CHAPTER 1
Introduc tion
1.1 O ve rvie w
The NBG-418N v2 extends the range of your existing wired network without additional wiring, providing
easy network access to mobile users.
Your can create the following connections using the NBG-418N v2:
•LAN. You can connect network devices via the Ethernet ports of the NBG-418N v2 so that they can
communicate with each other and access the Internet.
•WLAN. Wireless clients can connect to the NBG-418N v2 to access network resources.
•WAN. Connect to a broadband modem/router for Internet access.
Fig ure 1 NBG-418N v2 Network
You can set up the NBG-418N v2 with other IEEE 802.11b/g/n compatible devices in one of the following
device modes:
•Router
• Access Point
• Universal Repeater
• Client Bridge

Use a (supported) web browser to manage the NBG-418N v2. Menus vary according to which mode
you’re using.
See Chapter 4 on page 28 for more information on these modes.
1.2 Se c uring the NBG - 418N v2
Do the following things regularly to make the NBG-418N v2 more secure and to manage the NBG-418N
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 NBG-418N v2 to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the NBG-418N v2. You could
simply restore your last configuration.

1.3 LEDs
Fig ure 2 Front Panel
The following table describes the LEDs and the WPS button.
1.4 The WPS/ RESETButton
Your NBG-418N 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 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).
Table 1 Front Panel LEDs and WPS Button
LED COLO R STATUS DESCRIPTION
POWER Green On The NBG-418N v2 is receiving power and functioning properly.
Off The NBG-418N v2 is not receiving power.
WAN Green On The NBG-418N v2 has a successful 10/100MB WAN connection.
Blinking The NBG-418N v2 is sending/receiving data through the WAN.
Off The WAN connection is not ready, or has failed.
WLAN Green On The NBG-418N v2 is ready, but is not sending/receiving data through
the wireless LAN.
Blinking The NBG-418N v2 is sending/receiving data through the wireless LAN.
The NBG-418N v2 is negotiating a WPS connection with a wireless
client.
Off The wireless LAN is not ready or has failed.
WPS Green On WPS status is configured.
Blinking The NBG-418N v2 is negotiating a WPS connection with a wireless
client.
Off The WPS status is not configured or disabled.

Depending on the devices you have, you can either press a button (recommended) 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.
The WPS/ RESETsingle button is located at the back panel of the NBG-418N v2.
1.4.1 Using the WPS/ RESETButton
1Make sure the power LED is on.
2Press the WPS/ RESETbutton within 3 seconds to turn on the WPS function
3Press the WPS/ RESETbutton for longer than 10 seconds to restart/reboot the NBG-418N v2 back to its
factory-default configurations.
For more information on using WPS/ RESET, see Section 5.3 on page 46.
1.5 Wa ll Mo unting
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 c a re ful to a vo id da ma g ing pipe s or c a b le s lo c a te d inside the wa ll
whe n drilling hole s fo r the sc re ws.
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 NBG-418N v2 with the
connection cables.
5Align the holes on the back of the NBG-418N v2 with the screws on the wall. Hang the NBG-418N v2 on
the screws.

CHAPTER 2
The We b Config ura tor
2.1 O ve rvie w
This chapter describes how to access the NBG-418N v2 Web Configurator and provides an overview of
its screens.
The Web Configurator is an HTML-based management interface that allows easy setup and
management of the NBG-418N v2 via Internet browser. Use Internet Explorer 8.0 and later versions,
Mozilla Firefox, Google Chrome or Safari. The recommended screen resolution is 1024 by 768 pixels.
In order to use the Web Configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in
Windows XP SP (Service Pack) 2.
• JavaScript (enabled by default).
• Java permissions (enabled by default).
Refer to Chapter 23 Troubleshooting to see how to make sure these functions are allowed in Internet
Explorer.
2.2 Ac c e ssing the We b Configura tor
1Make sure your NBG-418N v2 hardware is properly connected and prepare your computer or computer
network to connect to the NBG-418N v2 (refer to the Quick Start Guide).
2Launch your web browser.
3When the NBG-418N v2 is in router mode, type “http://myrouter” or "http://192.168.1.1" as the website
address in your web browser. 192.168.1.1 is the default LAN IP address in router mode (the default
device mode). (The default IP address in non-router mode is 192.168.1.2).
Your computer must be in the same subnet in order to access this website address. In router mode, the
NBG-418N v2 can assign your computer an IP address, so you must set your computer to get an IP
address automatically (computer factory default) or give it a fixed IP address in the range between
192.168.1.3 and 192.168.1.254 (see the appendices).
4Type a dmin (default) as the user name and 1234 (default) as the password and click OK.

Note: The management session automatically times out when the time period set in the
Adm inistra to r Ina c tivity Tim e r field expires (default five minutes). Simply log back into
the NBG-418N v2 if this happens.
6Select the setup type you want to use.
• Click G o to Wiza rd Se tup to use the Configuration Wizard for basic Internet and Wireless setup.
• Click Go to Adva nc e d Se tup to view and configure all the NBG-418N v2’s settings.
• Select a language to go to the basic Web Configurator in that language. To change to the
advanced configurator see Chapter 22 on page 148.

Fig ure 6 Selecting the setup mode
2.3 Re se tting the NBG -418N v2
If you forget your password or IP address, or you cannot access the Web Configurator, you will need to
use the WPS/ RESETbutton at the back of the NBG-418N v2 to reload the factory-default configuration
file. This means that you will lose all configurations that you had previously saved, the username will be
reset to a dm in and password will be reset to 1234. The IP address will be reset to “192.168.1.1”.
Make sure the power LED is on and press the WPS/ RESETbutton for longer than 10 seconds to restart/
reboot and set the NBG-418N v2 back to its factory-default configurations.
