1.6 Good Habits for Managing the NBG420N
Do the following things regularly to make the NBG420N more secure and to manage the
NBG420N 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 NBG420N to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the NBG420N. You could simply restore your last configuration.
