This Quick Start provides basic instructions for connecting the WTM4151 to a
computer or LAN and to the Internet.
1. Part 1 describes setting up the hardware.
2. Part 2 describes how to configure Internet properties on your computer(s) and
how to install the software for using a computer attached to the USB port
3. Part 3 describes the default settings on the WTM4151, and refers you to the
appropriate chapter for instructions on modifying the defaults.
This Quick Start assumes that you have already established ADSL service with your
Internet service provider (ISP). These instructions provide a basic configuration that
should be compatible with your home or small office network setup. Refer to the
subsequent chapters for additional configuration instructions.
Part 1- Connecting the Hardware
In Part 1, you connect the device to the phone jack, the power outlet, and your
computer or network.
WARNING
Before you begin, turn the power off for all devices. These include
your computer(s), your LAN hub/switch (if applicable), and the
WTM4151.
Figure 1 illustrates the hardware connections. The layout of the ports on your device
may vary from the layout shown. Refer to the steps that follow for specific instructions.

Step 1. Connect the ADSL cable and optional telephone.
Connect one end of the provided phone cable to the port labeled ADSL on the rear
panel of the device. Connect the other end to your wall phone jack.
You can attach a telephone line to the device. This is helpful when the ADSL line uses
the only convenient wall phone jack. If desired, connect the telephone cable to the
port labeled PHONE.
WARNING
Although you use the same type of cable, The ADSL and PHONE
ports are not interchangeable. Do not route the ADSL connection
through the PHONE port.
Step 2. Connect the Ethernet cable.
If you are using the WTM4151 with a single computer, attach one end of a “straight”
Ethernet cable to the port labeled LAN and the other to your computer’s Ethernet port.
If you are connecting a LAN to the device, use a crossover cable to connect it to the
uplink port on the hub.
See Appendix B “Troubleshooting,” for a description of these cable types.
Step 3. Attach the power connector.
Connect the AC power adapter to the PWR connector on the back of the device and
plug in the adapter to a wall outlet or power strip.
Step 4. Turn on the WTM4151 and power up your systems.
Press the Power switch on the back panel of the device to the ON position.
Turn on and boot up your computer(s) and any LAN devices such as hubs or switches.
Step 5: Install USB software and connect the USB cable.
You can attach a single computer to the device using a USB cable. The USB port is
useful if you have an USB-enabled PC that does not have a network interface card for
attaching to your Ethernet network.
Before attaching the USB cable, you must install a USB driver and configure the
computer. For complete instructions, see page 12.

Part 2- Configuring your Computers
Part 2 of the Quick Start provides instructions for configuring the Internet settings on
your computers to work with the WTM4151.
Before you begin
By default, the WTM4151 automatically assigns all required Internet settings to your
PCs. You need only to configure the PCs to accept the information when it is assigned.
These instructions assume that your PCs are already connected to a LAN through
their network interface cards (NICs) and the appropriate Ethernet adapter software.
If you are attaching a PC via the USB port, see the USB configuration instructions on
page 12.
Follow the instructions that correspond to the operating system installed on each PC.

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 WTM4151 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, contact your ISP if you do not already have the following
information:
▶The IP address and subnet mask to be assigned to each PC to which you will be
assigning static IP information.
▶The IP address of the default gateway for your LAN. In most cases, this is the
address assigned to the LAN port on your WTM4151. By default, the LAN port is
assigned this IP address: 192.168.1.1. (You can change this number, or your ISP
can assign another number. See Chapter 5 for more information.)
▶The IP address of your ISP’s Domain Name System (DNS) server.
On each PC to which you want to assign static information, follow the instructions on
pages 8 through 11 relating only to checking for and/or installing the IP protocol. Once
it is installed, continue to follow the instructions for displaying each of the Internet
Protocol (TCP/IP) properties. Instead of enabling dynamic assignment of the IP
addresses for the computer, DNS server, and default gateway, clicks the radio buttons
that enable you to enter the information manually.

Configuring a computer connected to the USB port (If applicable)
If your WTM4151 includes a USB port for connecting to a PC, you must install the
provided USB driver software on the PC. The driver enables Ethernet-over-USB
communication with the WTM4151.
Configuring the USB computer is a two-part process:
▶In Part 1, you install the USB driver on the PC.
▶In Part 2, you configure the IP properties on the USB PC.
Part 3. Installing the USB Driver:
Ensure that the USB cable is not connected to the USB port on the PC or to the
USB port on the device.
The installation program will prompt you when to connect the cable.
1. Copy the USB installation file to a temporary directory on the USB computer.
2. In the folder where you copied the files, double-click on setup.exe to launch the
installation program.
The Welcome dialog box displays, as shown in Figure 2.

Note
Your PCs must have IP addresses that place them in the same subnet as
the WTM4151’s LAN port. If you manually assign IP information to all your
LAN PCs, you can follow the instructions in Chapter 5 to change the LAN
port IP address accordingly.
