Network problem

[badapples]

Hi,

I have a Thinkpad T61p. All works well with the default XP image but very slow. I want to install Vista 64 bits. All went smooth except the fact that right now I have a problem with the network (ethernet). I have installed the driver from the Lenovo site. I don't know exactly how to track down such a problem.
If someone knows a solution or has encountered this type of problem, please let me know.

Thank you
