Restoring the factory settings
Scenario 1
Symptom
When you replace the router, the router password is lost. As a result, you cannot log in to the
router and do not know the router configuration.
Solution
Because the router is replaced, you do not need to save the configuration of the router. In this case,
you can press the RESET button for more than 4 seconds to reboot the router and restore the
factory settings. Then, you can use the username and password shipped with the router to log in to
the router.
When the router configuration must be saved and you have a console cable, you can log in to the
router from the BootWare menu.
Scenario 2
Symptom
After the configuration is modified, the network connectivity is lost. When you check the
configuration, the configuration is very complicated and it is hard to locate the errors. In this case,
you must configure the router again.
