1.3 Ways to Manage the NBG-419N

Use any of the following methods to manage the NBG-419N.
• Web Configurator. This is recommended for everyday management of the NBG­419N using a (supported) web browser.
• Wireless switch. You can use the built-in switch of the NBG-419N to turn the wireless function on and off without opening the Web Configurator.
• WPS (Wi-Fi Protected Setup) button. You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your ZyXEL Device.

1.4 Good Habits for Managing the NBG-419N

Do the following things regularly to make the NBG-419N more secure and to manage the NBG-419N 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 NBG-419N to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG-419N. You could simply restore your last configuration.

2.3 Connect to Internet

The NBG-419N offers five Internet connection types. They are Static IP, DHCP, PPPoE, PPTP or L2TP. The wizard attempts to detect which WAN connection
type you are using.
Figure 4 Detecting your Internet Connection Type
If the wizard does not detect a connection type, you must select one from the drop-down list box. Check with your ISP to make sure you use the correct type.
Note: If you get an error message, check your hardware connections. Make sure your
Internet connection is up and running.
The following screen depends on your Internet connection type. Enter the details provided by your Internet Service Provider (ISP) in the fields (if any).

2.3.3 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host

NBG-419N User’s Guide
Chapter 2 Connection Wizard
personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks.
For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS).
One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/ carrier, as it requires no specific configuration of the broadband modem at the subscriber's site.
By implementing PPPoE directly on the NBG-419N (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG-419N does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

WISP Mode

9.1 Overview

Your NBG-419N can act as a wireless client. In wireless client mode, it can connect to an existing network via an access point. Use this mode if you already have an access point or router in your network.
In the example below, one NBG-419N (A) is configured as a wireless client and another is used as an access point (B). The wireless client has two clients that need to connect to the Internet. The NBG-419N wirelessly connects to the available access point (B).
Figure 48 Wireless Client Mode
WISP
built-in firewall
After the NBG-419N and the access point connect, the NBG-419N acquires its WAN IP address from the access point. The clients of the NBG-419N can now surf the Internet.

Figure 57 Wireless Access Point Connection to the Internet

10.3 Configuring Wireless Security Using WPS

This section gives you an example of how to set up wireless network using WPS. This example uses the NBG-419N as the AP and NWD210N as the wireless client which connects to a notebook.
NBG-419N User’s Guide
89
Chapter 10 Tutorials
Note: The wireless client must be a WPS-aware device (for example, a WPS USB
adapter or PCI card).
There are two WPS methods for creating a secure connection. This tutorial shows you how to do both.
• Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 10.3.1 on page 90.This is the easier method.
• PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NBG-419N’s interface. See Section 10.3.2 on page 91. This is the more secure method, since one device can authenticate the other.
10.3.1 Push Button Configuration (PBC)
1 Make sure that your NBG-419N is turned on and that it is within range of your
computer.
2 Make sure that you have installed the wireless client (this example uses the
NWD210N) driver and utility in your notebook.
3 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS
button (Start or WPS button)
4 Log into NBG-419N’s Web Configurator and press the Push Button button in the
Network > Wireless Client > WPS Station screen.
Note: Your NBG-419N has a WPS button located on its panel, as well as a WPS
button in its configuration utility. Both buttons have exactly the same function; you can use one or the other.
Note: It doesn’t matter which button is pressed first. You must press the second
button within two minutes of pressing the first one.
The NBG-419N sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG-419N securely.

11.2 What You Can Do

•Use the General screen (Section 11.4 on page 103) to enable the Wireless LAN, enter the SSID and select the wireless security mode.
•Use the MAC Filter screen (Section 11.5 on page 109) to allow or deny wireless stations based on their MAC addresses from connecting to the NBG-419N.
•Use the Advanced screen (Section 11.6 on page 110) to allow wireless advanced features, such as intra-BSS networking and set the RTS/CTS Threshold.
•Use the QoS screen (Section 11.7 on page 111) to set priority levels to services, such as e-mail, VoIP, chat, and so on.
•Use the WPS screen (Section 11.8 on page 112) to quickly set up a wireless network with strong security, without having to configure security settings manually.
•Use the WPS Station screen (Section 11.9 on page 113) to add a wireless station using WPS.
•Use the Scheduling screen (Section 11.10 on page 114) to set the times your wireless LAN is turned on and off.
•Use the WDS screen (Section 11.11 on page 115) to configure Wireless Distribution System on your NBG-419N.

11.3 What You Should Know

Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.
11.3.1 Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless network.
