1.1 Overview

Eject buttons
USB ports
This chapter introduces the main features and applications of the EMG2926-Q10A.
The EMG2926-Q10A extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. You can set up a wireless network with other IEEE
802.11a/ac/b/g/n compatible devices.
A range of services such as a firewall and content filtering are also available for secure Internet computing. The EMG2926-Q10A also supports the new StreamBoost technology, which is smart Quality of Service (QoS), to redistribute traffic over the EMG2926-Q10A for the best possible performance in a home network.
There are two USB 2.0 ports on the side panel of your EMG2926-Q10A. You can connect USB (version 2.0 or lower) memory sticks, USB hard drives, or USB devices for file sharing. The EMG2926-Q10A automatically detects the USB devices.
CHAPTER 1

Introduction

Two USB eject buttons are located above the USB ports. Push the eject button of the corresponding USB port for 2 seconds. Make sure the USB LED is off before removing your USB device. This will remove your USB device safely, preventing file or data loss if it is being transmitted through the USB device.
Figure 1 USB Ports and Eject Buttons
Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB
storage devices (such as memory sticks, USB hard drives) and/or USB devices. Other USB products are not guaranteed to function properly with the EMG2926­Q10A.

1.1.1 Dual-Band
The EMG2926-Q10A is a dual-band AP and able to function 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.
Figure 2 Dual-Band Application
Chapter 1 Introduction

1.2 Applications

You can have the following networks with the EMG2926-Q10A:
• Wired. You can connect network devices via the Ethernet ports of the EMG2926-Q10A so that they can communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the EMG2926-Q10A to access network resources. You can use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS­compatible device.
• WAN. Connect to a broadband modem/router for Internet access.

1.3 Ways to Manage the EMG2926-Q10A

Use any of the following methods to manage the EMG2926-Q10A.
• WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your EMG2926-Q10A.
• Web Configurator. This is recommended for everyday management of the EMG2926-Q10A using a (supported) web browser.

Chapter 1 Introduction

1.4 Good Habits for Managing the EMG2926-Q10A

Do the following things regularly to make the EMG2926-Q10A more secure and to manage the EMG2926-Q10A 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 EMG2926-Q10A to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the EMG2926-Q10A. You could simply restore your last configuration.

1.5 Resetting the EMG2926-Q10A

If you forget your password or IP address, or you cannot access the Web Configurator, you will need to use the RESET button at the back of the EMG2926-Q10A to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the user name will be reset to “supervisor” or “admin”, the password will be reset to “supervisor” or “1234”, and the IP address will be reset to “192.168.1.1” (router mode).
1.5.1 How to Use the RESET Button
1 Make sure the power LED is on.
2 Press the RESET button for one to four seconds to restart/reboot the EMG2926-Q10A.
3 Press the RESET button for longer than five seconds to set the EMG2926-Q10A back to its factory-
default configurations.

1.6 The WPS Button

Your EMG2926-Q10A supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.
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) on 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.

2 Press the WPS button for more than three seconds and release it. Press the WPS button on another
WPS-enabled device within range of the EMG2926-Q10A.
Note: You must activate WPS on the EMG2926-Q10A and on another wireless device

1.7 LEDs

Look at the LED lights on the front panel to determine the status of the EMG2926-Q10A. Use the LED button at the side panel of the device to turn the LED lights on or off. If you have already pushed the LED button to the ON position but none of the LEDS are on, make sure the EMG2926­Q10A is receiving power and the power is turned on.

6.1 Overview

This chapter provides tutorials for setting up your EMG2926-Q10A.
• Set Up a Wireless Network Using WPS
• Connect to EMG2926-Q10A Wireless Network without WPS
• Using Multiple SSIDs on the EMG2926-Q10A

6.2 Set Up a Wireless Network Using WPS

This section gives you an example of how to set up wireless network using WPS. This example uses the EMG2926-Q10A as the AP and NWD210N 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 via the web configurator or utility. 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 37. 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 EMG2926-Q10A’s interface. See Section 6.2.2 on page
38. 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 EMG2926-Q10A is turned on. Make sure the WIFI button (at the back panel of
the EMG2926-Q10A) is pushed in, and that the device is placed within range of your notebook.
2 Make sure that you have installed the wireless client (this example uses the NWD210N) driver and
utility in your notebook.
3 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or
WPS button)
4 Log into EMG2926-Q10A’s Web Configurator and press the Push Button in the Configuration >
Network > Wireless LAN 2.4G > WPS Station screen.

Note: It doesn’t matter which button is pressed first. You must press the second button
within two minutes of pressing the first one.
The EMG2926-Q10A sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the EMG2926-Q10A securely.
The following figure shows you an example to set up wireless network and security by pressing a button on both EMG2926-Q10A and wireless client (the NWD210N in this example).
Figure 18 Example WPS Process: PBC Method
6.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both EMG2926-Q10A’s configuration interface and the client’s utilities.
1 Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method
to get a PIN number.

6.4 Using Multiple SSIDs on the EMG2926-Q10A

You can configure more than one SSID on a EMG2926-Q10A. See Section 9.4 on page 79.
This allows you to configure multiple independent wireless networks on the EMG2926-Q10A 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 EMG2926-Q10A 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 EMG2926-Q10A (such as a printer).

8.1 Overview

This chapter discusses the EMG2926-Q10A’s WAN screens. Use these screens to configure your EMG2926-Q10A 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.

8.2 What You Can Do

•Use the Internet Connection screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 8.4 on page 57).
•Use the Advanced screen to enable multicasting, configure Windows networking and bridge
(Section 8.5 on page 64).

8.3 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 EMG2926-Q10A.

Chapter 8 WAN
8.3.1 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 EMG2926-Q10A, which makes it accessible from an outside network. It is used by the EMG2926-Q10A to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the EMG2926-Q10A 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 EMG2926-Q10A 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 EMG2926-Q10A’s WAN
IP address), set the DNS server fields to get the DNS server address from the ISP.
WAN MAC Address
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 - IP 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.
EMG2926-Q10A User’s Guide

Page 57
Chapter 8 WAN
Multicast
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 26 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 EMG2926-Q10A supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the EMG2926-Q10A queries all directly connected networks to gather group membership. After that, the EMG2926-Q10A periodically updates this information. IP multicasting can be enabled/disabled on the EMG2926-Q10A WAN interface in the Web Configurator (WAN). Select None to disable IP multicasting on these interfaces.

8.4.2 PPPoE Encapsulation
The EMG2926-Q10A 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.
Chapter 8 WAN
By implementing PPPoE directly on the EMG2926-Q10A (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the EMG2926-Q10A does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

CHAPTER 9

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 EMG2926-Q10A is the AP.

•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 9.10
on page 87).
Chapter 9 Wireless LAN
9.1.2 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.
EMG2926-Q10A User’s Guide

Page 68
MAC Address Filter
Chapter 9 Wireless LAN
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters 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.
2
; for example, 00A0C5000002 or
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.
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.
EMG2926-Q10A User’s Guide
68
Page 69
Chapter 9 Wireless LAN
The types of encryption you can choose depend on the type of user authentication. (See page 68 for information about this.)
Table 17 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.
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 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.
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 or WPA2-PSK in your EMG2926-Q10A, you can also select an option (WPA/WPA-PSK Compatible) to support WPA/WPA-PSK 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/WPA-PSK Compatible option in the EMG2926-Q10A.
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.
Guest WLAN
Guest WLAN allows you to set up a wireless network where users can access to Internet via the EMG2926-Q10A (Z), but not other networks connected to the Z. In the following figure, a guest user can access the Internet from the guest wireless network A via Z but not the home or company network N.
Note: The home or company network N and Guest WLAN network are independent
networks.

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

This displays the channel the EMG2926-Q10A is currently using.
A standard 20 MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps (5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to 300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers speeds of up to 1.3Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select Auto 20/40 MHz or Auto 20/40/80 MHz to allow the EMG2926-Q10A to adjust the channel bandwidth automatically.
40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal.
Select 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding.

11.1 Overview

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the EMG2926-Q10A’s LAN as a DHCP server or disable it. When configured as a server, the EMG2926-Q10A 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.
11.1.1 What You Can Do
•Use the General screen to enable the DHCP server (Section 11.2 on page 93).
•Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 11.3 on page 94).
•Use the Client List screen to view the current DHCP client information (Section 11.4 on page

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network.
The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example).
You assign the LAN IP addresses to the devices (A to D) connected to your EMG2926-Q10A. The ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D going out to the Internet use the IP address of the EMG2926-Q10A, which is 192.168.1.1.

Figure 55 NAT Example
This chapter discusses how to configure NAT on the EMG2926-Q10A.
Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from
the WAN to be forwarded through the EMG2926-Q10A.
12.1.1 What You Can Do
•Use the General screen to enable NAT (Section 12.2 on page 100).

•Use the Port Forwarding screen to set a default server and change your EMG2926-Q10A’s port
forwarding settings to forward incoming service requests to the server(s) on your local network (Section 12.3 on page 101).
•Use the Port Trigger screen to change your EMG2926-Q10A’s trigger port settings (Section
12.5.3 on page 106).
12.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Inside/Outside
This denotes where a host is located relative to the EMG2926-Q10A, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/Local
This denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side.
Chapter 12 NAT
Note: Inside/outside refers to the location of a host, while global/local refers to the IP
address of a host used in a packet.
An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information.
Table 37 NAT Definitions
ITEM DESCRIPTION
Inside This refers to the host on the LAN. Outside This refers to the host on the WAN. Local This refers to the packet address (source or destination) as the packet travels on the LAN. Global This refers to the packet address (source or destination) as the packet travels on the WAN.
Note: NAT never changes the IP address (either local or global) of an outside host.
What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local

network and make them accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall protection. With no servers defined, your EMG2926-Q10A filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address in each packet and then forwards it to the Internet. The EMG2926-Q10A keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this.
