Problem with xbox live network

I have a large concern and even after having consulted all the forums existing, impossible to find an answer which functions at home. I have a xbox 360 that I wish to connect to my acer portable equipped with Windows Vista.This last is connected to Internet via wifi with my livebox.

Thanks to a Ethernet cable, I connect it to my xbox.

During one moment, this connection functioned, but since I started again my ADSL, impossible to connect itself to the live one. The console indicates to me that there is a problem of address IP. The concern is that I know absolutely nothing there addresses IP of it…

My PC has two charts network, a wifi and Ethernet. In the manager of network of Vista, I see that the chart wifi is well connected to Internet however, the other chart network is connected to a “network not identified”

The xbox does not find address IP of my ADSL?

How to find the good IP addresses, waiter DNS, footbridge by defect… etc ?

How to make so that my PC recognizes the console instead of a “network not identified”?

Please help me, I begin with Peter a cable…
Thank you in advance

You want to do what exactly?

Why connect Xbox to the PC?

yes here, to benefit from connection Internet of my PC on the xbox

Why you do not connect it directly to your Livebox?

livebox is too much far from the xbox quite simply

ok on your PC make the following thing so that your config network is seen:

You support and you maintenances the Windows key and you press on the key R, you slackenings all === in the dialogue box which opened you slaps cmd /k ipconfig /all > ip.txt && notepad ip.txt then click on OK
