1.1 Overview
This chapter introduces the main features and applications of the NBG4615 v2.
The NBG4615 v2 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
802.11b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
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.
CHAPTER 1
Introduction
1.2 Applications
Your can have the following networks using the NBG4615 v2:
• Wired. You can connect network devices via the Ethernet ports of the NBG4615 v2 so that they
can communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG4615 v2 to access network resources. You can
use WPS (WiFi Protected Setup) to create an instant network connection with another WPScompatible device.
• WAN. Connect to a broadband modem/router for Internet access.
• NetUSB. The NBG4615 v2 allows you to connect a USB device (such as printer, scanner, or
portable hard disk) directly to the USB port and then share that device over the network.
1.3 W ays to Manage the NBG4615 v2
Use any of the following methods to manage the NBG4615 v2.
• 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 NBG4615 v2 using a
(supported) web browser.
NBG4615 v2 User’s Guide15
Chapter 1 Introduction
1.4 Good Habits for Managing the NBG4615 v2
Do the following things regularly to make the NBG4615 v2 more secure and to manage the
NBG4615 v2 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 NBG4615 v2 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG4615
v2. You could simply restore your last configuration.
1.5 Resetting the NBG4615 v2
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 NBG4615 v2 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 NBG4615 v2.
3Press the RESET button for longer than five seconds to set the NBG4615 v2 back to its factory-
default configurations.
1.6 The WPS Button
Your NBG4615 v2 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure
wireless network. WPS is an industry standard specification, defined by the WiFi 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.
16
You can use the WPS button () on the front panel of the NBG4615 v2 to activate WPS in order
to quickly set up a wireless network with strong security.
