• 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 EMG1302-R10A to its factory default settings. If
you backed up an earlier configuration file, you would not have to totally re-configure the
EMG1302-R10A. You could simply restore your last configuration.

Figure 2 Front Panel
Your EMG1302-R10A 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) 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 6.2 on page 43.

4.4 DHCP Table
Dynamic Host Configuration Protocol (DHCP), RFC 2131 and RFC 2132 allow individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the EMG1302-R10A’s LAN
as a DHCP server or disable it. When configured as a server, the EMG1302-R10A provides the
TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP
server on that network, or else the computer must be manually configured.
Click the DHCP Table (Details...) hyperlink in the Status screen or Monitor > DHCP Table.
Read-only information here relates to your DHCP status. The DHCP table shows current DHCP client
information (including Host Name, IP Address, and Mac Address) of all network clients using
the EMG1302-R10A’s DHCP server.

6.1 Overview
This chapter provides tutorials for setting up your EMG1302-R10A.
• Set Up a Wireless Network with WPS
• Configure Wireless Security without WPS
• Using Multiple SSIDs on the EMG1302-R10A
6.2 Set Up a Wireless Network with WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the EMG1302-R10A as the AP and as the wireless client which connects to a notebook.
Tutorials
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter
or PCI card).
There are two WPS methods for creating a secure connection. This tutorial shows you how to do
both.
• Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 6.2.1 on page 43.This is the easier method.
• PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN
(Personal Identification Number) in the EMG1302-R10A’s interface. See Section 6.2.2 on page
44. This is the more secure method, since one device can authenticate the other.
6.2.1 Push Button Configuration (PBC)
1 Make sure that your EMG1302-R10A is turned on. Make sure the device is placed within range of
your computer.
2 Make sure that you have installed the wireless client (this example uses the ) driver and utility in
your notebook.

6.4 Using Multiple SSIDs on the EMG1302-R10A
Chapter 6 Tutorials
You can configure more than one SSID on a EMG1302-R10A when it is operating in access point or
universal repeater mode. This allows you to configure multiple independent wireless networks on
the EMG1302-R10A as if there were multiple APs (virtual APs). Each virtual AP has its own SSID,
wireless security type and MAC filtering settings. That is, each SSID on the EMG1302-R10A
represents a different access point/wireless network to wireless clients in the network.
Clients can associate only with the SSIDs for which they have the correct security settings. Clients
using different SSIDs can access the Internet and the wired network behind the EMG1302-R10A
(such as a printer). You can allow communication between wireless clients of different SSIDs in the
Configuration > Network > Wireless LAN > General screen. See Section 8.4 on page 78 for

WAN
This chapter discusses the EMG1302-R10A’s WAN screens. Use these screens to configure your
EMG1302-R10A for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other locations.

Chapter 7 WAN
7.3 What You Need To Know
The information in this section can help you configure the screens for your WAN connection, as well
as enable/disable some advanced features of your EMG1302-R10A.
7.3.1 Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username
and password (and service name) for user authentication.
WAN IP Address
The WAN IP address is an IP address for the EMG1302-R10A, which makes it accessible from an
outside network. It is used by the EMG1302-R10A to communicate with other devices in other
networks. It can be static (fixed) or dynamically assigned by the ISP each time the EMG1302-R10A
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) (and a gateway IP address if you use the Ethernet or ENET ENCAP
encapsulation method).
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 EMG1302-R10A 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 EMG1302-R10A’s WAN
IP address), set the DNS server fields to get the DNS server address from the ISP.

Server
The MAC address screen allows users to configure the WAN port's MAC address by either using the
factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default
to select the factory assigned default MAC Address.
Otherwise, click Clone the computer's MAC address and enter the IP address of the computer on
the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to
configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN
Port.
Maximum Transmission Unit
A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eightbit bytes) that can be sent in a packet- or frame-based network. The Transmission Control Protocol
(TCP) uses the MTU to determine the maximum size of each packet in any transmission. Too large
an MTU size may mean retransmissions if the packet encounters a router that can't handle that
large a packet. Too small an MTU size means relatively more header overhead and more
acknowledgements that have to be sent and handled.
7.3.2 Multicast
Chapter 7 WAN
Traditionally, IP packets are transmitted in one of either 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.
Figure 25 Multicast Example
In the multicast example above, systems A and D comprise one multicast group. In multicasting,
the server only needs to send one data stream and this is delivered to systems A and D.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership
in a multicast group - it is not used to carry user data. The EMG1302-R10A supports both IGMP
version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the EMG1302-R10A queries all directly connected networks to gather group
EMG1302-R10A User’s Guide
membership. After that, the EMG1302-R10A periodically updates this information. IP multicasting
can be enabled/disabled on the EMG1302-R10A LAN and/or WAN interfaces in the Web Configurator
(LAN; WAN). Select None to disable IP multicasting on these interfaces.

Auto-IP-Change
When the EMG1302-R10A gets a WAN IP address which is in the same subnet as the LAN IP
address 192.168.1.1, Auto-IP-Change allows the EMG1302-R10A to change its LAN IP address to
10.0.0.1 automatically. If the EMG1302-R10A’s original LAN IP address is 10.0.0.1 and the WAN IP
address is in the same subnet, such as 10.0.0.3, the EMG1302-R10A switches to use 192.168.1.1
as its LAN IP address.
Figure 26 Auto-IP-Change
Auto-IP-Change only works under the following conditions:
• The EMG1302-R10A must be in Router Mode (see Chapter 21 on page 158 for more
information) for Auto-IP-Change to become active.
• The EMG1302-R10A is set to receive a dynamic WAN IP address using the Ethernet or PPPoE
connection type.

7.4.1.1 PPPoE Encapsulation
The EMG1302-R10A supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem
(DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection
using PPPoE.
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 EMG1302-R10A (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the EMG1302-R10A does that
part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

8.1 Overview
This chapter discusses how to configure the wireless network settings in your EMG1302-R10A. See
the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 35 Example of a Wireless Network
CHAPTER 8
Wireless LAN
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 EMG1302-R10A is the AP.
8.2 What You Can Do
•Use the General screen to enter the SSID, select the channel, and configure wireless security
(Section 8.4 on page 78).
•Use the More AP screen to enable and configure multiple wireless networks (Section 8.6 on page
83)
•Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the EMG1302-R10A (Section 8.7 on page 85).
•Use the Advanced screen to allow intra-BSS network and set the RTS/CTS Threshold (Section
8.8 on page 86).
EMG1302-R10A User’s Guide 75
Chapter 8 Wireless LAN
•Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 8.9 on
page 87).
•Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 8.10 on page 88).
•Use the WPS Station screen to add a wireless station using WPS (Section 8.11 on page 89).
•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 8.12
on page 90).
•Use the WDS screen to set up Wireless Distribution System (WDS) (Section 8.13 on page 91).
8.3 What You Should Know
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.
• 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.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
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.
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 characters
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.

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.
User Authentication
You can make every user log in to the wireless network before they can use it. This is called user
authentication.
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.
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 page 77
for information about this.)
Table 19 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest 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.
EMG1302-R10A User’s Guide
77
Chapter 8 Wireless LAN
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.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. IEEE 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.
Note: 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-PSK in your EMG1302-R10A, 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 (depending on the type of wireless network login)
and select the WPA Compatible option in the EMG1302-R10A.
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.
WPS
WiFi Protected Setup (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. Depending on the devices in your network, you can either press a
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification
Number) in the devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the Section 6.2 on page 43.
8.4 General Wireless LAN Screen

Chapter 9 LAN
9.3 What You Need To Know
The actual physical connection determines whether the EMG1302-R10A ports are LAN or WAN
ports. There are two separate IP networks, one inside the LAN network and the other outside the
WAN network as shown next.
Figure 49 LAN and WAN IP Addresses
The LAN parameters of the EMG1302-R10A are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded Web Configurator help regarding what fields need to be
configured.
9.3.1 IP Pool Setup
The EMG1302-R10A is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the EMG1302-R10A itself) in
the lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for
mail, T, web, etc., that you may have.
9.3.2 LAN TCP/IP

10.1 Overview
Dynamic Host Configuration Protocol (DHCP), RFC 2131 and RFC 2132 allow individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the EMG1302-R10A’s LAN
as a DHCP server or disable it. When configured as a server, the EMG1302-R10A provides the TCP/
IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
your LAN, or else the computer must be manually configured.
10.2 What You Can Do
•Use the General screen to enable the DHCP server (Section 10.4 on page 98).
•Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 10.5 on page 99).
•Use the Client List screen to view DHCP client list (Section 10.6 on page 100).

assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. Find out the MAC addresses of your network devices if you intend to add them
to the DHCP Client List screen.

LABEL DESCRIPTION
Enable DHCP Server Select the checkbox to enable DHCP for LAN.
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients (computers) to obtain TCP/IP configuration at startup from a server. Leave the
Enable DHCP Server check box selected unless your ISP instructs you to do
otherwise. Clear it to disable the EMG1302-R10A acting as a DHCP server. When
configured as a server, the EMG1302-R10A provides TCP/IP configuration for the
clients. If not, DHCP service is disabled and you must have another DHCP server on
your LAN, or else the computers must be manually configured. When set as a server, fill
in the following four fields.

The EMG1302-R10A passes a DNS (Domain Name System) server IP address (in the
order you specify here) to the DHCP clients. The EMG1302-R10A only passes this
information to the LAN DHCP clients when you select the Enable DHCP Server check
box. When you clear the Enable DHCP Server check box, DHCP service is disabled
and you must have another DHCP sever on your LAN, or else the computers must have
their DNS server addresses manually configured.

Cancel Click Cancel to begin configuring this screen afresh.
Select From ISP if your ISP dynamically assigns DNS server information (and the
EMG1302-R10A's WAN IP address). The field to the right displays the (read-only) DNS
server IP address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field to the right. If you chose User-Defined, but leave the
IP address set to 0.0.0.0, User-Defined changes to None after you click Apply. If you
set a second choice to User-Defined, and enter the same IP address, the second
User-Defined changes to None after you click Apply.
Select DNS Relay to have the EMG1302-R10A act as a DNS proxy. The EMG1302R10A's LAN IP address displays in the field to the right (read-only). The EMG1302-R10A
tells the DHCP clients on the LAN that the EMG1302-R10A itself is the DNS server.
When a computer on the LAN sends a DNS query to the EMG1302-R10A, the EMG1302R10A forwards the query to the EMG1302-R10A's system DNS server (configured in the
WAN > Internet Connection screen) and relays the response back to the computer.
You can only select DNS Relay for one of the three servers; if you select DNS Relay
for a second or third DNS server, that choice changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
