1.3 Good Habits for Managing the ZyXEL Device

Do the following things regularly to make the ZyXEL Device more secure and to manage the
ZyXEL Device 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, or if you forget your password and have to reset the ZyXEL Device to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the ZyXEL Device. You could simply restore your last configuration.
