yes, I have tried the DELL's diagnostics util. It showed "pass" every time. But I suppose that it only checks the integirty of the EEPROM of the NIC. (correct me if I am wrong). My guess is that maybe the NIC's Tx part has problem, which causes other devices fail to sense and negotiate a mode (10M-half, 10M-full,100M-half, 100M-full etc), though the NIC itself can "see" the otherside of the cable. Do you think this is a possible reason?
By the way, I have restored the machine to a fresh state (not windows restore, but the symantec one). So it seems unlikely a software configuration problem.
I agree that it is not likely a software problem, but does sound like a hard problem with the NIC. One last thing to test. See if you can connect directly to something other than the router. If you can't, and If you are still under warranty you should call tech support and ask for replacement computer or replacement motherboard since the NIC is integrated on the motherboard.

I just "talked" to DELL via online chat. They asked me to do some simple checks which I have done several times. The only thing that is new to me is to use Broadcom's our test tool to perform a check. The test passed. But the problem is still there...... They insisted that it is a software problem. But my Hub and router both fail to recognize it. I have three CAT 5 cables with me, all work well with other machines. I will try to have a professional to do a final test and if it confirms a hardware problem, I will ask DELL to replace a computer since this defect came with the original computer.

The hub is not detecting a connection. Are you absolutely sure that you are using the correct cable and that there are no problems with the cable?

yes. I unplug the cable from the laptop and connect it to another machine, it works......
I'm sure the hub and the cable are both good.

Have you tried running the diagnostics on the network adapter?
