Network and Sharing Center provides real-time status information about your network. You can see if your computer is connected to your network or the Internet, the type of connection, and what level of access you have to other computers and devices on the network. This information can be useful when you set up your network or if you have connection problems. You can find more detailed information about your network in the network map, which is accessible from Network and Sharing Center.
Open Network and Sharing Center by clicking the Start button , clicking Control Panel, clicking Network and Internet, and then clicking Network and Sharing Center.
