problems with setting first username and password

hawaiiangods · ‎01-10-2015

I haven't used a cisco router in over 12 years, so I'm a bit rusty. I had to replace a nortel box for a small charter school here in Hawaii, so I decided to go with a cisco 1941 / K9 router. using a usb terminal connection I started up the router as directed in the PDF documentation for this box. It warned me that I must change the starting username and password (<cisco> and <cisco> respectively) with my own username and password. I wanted to change this to <cisco1> and a simple password. I thought I followed the directions, but I failed to reset the user name and password. As I was looking up online for help on how to set a new username and password, the terminal window timed-out and now I can't log in to the 1941 router at all.

How do I reset the router? Once I do how do I correctly setup username and password after I login once with cisco and cisco?

Any help would be appreciated.

I'm attaching a screen capture of the terminal window...

How do I reset the router?

Power OFF the router.
If you look at the back (where the power button is) and to the lower left-hand corner, you'll observe two CF slots. Pop the cover open and eject the CF.
Power up the router.
Observe the console terminal and when you see "rommon1>" enter the command "confreg 2142".
After the command has been accepted, insert the CF back and reboot the router.
Your router should boot into factory default (Username & Password are "cisco") but the config-registry value is still 2102.
Do the following:

conf t
config-registry 0x2102
username BLAH password BLAH
end

Aloha from Hawaii,

Thank you for the quick response. I'm setting up a new campus, so it took me a while to get back to my 1941/K9 problem. I followed the directions that you prescribed, but I ran into something different when I rebooted the router (after your step 5). Instead of getting a prompt where I could type in:

conf t

config-registry 0x2102

etc.

I got the following:

Would you like to enter the initial configuration dialog? [yes/no]:

If I answer no, I get a router> prompt that will not accept the conf t

If I answer yes and proceed with the setup, I'm prompted to enter the initial configuration dialog every time I telnet in...

Any advice you can offer?

Would you like to enter the initial configuration dialog? [yes/no]:

Sorry for the late response, I was down-and-out with flu.

So, when you are greeted with this message, enter the option "no" and you'll be be in factory default where the prompt is going to be "Router>". Go into enable mode using the command "enable" (the prompt will now be "Router#" and then continue with Step 7 above.
