Appendix A Troubleshooting

Q1. What should I do if I forget the username and password for the router's web
management page?
Please restore the router to factory defaults. The default management address of the
router is http://192.168.0.1. The default username and password are both admin. All
current settings will be cleared once the router is restored. If you have a backup of your
configurations, you can import it after the factory restore is complete.

The PWR LED should be lit up when the power system works normally. If the PWR LED

2. Make sure the voltage of the power supply meets the requirement of the input voltage of
the router.
