Hello.. Can anyone help me my ethernet controller driver because I can't use internet.
Yes I can help you. The easiest way to reinstall you Broadcom is -->
Go to Start
click --> Search
write --> Broadcom
click --> All files and documents
click --> This computer
When the search is done you'll see a map something like Programmfile with Broadcom in it. Click on and look for "SETUP.EXE"
Click on setup.exe and then accept.
After this is done you have internet on your computer.
Good luck with it.
(sorry when i wrote some words wrong. I'm not perfect in english.)
