Re: dial-up link for cisco router 1841

It is possible if the IOS on your router supports the necessary dialing features. You'll need to use WIC-1AM analog modem modules (or similar) in each router. A cheaper alternative would be to use standard desktop modems...the serial ports could be connected to the Aux interfaces on the routers.
Good luck...and I hope this is helpful!!

Connect to cisco 1841

This is more of a business unit. It requires a serial port connection and a fair amount of CISCO networking engineering knowledge. It is command only. No GUI interface.

Garbage in Cisco 1841

There are two things that can cause this:
  1. Incorrect serial settings. The default settings are 9600 baud, stop bits of 1, and parity 0. However, it is possible that these settings were changed. Likely, the baud setting may be higher as someone may have tried to XMODEM an IOS image onto the device and wanted faster speeds.
  2. Bad connection, cable
I hope this answers your question.

I forgot to change the default public credential User: cisco and pwd: cisco. Un fortunately I did restart the router. I would like your assistance to gain access to the router or to reset it back to...

Here is a cisco page that goes over the password recovery procedure. Once you reset the credentials, you can make any configuration changes needed. You will also have the option to keep the existing configuration in place but change the password, if the configuration has any use to you.

Cisco 1841 router

You can ID the cards by seeing if the card has "V2" on the metal plate. I believe an 1800 chasis requires a V2 card.
