Assigning static Internet information to your PCs
In some cases, you may want to assign Internet information to
some or all of your PCs directly (often called “statically”), rather than
allowing the ADSL2+ Router to assign it. This option may be
desirable—but not required—if:
„ You have obtained one or more public IP addresses that
you want to always associate with specific computers (for
example, if you are using a computer as a public web
server).
„ You maintain different subnets on your LAN (subnets are
described in Appendix A).
Before you begin, be sure to have the following information on hand.
Contact your ISP if necessary:
„ The IP address and subnet mask to be assigned to each
PC.
„ The IP address of the default gateway for your LAN. In
most cases, this is the address assigned to the LAN
interface on the ADSL2+ Router. By default, the LAN
interface is assigned this IP address: 192.168.1.1. (You
can change this number, or another number can be
assigned by your ISP. See Chapter 4 for more information.)
„ The IP address of your ISP’s Domain Name System (DNS)
server.
On each PC, follow the instructions on pages 16 through 20 relating
only to checking for and/or installing the IP protocol. Once it is
installed, continue to follow the instructions for displaying Internet
Protocol (TCP/IP) properties. Instead of enabling dynamic
assignment of the IP addresses for the computer, DNS server, and
default gateway, click the radio buttons that enable you to enter the
information manually.
Note
Your PCs must have IP addresses that place them in the same
subnet as the ADSL2+ Router’s LAN interface. If the IP addresses
you manually assign to your LAN PCs are in a different subnet than
the LAN interface, follow the instructions in Chapter 4 to change the
LAN interface IP address as needed.

Connecting a computer to the USB port
If you use the ADSL2+ Router’s USB port to connect to a PC, you
must install the provided USB driver software on the PC. The driver
enables Ethernet-over-USB communication with the ADSL2+
Router.
Configuring the USB computer is a two-part process:
„ In USB Driver Installation Part 1, you install the USB driver
on the PC.
„ In USB Driver Installation Part 2, you configure the IP
properties on the PC.
USB Driver Installation Part 1. Installing the USB Driver on the
PC:
1. Ensure that the USB cable is not connected to the USB
port on the PC. The installation program will prompt you
when to connect the cable.
2. Copy the USB installation files to a temporary directory on
the USB computer.

25
USB Driver Installation Part 2. Configuring IP properties on the
USB PC. Now that the USB driver installation is complete, you must
configure the USB PC so that its IP properties place it in the same
subnet as the ADSL2+ Router’s USB port. There are two ways to
do this:
„ The ADSL2+ Router is configured to assign an appropriate
IP address to the USB PC. If you want to use this
automatic assignment feature, called “DHCP server,” you
must configure the USB PC to accept dynamically
assigned IP information. Follow the instruction on pages 16
through 20 that correspond to the operating system
installed on your PC.
„ If you want to assign a static IP address to the PC, follow
the instructions on page 21 and use the following
information:
o
In the Network and Dial-up Connections window, be
sure to select the icon that corresponds to your new
USB connection (not the one that corresponds to your
Ethernet NIC). When you display properties for the
icon, the following text should display in the Connect
Using text box:
USB IAD LAN Modem #n
o
The USB interface on the ADSL2+ Router is
preconfigured with these properties:
USB interface IP address: 192.168.1.2
USB interface subnet mask: 255.255.255.0
Therefore, your PC must be configured as follows:
IP address: 192.168.1.n where n is a
number from 3 to 254.
Subnet mask: 255.255.255.0
Default gateway: 192.168.1.2

Default Router Settings
The ADSL2+ Router can provide a variety of services to your
network. The device is preconfigured with default settings for use
with a typical home or small office network.
Table 1 lists some of the most important default settings; these and
other features are described fully in subsequent chapters. If you are
familiar with network configuration, review the settings in Table 1 to
verify that they meet the needs of your network. Refer to the Quick
Configuration page instructions (on page 26) or to the document
sections referenced in the table for further instructions. If you are
unfamiliar with these settings, try using the device without
modification, or contact your ISP for assistance.
Before you attempt to modify any settings, review Chapter 3 for
general information about accessing and using the Configuration
Manager program. We strongly recommend that you contact your
ISP prior to changing the default configuration.

Table 1. Default Settings Summary
Option Default Properties Explanation/Instructions
LAN interfaces — connecting to your network
Ethernet
Static IP address: 192.168.1.1
Subnet mask: 255.255.255.0
DHCP server pool of addresses:
192.168.1.3 through 192.168.1.34
The LAN interface connects the device to your Ethernet
network. Typically, you will not need to change the IP
address. See Chapter 4 for instructions.
The DHCP service (see Chapter 8) is enabled for operation
over this interface, with a pool of private IP addresses for
dynamic assignment to your LAN computers. To use this
service, you must set up your computers to accept IP
information dynamically, as described in Quick Start Part 2.
USB
Static IP address: 192.168.1.2
Subnet mask: 255.255.255.0
The USB interface can connect to a single USB-enabled
computer with an IP address in the same subnet. See
Chapter 4 for instructions.
WAN interface — connecting to the Internet
ATM VC
VPI = 0
VCI = 35
The VPI and VCI values make up a VC (virtual circuit) that
determines the path your data must take to connect over the
phone lines to the ISP. These values must be changed as
directed by your ISP. See Chapter 5 for more information.
PPP interface
PPPoE interface
Login: guest
Password: guest
The PPP interface determines the method of communication
with your ISP and logging in to their servers. A particular type
of PPP interface – PPP over Ethernet (PPPoE) – is
configured by default, with the ISP login information shown.
See “Configuring PPP Interfaces” on page 53 for instructions
on modifying this information as required by your ISP.
Services
NAT (Network
Address
Translation)
NAPT rule enabled Your computers’ private IP addresses (see DHCP above) will
be translated to your public IP address whenever they
access the Internet. See Chapter 4 for a description of the
NAT service.

Testing Your Setup
The Quick Start process should enable any computer on your LAN
to use the ADSL2+ Router to access the Internet.
To test the connection, turn on the device, wait about 30 seconds,
and then verify that its LEDs are illuminated as shown in Table 2.
Table 2. LED Indicators
LED Behavior
PWR
Displays solid green to indicate that the device is turned
on.
LAN
Displays solid green when the Ethernet connection is up.
Flashes while data is being sent to and received from your
LAN PCs.
DSL Displays solid yellow when the DSL line is up. Flashes
during DSL handshake.
If the LEDs illuminate as expected, test your Internet connection
from a LAN computer (and from the USB computer, if applicable):
Open your web browser and type the URL of any external website
(such as http://www.yahoo.com). The LED labeled Internet should
be blinking rapidly and may appear solid as the device connects to
the site.
If the LEDs do not illuminate as expected or the web page does not
display, see Appendix A for troubleshooting suggestions. Or,
contact your ISP for assistance.
