1.1 Overview
EMG refers to these models as outlined below.
• EMG6726-B10A
• EMG8726-B10A
The EMG is an Ethernet gateway providing triple-play services with optimized HD IPTV services for the
home or office. This model offers a Gigabit Ethernet (GbE) WAN port. The EMG offers 2.4G and 5G Wi-Fi
networks that can operate simultaneously.
The following table describes the feature difference of the EMG.

Only use firmware for your EMG’s specific model.
1.1.1 Internet Access
Your EMG has a Gigabit Ethernet port for super-fast Internet access. It provides Internet access by
connecting the WAN port to your ISP. Computers can connect to the EMG’s LAN ports (or wirelessly) and
access the Internet simultaneously.
You can also configure IP filtering on the EMG for secure Internet access. When the IP filter is on, all
incoming traffic from the Internet to your network is blocked by default unless it is initiated from your
network. This means that probes from the outside to your network are not allowed, but you can safely
browse the Internet and download files.
1.1.2 Ethernet WAN
If you have another broadband modem or router available, you can connect the WAN port to the
broadband modem or router. This way, you can access the Internet via an Ethernet connection and still
use the QoS, Firewall and parental control functions on the EMG.

Figure 1 EMG’s Internet Access Application: Ethernet WAN
1.1.3 Dual-Band
The EMG is a dual-band gateway that can use both 2.4G and 5G networks at the same time. You could
use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz band for time
sensitive traffic like high-definition video, music, and gaming.

1.1.4 Triple Play
Triple play means using broadband Internet access, VoIP and streaming video/audio media, all at the
same time with no noticeable loss in bandwidth.
Figure 3 Triple Play Example
Chapter 1 Introducing the EMG
Smart TV
1.1.5 Wireless Access
The EMG is a wireless Access Point (AP) for IEEE 802.11b/g/n/a/ac wireless clients, such as notebook
computers, iPads, smartphones, etc. These devices can connect to the EMG to access network
resources and the Internet.
Your EMG supports Wi-Fi Protected Setup (WPS), which allows you to quickly set up a wireless network
with strong security.
You can configure your wireless network using the built-in Web Configurator.
See Section 4.3 on page 40 for more information about how to set up a wireless network.

1.2 Ways to Manage the EMG
Use any of the following methods to manage the EMG.
EMG6726/8726-B10A User’s Guide
19
Chapter 1 Introducing the EMG
• Web Configurator. This is recommended for everyday management of the EMG using a (supported)
web browser.
1.3 Good Habits for Managing the EMG
Do the following things regularly to make the EMG more secure and to manage the EMG 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 EMG to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the EMG. You could simply restore your
last configuration.

4.5 Configuring Static Route for Routing to Another
Network
In order to extend your Intranet and control traffic flowing directions, you may connect a router to the
EMG’s LAN. The router may be used to separate two department networks. This tutorial shows how to
configure a static routing rule for two network routings.
In the following figure, router R is connected to the EMG’s LAN. R connects to two networks, N1
(192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in N1 network) to
computer B (in N2 network), the traffic is sent to the EMG’s WAN default gateway by default. In this
case, B will never receive the traffic.
You need to specify a static routing rule on the EMG to specify R as the router in charge of forwarding
traffic to N2. In this case, the EMG routes traffic from A to R and then R routes the traffic to B.

4.6 Configuring QoS Queue and Class Setup
This section contains tutorials on how you can configure the QoS screen.
Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic
because your task includes sending urgent updates to clients at least twice every hour. You also upload
data files (such as logs and e-mail archives) to the FTP server throughout the day. Your colleagues use
the Internet for research, as well as chat applications for communicating with other branch offices.
In the following figure, your Internet connection has an upstream transmission bandwidth of 10,000 kbps.
For this example, you want to configure QoS so that e-mail traffic gets the highest priority with at least
5,000 kbps. You can do the following:
• Configure a queue to assign the highest priority queue (1) to e-mail traffic going to the WAN
interface, so that e-mail traffic would not get delayed when there is network congestion.
• Note the IP address (192.168.1.23 for example) and/or MAC address (AA:FF:AA:FF:AA:FF for example)
of your computer and map it to queue 7.
Note: QoS is applied to traffic flowing out of the EMG.
Traffic that does not match this class is assigned a priority queue based on the internal QoS mapping
table on the EMG.
QoS Example
1 Click Network Setting > QoS > General and select Enable. Set your WAN Managed Upstream Bandwidth
to 10,000 kbps (or leave this blank to have the EMG automatically determine this figure). Click Apply.

4.7 Access the EMG Using DDNS
If you connect your EMG to the Internet and it uses a dynamic WAN IP address, it is inconvenient for you
to manage the device from the Internet. The EMG’s WAN IP address changes dynamically. Dynamic
DNS (DDNS) allows you to access the EMG using a domain name.
To use this feature, you have to apply for DDNS service at www.dyndns.org.
This tutorial covers:
• Registering a DDNS Account on www.dyndns.org
• Configuring DDNS on Your EMG
• Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.
4.7.1 Registering a DDNS Account on www.dyndns.org
1 Open a browser and type http://www.dyndns.org.
2 Apply for a user account. This tutorial uses UserName1 and 12345 as the username and password.
3 Log into www.dyndns.org using your account.
4 Add a new DDNS host name. This tutorial uses the following settings as an example.
• Hostname: zyxelrouter.dyndns.org
• Service Type: Host with IP address
• IP Address: Enter the WAN IP address that your EMG is currently using. You can find the IP address on
the EMG’s Web Configurator Status page.
Then you will need to configure the same account and host name on the EMG later.

WAN IP Address
The WAN IP address is an IP address for the EMG, which makes it accessible from an outside network. It is
used by the EMG to communicate with other devices in other networks. It can be static (fixed) or
dynamically assigned by the ISP each time the EMG tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS
server IP address(es).
IPv6 Introduction
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in
IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and supports IPv6 rapid deployment
(6RD).
38
IP addresses. The EMG
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an
example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So
2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be written as
2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double
colon can only appear once in an IPv6 address. So
2001:0db8:0000:0000:1a2f:0000:0000:0015 can be written as
2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
IPv6 Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6
prefix length specifies how many most significant bits (start from the left) in the address compose the
network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.
IPv6 Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into
eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character
(1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example,
FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.

Chapter 6 Broadband
IPv6 Rapid Deployment
Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network.
When the EMG has an IPv4 WAN address and you set IPv4/IPv6 Mode to IPv4 Only, you can enable 6rd
to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
The EMG generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the ISP’s
Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The local network can also
use IPv4 services. The EMG uses it’s configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet.
Figure 23 IPv6 Rapid Deployment
Dual Stack Lite
Use Dual Stack Lite when local network computers use IPv4 and the ISP has an IPv6 network. When the
EMG has an IPv6 WAN address and you set IPv4/IPv6 Mode to IPv6 Only, you can enable Dual Stack Lite
to use IPv4 computers and services.
The EMG tunnels IPv4 packets inside IPv6 encapsulation packets to the ISP’s Address Family Transition
Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also use IPv6 services.
The EMG uses it’s configured IPv6 WAN IP to route IPv6 traffic to the IPv6 Internet.

6.3 Technical Reference
The following section contains additional technical information about the EMG features described in this
chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The EMG can work in bridge mode or
routing mode. When the EMG is in routing mode, it supports the following methods.
IP over Ethernet
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an Ethernet
network, without using PPP encapsulation. They are routed between the Ethernet interface and the
WAN interface and then formatted so that they can be understood in a bridged environment. For
instance, it encapsulates routed Ethernet frames into bridged Ethernet cells.
PPP over Ethernet (PPPoE)
Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a
manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how a
personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example RADIUS).
One of the benefits of PPPoE is the ability to let you 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 individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific
configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the EMG (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the EMG does that part of the task. Furthermore, with
NAT, all of the LANs’ computers will have access.

Chapter 6 Broadband
IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one
each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or
static IP. However the encapsulation method assigned influences your choices for IP address and
default gateway.
Introduction to VLANs
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
In Multi-Tenant Unit (MTU) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network
resources of another on the same LAN, thus a user will not see the printers and hard disks of another user
in the same building.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
Introduction to IEEE 802.1Q Tagged VLAN
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a
frame across bridges - they are not confined to the switch on which they were created. The VLANs can
be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a
specific VLAN and provides the information that switches need to process the frame across the network.
A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag
Protocol Identifier), residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag
Control Information), starts after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a
frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to
an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of
4,096 VLANs. Note that user priority and VLAN ID are independent of each other. A frame with VID
(VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and
the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is
used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN
configurations are 4,094.

Multicast
IP packets are transmitted in either one of two ways - Unicast (1 sender - 1 recipient) or Broadcast (1
sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network not everybody and not just 1.
EMG6726/8726-B10A User’s Guide
75
Chapter 6 Broadband
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish membership in a
Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over
version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed
information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of
RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to
239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast
computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of
all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP.
The address 224.0.0.2 is assigned to the multicast routers group.
At start up, the EMG queries all directly connected networks to gather group membership. After that,
the EMG periodically updates this information.
DNS Server Address Assignment
Use Domain Name System (DNS) 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 EMG 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, manually enter them in the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the EMG’s WAN IP address), set
the DNS server fields to get the DNS server address from the ISP.
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an
example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be
written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be
written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
IPv6 Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6
prefix length specifies how many most significant bits (start from the left) in the address compose the
network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.

7.1.2 What You Need to Know
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and
receive information over the airwowaves, wireless networking devices exchange information with one
another. A wireless networking device is just like a radio that lets your computer exchange information
with radios attached to other computers. Like walkie-talkies, most wireless networking devices operate
at radio frequency bands that are open to the public and do not require a license to use. However,
wireless networking is different from that of most traditional radio communications in that there a
number of wireless networking standards available with different methods of data encryption.

7.7 The MESH Screen
Use this screen to enable or disable Zyxel MESH (Multy Pro). It supports AP steering and Band steering. AP
steering allows wireless clients to roam seamlessly between Multy-Pro-supported devices in your MESH
network by using the same SSID and WiFi password. Also, AP steering helps monitor wireless clients and
drop their connections to optimize the EMG bandwidth when the clients are idle or have a low signal.
When a wireless client is dropped, it has the opportunity to steer to a Multy-Pro-supported device with a
strong signal. Band steering allows dual band wireless clients to steer from one band to another.
A MESH network consists of a controller, the EMG, and a maximum of three Multy-Pro-supported
extenders.
When Multy Pro is enabled:
• One Connect will be enabled and grayed out automatically. It’s used for the communication
between the EMG and a Multy-Pro-supported extenders for the setup of a MESH network.
• The SSID and WiFi password of the main 2.4GHz wireless network will be copied to the main 5GHz
wireless network.

7.8 Technical Reference
This section discusses wireless LANs in depth. For more information, see Appendix B on page 286.
7.8.1 Wireless Network Overview
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can connect with numerous
wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and wireless clients, extending
a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or more wireless clients.
The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to one
another in order to exchange information.
The following figure provides an example of a wireless network.
EMG6726/8726-B10A User’s Guide
89
Chapter 7 Wireless
Figure 40 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B use the access
point (AP) to interact with the other devices (such as the printer) or with the Internet. Your EMG is the AP.
Every wireless network must follow these basic guidelines.
• Every device in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentifier.
• If two wireless networks overlap, they should use a different channel.
Like radio stations or television channels, each wireless network uses a specific channel, or frequency,
to send and receive information.
• Every device 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.
Radio Channels
In the radio spectrum, there are certain frequency bands allocated for unlicensed, civilian use. For the
purposes of wireless networking, these bands are divided into numerous channels. This allows a variety of
networks to exist in the same place without interfering with one another. When you create a network,
you must select a channel to use.
Since the available unlicensed spectrum varies from one country to another, the number of available
channels also varies.

7.8.2 Additional Wireless Terms
The following table describes some wireless network terms and acronyms used in the EMG’s Web
Configurator.
Table 22 Additional Wireless Terms
TERM DESCRIPTION
RTS/CTS Threshold In a wireless network which covers a large area, wireless devices are sometimes not
aware of each other’s presence. This may cause them to send information to the AP at
the same time and result in information colliding and not getting through.
By setting this value lower than the default value, the wireless devices must sometimes get
permission to send information to the EMG. The lower the value, the more often the
devices must get permission.
If this value is greater than the fragmentation threshold value (see below), then wireless
devices never have to get permission to send information to the EMG.
Preamble A preamble affects the timing in your wireless network. There are two preamble modes:
long and short. If a device uses a different preamble mode than the EMG does, it cannot
communicate with the EMG.
Authentication The process of verifying whether a wireless device is allowed to use the wireless network.
Fragmentation
Threshold
A small fragmentation threshold is recommended for busy networks, while a larger
threshold provides faster performance if the network is not very busy.
Chapter 7 Wireless
7.8.3 Wireless Security Overview
By their nature, radio communications are simple to intercept. For wireless data networks, this means
that anyone within range of a wireless network without security can not only read the data passing over
the airwaves, but also join the network. Once an unauthorized person has access to the network, he or
she can steal information or introduce malware (malicious software) intended to compromise the
network. For these reasons, a variety of security systems have been developed to ensure that only
authorized people can use a wireless data network, or understand the data carried on it.
WPA2-PSK does two things. First, it authenticates. This means that only people presenting the right
credentials (often a username and password, or a “key” phrase) can access the network. Second, it
encrypts. This means that the information sent over the air is encoded. Only people with the code key
can understand the information, and only people who have been authenticated are given the code
key.
Because of the damage that can be done by a malicious attacker, it’s not just people who have
sensitive information on their network who should use security. Everybody who uses any wireless network
should ensure that effective security is in place.
A good way to come up with effective security keys, passwords and so on is to use obscure information
that you personally will easily remember, and to enter it in a way that appears random and does not
include real words. For example, if your mother owns a 1970 Dodge Challenger and her favorite movie is
Vanishing Point (which you know was made in 1971) you could use “70dodchal71vanpoi” as your
security key.
The following sections introduce different types of wireless security you can set up in the wireless
network.
EMG6726/8726-B10A User’s Guide
91
7.8.3.1 SSID
Normally, the EMG acts like a beacon and regularly broadcasts the SSID in the area. You can hide the
SSID instead, in which case the EMG 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 wireless devices to
get the SSID. In addition, unauthorized wireless devices can still see the information that is sent in the
wireless network.
7.8.3.2 MAC Address Filter
Chapter 7 Wireless
Every device that can use a wireless network has a unique identification number, called a MAC
address.
00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless network,
see the device’s User’s Guide or other documentation.
You can use the MAC address filter to tell the EMG which devices are allowed or not allowed to use the
wireless network. If a device is allowed to use the wireless network, it still has to have the correct
information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does
not matter if it has the correct information.
This type of security does not protect the information that is sent in the wireless network. Furthermore,
there are ways for unauthorized wireless devices to get the MAC address of an authorized device. Then,
they can use that MAC address to use the wireless network.
1
A MAC address is usually written using twelve hexadecimal characters2; for example,
7.8.3.3 User Authentication
Authentication is the process of verifying whether a wireless device is allowed to use the wireless
network. You can make every user log in to the wireless network before using it. For wireless networks,
you can store the user names and passwords for each user in a RADIUS server. This is a server used in
businesses more than in homes. If you do not have a RADIUS server, you cannot set up user names and
passwords for your users.
Unauthorized wireless 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.
7.8.3.4 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.
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.
EMG6726/8726-B10A User’s Guide
92
Chapter 7 Wireless
The types of encryption you can choose depend on the type of authentication. (See Section 7.8.3.3 on
page 92 for information about this.)
Table 23 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION
Weakest No Security
Strongest WPA2-PSK
For example, If users do not log in to the wireless network, you can choose no encryption or WPA2-PSK.
Usually, you should set up the strongest encryption that every device in the wireless network supports. For
example, suppose you have a wireless network with the EMG and you do not have a RADIUS server.
Therefore, there is no authentication.
Note: It is recommended that wireless networks use WPA2-PSK.
Many types of encryption use a key to protect the information in the wireless network. The longer the
key, the stronger the encryption. Every device in the wireless network must have the same key.
7.8.4 Signal Problems
Because wireless networks are radio networks, their signals are subject to limitations of distance,
interference and absorption.
Problems with distance occur when the two radios are too far apart. Problems with interference occur
when other radio waves interrupt the data signal. Interference may come from other radio
transmissions, such as military or air traffic control communications, or from machines that are
coincidental emitters such as electric motors or microwaves. Problems with absorption occur when
physical objects (such as thick walls) are between the two radios, muffling the signal.
7.8.5 BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless
station and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS traffic blocking is disabled,
wireless station A and B can access the wired network and communicate with each other. When IntraBSS traffic blocking is enabled, wireless station A and B can still access the wired network but cannot
communicate with each other.
EMG6726/8726-B10A User’s Guide
93
Figure 41 Basic Service set
Chapter 7 Wireless
7.8.6 MBSSID
Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the
cost of buying extra APs, there is also the possibility of channel interference. The EMG’s MBSSID (Multiple
Basic Service Set IDentifier) function allows you to use one access point to provide several BSSs
simultaneously. You can then assign varying QoS priorities and/or security modes to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
7.8.6.1 Notes on Multiple BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have different BSSIDs (they are in
different BSSs), but have the same keys, they may hear each other’s communications (but not
communicate with each other).
7.8.7 Preamble Type
Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the
synchronization field in a packet.
Short preamble increases performance as less time sending preamble means more time for sending
data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short
preamble.
EMG6726/8726-B10A User’s Guide
94
Chapter 7 Wireless
Use long preamble if you are unsure what preamble mode other wireless devices on the network
support, and to provide more reliable communications in busy wireless networks.
Use short preamble if you are sure all wireless devices on the network support it, and to provide more
efficient communications.
Use the dynamic setting to automatically use short preamble when all wireless devices on the network
support it, otherwise the EMG uses long preamble.
Note: The wireless devices MUST use the same preamble mode in order to communicate.
7.8.8 WiFi Protected Setup (WPS)
Your EMG 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).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) 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.
7.8.8.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled device, and
allowing them to connect automatically. You do not need to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their
configuration utilities instead of or in addition to the physical button.
Take the following steps to set up WPS using the button.
1 Ensure that the two devices you want to set up are within wireless range of one another.
2 Look for a WPS button on each device. If the device does not have one, log into its configuration utility
and locate the button (see the device’s User’s Guide for how to do this - for the EMG, see Section 7.5 on
page 82).
3 Press the button on one of the devices (it doesn’t matter which). For the EMG you must press the WPS
button for more than three seconds.
4 Within two minutes, press the button on the other device. The registrar sends the network name (SSID)
and security key through an secure connection to the enrollee.
If you need to make sure that WPS worked, check the list of associated wireless clients in the AP’s
configuration utility. If you see the wireless client in the list, WPS was successful.
7.8.8.2 How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role. One device acts
as the registrar (the device that supplies network and security settings) and the other device acts as the
EMG6726/8726-B10A User’s Guide
95
Chapter 7 Wireless
enrollee (the device that receives network and security settings. The registrar creates a secure EAP
(Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the WPA2-PSK preshared key to the enrollee. Whether WPA2-PSK is used depends on the standards supported by the
devices. If the registrar is already part of a network, it sends the existing information. If not, it generates
the SSID and WPA2-PSK randomly.
The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a
WPS-enabled access point.

The roles of registrar and enrollee last only as long as the WPS setup process is active (two minutes). The
next time you use WPS, a different device can be the registrar if necessary.
ACTIVATE
WPS
REGISTRARENROLLEE
The WPS connection process is like a handshake; only two devices participate in each WPS transaction.
If you want to add more devices you should repeat the process with one of the existing networked
devices and the new device.
Note that the access point (AP) is not always the registrar, and the wireless client is not always the
enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless clients.
By default, a WPS devices is “unconfigured”. This means that it is not part of an existing network and can
act as either enrollee or registrar (if it supports both functions). If the registrar is unconfigured, the security
settings it transmits to the enrollee are randomly-generated. Once a WPS-enabled device has
connected to another device using WPS, it becomes “configured”. A configured wireless client can still
act as enrollee or registrar in subsequent WPS connections, but a configured access point can no longer
act as enrollee. It will be the registrar in all subsequent WPS connections in which it is involved. If you
want a configured AP to act as an enrollee, you must reset it to its factory defaults.
EMG6726/8726-B10A User’s Guide
96
7.8.8.3 Example WPS Network Setup
This section shows how security settings are distributed in an example WPS setup.
The following figure shows an example network. In step 1, both AP1 and Client 1 are unconfigured.
When WPS is activated on both, they perform the handshake. In this example, AP1 is the registrar, and
Client 1 is the enrollee. The registrar randomly generates the security information to set up the network,
since it is unconfigured and has no existing information.
Figure 43 WPS: Example Network Step 1
CLIENT 1
In step 2, you add another wireless client to the network. You know that Client 1 supports registrar mode,
but it is better to use AP1 for the WPS handshake with the new client since you must connect to the
access point anyway in order to use the network. In this case, AP1 must be the registrar, since it is
configured (it already has security information for the network). AP1 supplies the existing security
information to Client 2.

In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot
use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports
the registrar function, so you use it to perform the WPS handshake instead.

7.8.8.4 Limitations of WPS
WPS has some limitations of which you should be aware.
• WPS works in Infrastructure networks only (where an AP and a wireless client communicate). It does
not work in Ad-Hoc networks (where there is no AP).
• When you use WPS, it works between two devices only. You cannot enroll multiple devices
simultaneously, you must enroll one after the other.
For instance, if you have two enrollees and one registrar you must set up the first enrollee (by pressing
the WPS button on the registrar and the first enrollee, for example), then check that it successfully
enrolled, then set up the second device in the same way.
• WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to a
network you already set up using WPS.
WPS works by automatically issuing a randomly-generated WPA2-PSK pre-shared key from the
registrar device to the enrollee devices. Whether the network uses WPA2-PSK depends on the device.
You can check the configuration interface of the registrar device to discover the key the network is
using (if the device supports this feature). Then, you can enter the key into the non-WPS device and
join the network as normal (the non-WPS device must also support WPA2-PSK).
• When you use the PBC method, there is a short period (from the moment you press the button on one
device to the moment you press the button on the other device) when any WPS-enabled device
could join the network. This is because the registrar has no way of identifying the “correct” enrollee,
and cannot differentiate between your enrollee and a rogue device. This is a possible way for a
hacker to gain access to a network.
You can easily check to see if this has happened. WPS works between only two devices
simultaneously, so if another device has enrolled your device will be unable to enroll, and will not
have access to the network. If this happens, open the access point’s configuration interface and look
at the list of associated clients (usually displayed by MAC address). It does not matter if the access

point is the WPS registrar, the enrollee, or was not involved in the WPS handshake; a rogue device
must still associate with the access point to gain access to the network. Check the MAC addresses of
your wireless clients (usually printed on a label on the bottom of the device). If there is an unknown
MAC address you can remove it or reset the AP.

8.1 Overview
