Dell Inspiron N411z :: Hard Drive Replaced But Now Have No Internet Connection

I got my hard drive replaced yeterday but now I have no internet connection, it is a dell inspiron n411z. I have the drivers and utilities cd and have tried installing all of the drivers on it, some have checkmarks and some dont so i am confused. What do I do if i installed them in the wrong order? My internet is still not working and there is a yellow box with an exclamation point by the following items: ethernet controller, network controller, pci simple communications controller, sm bus controller, universal serial bus controller, and unknown device. I had this problem last time the hard drive was replaced and somehow fixed it using this CD but I cant remember how.
