NBG5615 User’s Guide 15
CHAPTER 1
Introduction
1.1 Overview
This chapter introduces the main features and applications of the NBG5615.
The NBG5615 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 compatible devices. The NBG5615 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 are two USB 2.0 ports on the side panel of your NBG5615. You can connect USB (version 2.0
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG5615
automatically detects the USB devices.
Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB
storage devices (such as memory sticks, USB hard drives) and/or USB devices
(such as USB printers). Other USB products are not guaranteed to function
properly with the NBG5615.
Note: Be sure to install the ZyXEL NetUSBTM Share Center Utility (for NetUSB
functionality) from the included disc, or download the latest version from the
zyxel.com website.
1.2 Applications
Your can have the following networks using the NBG5615:
•Wired. You can connect network devices via the Ethernet ports of the NBG5615 so that they can
communicate with each other and access the Internet.
•Wireless. Wireless clients can connect to the NBG5615 to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-
compatible device.
•WAN. Connect to a broadband modem/router for Internet access.
•NetUSB. The NBG5615 allows you to connect a USB device (such as printer, or scanner) directly
to the USB port and then share that device over the network using the NetUSB utility.

Chapter 1 Introduction
NBG5615 User’s Guide

1.3 Ways to Manage the NBG5615
Use any of the following methods to manage the NBG5615.
• WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web
Configurator to set up a wireless network with your ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the NBG5615 using a
(supported) web browser.
1.4 Good Habits for Managing the NBG5615
Do the following things regularly to make the NBG5615 more secure and to manage the NBG5615
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 NBG5615 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG5615.
You could simply restore your last configuration.
1.5 Resetting the NBG5615
If you forget your password or IP address, or you cannot access the Web Configurator, you will need
to use the RESET button at the back of the NBG5615 to reload the factory-default configuration
file. This means that you will lose all configurations that you had previously saved, the password
will be reset to “1234” and the IP address will be reset to “192.168.1.1”.
1.5.1 How to Use the RESET Button
1Make sure the power LED is on.
2Press the RESET button for one to four seconds to restart/reboot the NBG5615.
3Press the RESET button for longer than five seconds to set the NBG5615 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG5615 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.

Chapter 1 Introduction
NBG5615 User’s Guide 17
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 ( ) on the front panel of the NBG5615 to activate WPS in order to
quickly set up a wireless network with strong security.
1Make sure the power LED is on (not blinking).
2Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the NBG5615.
Note: You must activate WPS in the NBG5615 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 9.2 on page 73.

1.8 Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.
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 NBG5615 with the
connection cables.
5Align the holes on the back of the NBG5615 with the screws on the wall. Hang the NBG5615 on the
screws.
2.4G/5G WLAN Green On The NBG5615 is ready and the 2.4GHz/5GHz wireless LAN is on,
but is not sending/receiving data through the wireless LAN.
Blinking The NBG5615 is sending/receiving data through the wireless
LAN.
Off The wireless LAN is not ready or has failed.
