2801 router error

I was in ROM mode on my router, trying to perform a password reset on my router, and now it only shows jibberish to the console when I boot the router. e.g.

I have tried changing the Baud of my console session, because I suspected that I had messed up the console settings in ROM. So far I haven't been able to get any console output other than what is shown above. I thought that ROM would be protected from corruption considering it is 'read only'. What else can I try to regain control of my router? I have another memory card in another 2801, (slightly newer 2801), but I don't want to risk messing up another router.

also, during this, the Sys Power light flashes constantly, but the sys activity light does not flash at all.

Please help if you have any ideas.

Thanks!

Ryan

2801 router error

Ryan,

This looks like you somehow mangled the configuration register value. Have you tried every supported speed between 1200bps and 115200bps, inclusive? Don't forget to hit Enter a few times after each change of the speed of your COM port - do not expect the router to display a correct prompt by itself.

If the only thing you did in the ROMMON was the confreg command then I believe nothing serious happened.

Best regards,

Peter
