Hi,
There is a round hole on the left side usually that is behind 3 switches. Stick a paper clip and press the button. This brings the router up in monitor mode. In monitor mode, type "bt a:/primary/boot.68k test". If your boot.68k is not in primary directory, then you would need to use a:/boot.68k or whatever location that it is in. This brings up the router without the original configurations. You can then login as root and no password. Once in the router you can type df to display the files, then type rf a:/primary/system and reboot the router. You then will be able to log in as root with no passwords with your ip, path, and port settings still the same.
