Just got a router and I am unable to login, I attempted the password recovery steps (http://www.cisco.com/en/US/products/hw/routers/ps221/products_password_recovery09186a0080094773.shtml)
but Ctrl-Break does not take my to RMON mode. Any idea? It's C1811
When are you issuing the Control+Break, and what terminal software are you using? The Control+Break needs to be issued right after you reload the router, when the initial ROMMON version shows up. Most routers run with "ignore break" set, so trying to break in when the router is running is impossible.
Modern versions of Hyperterm should use Control+Break. Make sure you're hitting that combination at the right time. Pull the power cable, and re-insert it. As soo as you see the initial banner, quickly hit Control+Break, and you should be at the rommon> prompt.
If you need live assistance you can contact the TAC using one of the methods at http://www.cisco.com/en/US/partner/support/tsd_cisco_worldwide_contacts.html .
For some reason, this is not working.
Is there any way to wipe the config without going to RMON mode? Is there no reset button inside the enclosure?
I guess the C1811's password recovery is a bit different than other routers.
I tried: Ctrl C, Ctrl B, Fn Pause, Ctrl Pause, Ctrl-Fn-Pause
Note I am using a laptop
No, you must be able to break into ROMMON to reset the config register so that NVRAM is ignored (thus allowing you to boot on a factory default config). Have you confirmed the serial cable is good? After the router boots, can you type into the console, and get feedback from the router? Perhaps some pins on the cable are damaged, and while you can see the console output, you cannot send data.
Can you post the console output of the router's boot sequence?
Do you have access to the normal boot? I guess not or you wont be doing password recovery. Have you tried to plug maybe an external keyboard.
Another idea: download teraterm ( from http://www.ayera.com/teraterm)
Teraterm is an very good terminal emulation software with very small footprint. In the later version teraterm has a command menu with a 'send break' entry. Try that.
Don't hesitate to type it many many times.
What i do usually is that I power cycle the box and right away start typing the combination.
Hyperterminal should work.
You can also try putty, with the Serial connection check box.

I could never get the fn+Break to work from my laptop. You will have to use a regular keyboard. Can you get consoled in with a desktop or connect a external keyboard to your laptop.
