After installing Windows 7 there is no internet

[jejo1]

After Installing Windows 7 ultimate, windows didn't connect to the Internet automatically. So I installed the ethernet driver but it also didn't connect. So what shall I do to get it to work?
PS: My mobo is a GA-H61M-S2P
Sorry for choosing an unsuitable category but I didn't find a suitable one.
