1.2
Securing the NBG-418N v2
Do the following things regularly to make the NBG-418N v2 more secure and to manage the NBG-
418N v2 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 NBG-418N v2 to its factory default settings. If
you backed up an earlier configuration file, you would not have to totally re-configure the NBG-
418N v2. You could simply restore your last configuration.

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 (recommended) 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.
The
WPS/RESET
single button is located at the back panel of the NBG-418N v2.

Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.
1
Select a position free of obstructions on a wall strong enough to hold the weight of the device.
2
Mark two holes on the wall at the appropriate distance apart for the screws.
Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.
3
If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the
full depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way
in - leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the
screws all the way in - leave a gap of about 0.5 cm.
4
Make sure the screws are fastened well enough to hold the weight of the NBG-418N v2 with the
connection cables.
