However, Windows uses the term Obtain an IP Ad-
dress automatically instead of "DHCP Client".
The Wireless Gateway can act as a DHCP server.
Using the Wireless Gateway'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 Gateway'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. If you wish to use another DHCP Server, rather than
the Wireless Gateway’s, the following procedure is required.
1. Disable the DHCP Server feature in the Wireless Gateway. This setting is on the LAN
screen.
2. Configure the DHCP Server to provide the Wireless Gateway’s IP Address as the Default
Gateway.

This Chapter details using the Serial (RS232) Port, either for Internet Access
or Dial-in use.
Overview
The Serial (RS232) port can be used for Internet Access or to provide RAS (Dial-in) access to
your LAN.
•
•
If used for Internet access, the WAN (Ethernet) Port cannot be used.
Both Internet Access and Dial-in Access can be enabled simultaneously, but if the modem
is in use, a Dial-in user will only get a "busy" signal on their telephone line.

PPP Link
•
PAP has widespread support; almost all communications systems
support it.
•
CHAP is more secure than PAP; the password is encrypted before
transmission. If it is selected, the dial-in clients must also support CHAP
in order to connect.
•
•
MS CHAP is the Microsoft version of CHAP, used on Windows
platforms. If all dial-in clients are using Windows 95 or later, you can
choose this option.
None means no login authentication is performed.
Warning! If you choose "None", anyone can connect; this is a major
security risk.

Dial -in Users
This section describes how to create and manage remote users who wish to use the Wireless
Gateway's RAS Dial-in facility.
For details of configuring the remote PC to use Dial-in access, refer to Dial-in in Chapter 4 -
Client PC Configuration.
Overview
Upon connection, the Wireless Gateway will allocate an IP Address to the Dial-in user. To
other LAN users and devices, the Dial-in user will be valid device on the LAN. However,
currently Microsoft networking services are not available.
•
The Dial-in user can connect to any Servers and devices on your LAN which use the
TCP/IP network protocol. For example, the Dial-in user can connect to an E-Mail Server,
Web Server, or FTP Server on your LAN. If a PC is running NetMeeting, PC Anywhere or
similar program, the Dial-in user can connect to that PC.
•
•
The Dial-in user can use access the Internet through the Wireless Gateway, just like LAN
users.
The Dial-in user can print to the printer connected to the Wireless Gateway, just as if they
were on the LAN.
Controlling Dial-in Access
The Wireless Gateway provides the following options to control Dial-in access:
1. Allow access by anyone and everyone.
•
If Dial-in PPP link security on the Serial Port screen is set to "None", then the user
name and password is not checked, so anyone who dials in can gain access.
•
This creates a major security weakness. It is strongly recommended that this option is
NOT used.
2. All users use the same log-in.
•
All Dial-in users can use the existing "guest" user, once Dial-in access is Enabled for
both the Serial port and the guest user.
•
A password should be assigned to the "guest" user. By default, there is no password.
3. Each Dial-in user has a separate log-in and password
•
•
This is the recommended approach.
Each person requiring dial-in access is entered in the Wireless Gateway's user data-
base, using the Dial-in Users and User Details screens.

If desired, enter any other DNS IP Addresses here. The first available DNS will be used.
NAT (Network Address Translation)
NAT allows PCs on your LAN to share a single external (Internet) IP Address. This IP Address
is supplied by your ISP. Use the following to determine whether or nor you need NAT.
•
•
•
For Internet access, NAT must be left On unless all PCs on your LAN have valid external
IP Addresses.
If this device is not being used to provide shared Internet access, NAT is not normally
required. With NAT disabled, the Wireless Gateway will act as a static router.
If NAT is disabled, the Firewall protection provided by the Wireless Gateway is lost, and
the Advanced Internet features (Virtual Servers, Special Applications, and DMZ) are no
longer available.

Port Number
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)
You must use this IP Address to connect (see below).
Current IP Address
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.

Chapter 8
Routing
8
This Chapter explains the Routing features of the Wireless Gateway.
Overview
•
•
•
If you don't have other Routers or Gateways on your LAN, ignore the "Routing" page
completely.
If the Wireless Gateway 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 Gateway 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 seg-
ments 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 Datacenter Server as a software Router, enable RIP on the Wire-
less Gateway, 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 Options screen.
Using this Screen
Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table,
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 Router Configuration later in this chapter for
further details and an example.

Router Configuration
It is essential that all IP packets for devices not on the local LAN be passed to the Wireless
Gateway, 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 Gateway as the Default Route or
Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the Wireless Gateway.
This router requires that the Default Route is the Wireless Gateway itself. Typically, routers
have a special entry for the Default Route. It should be configured as follows.
Normally 0.0.0.0, but check your router documentation.

Other Routers on the Local LAN
Other routers on the local LAN must use the Wireless Gateway's Local Router as the Default
Route. The entries will be the same as the Wireless Gateway's local router, with the exception
of the Gateway IP Address.
•
For a router with a direct connection to the Wireless Gateway's local Router, the Gateway
IP Address is the address of the Wireless Gateway's local router.
•
For routers which must forward packets to another router before reaching the Wireless
Gateway's local router, the Gateway IP Address is the address of the intermediate router.

Wireless Gateway User Guide
URL Filter
The URL Filter provides a means to block access to undesirable Web sites. The blocking action
applies to all PCs accessing the Internet via the Wireless Gateway.
Operation
The URL Filter feature works by matching the "Filter Strings" (text strings) against the re-
quested URL. For example, by inputting the word “bad” in the URL Filter, any URL containing
the letters “bad” in it will be blocked.
Note that if any component of the URL request contains one of the "Filter Strings", that
request will be blocked while the URL Filter is enabled.
URL requests to Web (Internet) Servers include the following components:
•
Protocol. For Internet access, the usual protocol is HTTP (shown in your browser as
"HTTP://"). The URL Filter works ONLY with the HTTP protocol. Other protocols, such
as FTP and E-Mail, are not affected by the URL Filter.
•
•
•
Domain. This is the address of the site (e.g. www.microsoft.com)
Path. This specifies a certain file on the Server (e.g. /public/docs/index.html )
Parameters. This is the data which is sent (submitted) to the Server when you submit a
form, such as when you use a search engine to search the Internet.
On a Web page, clicking a link may also submit data to a Server, rather than just request a
file.
All of these components are searched to see if they contain any of the "Filter Strings".
Tips
•
To use the URL Filter feature properly, you should try inputting as much of the text for the
given URL as possible. For example, instead of simply using the word “bad,” you could
use the full web site name.
•
•
•
If you do not want to block an entire web site, you can include the path rather than just the
domain. For example, “www.badsite.com/badsection/”
Be careful when using the URL Filter, as a general word might block access to many other
sites as well as the one that you intend to block.
You can use the Internet Access Log, accessed from the Status screen, to see which sites
have been blocked by the URL Filter.

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.
Figure 31: 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 con-
nect to your Servers. If using a Static IP Address, it is entered on the "WAN" screen.
Types of Virtual Servers
The Wireless Gateway supports two (2) types of Virtual Servers:
•
Pre-defined - Standard server types. The only data required is the IP Address of the server
on your LAN.
•
User-defined - Non-standard servers. You must provide additional information about the
server.
Note: The TOTAL number of Virtual Servers which can be used at any time is 10.

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 connection to special-purpose servers which require proprietary client software, or
2-way user connections such as Video-conferencing, which requires both users to run special
software.
To allow unrestricted access, the Firewall in
this device is disabled, creating a security
risk.
You should use this feature only if the "Special Applications" feature is insuffi-
cient to allow an application to function correctly. This feature should be turned
ON only when needed, and left OFF the rest of the time.

Chapter 10
Access Control
10
This Chapter explains how to configure and use the Wireless Gateway's "Ac-
cess Control" feature.
Overview
The Access Control feature allows administrators to restrict Internet Access by individual PCs.
The process uses "Packet Filtering" to block or discard data packets. By default, no packets are
blocked or discarded.
To use this feature:
•
Set the desired restrictions on the "Everyone" group. All PCs are in the "Everyone" group
unless explicitly moved to another group, using the PC screen.
•
•
Set the desired restrictions on the other groups ("Group 1", "Group 2", etc) as needed.
For each PC you wish to move from the "Everyone" group, enter their details on the PCs
screen, and assign them to the desired group.
You can limit Internet access for ALL PCs without
entering ANY PC data. Simply apply the desired
restrictions to the "Everyone" group.
It is also possible to define your own packet filters, and use these filters in addition to the pre-
defined filters. Defining your own filters is optional.
Access Control Log
This log is accessed from the Access Control Log on the Status screen. It shows the attempted
accesses which have been blocked.
This log can be used to track the operation of the Access Control feature. Data shown in this
log is as follows:
•
•
•
•
Port - The port used to gain access to this device. Possible values are LAN, WAN, WLAN
(Wireless LAN), and RS232 (serial port).
Source IP Address - The IP Address of the PC or device whose access request was
blocked.
Physical Address (Hardware Address) - The hardware address of the PC or device
whose access request was blocked.
Name - If known, the name of the device whose access was blocked. This name is taken
from the Access Control database. For Wireless devices, the name is obtained from the
Wireless Stations list, and so will always match the Physical (Hardware) address.
•
Destination - The destination of the attempted access. Possible values are "Internet",
"LAN" or "WLAN".
•
"Internet" indicates an outgoing connection attempt which was blocked by the Access
Control feature.
•
"LAN" or "WLAN" represents an inward connection attempt which was blocked by
the Firewall. These inward connection attempts are not affected by the Access Control
settings.

Appendix A
Troubleshooting
A
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
Gateway and some possible solutions to them. If you follow the suggested steps and the Wire-
less Gateway still does not function properly, contact your dealer for further advice.
General Problems
Problem 1:
Can’t connect to the Wireless Gateway to configure it.
Check the following:
Solution 1:
•
•
•
The Wireless Gateway is properly installed, LAN connections are OK,
and it is powered ON.
Ensure that your PC and the Wireless Gateway are on the same network
segment. (If you don't have a router, this must be the case.)
Ensure that your PC is using an IP Address within the range 192.168.0.2
to 192.168.0.254 and thus compatible with the Wireless Gateway's de-
fault IP Address of 192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match the
Wireless Gateway.
In Windows, you can check these settings by using Control Panel-
Network 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.
A number of things could be causing this. Try the following troubleshooting
steps.
Solution 1:
•
Check if other PCs work. If they do, ensure that your PCs IP settings are
correct (IP address, Network Mask, Default gateway and DNS).
•
If the PCs are configured correctly, but still not working, check the
Wireless Gateway. 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 Gateway is configured correctly, check your Internet
connection (DSL/Cable modem etc) to see that it is working correctly.
Problem 2:
Some applications do not run properly when using the Wireless Gate-
way.
The Wireless Gateway processes the data passing through it, so it is not
transparent.
Solution 2:
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.
When the DMZ feature is being used, the Special Applications and
Virtual Server features should be disabled.
Wireless Access
Problem 1:
My PC can't locate the Wireless Access Point.
Check the following.
Solution 1:
•
•
Your PC is set to Infrastructure Mode.
The wireless channel used matches the wireless channel on the Access
Point.
•
•
The SSID on your PC and the Wireless Access Point are the same.
Remember that the SSID is case-sensitive. So, for example "Work-
group" does NOT match "workgroup".
Both your PC and the Wireless Access Point must have the same setting
for WEP. The default setting for the Wireless Gateway is disabled, so
your wireless station should also have WEP disabled.
•
•
If WEP is enabled, the key tables must match.
If the Wireless Station access permission on the Wireless Gateway's
Wireless screen is set to Only allow access if on this list, then each
Wireless station must have its address correctly entered.
•
To see if radio interference is causing a problem, see if connection is
possible when close to the Wireless Access Point.
Remember that the connection range can be as little as 100 feet in poor
environments.
Problem 2:
Wireless connection speed is very slow.
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:
Solution 2:
•
Access Point location.
Try adjusting the location and orientation of the Access Point.
•
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 Access Point.

Appendix A - Troubleshooting
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.
This may be caused by an existing installation of the printer port software.
Before attempting another installation:
Solution 1:
•
•
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 and clicked "Add"; the printer was not
installed.
Try installing the printer using the standard Windows tools, as follows:
Solution 2:
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?")
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.
83

9. Click the Browse Device button, select the desired Wireless Gateway,
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.
Problem 3:
On my Macintosh, the Wireless Gateway's printer is not listed.
Check the following:
Solution 3
•
Ensure the network connection is working. If you can connect to the
Wireless Gateway for configuration, then the connection is OK.
•
Ensure the Printer Object Type on the Wireless Gateway's Printer
Port screen is set correctly. If this is wrong, the printer will not be
listed on the Macintosh. Check your printer manufacturer's documen-
tation or Web site to determine the correct Object Type for your
printer.

Dial-in Access
Problem 1:
Remote PC can't connect to the Wireless Gateway.
Check the settings on the Wireless Gateway
Solution 1:
•
•
•
•
•
•
Serial Port is Enabled.
Dial-in is Enabled.
User has been created, and has Dial-in permission.
Call-back settings are correct for this user.
Modem settings are correct.
Both the Wireless Gateway and the remote PC are using the same
settings for the login authentication (PAP, CHAP, MSCHAP).
Check the Modem
•
•
Modem is properly connected and powered on.
The modem is working correctly, and the Remote user is dialing the
correct telephone number for the modem.
This can be checked by listening to the modem. You should hear the
Wireless Gateway's modem answer the incoming call.
•
If the call is received but not answered, the modem's "Auto-
answer" feature is turned OFF. To turn it on, add the appropriate
AT command to the Initial String in the on the Wireless Gate-
way's Modem Properties screen. See Chapter 6 for details of the
Modem Properties screen, and Appendix C for more information
on AT commands.
•
If the call is answered, but no connection is established, then ei-
ther the modems are unable to negotiate a connection, or the login
to the Wireless Gateway has failed.
This can be checked by examining the Log file for the Remote
PC. See Finding the current Initial String in Appendix C for in-
structions on enabling and viewing the Log file.
Check the Remote PC
•
•
•
Ensure that both the Wireless Gateway and the remote PC are using
the same settings for the login authentication (PAP, CHAP,
MSCHAP).
When prompted for "User Name" and "Password", the remote user
must enter the correct User Name and Password, as configured on the
Wireless Gateway's User Details screen.
The modem Log file on the remote PC may provide useful information
about the cause of the connection failure. See Finding the current Ini-
tial String in Appendix C for instructions on enabling and viewing the
Log file.
Problem 2:
Remote PC can connect using Dial-in, but can't access LAN resources.
Currently, Microsoft networking (using NetBIOS over TCP/IP) is not
supported. Only standard TCP/IP connections can be made. So the Dial-in
PC cannot use Network Neighborhood, or Windows File/Print sharing.

Appendix A - Troubleshooting
Problem 3:
On the LAN, there is an IP Address conflict involving the Dial-in PC.
How do I set the IP Address allocated to the Dial-in PC?
This problem can only occur if the Wireless Gateway's DHCP Server is
Disabled.
Answer 3:
In this situation, the DHCP Server must still allocate an IP Address to the
Dial-in user. To set this IP Address:
1. Connect to the Wireless Gateway
2. On the Quick Setup screen, locate the DHCP Server section, and set
both the Start IP Address and the Finish IP Address to the IP Address
you wish to be assigned to the Dial-in user.
3. Save these settings.

Appendix B
About Wireless LANs
B
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 Sta-
tions (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 interfer-
ence, 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 capabili-
ties.)
88

Appendix B - About Wireless LANs
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.
Client (PC) 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 your PC's wireless card does NOT automatically scan all wireless channels, then you
must manually set it to the Channel used on the Access Point.
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:
Off, 64 Bit, 128 Bit
WEP
Key
For 64 Bit encryption, the Key Table must match.
For 128 Bit encryption, the Key value must match.
Open System or Shared Key.
WEP Authentication

Wireless Gateway User Guide
Access Control
The Access Control feature allows you to determine which Wireless Stations can use the
Access Point. You need to identify each Wireless Station by its Hardware or physical Address.
On Windows, you can determine the Hardware (physical) Address using WinIPCfg, as follows:
1. Use Start - Run to open the "Run" dialog.
2. Type WINIPCFG and press Enter (or click OK).
Figure 38: WinIpCfg
3. WinIPCfg will then run, as shown above.
4. Select your Wireless adapter from the drop-down list, and check the Adapter Address field.
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:
On client Wireless Stations, the mode must be set to "Infrastructure".
(The Access Point is always in "Infrastructure" mode.)
Mode
Wireless Stations must use the same SSID (ESSID) as the Access Point
they wish to connect to.
SSID (ESSID)
WEP
The Wireless Stations and the Access Point must use the same settings
for WEP (Off, 64 Bit, or 128 Bit).
WEP Key: If WEP is enabled, the Key Table (for 64 Bit encryption) or
Key (for 128 Bit Encryption) 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").

C
AT Commands
This Appendix details the "AT" commands used by modems and ISDN TAs. This information
is provided to assist users who are using the Wireless Gateway's serial (RS232 port).
It is not relevant to Cable or DSL modems connected to the WAN (Ethernet) port.
Required Settings
For the Wireless Gateway to use the Serial Port correctly, the modem or ISDN TA must be set
as follows.
Setting
AT Command
AT&B1
Fixed baud rate setting
RTS/CTS flow control
DCD to track the presence of a carrier
DTR off to hang-up modem
DSR always on
AT&K3
AT&C1
AT&D2
AT&S0
If your Modem or ISDN TA uses the commands above, then the Initial String would be as
follows:
AT&F&B1&K3&C1&D2&S0X4
Notes:
•
•
•
The command "AT&F" is used to set the modem to the factory default settings, to ensure a
consistent starting point.
For some Mircocom and other modems, the "ATX4" command is not sufficient - a "W2"
command (no "AT") must be used as well.
ISDN TAs may not use these commands; please check your user guide for your ISDN TA.
Finding the current Initial String
If your modem or ISDN TA is already working correctly using the PC's serial port, but you
don’t know what the initialization string is, you can use the following procedure to find out.
1. Select My Computer, then Dial-Up Networking.
2. Select the icon for your connection, then Properties.
3. Click the Configure button, then the Connection tab, as shown below.

Figure 40: Advanced Connection (W95/98)
5. Check the option Record a log file. Then click OK and exit.
6. Use Dial-up Networking to make your on-line connection normally. A log file
MODEMLOG.TXT will be created in your Windows directory.
7. Use Notepad or another editor to read and print the file MODEMLOG.TXT.
8. Examine the file to determine the Initial String value. It will be near the beginning of the
file, and look something like the example shown previously.
