Testing NIC Card

[DanielPatrick]

I have a computer and would like to test that the NIC Card is working fine. What are the tests that I can do to it in order to confirm this? For example, I can ping to itself 127.0.0.1 and what else?

Pinging 127.0.0.1 won't test the physical port if there is any damage, it just tests the drivers of the card and the TCP/IP stack in the OS AFAIK. I'd plug it into a known working gig switch with CAT5e or better and make sure you can associate at 1Gbps.
