Overview
Thank you for purchasing the NetComm NB5 ADSL/ADSL2 Modem Router. NetComm
brings you the Next Generation of ADSL technology with ADSL-2*, which boosts ADSL’s
performance, improves interoperability, and supports new applications, services and deploy-
ment conditions.
NetComm’s implementation of ADSL-2* and ADSL-2+* ensures that the NB5 operates with
existing ADSL services while delivering optimal performance in all modes of operation. Pow-
ered by the latest ADSL-2* TI chipset, NetComm’s NB5 increases downstream data rates by
up to 50% (12Mbps) and 100% (25Mbps) for ADSL2 Plus* mode ensuring that you can surf
the net or download your files quicker than ever before.
Security is a key issue with Broadband users and NetComm’s NB5 does not leave you
exposed. Employing the latest Active Firewall technology, the NB5 checks every packet of
data that comes in ensuring your defences are rock-solid against hackers, unauthorised entries,
probes and even Denial of Service attacks. What’s more, the NB5 is equipped with a VPN
pass-through feature allowing you to use a standard VPN client for Point-to-Point communica-
tion even while your Firewall is active.
The NB5 delivers the connection versatility needed to cater for today’s ADSL users. You can
simply attach the NB5 to a single PC by using the USB port or Ethernet port.
The NB5’s Port Forwarding and UPnP functions have made it easier for today’s Internet users
to configure and setup the myriad of Network Port Rules needed by Internet applications such
as On-Line Gaming, Peer-To-Peer file sharing and Messenger services to operate. NB5 has a
number of pre-configured rules for several games, just click on the game you wish to play on-
line and the rest is done for you.
Added to this, the NB5 introduces a QoS (Quality of Service) feature that gives you control
over which types of outgoing data are given priority by the router. With QoS you can tailor
your router settings to ensure that you can keep gaming or browsing even though your up-
stream bandwidth may be saturated by applications such as Peer-To-Peer file sharing.
* Your ISP must support and provide you with an ADSL-2 or ADSL-2+ service for these features to be available. This
product will operate as a standard ADSL Modem Router when an ADSL-2 service is not available.
This reference manual assumes that the reader has an installed Ethernet card in the computer to be connected and
has basic to intermediate computer and Internet skills. However, basic Computer Networking, Internet, and Firewall
technology information is available from the NetComm Web site. See www.netcomm.com.au.

Do I need a Micro filter?
Micro filters are used to prevent common telephone equipment, such as phones, answering
machines and fax machines, from interfering with your ADSL service. If your ADSL enabled
phone line is being used with any other equipment other than your ADSL Modem then you
will need to use one Micro filter for each phone device.
Splitters may be installed when your ADSL line is installed or when your current phone line is
upgraded to ADSL. If your telephone line is already split you will not need to use a Microfil-
ter - check with your ADSL service provider if you are unsure.
Each micro filter is connected in-line with your telephone or fax machine so that all signals
pass through it. Telephones and/or facsimiles in other rooms that are using the same ex-
tension will also require Microfilters. The following diagram gives an example of connecting
your ADSL Modem/Router using a Microfilter.

Restoring Factory Defaults
This feature will reset the Modem to its factory default configuration. Occasions may present
themselves where you need to restore the factory defaults on your modem. Typical situations
are:
•You have lost your username and password and are unable to login to the modem.
•You have purchased the modem from someone else and need to reconfigure the device to
work with your ISP.
•You are asked to perform a factory reset by a member of the NetComm Support staff.
In order to restore your modem to its factory default settings, please follow these steps:
•Ensure that your Modem is powered on (for at least 10 seconds).
•Use a paper clip or a pencil tip to depress the reset button for ten seconds and release. At
this point, the reset is in progress. Do not power off the unit at this point.
•When indicator lights return to steady green, reset is complete. The default settings are
now restored. The entire process takes about 45 seconds to complete.
•Once you have reset the modem to its default settings you will be able to access the

Connecting your NB5
The NB5 can be connected via a USB cable or an Ethernet cable or both. The USB connection is
simply an ethernet simulation. As far as your computer is concerned the USB connection is an
Ethernet connection, hence DHCP and other protocols will work the same as for Ethernet.
To connect to your ADSL Router, you need to have either an Ethernet Port or a USB Port pres-
ent on your Computer/Notebook.
Connecting your NB5 ADSL Modem via ETHERNET
1. Connect your NB5 to either a computer directly or a network hub or switch using CAT5
ethernet cables.
2. Connect the power pack to the ADSL Modem and switch on the power switch.
3. Ensure that there is a LAN link light on the NB5.
4. Ensure that the computer you intend to use has an IP address in the same subnet as the
NB5 ADSL Modem. (e.g. the NB5’s default IP is 192.168.1.1 - your computer should be
on 192.168.1.100 or similar.) If you have DHCP enabled on your computer, the NB5 will
assign your computer a suitable IP address.
5. Ensure that your computer has a LAN link light.
6. Connect one end of the ADSL phone line to the NB5 ADSL Modem and the other end to
the wall socket.

YML763Rev2 NB5 Quick Start Guide
www.netcomm.com.au 13
Connecting your NB5 ADSL Modem via USB
1. Connect the power pack to the NB5 ADSL Modem and switch on the power switch.
2. Connect your NB5 to a computer directly via USB cable.
3. When the computer is booted, the Add New Hardware Wizard will launch and prompt you
to provide a driver for your NB5 ADSL Modem. Insert the CD provided.

detailed information. (You may need to restart your computer).
5. Connect one end of the ADSL phone line to the NB5 ADSL Modem and the other end to
the wall socket.
Installing the USB driver (Windows 98/Me/2000/XP only)
When you install the USB driver on your computer it creates a Virtual Ethernet Adapter,
which can be configured in the same way as a Network Interface card with DHCP or static IP
address. To install the USB driver please follow the steps below:
1. Boot your machine into Windows 98/Me/2000/XP.
2. Insert your NetComm NB5 CD into your CD-ROM drive.
3. Plug power up to your NB5 and switch ON.
4. Plug a USB cable from the back of the unit into a spare USB socket on your computer.
5. The Windows “Add New Hardware Wizard” should appear. Click Next to continue.
6. Ensure the option “Search for the best driver….” is chosen and click Next.
7. Choose “Specify location”, untick any other boxes and click on the Browse button. Open
the CD-ROM drive location of your NetComm NB5 CD and then select the ‘USBdriver’
folder. The USB driver will be installed.

Configuring your NB5
You will need to log directly into the configuration page of the modem and configure the basic
settings for your Internet connection. Your ISP should provide you with the necessary information to
complete this step.
The settings that you most likely need to change to access the Internet are grouped onto a single
EasyConfig page.
To configure your modem follow the steps below:
Note: Ensure that your PC is setup as a DHCP client. Refer to the Computer Hardware
Configuration section for instructions on how to set this up with different Operat-
ing Systems.
1. Insert the CD into your CD-ROM drive. An autorun screen will appear. Click on Config-
ure Modem.
(Alternatively, if the CD-ROM is not available, you can open a web browser and type
http://192.168.1.1 in the location bar to access the modem’s EasyConfig setup screen
directly.)
2. The login page will be displayed. Enter the modem’s username and password.
The default username is admin.
The default password is admin.
Click on Log In.
3. The EasyConfig page will be displayed.

YML763Rev2 NB5 Quick Start Guide
www.netcomm.com.au 15
4. Check with your ISP what Protocol your modem needs to use to connect to the Internet. If
unsure, leave the default selection of PPPoE.
5. In the User ID field, enter the Username that your ISP has provided. In the password field,
enter the password that your ISP has given you.
Note: If your ISP has provided you with Static addressing details you will need to ac-
cess the Advanced Settings of your modem to configure these. Please refer to
the section on Advanced Settings in the NB5 User Manual on the CD for instruc-
tions.
6. The default VPI / VCI settings for most connections is 8 / 35 in Australia. Do not change
these unless your ISP has instructed you to do so.
7. Click on the Apply button to save the settings you have entered. The modem will auto-
matically reboot. Refresh the web page after 20 seconds.
8. If the settings you entered were correct and you have an ADSL connection established the
Status light will change to green.
9. You should now be able to access the Internet with a web browser, email client or other
Internet application.
10. If the status light remains red after 45 seconds and you have refreshed your web page
several times, check the following:
• ADSL Link light on your modem is solid green; If not, you do not have a connection
established with your local DSLAM. Please call your ISP who will assist in resolving
this.
• If you have a solid green light on your modem for the ADSL Link, check that the user-
name / password you entered are correct and try again;
• If the above two suggestions don’t resolve the issue, please contact your ISP;
TIP: To test your Internet connection while the modem is attempting to apply the
settings, you can open a DOS prompt (Start > Run > cmd) and execute a con-
tinual ping command to a public server’s IP address on the Internet. Once you
receive a reply from the server you know that you are connected. This can take
up to 30 seconds. e.g: c:/ ping 210.0.111.111 -t

Appendix A: Troubleshooting
Below is a list of commonly asked questions. Before calling technical support, please look
through these issues to see if they help to solve your problem.
The ADSL Router is not functional
1. Check to see that the power LED is red and than the network cables are installed correctly.
2. Check to see that the ETH/LAN, ADSL and PPP LEDs are green.
3. Check to see that the ADSL LED is green
4. Check the settings on your PC.
5. From your PC, can you PING the ADSL Router? Assuming that the ADSL Router has
DHCP enabled and your PC is on the same subnet as the gateway, you should be able to
PING the gateway.
6. Can you PING the WAN IP? Your ISP should have provided the IP address of their server.
If you can ping the ADSL Router and your protocols are configured correctly, you should
be able to ping the ISPs network. If you cannot PING the ISPs network, make sure you
are using the correct protocols with the correct VPI/VCI values.
7. Make sure NAT is enabled for your connection. If NAT is disabled the ADSL Router will
not route frames correctly (except in Bridge connection).
I can’t connect to the ADSL Router.
1. Check to see that the power LED is red and that the network cables are installed correctly.
2. Make sure that your PC and the ADSL Router is on the same network segment. The
ADSL Router’s default IP address is 192.168.1.1. If you are running a Windows based
PC, you can open a DOS window and type IPCONFIG; make sure that the network adapt-
er that is connected to the gateway is within the same 192.168.1.x subnet. For Windows
98 SE computers you need to run ‘winipcfg’ (Start>Run>winipcfg).
3. Also, your PC’s Subnet Mask should match the gateways subnet mask. The gateway has a
default subnet mask of 255.255.255.0.
4. If this still does not work, press the reset button for 10 seconds. This will place the gate-
way into its factory default state. Go through the above procedures again.
5. Make sure NAT is enabled for your connection. If NAT is disabled the ADSL Router will
not route frames correctly (except in Bridge connection).
The DSL Link LED continues to blink but does not go solid
1. This means that the DSL line is trying to train but for some reason it cannot establish a
valid connection. The main cause of this is that you are too far away from the central of-
fice. Contact your DSL service provider for further assistance.
2. Verify that the phone line is connected directly to the wall and to the line input on the
ADSL Router.
3. Make sure that for every parallel phone line connected to telephone or fax to install with a
micro filter.

YML763Rev2 NB5 Quick Start Guide
www.netcomm.com.au 19
The ADSL Link LED is always off
1. Make sure you have ADSL service. You should get some kind of information from your
ISP that states that the ADSL service is installed. You can usually tell if the service is
installed by listening to the phone line; you will hear some high-pitched noise. If you do
not hear high-pitched noise, contact your ISP.
2. Verify that the phone line is connected directly to the wall and to the line input on the
ADSL Router. If the phone line is connected to the phone side of the ADSL Router or you
have a splitter installed on the phone line, the ADSL light will not come on.

Appendix B: ADSL Router terms
What is a firewall?
A firewall is protection between the Internet and your local network. It acts similarly to the
firewall in your car, protecting the interior of the car from the engine. Your car’s firewall has
very small opening that allow desired connections from the engine into the cabin (gas pedal
connection, etc), but if something happens to your engine, you are protected.
The firewall in the ADSL Router is very similar. Only the desired connections that you allow
are passed through the firewall. These connections are normally originating from the local
network; such as web browsing, checking your email, downloading a file, and playing a game.
However, in some cases, you can allow incoming connections so that you can run programs
like a web server.
What is NAT?
NAT stands for Network Address Translation. Another name for it is Connection Sharing.
What does this mean? Your ISP provides you with a single network address for you to access
the Internet through. However, you may have several machines on your local network that
want to access the Internet at the same time. The ADSL Router provides NAT functionality
that converts your local network addresses to the single network address provided by your ISP.
It keeps track of all these connections and makes sure that the correct information gets to the
correct local machine.
Occasionally, there are certain programs that don’t work well through NAT. Some games, and
some applications have a bit of trouble. The ADSL Router contains special functionality to
handle the vast majority of these troublesome programs and games. NAT does cause problems
when you want to run a SERVER though. When running a server, please see the DMZ section
below.
What is a DMZ?
DMZ really stands for Demilitarized Zone. It is a way of separating out part of your local
network so that is more open to the Internet. Suppose that you want to run a web-server, or a
game server. Normal servers like these are blocked from working by the NAT functionality.
The solution is to “isolate” the single local computer into a DMZ. This makes the single com-
puter look like it is directly on the Internet, and others can access this machine.
Your machine isn’t really directly connected to the Internet, and it really has an internal local
network address. When you provide the servers network address to others, you must provide
the address of the ADSL Router. The ADSL Router “fakes” the connection to your machine.
You should use the DMZ when you want to run a server that others will access from the
Internet. Internal programs and servers (like print servers, etc) should NOT be connected to
the DMZ
