• 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 EMG3435-Q20A to its factory default settings. If you backed up
an earlier configuration file, you would not have to totally re-configure the EMG3435-Q20A. You could
simply restore your last configuration.
1.5 Re se tting the EMG 3435- Q 20A
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 EMG3435-Q20A to reload the factory-default configuration file.
This means that you will lose all configurations that you had previously saved, the password will be reset
to “1234” and the IP address will be reset to “192.168.1.1”.

3 Press the RESET button for longer than five seconds to set the EMG3435-Q20A back to its factory-default

1.6 The WPS Butto n
Your EMG3435-Q20A 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) 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.
You can use the WPS button on the rear panel of the EMG3435-Q20A to activate WPS in order to quickly
set up a wireless network with strong security.
1 Make sure the power LED is on (not blinking).
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 EMG3435-Q20A.
