Introduction
This Chapter provides an overview of the ADSL VoIP Router's features and
capabilities.
Congratulations on the purchase of your new ADSL VoIP Router. The ADSL VoIP Router is a
multi-function device providing the following services:
• ADSL Modem.
• Shared Broadband Internet Access for all LAN users.
• Wireless Access Point for 802.11b and 802.11g Wireless Stations.
• 1 Ethernet port for 10BaseT or 100BaseT connections.
• 1 FXS for telephone
• 1 FXO for PSTN
• Optional USB port for USB connection
Figure 1: ADSL VoIP Router
ADSL VoIP Router Features
The ADSL VoIP 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 ADSL VoIP Router, 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).

• Built-in ADSL Modem. The ADSL VoIP Router has a built-in ADSL modem, support-
ing all common ADSL connections.
• IPoA, PPPoE, PPPoA, Direct Connection Support. The ADSL VoIP Router sup-
ports all common connection methods.
• Auto-detection of Internet Connection Method. In most situations, the ADSL VoIP
Router can test your ADSL and Internet connection to determine the connection method
used by your ISP.
• Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the ADSL
VoIP Router supports both Dynamic IP Address (IP Address is allocated on connection)
and Fixed IP Address.
Advanced Internet Functions
• Application Level Gateways (ALGs). Applications which use non-standard connec-
tions or port numbers are normally blocked by the Firewall. The ability to define and allow
such applications is provided, to enable such applications to be used normally.
• Special Applications. This feature, also called Port Triggering, allows you to use
Internet applications which normally do not function when used behind a firewall.
• Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
• Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows
users to connect to Servers on your LAN using a Domain Name, even if you have a dy-
namic IP address which changes every time you connect.
• URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
• Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall
Rules to determine which incoming and outgoing traffic should be permitted.
• Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at
certain times. This provides great flexibility in controlling Internet -bound traffic.
• Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog
Server. Log data can also be E-mailed to you.
• 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 ADSL VoIP 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. WEP encrypts any data before transmission, providing pro-
tection against snoopers.
• WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission,
providing protection against snoopers. The WPA-PSK is a later standard than WEP, and
provides both easier configuration and greater security than WEP.
Introduction
3
• Wireless MAC Access Control. The Wireless Access Control feature can check the
MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless
Stations can access your LAN.
• Simple Configuration. If the default settings are unsuitable, they can be changed
quickly and easily.
LAN Features
• 1 Ethernet port. The ADSL VoIP Router incorporates a 1-port 10/100BaseT, making it
easy to create or extend your LAN.
• 1 Optional USB port.
• DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The ADSL VoIP Router can act as a DHCP
Server for devices on your local LAN and WLAN.
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configura-
tion.
• Configuration File Upload/Download. Save (download) the configuration data from
the ADSL VoIP Router to your PC, and restore (upload) a previously-saved configuration
file to the ADSL VoIP Router.
• Remote Management. The ADSL VoIP Router can be managed from any PC on your
LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally) be
configured via the Internet.
• Network Diagnostics. You can use the ADSL VoIP Router to perform a Ping or DNS
lookup.
Security Features
• Password - protected Configuration. Password protection is provided to prevent
unauthorized users from modifying the configuration data and settings.
• Wireless LAN Security. WPA-PSK, WEP and Wireless access control by MAC ad-
dress are all supported. The MAC-level access control feature can be used to prevent
unknown wireless stations from accessing your LAN.
• NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology 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 ADSL VoIP Router.
• 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 band-
width and so many resources that Internet access becomes unavailable. The ADSL VoIP
Router incorporates protection against DoS attacks.

figure 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
• Netscape 7
• Internet Explorer V5.01 or later
Preparation
Before attempting to configure the ADSL VoIP Router, please ensure that:
• Your PC can establish a physical connection to the ADSL VoIP Router. The PC and the
ADSL VoIP Router must be directly connected (using the Hub ports on the ADSL VoIP
Router) or on the same LAN segment.
• The ADSL VoIP Router must be installed and powered ON.
• If the ADSL VoIP Router's default IP Address (192.168.0.1) is already used by another
device, the other device must be turned OFF until the ADSL VoIP Router is allocated a new
IP Address during configuration.
Using your Web Browser
To establish a connection from your PC to the ADSL VoIP Router:
1. After installing the ADSL VoIP Router in your LAN, start your PC. If your PC is already
running, restart it.

If you can't connect
If the ADSL VoIP Router does not respond, check the following:
• The ADSL VoIP 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 ADSL VoIP 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 ADSL VoIP Router's de-
fault 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 ADSL VoIP 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 ADSL VoIP 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") net-
works. For other networks, use the Subnet Mask for the LAN segment
to which the ADSL VoIP Router is attached (the same value as the PCs
on that LAN segment).
DHCP Server • If Enabled, the ADSL VoIP 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 ADSL VoIP Router as the default Gateway. See the follow-
ing 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.
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.
ADSL VoIP Router User Guide
16
• The ADSL VoIP 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 ADSL VoIP 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 ADSL VoIP 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 ADSL VoIP Router's, the following procedure is required.
• Disable the DHCP Server feature in the ADSL VoIP Router. This setting is on the LAN
screen.
• Configure the DHCP Server to provide the ADSL VoIP Router's IP Address as the Default
Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP for all non-Server versions of Windows.
See Chapter 4 - Client Configuration for the procedure to check these settings.

than WEP, and should be used if possible. WPA-PSK is the version
of WPA, which does NOT require a Radius Server on your LAN.
PSK Enter the PSK (network key). Data is encrypted using a key derived
from the network key. Other Wireless Stations must use the same
network key. The PSK must be from 8 to 63 characters in length.
WPA Encryption The WPA-PSK standard allows different encryption methods to be
used. Select the desired option. Wireless Stations must use the same
encryption method.

Router Both the ADSL Modem and the Router features are operational. In this mode,
this device can provide shared Internet Access to all your LAN users. Also,
by default, it acts a DHCP Server, providing an IP address and related infor-
mation to all Wireless and LAN users.
Modem Only the ADSL Modem component is operational.
• All Router features are disabled. This device is "transparent" - it does
not perform any operations or make any changes to the network traffic
passing through it.
• You need to have a DHCP Server on your LAN to provide IP addresses
to the Wireless clients using this Access Point.
• All traffic received on either the Wireless or LAN interface will be sent
over the ADSL connection.
Notes:
• Generally, you should NOT use modem mode. Only select this mode if you are sure this is
what you want.
• After changing the mode, this device will restart, which will take a few seconds. The menu
will also change, depending on the mode you are in.
• The Wireless Access Point can function in either Router or Modem mode. But generally it
is not a good idea to combine a Modem with an Access Point, because all data received
from the wireless stations will be sent over the modem connection. (Since the modem is
transparent, it does not examine the traffic to determine whether the traffic is for the LAN or
the WAN.)
• For details on using Modem Mode, see Chapter 8.

Chapter 4
PC Configuration
This Chapter details the PC Configuration required on the local ("Internal")
LAN.
Overview
For each PC, the following may need to be configured:
• TCP/IP network settings
• Internet Access configuration
• Wireless configuration
Windows Clients
This section describes how to configure Windows clients for Internet access via the ADSL
Vo IP Router.
The first step is to check the PC's TCP/IP settings.
The ADSL VoIP 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 ADSL VoIP Router settings, and the default Windows
TCP/IP settings, no changes need to be made.
• By default, the ADSL VoIP 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 re-
quired:
• The Gateway must be set to the IP address of the ADSL VoIP Router
• The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re-
configure the Router itself. Refer to Chapter 8 - Advanced
Setup for details.

The "DMZ PC" is effectively outside the Firewall, mak-
ing it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.
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".
The Special Applications screen can be reached by clicking the Special Applications button

Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows Inter-
net 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 DynDNS 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 ADSL VoIP Router's DDNS screen.
4. The ADSL VoIP 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.

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 56: 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.
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.
Virtual Servers Screen
• The "Virtual Servers" feature allows Internet Users to access PCs on your LAN.
• The PCs must be running the appropriate Server Software.
• For Internet Users, ALL of your Servers have the same IP address. This IP address is
allocated by your ISP.
• To make it easier for Internet users to connect to your Servers, you can use the "DDNS"
feature. This allows Internet users to connect to your Servers with a URL, rather than an IP
address. This technology works even if your ISP allocates dynamic IP addresses (IP ad-
dress is allocated upon connection, so it may change each time you connect).

For each entry, the PC must be running the appropri-

If the desired Server type is not listed, you can define
your own Servers, using the Firewall Rules.
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 to allow users to connect to your Virtual
Servers using a URL, rather than an IP Address.
From the Internet, ALL Virtual Servers have
the IP Address allocated by your ISP

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.
However, if you do use a fixed IP address on some devices on your LAN, you should enter
details of each such device into the PC database, using the PC Database screen.
PC Database Screen
An example PC Database screen is shown below.
Figure 58: PC Database
• 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 ADSL VoIP 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.

ber is recommended. The default value is 8080.
The port number must be specified in your Browser when you con-
nect, as detailed above.

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 ADSL
VoIP 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.
3. You will then be prompted for the login name and password for this device.

Routing
Overview
• If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
• If the ADSL VoIP 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 ADSL VoIP 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 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 Data center Server as a software Router, enable RIP on the ADSL
VoIP 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 ADSL VoIP
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 ADSL VoIP Router as the Default Route or Default
Gateway.
Advanced Features
85
Local Router
The local router is the Router installed on the same LAN segment as the ADSL VoIP Router.
This router requires that the Default Route is the ADSL VoIP 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 ADSL VoIP Router.
Metric 1
Other Routers on the Local LAN
Other routers on the local LAN must use the ADSL VoIP Router's Local Router as the Default
Route. The entries will be the same as the ADSL VoIP Router's local router, with the exception
of the Gateway IP Address.
• For a router with a direct connection to the ADSL VoIP Router's local Router, the Gateway
IP Address is the address of the ADSL VoIP Router's local router.
• For routers which must forward packets to another router before reaching the ADSL VoIP
Router's local router, the Gateway IP Address is the address of the intermediate router.

Chapter 8
Modem Mode
This Chapter explains configuration and operation when in "Modem" or
"Bridge" mode..
Overview
There are two modes available on the Mode screen.
• Router - Both the ADSL Modem and the Router features are operational. In this mode, this
device can provide shared Internet Access to all your LAN users. Also, by default, it acts a
DHCP Server, providing an IP address and related information to all Wireless and LAN us-
ers.
• Modem - Only the ADSL Modem component is operational. All Router features are dis-
abled. This device is "transparent" - it does not perform any operations or make any
changes to the network traffic passing through it. You need to have a DHCP Server on
your LAN to provide IP addresses to the Wireless clients using this Access Point.
This Chapter describes operation while in Modem mode.
Management Connections
When this device restarts in Modem mode, the IP address does not change, but the DHCP
server is disabled. However, your PC will usually retain the IP address provided by the DHCP
Server, so the connection will be automatically re-established. You then need to ensure that the
IP address of this modem is suitable for your LAN.
• You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless
clients using this Access Point.
• This Modem/AP must be a valid device on your LAN, to allow management connections.
You must assign a (fixed) IP address which is within the address range used on your LAN,
but not within the address range used by your DHCP server.
When you connect in future, just connect normally, using the IP address you assigned.
1. Start your WEB browser.
2. In the Address box, enter "HTTP://" and the current IP Address of the ADSL VoIP Modem,
as in this example, which uses the ADSL VoIP Modem's default IP Address:
HTTP://192.168.0.1
3. When prompted for the User name and Password, enter admin for the user name, and the
current password, as set on the password screen. (The password is the same regardless of
the mode.)

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 ADSL
VoIP Router and some possible solutions to them. If you follow the suggested steps and the
ADSL Vo IP Router still does not function properly, contact your dealer for further advice.
General Problems
Problem 1: Can't connect to the ADSL VoIP Router to configure it.
Solution 1: Check the following:
• The ADSL VoIP Router is properly installed, LAN connections are OK,
and it is powered ON.
• Ensure that your PC and the ADSL VoIP 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 compati-
ble with the ADSL VoIP 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
ADSL VoIP Router.
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.
Solution 1: A number of things could be causing this. Try the following troubleshooting
steps.
• 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
ADSL VoIP 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.)
• Check the ADSL VoIP Router's status screen to see if it is working
correctly.
Problem 2: Some applications do not run properly when using the ADSL VoIP Router.
A
ADSL VoIP Router User Guide
94
Solution 2: The ADSL VoIP Router processes the data passing through it, so it is not
transparent.
For incoming connections, you must use the Virtual Server or Firewall Rules
to specify the PC which will receive the incoming traffic.
You can also 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 ADSL VoIP Router must have the same setting for
WEP. The default setting for the ADSL VoIP Router is disabled, so your
wireless station should also have WEP disabled.
• If WEP is enabled on the ADSL VoIP Router, your PC must have WEP
enabled, and the key must match.
• If the ADSL VoIP Router's Wireless screen is set to Allow Trusted PCs
only, then each of your Wireless stations must have been designated as
"Trusted", or the Wireless station will be blocked.
• To see if radio interference is causing a problem, see if connection is
possible when close to the ADSL VoIP 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 connec-
tion speed, you can experiment with the following:
• ADSL VoIP Router location.
Try adjusting the location and orientation of the ADSL VoIP 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 ADSL VoIP Router.
95
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 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 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.)
B
ADSL VoIP Router User Guide
96
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.
• 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 exis ting "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.
WPA-PSK
WPA-PSK is another standard for encrypting data before it is transmitted. This is a later stan-
dard than WEP (Wired Equivalent Privacy), and provides greater security for your data. Data is
encrypted using a 256Bit key which is automatically generated and changed often.
If all your Wireless stations support WPA-PSK, you should use this instead of WEP.
If WPA-PSK is used, the Wireless Stations and the Access Point must have the same settings
for each of the following:
WPA PSK
(Pre-shared Key) Enter the same value on every station and the AP. The PSK
must be from 8 to 63 characters in length. The 256Bit key
used for the actual encryption is derived from this key.
Encryption The same encryption method must be used. The most
common encryption method is TKIP. Another widely-
supported method is AES.
Appendix A - Troubleshooting
97
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.
Wireless
Security The Wireless Stations and the Access Point must use the same settings
for Wireless security. (None, WEP, WPA-PSK).
WEP: If WEP is used, the Key size (64Bit, 128Bit), Key value, and
Authentication settings must be the same on the Wireless Stations and
the Access Point.
WPA-PSK: If WPA-PSK is used, all Wireless Stations must be set to
use WPA-PSK, and have the same Pre-shared Key and encryption
system.
For Ad-hoc networks (no Access Point), all Wireless stations must use
the same security settings.

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.
