CHAPTER
Getting to Know Your NBG318S
This chapter introduces the main features and applications of the NBG318S.
1.1 Overview
The NBG318S is the ideal secure HomePlug AV wireless firewall router for all data passing
between the Internet and your local network.
1.1.1 Secure Broadband Internet Access
Connect a broadband modem to your NBG318S for shared Internet access protected by
firewall and content filtering. You can also use media bandwidth management to efficiently
manage traffic on your network. The Quality of Service (QoS) features allow you to prioritize
time-sensitive or highly important applications such as Voice over Internet (VoIP).
Figure 1
Secure Internet Access
1.1.2 Wireless LAN Application
The NBG318S Wireless LAN feature allows IEEE 802.11b or IEEE 802.11g compatible
wireless clients to access the Internet or the local network as well as to communicate with each
other. Wireless stations can move freely anywhere in the coverage area and use resources on
the wired network. The Super G function allows compatible clients to connect to the
NBG318S at up to 108 Mbps.

Chapter 1 Getting to Know Your NBG318S
Figure 2 WLAN Application Example
1.1.3 HomePlug AV
Connect to other HomePlug AV compatible devices through your home electrical wiring. A
HomePlug AV network is capable of up to 200Mbps data transfer without the need for
network cables.
Figure 3 HomePlug AV Internet Connection Example
1.2 Ways to Manage the NBG318S
Use any of the following methods to manage the NBG318S.
• Web Configurator. This is recommended for everyday management of the NBG318S
using a (supported) web browser.
32
NBG318S User’s Guide
Chapter 1 Getting to Know Your NBG318S
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
1.3 Good Habits for Managing the NBG318S
Do the following things regularly to make the NBG318S more secure and to manage the
NBG318S 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 NBG318S to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the NBG318S. You could simply restore your last configuration.

CHAPTER
Wireless Tutorial
This chapter gives you examples of how to set up an access point and wireless client for
wireless communication using the following parameters. The wireless clients can access the
Internet through an AP wirelessly.
2.1 Example Parameters
SSID
SSID_Example3
Channel
Security
WPA-PSK
(Pre-Shared Key: ThisismyWPA-PSKpre-sharedkey)
802.11 mode
IEEE 802.11b/g
An access point (AP) or wireless router is referred to as an “AP” and a computer with a
wireless network card or USB/PCI adapter is referred to as a “wireless client” here.
We use the M-302 utility screens as an example for the wireless client. The screens may vary
for different models.
2.2 Configuring the AP
Flow the steps below to configure the wireless settings on your AP.
1 Open the Wireless LAN > General screen in the AP’s web configurator.

6 Click the WLAN Station Status hyperlink in the AP’s Status screen. You can see if any
wireless client has connected to the AP.
Figure 7 AP: Status: WLAN Station Status
2.3 Configuring the Wireless Client
This section describes how to connect the wireless client to a network.
2.3.1 Connecting to a Wireless LAN
The following sections show you how to join a wireless network using the ZyXEL utility, as in
the following diagram. The wireless client is labelled C and the access point is labelled AP.
There are three ways to connect the client to an access point.
• Configure nothing and leave the wireless client to automatically scan for and connect to
any available network that has no wireless security configured.
• Manually connect to a network.
• Configure a profile to have the wireless client automatically connect to a specific network
or peer computer.
This example illustrates how to manually connect your wireless client to an access point (AP)
which is configured for WPA-PSK security and connected to the Internet. Before you connect
to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared
key. In this example, the SSID is “SSID_Example3” and the pre-shared key is
“ThisismyWPA-PSKpre-sharedkey”.

2.3.2 Creating and Using a Profile
A profile lets you automatically connect to the same wireless network every time you use the
wireless client. You can also configure different profiles for different networks, for example if
you connect a notebook computer to wireless networks at home and at work.
This example illustrates how to set up a profile and connect the wireless client to an access
point configured for WPA-PSK security. In this example, the SSID is “SSID_Example3”, the
profile name is “PN_Example3” and the pre-shared key is “ThisismyWPA-PSKpresharedkey”. You have chosen the profile name “PN_Example3”.

4.4.2 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).
NBG318S User’s Guide
61
Chapter 4 Connection Wizard
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 NBG318S (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the NBG318S does that
part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.
Refer to the appendix for more information on PPPoE.

4.4.5 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated
from the Internet, for instance, only between your two branch offices, you can assign any IP
addresses to the hosts without problems. However, the Internet Assigned Numbers Authority
(IANA) has reserved the following three blocks of IP addresses specifically for private
networks.
Table 17 Private IP Address Ranges
64
10.0.0.0
10.255.255.255
172.16.0.0
172.31.255.255
192.168.0.0
192.168.255.255
NBG318S User’s Guide
Chapter 4 Connection Wizard
You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the
ISP can provide you with the Internet addresses for your local networks. On the other hand, if
you are part of a much larger organization, you should consult your network administrator for
the appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
4.4.6 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do computers on a
LAN share one common network number.
Where you obtain your network number depends on your particular situation. If the ISP or
your network administrator assigns you a block of registered IP addresses, follow their
instructions in selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single
user account and the ISP will assign you a dynamic IP address when the connection is
established. The Internet Assigned Number Authority (IANA) reserved this block of addresses
specifically for private use; please do not use any other number unless you are told otherwise.
Let's say you select 192.168.1.0 as the network number; which covers 254 individual
addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the
first three numbers specify the network number while the last number identifies an individual
computer on that network.
Once you have decided on the network number, pick an IP address that is easy to remember,
for instance, 192.168.1.1, for your NBG318S, but make sure that no other device on your
network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your NBG318S will
compute the subnet mask automatically based on the IP address that you entered. You don't
need to change the subnet mask computed by the NBG318S unless you are instructed to do
otherwise.
4.4.7 DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP address and
vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is
extremely important because without it, you must know the IP address of a computer before
you can access it.
The NBG318S can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet,
when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS
Server fields in the Wizard and/or WAN > Internet Connection screen.
NBG318S User’s Guide
65
Chapter 4 Connection Wizard
2 If the ISP did not give you DNS server information, leave the DNS Server fields set to
0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN > Internet
Connection screen for the ISP to dynamically assign the DNS server IP addresses.
4.4.8 WAN IP and DNS Server Address Assignment
The following wizard screen allows you to assign a fixed WAN IP address and DNS server
addresses.

System DNS Server Address Assignment (if applicable)
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 NBG318S uses a system DNS server (in the order you specify
here) to resolve domain names for DDNS and the time server.

CHAPTER
Wireless LAN
This chapter discusses how to configure the wireless network settings in your NBG318S. See
the appendices for more detailed information about wireless networks.
5.1 Wireless Network Overview
The following figure provides an example of a wireless network.
Figure 43 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B
are called wireless clients. The wireless clients use the access point (AP) to interact with other
devices (such as the printer) or with the Internet. Your NBG318S is the AP.
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.
NBG318S User’s Guide
73
Chapter 5 Wireless LAN
• 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.
Requirements
To add a wireless LAN to your existing network, make sure you have the following:
1 an access point (AP) or a router with the wireless feature
2 at least one wireless network card/adapter which varies according to your computer.
•
•
If you have a desktop, use either a wireless USB adapter or a wireless PCI adapter.
If you have a laptop, use either a wireless USB adapter or a wireless CardBus
card.
3 a RADIUS server only if you want to use IEEE802.1x, WPA or WPA2
To have two or more computers communicate with each other wirelessly without an AP or
wireless router, make sure you have the following:
1 two or more wireless network cards/adapters which vary according to your computers.
•
•
If you have a desktop, use either a wireless USB adapter or a wireless PCI adapter.
If you have a laptop, use either a wireless USB adapter or a wireless CardBus
card.
Setup Information
To set up your wireless network using an AP or wireless router, make sure your AP or wireless
router and wireless network card(s)/adapter(s) use the same following settings:
•
•
•

5.2 Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the
wireless network.
5.2.1 SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can
hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you
should change the default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices
to get the SSID. In addition, unauthorized devices can still see the information that is sent in
the wireless network.
5.2.2 MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC
address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002
or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate
User’s Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not
allowed to use the wireless network. If a wireless client is allowed to use the wireless network,
it still has to have the correct settings (SSID, channel, and security). If a wireless client is not
allowed to use the wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address to use the wireless network.
1.
Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks.
These kinds of wireless devices might not have MAC addresses.
2.
Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
NBG318S User’s Guide
75
Chapter 5 Wireless LAN
5.2.3 User Authentication
You can make every user log in to the wireless network before they can use it. This is called
user authentication. However, every wireless client in the wireless network has to support
IEEE 802.1x to do this.
For wireless networks, there are two typical places to store the user names and passwords for
each user.
• In the AP: this feature is called a local user database or a local database.
• In a RADIUS server: this is a server used in businesses more than in homes.
If your AP does not provide a local user database and if you do not have a RADIUS server,
you cannot set up user names and passwords for your users.
Unauthorized devices can still see the information that is sent in the wireless network, even if
they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless
users to get a valid user name and password. Then, they can use that user name and password
to use the wireless network.
Local user databases also have an additional limitation that is explained in the next section.
5.2.4 Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
The types of encryption you can choose depend on the type of user authentication. (See
Section 5.2.3 on page 76 for information about this.)
Table 22 Types of Encryption for Each Type of Authentication
Weakest
NO AUTHENTICATION
RADIUS SERVER
No Security
WPA
Static WEP
WPA-PSK
Strongest
WPA2-PSK
WPA2
For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2.
If users do not log in to the wireless network, you can choose no encryption, Static WEP,
WPA-PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you
do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless
network has two wireless clients. Device A only supports WEP, and device B supports WEP
and WPA. Therefore, you should set up Static WEP in the wireless network.
76
NBG318S User’s Guide
Chapter 5 Wireless LAN
It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it
is still possible for unauthorized devices to figure out the original information
pretty quickly.
It is not possible to use WPA-PSK, WPA or stronger encryption with a local
user database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select WPA2 or WPA2-PSK in your NBG318S, you can also select an option
(WPA Compatible) to support WPA as well. In this case, if some wireless clients support
WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the
type of wireless network login) and select the WPA Compatible option in the NBG318S.
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every wireless client in the wireless network must
have the same key.
5.3 Roaming
A wireless station is a device with an IEEE 802.11a/b/g compliant wireless interface. An
access point (AP) acts as a bridge between the wireless and wired networks. An AP creates its
own wireless coverage area. A wireless station can associate with a particular access point
only if it is within the access point’s coverage area.
In a network environment with multiple access points, wireless stations are able to switch from
one access point to another as they move between the coverage areas. This is known as
roaming. As the wireless station moves from place to place, it is responsible for choosing the
most appropriate access point depending on the signal strength, network utilization or other
factors.
The roaming feature on the access points allows the access points to relay information about
the wireless stations to each other. When a wireless station moves from a coverage area to
another, it scans and uses the channel of a new access point, which then informs the other
access points on the LAN about the change. An example is shown in Figure 44 on page 78.
With roaming, a wireless LAN mobile user enjoys a continuous connection to the wired
network through an access point while moving around the wireless LAN.
Enable roaming to exchange the latest bridge information of all wireless stations between APs
when a wireless station moves between coverage areas. Wireless stations can still associate
with other APs even if you disable roaming. Enabling roaming ensures correct traffic
forwarding (bridge tables are updated) and maximum AP efficiency. The AP deletes records
of wireless stations that associate with other APs (Non-ZyXEL APs may not be able to
perform this). 802.1x authentication information is not exchanged (at the time of writing).
NBG318S User’s Guide
77
Chapter 5 Wireless LAN
Figure 44 Roaming Example
The steps below describe the roaming process.
1 Wireless station Y moves from the coverage area of access point AP 1 to that of access
point AP 2.
2 Wireless station Y scans and detects the signal of access point AP 2.
3 Wireless station Y sends an association request to access point AP 2.
4 Access point AP 2 acknowledges the presence of wireless station Y and relays this
information to access point AP 1 through the wired LAN.
5 Access point AP 1 updates the new position of wireless station Y.
5.3.1 Requirements for Roaming
The following requirements must be met in order for wireless stations to roam between the
coverage areas.
1 All the access points must be on the same subnet and configured with the same ESSID.
2 If IEEE 802.1x user authentication is enabled and to be done locally on the access point,
the new access point must have the user profile for the wireless station.
3 The adjacent access points should use different radio channels when their coverage areas
overlap.
4 All access points must use the same port number to relay roaming information.
5 The access points must be connected to the Ethernet and be able to get IP addresses from
a DHCP server if using dynamic IP address assignment.
5.4 Quality of Service
This section discusses the Quality of Service (QoS) features available on the NBG318S.
78
NBG318S User’s Guide
Chapter 5 Wireless LAN
5.4.1 WMM QoS
WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless
networks. It controls WLAN transmission priority on packets to be transmitted over the
wireless network.
WMM QoS prioritizes wireless traffic according to delivery requirements. WMM QoS is a
part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.
On APs without WMM QoS, all traffic streams are given the same access priority to the
wireless network. If the introduction of another traffic stream creates a data transmission
demand that exceeds the current network capacity, then the new traffic stream reduces the
throughput of the other traffic streams.
The NBG318S uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q tag
or DSCP information in each packet’s header. The NBG318S automatically determines the
priority to use for an individual traffic stream. This prevents reductions in data transmission
for applications that are sensitive to latency (delay) and jitter (variations in delay).
5.4.1.1 WMM QoS Priorities
The following table describes the WMM QoS priority levels that the NBG318S uses.
Table 23 WMM QoS Priorities
PRIORITY LEVEL
DESCRIPTION
voice
(WMM_VOICE)
Typically used for traffic that is especially sensitive to jitter. Use this priority
to reduce latency for improved voice quality.
video
(WMM_VIDEO)
Typically used for traffic which has some tolerance for jitter but needs to be
prioritized over other data traffic.
best effort
(WMM_BEST_EFFORT)
Typically used for traffic from applications or devices that lack QoS
capabilities. Use best effort priority for traffic that is less sensitive to latency,
but is affected by long delays, such as Internet surfing.
background
(WMM_BACKGROUND)
This is typically used for non-critical traffic such as bulk transfers and print
jobs that are allowed but that should not affect other applications and users.
Use background priority for applications that do not have strict latency and
throughput requirements.
