• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the NBG7815 becomes unstable or even crashes. If you forget your
password, you will have to reset the NBG7815 to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the NBG7815. You could simply
restore your last configuration.
1.8 Resetting the NBG7815
If you forget your password or IP address, or you cannot access the Web Configurator, insert a thin
object into the
Reset hole on the NBG7815 to reload the factory-default configuration file. This means
that you will lose all settings that you had previously saved.

Insert a thin object into the Reset hole for longer than 8 seconds to reset the NBG7815 back to its factory-
default configuration (for example, default Standard (Router) operation mode and login IP address of
192.168.123.1, WiFi SSID and password).

1.9 WPS Button
Your NBG7815 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure WiFi
network.
WPS allows you to quickly set up a WiFi 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.
