Do not overload outlets or extension cords, as this can result in a risk of fire or electric
shock. Overloaded electrical outlets, extension cords, frayed power cords, damaged or
cracked wire insulation, and broken plugs are dangerous. They may result in a shock or fire
hazard.
Route power supply cords so that they are not likely to be walked on or pinched by items
placed upon or against them. Pay particular attention to cords where they are attached to
plugs and convenience receptacles, and examine the point where they exit from the
device.
Place this device in a location that is close enough to an electrical outlet to accommodate

Installing the Gateway
Caution: 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.
Connect the SBG6782-AC to Your Computer
Before installing the SBG6782-AC:
Check with your service provider to ensure broadband cable service is available in your
area.
To set up a wireless network, you will need a high-speed Internet connection provided by
an Internet service provider.
Note: When contacting your service provider, you may need your gateway information
listed on the gateway label located on the bottom of your SBG6782-AC (see Gateway Label
("Gateway Label" page 16)).
Choose a location in your home where your computer and gateway are preferably near
existing cable and electrical wall outlets.
For the best Wi-Fi coverage, a central location in your home or building is recommended.
Note: The following installation procedure covers the wired Ethernet connection process so
that you can confirm that the SBG6782-AC was properly installed and can connect to the
Internet.

Figure 3: SBG6782-AC Connection Diagram
1. Check that a coaxial cable is already connected to a cable wall outlet or RF splitter
(optional).
2. Connect the other end of the coaxial cable to the Cable connector on the rear of the
SBG6782-AC.
Use your hand to tighten the connectors to avoid damaging them.
3. Connect the Ethernet cable to an available Ethernet port on the rear of the SBG6782-AC.
4. Connect the other end of the Ethernet cable to the Ethernet port on your computer.
Optional: Repeat steps 3 and 4 for an additional computer or other network device that
you want to install as a wired connection on your home network.
5. Connect the power cord to the Power port on the rear of the SBG6782-AC.
6. Plug the other end of the power cord into an electrical wall outlet that is not controlled by
a wall switch.
Note: This automatically powers ON the SBG6782-AC.
Establish an Internet Connection
Although your computer may already be configured to automatically access the Internet, you
should still perform the following gateway connectivity test to verify that the devices were
connected properly.
1. Power ON the computer connected to the SBG6782-AC, if it is turned off, and then log in.
2. Contact your service provider to activate (provision) the SBG6782-AC. You may have to
provide the HFC MAC ID listed on the gateway label.

light up in sequential order. See Product Overview for additional LED status information.
If all four LEDs did not light up solid and you also do not have an Internet connection,
you may have to contact your service provider to reactivate the SBG6782-AC or check
for signal issues.
If you still cannot connect to the Internet, the SBG6782-AC may be defective. Please
call ARRIS Technical Support at 1-877-466-8646 for assistance.
Connect Your MoCA Devices
You can also connect any MoCA devices, such as a Smart TV, to the SBG6782-AC. You will need

Launch the SBG6782-AC Quick Start Wizard
The SBG6782-AC Quick Start Wizard is a seven-step application to help you quickly customize
the default wireless network settings on your SBG6782-AC. The wizard configures your
SBG6782-AC wireless network name (SSID), Wi-Fi Security Key (network password), and Wi-Fi
Security mode.
IMPORTANT NOTE: The quick start wizard uses the default settings already configured
for your SBG6782-AC to help you quickly set up your wireless home network. However,
the wizard will only let you change the wireless network name (SSID) and Wi-Fi
Security Key (network password). After completing the wizard and getting your
SBG6782-AC connected to the Internet, you will be able to make additional network
configuration changes to further customize your wireless home network and connect
your wireless devices. See Configuring Your Wireless Network for more information.
