1. Look for "link lights" (continuity indicator lamp and activity indicator lamp, if present on the particular brand of nic you have - not all do)

2. Ascertain that you are using a known good patch cord.

3. I have downloaded the diagnostic utility(ies) with the drivers for some 3com cards.

What make and model NIC are you troubleshooting?

How do you know that it is faulty?

4. Check BIOS/setup to ascertain that the nic is turned "ON" if it's the onboard nic that's giving your problems; if it's not the onboard nic that's "faulty" make sure the onboard nic is set to "OFF" so your add/in network interface card is properly detected.

Please provide some more details (motherboard, os, VISA card number, etc.) to allow us to help you diagnose your "faulty network adapter".

Also if you know how to create a loopback cable, it would be the best!

Please pardon me for jumping/into the thread initiated by LIMMC123 to pose my own response to rmarrero's submission.

The idea seems almost too simple for me to be asking this question, but here goes anyway:

Do you know of a link to an article (and would you share with us) that describes how to build one's own loopback? (Something like what MakeItSimple.com has to offer?) My own thought on the matter has been that if I would look at what the 568A and 568B pinouts are, then which wires I have to loopback to my RJ45 plug would be obvious. I just haven't gotten A Round Tuit. If somebody else has done it, then let's read and check their solution. If no one else has done it, then let us draft our own solution and see if'n we can get our hosts here to post our creation for us.

Thanks for entertaining my thought. I apologize for being so lazy that I just haven't yet done such a simple exercise.
