1.1 Overview
This chapter introduces the main features and applications of the NBG2105.
The NBG2105 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.
1.2 Applications
CHAPTER 1
Introduction
Your can have the following networks using the NBG2105:
• Wired. You can connect network devices via the Ethernet ports of the NBG2105 so that they can
communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG2105 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.
1.3 Ways to Manage the NBG2105
Use any of the following methods to manage the NBG2105.
• 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 NBG2105 using a
(supported) web browser.
1.4 Good Habits for Managing the NBG2105
Do the following things regularly to make the NBG2105 more secure and to manage the NBG2105
more effectively.
NBG2105 User’s Guide13
Chapter 1 Introduction
• 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 NBG2105 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG2105.
You could simply restore your last configuration.
1.5 Resetting the NBG2105
If you forget your password or IP address, or you cannot access the Web Configurator, you will need
to use the RESET button on the underside of the NBG2105 to reload the factory-default
configuration file. This means that you will lose all configurations that you had previously saved, the
password and the IP address will be reset to the defaults shown on the cover of this user’s guide.
1.5.1 How to Use the RESET Button
1Make sure the power LED is on.
2Press the RESET button for longer than five seconds (when the power LED begins to blink) and
release it to set the NBG2105 back to its factory-default configurations.
1.6 The WPS Button
Your NBG2105 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.
You can use the WPS button 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 WPSbutton for less than two seconds and release it. Press the WPS button on another
WPS-enabled device within range of the NBG2105.
14
NBG2105 User’s Guide
Note: You must activate WPS in the NBG2105 and in another wireless device within two
minutes of each other.
For more information on using WPS, see Section 8.2 on page 59.
1.7 The Clone MAC Button
Your NBG2105 can clone the MAC address of the computer connected to the NBG2105. It is
recommended that you clone the MAC address prior to hooking up the WAN port or connecting to
an AP or wireless router with Internet access.
Note: MAC cloning is supported only when the NBG2105 is in Router mode.
1.7.1 Cloning a computer's MAC address
1Make sure the power LED is on (not blinking).
2To copy and use the MAC address of a currently connected computer through a wired Ethernet or
wireless LAN connection, press the Clone MAC button for two to five seconds and release it.
Chapter 1 Introduction
3The WPS/MAC Clone LED turns on when the clone was successful.
4The NBG2105 restarts automatically ten seconds after you press the Clone MAC button.
1.7.2 Restoring the default MAC address
1Make sure the power LED is on (not blinking).
2Press and hold the Clone MAC button for more than five seconds to reset the NBG2105 back to the
factory default MAC address. The Clone MAC Address in the WAN screen shows 000000000000 to
indicate the NBG2105 is using the factory default MAC address.
3The NBG2105 restarts after you press the Clone MAC button.

3.2 What You Can Do
• Router mode connects the local network to another network, like the Internet. See Section 3.3
on page 21 for details of this mode.
• Access Point mode extends your network by allowing network devices to connect to the
NBG2105 wirelessly. See Section 3.4 on page 24 for details of this mode.
• Client mode enables the NBG2105 to be a wireless client to an upstream AP.
See Section 3.5 on page 27 for details of this mode.
• WISP + UR mode enables the NBG2105 to connect your local network to the Internet through
an ISP’s access point. UR provides Wi-Fi functionality to clients on the LAN side. See Section 3.6
on page 29 for details of this mode.
CHAPTER 3
Operation Modes
Note: Choose your operation mode carefully to avoid having to change it later. If you
select the incorrect operation mode you may not be able to connect to the Internet.
When changing to another mode, the IP address of the NBG2105 changes. The
running applications and services of the network devices connected to the
NBG2105 can be interrupted.
Note: In WISP + UR and Client modes, you should know the SSID and wireless security
details of the access point to which you want to connect.
3.3 Router Mode
A router connects your local network with another network, such as the Internet. The router has
two IP addresses, the LAN IP address and the WAN IP address. This mode offers services such as a
firewall, QoS or DDNS.

WISP+UR
Access Point
In WISP (Wireless ISP) + UR (Universal Repeater) mode, your NBG2105 can act as a wireless client
to wirelessly connect to the Internet or an existing network via an access point. In addition, it can
provide Wi-Fi function to the clients on the LAN side. Use this mode if you want to wirelessly
connect to the Internet or have an access point or wireless router in your network. In WISP + UR
mode, the IP address of the device on the local network is 192.168.1.2.
Note: Make sure your network and the remote network are NOT in the same subnet. If
the access point or wireless router is using 192.168.1.x, the NBG2105 in WISP +
UR mode needs to use something else, say 192.168.2.x.
Note: When the NBG2105 is in WISP + UR mode, you still need to enter your ISP
information in the WAN screen in order to access the Internet.
In the example below, one NBG2105 is configured as WISP +UR mode (A) and another is used as
an access point (B). The NBG2105 (A) wirelessly connects to the available access point (B), and
can allow the clients (x and y) to access the network through it using a wireless connection.
