1.1 Overview
This chapter introduces the main features and applications of the Router.
The Router upgrades the speed of your existing wireless network, providing faster network access
to mobile users. Making use of IEEE 802.11AC technology, it not only upgrades your network to the
next level but also eliminates dead spots, while offering backward compatibility 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. You can use media bandwidth management to efficiently manage traffic on your
network. Bandwidth management features allow you to prioritize time-sensitive or highly important
applications such as Voice over the Internet (VoIP).
CHAPTER 1
Getting to Know Your Router
1.2 Applications
Your can create the following networks using the Router:
• Wired. You can connect network devices via the Ethernet ports of the Router so that they can
communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the Router to access network resources.
• WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the Router
Use any of the following methods to manage the Router.
• Web Configurator. This is recommended for everyday management of the Router using a
(supported) web browser.
• Wireless switch. You can use the built-in switch of the Router 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 Router.
NBG6503 User’s Guide15
Chapter 1 Getting to Know Your Router
1.4 Good Habits for Managing the Router
Do the following things regularly to make the Router more secure and to manage the Router 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 Router to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the Router. You
could simply restore your last configuration.

1.6 The WPS Button
Your Router 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).

2.4 GHz band.
OffThe wireless LAN 2.4 GHz band is not ready or has failed.
BlinkingThe Router is negotiating a WPS connection with a wireless
client.
OffThe wireless LAN is not ready or has failed.
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.
For more information on using WPS, see Section 9.3 on page 73.
1.7 Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.

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 Router with the
connection cables.
5Align the holes on the back of the Router with the screws on the wall. Hang the Router on
the screws.

2.1 Overview
This chapter provides information on the wizard setup screens in the Web Configurator.
The Web Configurator’s wizard setup helps you configure your device to access the Internet. Refer
to your ISP for your Internet account information. Leave a field blank if you don’t have that
information.
2.2 Accessing the Wizard
Launch your web browser and type "http://192.168.1.1" as the website address. Type "1234"
(default) as the password and click Login.

2.3 Connect to Internet
The Router offers four Internet connection types. They are Static IP, DHCP, PPPoE, or PPTP. 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).

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 Router uses a system DNS
server (in the order you specify here) to resolve domain names for DDNS and the time
server.
Enter the primary DNS server's IP address in the fields provided.
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 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 Router (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the Router does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.

2.3.4 Connection Type: PPTP
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a
remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks.
Chapter 2 Connection Wizard
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks,
such as the Internet.
Refer to the appendix for more information on PPTP.
The Router supports one PPTP server connection at any given time.
