Well, your output for some N/W commands show that you have three Ethernet controllers. What do you mean by "one of them stopped working" - I mean, which is not working?

What does ifconfig -a say? In my case, it is:
Code:

In this, I have eth0 active. You can see that 347 KB have been transferred. You can try giving <sudo network-admin> and configuring the connection again. Then restart the PC again. Post if you still have probs. Also, please use the CODE tags to display any code. Otherwise, it is very confusing and also looks ugly.

It may be a problem with your NIC (for eth1). Re-configure eth1 and then activate it. Restart the comp and try. It should work, if it does not, then it is a problem with the card. Also try it on any other computer, just to make sure that the card is alright.
