Chapter 2
Getting Started
The ARRIS SURFboard® SBR-AC1750 Wireless Router is a 3x3 dual-band 11ac router, allowing users to
connect to the Internet through a separate DOCSIS-compliant cable modem. With Qualcomm solution
and StreamBoost application to provide best throughput in different applications.
The SBR-AC1750 Wireless Router has the following features:
Remote management capability: allows you to make changes to your Wireless Router's
configuration from anywhere on the Internet.
Smart stream management: Qualcomm StreamBoostTM technology automatically gives
applications and devices the bandwidth they need for the best online experience
Convenience: supports Ethernet and 802.11a/b/g/n/ac wireless connections; both can be used
simultaneously
This guide provides a product overview and instructions for installing and configuring the
SBR-AC1750. It also includes procedures for setting up secure wireless network connections and
managing your SBR-AC1750 and network configurations.
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 Wireless Router. 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 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). 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 cable company may suspend your account to protect the rest of the network.
The SBR-AC1750 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 SBR-AC1750. 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 SBR-AC1750 through the Ethernet ports, you need an
Ethernet hub (available at computer retailers).
The Wireless Router 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 Wireless Router 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.
In the Box
Before installing the SBR-AC1750, check that the following items are included in the box. If any items
are missing, please call ARRIS Technical Support at 1-877-466-8646.

Installing the Router
This product is for indoor use only. Do not route the Ethernet cable(s)
outside of the building. Exposure of the cables to lightning could create a
safety hazard and damage the product.
There are a number of factors to consider when choosing a location to install your Wireless Router:
Is an AC outlet available nearby? For best results, the outlet should not be switched and should be
close enough to the Wireless Router that extension cords are not required.
Is the cable modem nearby? Can you easily run cables between the wireless router’s location and
the cable modem?
If you are connecting devices to the Ethernet ports, can you easily run cables between the Wireless
Router’s location and those devices?
If you want to mount the Wireless Router on a wall, does the location provide a solid surface for
secure attachment? For best results when mounting the Wireless Router on drywall, position the
Wireless Router so at least one of the screws are fastened to a stud. This may prevent the Wireless
Router from pulling out of the wall in the future.
If you want to install the Wireless Router 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 Wireless Router 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 Wireless Router so that:
Air flows freely around it.
The rear faces the nearest wall.
It will not fall to the floor if bumped or moved.
The sides of the unit are not blocked.
Cleaning Instructions

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
Wireless Router in the upper floor of a multi-story dwelling)
Decreases
range
Lowering the unit below the devices (for example, installing the
Wireless Router in a basement)
Metal or concrete walls between the Wireless Router and other
devices
Large metal appliances, aquariums, or metal cabinets between the
Wireless Router 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.

Configuring Your Ethernet Connection
If your computer is equipped with a LAN card providing an Ethernet connection, you may have to
configure your computer’s TCP/IP settings. The steps that follow will guide you through setting your
computer’s TCP/IP settings to work with the Wireless Router.
Requirements
Make sure you have the following before attempting to configure your Ethernet connection:
Computer with Ethernet interface
Ethernet cable (supplied)
IP address, subnet, gateway, and DNS information for installations not using DHCP
How to use this Chapter
The following list shows the procedures for modifying the TCP/IP settings on the computer. The
procedure is slightly different depending on the operating system that you are using. Please ensure
you are using the correct steps for the operating system on your computer. Follow the links below for
instructions to configure your Ethernet connection on your operating system.
TCP/IP Configuration for Windows XP (page 20)
TCP/IP Configuration for Windows Vista (page 21)
TCP/IP Configuration for Windows 7 or Windows 8 (page 21)
TCP/IP Configuration for MacOS X (page 22)
