Overview
Thank you for purchasing the NetComm NB1 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 deployment conditions.
NetComm’s implementation of ADSL-2* and ADSL-2+* ensures that the NB1 operates with existing ADSL services while delivering optimal performance in all modes
of operation. Powered by the latest ADSL-2* TI chipset, NetComm’s NB1 increases
downstream data rates by up to 50% (12Mbps) and 100% (25Mbps) for ADSL2
Plus* mode ensuring that you can surf the net or down load your files quicker than
ever before.
Security is a key issue with Broadband users and NetComm’s NB1 does not leave
you exposed. Employing the latest Active Firewall technology, the NB1 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
NB1 is equipped with a VPN pass-through feature allowing you to use a standard
VPN client for Point-to-Point communication even while your Firewall is active.
The NB1 delivers the connection versatility needed to cater for today’s ADSL users.
You can simply attach the NB1 to a single PC via the Ethernet port. Alternatively,
should you wish to share your Internet connection, the NB1 is equipped with an
in-built Router which will support multiple PCs with the addition of device such as a
NetComm 5- or 8-port Network Switch.
The NB1’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. NB1 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 NB1 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 upstream 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.
Note that due to the fact that the NB1 is an adaption of the NB5 multi-port router, several functions belonging to
the NB5 including LAN Groups are still represented by screens in the NB1 firmware. These screens to not have a
corresponding function in this model which will be noted in the manual where applicable.

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 Microfilter - 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 mo-
dem.
• 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 set-
tings 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 device's configuration web interface using http://192.168.1.1 with username
'admin' and password 'admin'.

Connecting your NB1
The NB1 is connected via an Ethernet cable.
To connect to your NB1, you will need to have an available Ethernet Port present on your
Computer/Notebook or on your network hub or switch.
1. Connect your NB1 to either a computer directly or a network hub or switch using
a CAT5 ethernet cable.
2. Connect the power pack to the ADSL Modem and switch on the power switch.
3. Ensure that there is a ETHERNET link light on the NB1.
4. Ensure that the computer you intend to use has an IP address in the same subnet as the NB1 ADSL Modem. (e.g. the NB1’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 NB1 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 NB1 ADSL port and the other
end to the ADSL-enabled line wall socket.

Configuring your NB1
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:

Appendix B: Cable Connections
This cable information is provided for your reference only. Please ensure you only
connect the appropriate cable into the correct socket on either this product or your
computer.
If you are unsure about which cable to use or which socket to connect it to, please
refer to the hardware installation section in this manual. If you are still not sure
about cable connections, please contact a professional computer technician or NetComm for further advice.
RJ-45 Network Ports
RJ-45 Network Ports can connect any networking devices that use a standard LAN
interface, such as a Hub/Switch Hub or Router. Use unshielded twisted-pair (UTP)
or shield twisted-pair (STP) cable to connect the networking device to the RJ-45
Ethernet port. Depending on the type of connection, 10Mbps or 100Mbps, use the
following Ethernet cable, as prescribed.
10Mbps: Use EIA/TIA-568-100-Category 3, 4 or 5 cable.
100Mbps: Use EIA/TIA-568-100-Category 5 cable.
Note: To prevent loss of signal, make sure that the length of any twisted-pair
connection does not exceed 100 metres.

Straight and crossover cable configuration
There are two types of the wiring: Straight-Through Cables and Crossover Cables.
Category 5 UTP/STP cable has eight wires inside the sheath. The wires form four
pairs. Straight-Through Cables has same pinouts at both ends while Crossover Cables has a different pin arrangement at each end.
In a straight-through cable, wires 1,2,3,4,5,6,7 and 8 at one end of the cable are
still wires 1~8 at the other end. In a crossover cable, the wires of 1,2,3,6 are reversed so that wire 1 become 3 at the other end of the cable, 2 becomes 6, and so
forth.
To determine which wire is wire 1, hold the RJ-45 cable tip with the spring clip
facing towards the ground and the end pointing away from you. The copper wires

An IP address consists of a network ID that identifies
the particular network the host belongs to, and a host
ID uniquely identifying the host itself on that network. A
network mask is used to define the network ID and the

they usually have an associated domain name that can be
