An automated troubleshooter is a tool that can find and automatically fix some problems with your computer.
These troubleshooters aren't designed to fix every problem, but they're a useful tool to try because they can often save you time and effort.
Different Windows operating systems use troubleshooters in different ways. Windows 7 uses troubleshooters from within the Windows 7 Action Center. Windows Vista and Windows XP use troubleshooters that can be downloaded from the Microsoft Download Center and then run on your computer. To use an automated troubleshooter, click the link for the troubleshooter for your Windows operating system.
Run the Network troubleshooter first and then test your Internet connection.

in the notification area of your taskbar, and then click Troubleshoot problems
You can also run specific troubleshooters to focus on a particular network or connectivity problem. For example, if you are unable to connect to the Internet or access a particular website, there might be a problem with your Internet connection. Try using the Internet Connections troubleshooter to fix the problem. Follow the steps below.
If you can't connect to a computer on your home network, or on a corporate network, there might be a problem with your computer's network adapter.
