I have a CISCO 1841 and think that the T1 WIC is bad.  Currently cannot access the internet and my ISP confirm that everything is fine on their end.  How can I verify that me T1 WIC on the cisco is bad.

If I need to replace the WIC, is it just plug and play on the new WIC?  Do I need to do any configuration on the cisco to see the new WIC?

Hi,

The Cisco 1841 router is modular so you should be able to replace that card.
Try refresshing the config on your existing card just in case their has been a corruption.

You will have to upload a config to your new WIC card for it to work as far as I am aware.
The Wic itself does not have any configuration that you have to worry about. As long as you install the new one in the same slot as the old you will be fine. As for testing the card itself, you will need a loopback cable. They are super easy to make. just cut the end off of a patch cord. Have a look here
