Let me tell you what is happening.....
Not sure if I overlook something but as far as I can see you didn't yet describe what happens. How do you know that it does not work? Are there any error messages? How far do you come? What works, what does not work?
Does Genesis go online? Can you ping yourself? Can you ping the router? Is the DNS "you copied from Windows7" different from the router? If yes, can you ping the DNS?
