Coaxial cable (coax): This is a round cable with a connector on each end. It is the same
kind of wire used to connect 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 minimize or
eliminate splitters between the cable jack and the Data Gateway.
Splitter (optional): provides an extra cable connection by splitting a single outlet into
two. You may need a splitter if you have a TV already connected 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, telephone,
and/or internet connection.
Information packet: your cable company should furnish you with a packet containing
information about your service and how to set it up. Read this information carefully and
contact your cable company if you have any questions.
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 following information ready:
the Data Gateway serial number and cable MAC addresses of the unit (printed on the
Data Gateway)
the model number of the Data Gateway (printed on the Data Gateway)
If the Data Gateway was provided by your cable company, they already have the required
information.

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 following tips to enhance your
system’s security:
Keep the operating system of your computer 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 addition, 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. Besides certain
vulnerability problems, most cable companies prohibit running servers on consumer-
level accounts and may suspend your account for violating your terms of service.
Use the service provider’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). Criminals can take advantage of open
proxies to hide their identity when breaking into other computers or sending spam. If
you have an open proxy, your service provider may suspend your account to protect the
rest of the network.
The DG3450 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 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 DG3450 through the Ethernet ports, you
need an Ethernet hub (available at computer retailers).

The Data Gateway package comes with one 4-foot (1.2m) Ethernet cable (the connectors
look like wide telephone connectors); you can purchase more cables if necessary at a
computer retailer. If you are connecting the Data Gateway directly 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 Gateway. The
802.11 wireless LAN standard allows one or more computers to access the DG3450 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 aftermarket
plug-in wireless adapter. To learn more about which wireless hardware works best with your
computer, 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.)

should be close enough to the Data Gateway that extension cords are not required.

DRAFT
Chapter 4: Installing and Connecting your Data Gateway
Release 34 DRAFT 1.6 June 2017 Touchstone DG3450 Data Gateway User Guide
© 2017 ARRIS Enterprises LLC. All Rights Reserved. 19
Is a cable jack available? For best performance, keep the number of splitters between
the jack and cable drop to a minimum. Each splitter attenuates (reduces) the signal
available to the Data Gateway. A large number of splitters can slow down the Internet
connection.
If you are connecting devices to the Ethernet ports, can you easily run cables between
the Data Gateway’s location and those devices?
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 overheating.
How close are your wireless devices? The Data Gateway wireless connection range is
typically 100–200 feet (30m–65m). A number of factors can affect connection range, as
described below.
Desktop Mounting Instructions
Position the Data Gateway so that:
it stands vertically on its base (Do not lay it flat on its side.)
air flows freely around it
the back faces the nearest wall
it will not fall to the floor if bumped or moved
the ventilation holes on the sides of the unit are not blocked
Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless connections.
Increases range Raising the unit above the devices (for example, installing the Data
Gateway in the upper floor of a multi-story dwelling)
Adding a wireless extender to the network
Decreases range Lowering the unit below the devices (for example, installing 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)
Note: Note that decreasing the range of your wireless network may be beneficial, as long as
the decreased range is sufficient for your needs. By limiting your network’s range, you
reduce interference with other networks and make it harder for unwanted users to find and
connect to your network.
Note: Setting the transmit power level to High increases the range. Setting it to Medium or
Low decreases the range proportionately.
