when i compare it to one from a working 1841 (I have 2 of them), it seems this one is corrupt.

Here is cookie from the working 1841:

Re: cisco 1841 router, corrupt cookie (i think)

Hello,

The following link contains a few hints how to possibly repair a damaged cookie. Note that all information there is completely unwarranted and may well result in frying your router for good. Nevertheless, as it is currently unusable anyway, you may give it a try.

If you need more information please contact me by my email. You can find it in my profile.

Best regards,

i've tried it also by leaving the first line of the cookie intact and replacing the rest with the working one, that doesn't work either, it gets stuck in the same place.

I have been having the same issue on my 1841 here at home, I was wondering if you were able to resolve this yet? I'm at the point where I need to fix the cookie too.

No sorry, I have not been able to fix it yet, i'm still trying though. I'm hoping someone on this forum will come to our rescue. =)

Re: cisco 1841 router, corrupt cookie (i think)

Can you re-post a link to your working cookie? I might be able to get mine working with a proper template. I have my mac address saved from old logs and a few other items.

Re: cisco 1841 router, corrupt cookie (i think)

I have left the router at home so i won't be able to post it till tomorrow or later.

Re: cisco 1841 router, corrupt cookie (i think)

Which part of it is the MAC address anyway?
