with them I connect with an Ethernet Cable
To what?

none of those commands worked except for the "netcardconfig".
This is strange. What is the output/error messages?

In which case it told me that no network cards were detected
this happens when you click YES on the dialog which ask "Use DCHP Broadcast" and your netcard IP address are not set up properly assuming you have as netcard installed.

To get the IP's use your windows box. At the commnad prompt type: ipconfig
then go back to your Linux box and do the netcardconfig thing, this time choose NO at the dialog and enter the the IP's from your windows box when prompted.
