@majidbindaban If password recovery is disabled on your IR1101, you won't be able to access ROMMON using the break sequence or reset button. The Cisco document confirms that without enabling password recovery beforehand, there's no direct way to reset the password via ROMMON.
Since you don’t know the IP or credentials, Telnet/SSH won’t help unless you have access to an active session (like an open console or saved credentials elsewhere). Your best option is to factory reset the router by booting from an external image (if supported) or replacing the device if it's completely locked out.
If the router is still accessible via the console but you can't log in, you might try checking for AAA authentication fallback options (like local authentication failing over to a remote server). Otherwise, a full reset might be the only solution.
