This chapter introduces the main features and applications of the NBG7815, also called ARMOR G5. It
has four 1 Gbps Ethernet LAN ports, one 10G multi-gigabit LAN port, and one 2.5G/1G WAN port.
The NBG7815 extends the range of your existing wired network without additional wiring, providing easy
network access to mobile users. You can set up a wireless network with other IEEE 802.11a/b/g/n/ac
compatible devices. The NBG7815 is able to function both 2.4GHz and 5GHz networks at the same time.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
There is an USB port on the side panel of your NBG7815. You can connect an USB memory stick, an USB
hard drive, or an USB device for file sharing. The NBG7815 automatically detects the USB device.
CHAPTER 1
Introduction
1.1.1 Multi-Gigabit
Some network devices such as gaming computers, servers, network attached storage (NAS) devices, or
access points may have network cards that are capable of 2.5 Gbps connectivity.
If these devices are connected to a 1 Gbps or 10 Gbps Ethernet port, they can only transmit or receive
up to 1 Gbps as speeds of 10 Gbps cannot be attained. Moreover, if network devices with 10 Gbps
network cards are connected to a 10 Gbps Ethernet port, you must use Cat 6A or better Ethernet cables
to achieve 10 Gbps speeds. Most buildings, at the time of writing, use Cat 5e or Cat 6 Ethernet cables.
2.5 Gbps Multi-Gigabit (IEEE 802.3bz) Ethernet ports on the NBG7815 automatically allow connections
up to the speed of the connected network device (100 Mbps, 1 Gbps, 2.5 Gbps), and you just need to
use a Cat 5e or Cat 6 Ethernet cable.
1.2 Applications
Your can have the following networks with the NBG7815:
• Wired. You can connect network devices via the Ethernet ports of the NBG7815 so that they can
communicate with each other and access the Internet.

• Wireless. Wireless clients can connect to the NBG7815 to access network resources. You can use WPS
(Wi-Fi Protected Setup) to create an instant network connection with another WPS-compatible
device.

1.3 Ways to Manage the NBG7815
Use the following method to manage the NBG7815.
• Web Configurator. This is recommended for everyday management of the NBG7815 using a
(supported) web browser.
• Zyxel ARMOR. This is the app you can use to manage the NBG7815 on your cellphone. To install the
app, scan the QR code on the QSG.

Chapter 1 Introduction
1.4 Good Habits for Managing the NBG7815
Do the following things regularly to make the NBG7815 more secure and to manage the NBG7815 more
effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different types of
characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the device becomes unstable or even crashes. If you forget your
password, you will have to reset the NBG7815 to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the NBG7815. You could simply
restore your last configuration.
1.5 Resetting the NBG7815
If you forget your password or IP address, or you cannot access the Web Configurator, insert a thin
object into the Reset hole on the side of the NBG7815 to reload the factory-default configuration file.
This means that you will lose all settings that you had previously saved.
1.5.1 How to Use the RESET Button
1Make sure the power LED is on.
2Locate the Reset hole.
3Insert a thin object into the Reset hole for longer than eight seconds to reset the NBG7815 back to its
factory-default configuration.
1.6 The WPS Button
Your NBG7815 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure wireless
network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Each WPS connection works between two devices. Both devices must
support WPS (check each device’s documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to
authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set up
a secure network by themselves.
You can use the WPS button in the Web Configurator of the NBG7815 to activate WPS in order to quickly
set up a wireless network with strong security.

1Select a position free of obstructions on a wall strong enough to hold the weight of the device.
2Mark two holes on the wall at the appropriate distance apart for the screws.
Be careful to avoid damaging pipes or cables located inside the wall when
drilling holes for the screws.
3If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the full
depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way in - leave
a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the screws all
the way in - leave a gap of about 0.5 cm.
4Make sure the screws are fastened well enough to hold the weight of the NBG7815 with the connection
cables.
5Remove the rubber feet.
6Align the holes on the back of the NBG7815 with the screws on the wall. Hang the NBG7815 on the
screws.
