Chapter 1 Introduction

Use a (supported) web browser to manage the NBG6615. Menus vary according to which mode you’re using.

Router Mode		AP Mode

See Chapter 4 on page 28 for more information on these modes.

1.2 Securing the NBG6615

Do the following things regularly to make the NBG6615 more secure and to manage the NBG6615 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 NBG6615 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG6615. You could simply restore your last configuration.

1.4 The WPS Button

Your NBG6615 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.

NBG6615’s User’s Guide

13

Chapter 1 Introduction

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 (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 button is located at the front panel of the NBG6615.

1.4.1 Using the WPS Button

1Make sure the power LED is on.

2Press the WPS button within 3 seconds to turn on the WPS function For more information on using WPS, see Section 5.3 on page 39.

1.5Reboot/Reset Button

Your NBG6615 has a recessed reboot/reset button on its back panel. To reboot, press the button with a paper clip or similar object for 3 to 5 seconds. To reset the NBG6615 to factory defaults, press for longer than 10 seconds.

1.6 Wall Mounting

You may need screw anchors if mounting on a concrete or brick wall.

Table 2 Wall Mounting Information

Distance between holes	10.50 cm
M4 Screws	Two
Screw anchors (optional)	Two

Figure 3 Screw Specifications

NBG6615’s User’s Guide

14

Chapter 1 Introduction

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 NBG6615 with the connection cables.

5Align the holes on the back of the NBG6615 with the screws on the wall. Hang the NBG6615 on the screws.

CHAPTER 2

The Web Configurator

2.1 Overview

This chapter describes how to access the NBG6615 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 NBG6615 via Internet browser. Use Internet Explorer 8.0 and later versions, Mozilla Firefox, Google Chrome or Safari. The recommended screen resolution is 1366 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.

2.2Accessing the Web Configurator

1Make sure your NBG6615 hardware is properly connected and prepare your computer or computer network to connect to the NBG6615 (refer to the Quick Start Guide).

2Launch your web browser.

3When the NBG6615 is in router mode, type "http://192.168.212.1" as the website address in your web browser. 192.168.212.1 is the default LAN IP address in router mode (the default device mode). (The default IP address in AP 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 NBG6615 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 192.168.212.3 and 192.168.212.254 (see Appendix C on page 157).

4Type admin (default) as the user name and 1234 (default) as the password and click OK.

2.3 Resetting the NBG6615

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 NBG6615 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 admin and password will be reset to 1234. The IP address in router mode will be reset to “192.168.212.1”.

Connection	Select Static IP to give the NBG6615 a fixed, unique IP address.
Type
IP Address	Select this option if you were given IP address and/or DNS server settings by the ISP. The fixed IP
	address should be in the same subnet as your broadband modem or router.
Subnet Mask	Enter the subnet mask address in this field.
Default	Enter the gateway IP address provided by your ISP.
Gateway
DNS	DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and
	vice versa. The DNS server is extremely important because without it, you must know the IP
	address of a computer before you can access it. The NBG6615 uses a system DNS server (in the
	order you specify here) to resolve domain names for DDNS and the time server. Enter the DNS
	server’s IP address in this field.

3.1.3 PPPoE Connection

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 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 NBG6615 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6615 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

3.1.4 PPTP Connection

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based networks.

PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such as the Internet.

	to access the network.
Channel Width	Select whether the NBG6615 uses a wireless channel width of 20MHz, 40MHz, or 80 MHz
	(available with 5G only). Select Auto to allow the NBG6615 to adjust the channel bandwidth
	depending on network conditions.
	Select 20 MHz if you want to lessen radio interference with other wireless devices in your
	neighborhood or the wireless clients do not support channel bonding.
	Select 40 MHz if your 2.4G to bond two adjacent radio channels to increase throughput. The
	wireless clients must also support 40 MHz.
	Select 80MHz (available for 5G only) if you have a network with only a few wireless clients.

4.2 Setting your NBG6615 to Router Mode

The NBG6615 is set to wireless router mode by default. If it was changed and now you want to set it back, do the following procedure.

1Connect your computer to the LAN port of the NBG6615.

2The default LAN IP address of the NBG6615 is 192.168.212.1 in router mode and 192.168.1.2 by default in Access Point mode. In router mode, the NBG6615 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 192.168.212.3 and 192.168.212.254.

3After you’ve set your computer’s IP address, open a web browser such as Internet Explorer and type the IP address of the NBG6615 as the web address in your web browser.

4Log into the Web Configurator. See the Chapter 2 on page 16 for instructions on how to do this.

5Go to Maintenance > Sys OP Mode > General and select Router.
