Ways to Manage the NBG-416N

Use any of the following methods to manage the NBG-416N.

•

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 ZyXEL Device.

•

Web Configurator. This is recommended for everyday management of the NBG-

416N using a (supported) web browser.

1.4

Good Habits for Managing the NBG-416N

Do the following things regularly to make the NBG-416N more secure and to

manage the NBG-416N 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-416N to its factory default settings. If you backed up an earlier

configuration file, you would not have to totally re-configure the NBG-416N. You

could simply restore your last configuration.
