The following figure shows the LEDs (lights) on the WiMAX Device.
1.3 Good Habits for Device Management
Do the following things regularly to make the WiMAX Device more secure and to
manage the WiMAX 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 WiMAX Device
becomes unstable or even crashes. If you forget your password, you will have to
reset the WiMAX Device to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the WiMAX
Device. You could simply restore your last configuration.
