RESET
button for over four seconds to restore
the factory settings. Then you can use the initial username and password to access the router.
If you are to save the configuration and a console cable is available, you can access the router
from the BootWare menu.

very complicated and it is hard to locate the errors.

RESET
button
for a short time or power off the router.
If you have saved the configuration, delete the configuration file at the CLI or press the
RESET
button to restore the factory settings.
