CHAPTER 1
Introduction
1.1 Overview
This chapter introduces the main features and applications of the EMG2881-T20A.
The EMG2881-T20A 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 firewall is also available for secure Internet computing.
1.1.1 Ethernet WAN
If you have another broadband modem or router (such as ADSL) available, you can use the Ethernet
WAN port and then connect it 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
EMG2881-T20A.
Figure 1 EMG2881-T20A’s Internet Access Application: Ethernet WAN
1.1.2 Wireless Access
The EMG2881-T20A 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 EMG2881-T20A to
access network resources and the Internet.
Your EMG2881-T20A 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 Chapter 4 on page 24 for more information about how to set up a wireless network.
Chapter 1 Introduction
EMG2881-T20A User’s Guide

Figure 2 Wireless Access Example
1.2 Applications
You can have the following networks with the EMG2881-T20A:
•Wired. You can connect network devices via the Ethernet ports of the EMG2881-T20A so that they
can communicate with each other and access the Internet.
•Wireless. Wireless clients can connect to the EMG2881-T20A to access network resources. You can use
WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-compatible
device.
•WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the EMG2881-T20A
Use any of the following methods to manage the EMG2881-T20A.
• 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 EMG2881-T20A.
• Web Configurator. This is recommended for everyday management of the EMG2881-T20A using a
(supported) web browser.
1.4 Good Habits for Managing the EMG2881-T20A
Do the following things regularly to make the EMG2881-T20A more secure and to manage the EMG2881-
T20A 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 EMG2881-T20A to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the EMG2881-T20A. You could
simply restore your last configuration.

1.5.4 Rear Panel LEDs (Lights)
The following table describes the rear panel LEDs.
1.5.5 Using the WLAN and WPS Buttons
If the wireless network is turned off, go to the Wireless screen to turn it on. Once the 2.4G WLAN/WPS or
5G WLAN/WPS LED turns white, the wireless network is active.
You can also use the WPS button to quickly set up a secure wireless connection between the EMG2881-
T20A and a WPS-compatible client by adding one device at a time.
To activate WPS:
1Make sure the POWER LED is on and not blinking.
2Press the WPS button for more than one second and release it.
3Press the WPS button on another WPS-enabled device within range of the EMG2881-T20A. The WLAN
2.4G and WLAN 5G LEDs flash amber while the EMG2881-T20A sets up a WPS connection with the other
wireless device.
4Once the connection is successfully made, the WLAN 2.4G and WLAN 5G LEDs shine white.
1.5.6 Resetting the EMG2881-T20A
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 EMG2881-T20A 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 “admin”, the password will be reset to the factory default (see the device label), and the IP address
will be reset to “192.168.1.1” (router mode).
1.5.6.1 How to Use the RESET Button
1Make sure the POWER LED is on.
2Press the RESET button for one to four seconds to restart/reboot the EMG2881-T20A.
