Hi,<br />
<br />
The Cisco 1841 router is modular so you should be able to replace that card.<br />
Try refresshing the config on your existing card just in case their has been a corruption.<br />
<br />
You will have to upload a config to your new WIC card for it to work as far as I am aware.

I have a CISCO 1841 and think that the T1 WIC is bad. &nbsp;Currently cannot access the internet and my ISP confirm that everything is fine on their end. &nbsp;How can I verify that me T1 WIC on the cisco is bad.<br />
<br />
If I need to replace the WIC, is it just plug and play on the new WIC? &nbsp;Do I need to do any configuration on the cisco to see the new WIC?

How do I test to see if my T1 WIC is bad.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
