Items You Need
If you are installing the Data Gateway yourself, make sure you have the follow ing
items on hand before continuing:
•Data Gateway package: see What’s in the Box? for a list of items in the
package.
•Coaxial cable (coax): as shown in the image to the left, this is a round
cable with a connector on each end. It is the same kind of wire used to con-
nect to your television for cable TV. You can buy coax from any electronics
retailer and many discount stores; make sure it has connectors on both
ends. There are two types of connectors, slip-on and screw-on; the screw-
on connectors are best for use with your Data Gateway. The coax should be
long enough to reach from your Data Gateway to the nearest cable outlet.
Note: For best performance, use high-quality RG-6 type coax cable and min-
imize or eliminate splitters between the cable jack and the Data Gateway.
•Splitter (optional): provides an extra cable connection by splitting a sin-
gle outlet into two. You may need a splitter if you have a TV already con-
nected to the cable outlet that you want to use. You can buy a splitter from
any electronics retailer and most discount stores; you may also need a short
piece of coax cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Data Gateway and TV to the splitter.
Note: A splitter effectively cuts the signal in half and sends each half to its
two outputs. Using several splitters in a line may deteriorate the quality of
your television and/or internet connection.
•Wall-mounting bracket (optional): if you want to wall-mount your Data
Gateway, you need to obtain two drywall anchors or wood screws and order
a wall-mounting bracket from your cable company.
•Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this in-
formation carefully and contact your cable company if you have any ques-
tions.

Getting Service
Before trying to use your new Data Gateway, contact your local cable company to
establish an Internet account. When you call, have the fol lowing information ready:
• the Data Gateway serial number and cable MAC addresses of the unit
(printed on a sticker on the bottom of the Data Gateway)
• the model number of the Data Gateway
If the Data Gateway was provided by your cable company, they already have the
required information.
In addition, you should ask your cable company the following questions:
• Do you have any special system requirements or files that I need to down-
load after I am connected?
• When can I start using my Data Gateway?
• Do I need a user ID or password to access the Internet or my e-mail?

About this Manual
This manual covers the Touchstone DG1670 Data Gateway. The model number is
on the label affixed to the Data Gateway. See the image at the left.
What About Security?
Having a high-speed, always-on connection to the Internet requires a certain
amount of responsibility to other Internet users—including the need to maintain a
reasonably secure system. While no system is 100% secure, you can use the fol-
lowing tips to enhance your system’s security:
• Keep your operating system updated with the latest security patches. Run
the system update utility at least weekly.
• Keep your email program updated with the latest security patches. In addi-
tion, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
• Install a virus checker and keep it updated.
• Avoid providing web or file-sharing services over your Data Gateway. Be-
sides certain vulnerability problems, most cable companies prohibit run ning
servers on consumer-level accounts and may suspend your account for vi-
olating your terms of service.
• Use the cable company’s mail servers for sending email.
• Avoid using proxy software unless you are certain that it is not open for
abuse by other Internet users (some are shipped open by default). Crimi-
nals can take advantage of open proxies to hide their identity when break-
ing into other computers or sending spam. If you have an open proxy, your
ca ble company may suspend your account to protect the rest of the net-
work.
• The DG1670 ships with wireless LAN security set by default (for the same
reasons that you should run only secured proxies). See the security label on
your product (shown on image at the left) for the factory security settings.
If you need to modify the default wireless security settings, see Configuring
Your Wireless Connection.

Ethernet or Wireless?
There are two ways to connect your computer (or other equipment) to the Data
Gateway. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more computers into a Local
Area Network (LAN). You can use the Ethernet connection if your computer has
built-in Ethernet hardware.
Note: To connect more than four computers to the DG1670 through the Ether -
net ports, you need an Ethernet hub (available at computer retail ers).
The Data Gateway package comes with one 4-foot (1.2m) Ethernet cable (the con-
nectors look like wide telephone connectors); you can purchase more cables if nec-
essary at a computer retailer. If you are connecting the Data Gateway di rectly to a
computer, or to an Ethernet hub with a cross-over switch, ask for Category 5e
(CAT5e) straight-through cable. CAT5e cable is required for gigabit Ethernet (Gig-
E), not regular CAT5 cable.
Wireless
Wireless access lets you connect additional (wireless-capable) devices to Data Gate-
way. The 802.11 wireless LAN standard allows one or more computers to access the
DG1670 using a wireless (radio) signal. These connections are in addition to the
connections supported via Ethernet.
Note: You can use the wireless connection if your computer has a built-in or af-
termarket wireless card. To learn more about which wireless hardware
works best with your com puter, see your computer dealer.
Both
If you have two or more computers, you can use Ethernet for up to four devices and
wireless for the others. To connect five or more computers to the Ethernet ports,
you will need an Ethernet hub (available at computer retailers.)

Installing and Connecting Your Data
Gateway
Before you start, make sure that:
• You have contacted your cable company and verified that they provide data
service using standard DOCSIS technology.
• You have all the items you need.
• Cable and power outlets are available near the computer. If a cable outlet is
not conveniently located, your cable company can install a new one.
If you have ordered service, your cable company should configure the Data Gate-
way automatically. You need only follow the instructions in this section to install
and connect the Data Gateway.

Selecting an Installation Location
There are a number of factors to consider when choosing a location to install your
Data Gateway:
• Is an AC outlet available nearby? For best results, the outlet should not be
switched and should be close enough to the Data Gateway that exten sion
cords are not required.
• Is a cable jack available? For best performance, keep the number of split-
ters between the jack and cable drop to a minimum. Each splitter attenuates
(re duces) the signal available to the Data Gateway. A large number of split-
ters can slow down the Internet connection.
• If you are connecting devices to the Ethernet ports, can you easily run ca-
bles between the Data Gateway’s location and those devices?
• If you want to mount the Data Gateway on a wall, does the location pro vide
a solid surface for secure attachment? For best results when mounting the
Data Gateway on drywall, position the Data Gateway so at least one of the
screws are fastened to a stud. This may prevent the Data Gateway from
pulling out of the wall in the future.
• If you want to install the Data Gateway on a desktop, is there enough space
on either side to keep the vents clear? Blocking the vents may cause over-
heating.
• How close are your wireless devices? The Data Gateway wireless con nection
range is typically 100–200 feet (30m–65m). A number of factors can affect
connection range, as described below.

Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless connections.
Note: Note that decreasing the range of your wireless network may be bene-
ficial, as long as the decreased range is sufficient for your needs. By lim-
iting your network’s range, you reduce interference with other networks
and make it harder for unwant ed users to find and connect to your net-
work.
Note: Setting the trasmit power level to High increases the range. Setting it
to Medium or Low decreases the range proportionately.
Increases range: • Raising the unit above the devices (for example, in-
stalling the Data Gateway in the upper floor of a multi-
story dwelling)
Decreases range: • Lowering the unit below the devices (for example, in-
stalling the Data Gateway in a basement)
• Metal or concrete walls between the Data Gateway and
other devices
• Large metal appliances, aquariums, or metal cabinets
between the Data Gateway and other devices
• Interference and RF noise (2.4 GHz wireless phones,
microwave ovens, or other wireless networks)
