If the status of the Local Area Connection says "Unplugged," tighten the network cable attached at the back of the computer. If the network cable is properly connected and the status does not change, check your modem and router (if in use) if they are properly plugged in and turned on. If you are using a router, plug the network cable into a different port if there are other slots available. If this still does not work, replace your network cable with a new one.

If the status of your Local Area Connection says "Limited or No Connectivity," this means that the computer is connected properly to the computer, but the router (if in use) may be misconfigured. Right-click on the connection and click "Repair." If this step does not work, unplug your modem and wait one minute, and plug it again. If you are using a router, unplug the network cable from the router, plug it directly to your modem and reboot your computer. If after the reboot the Internet connection resumes, the problem lies on the router.

If the status of your Local Area Connection says "Connected" but you still cannot connect to the Internet, there might be a failure with the Internet connection. Check the modem if the "Data" light is on. If it isn't, this means the computer cannot detect an Internet connection. Call your Internet service provider for assistance.

Tips & Warnings
A "modem" is a device that is directly connected to your phone line or cable connection. A "router" is a device that joins multiple wired or wireless networks, and is usually used when using a number of computers sharing one Internet connection.
A "Limited or No Connectivity" network error may also mean a failed DHCP (Dynamic Host Configuration Protocol) setting if you are using a router. A DHCP setting automatically assigns a unique IP address to a computer on a network. Enable DHCP by going to "My Computer" and loading "My Network Places." Click on "View Network Connections," right-click on your Local Area Connection and click "Properties." Choose "Internet Protocol TCP/IP," click on "Properties," choose "Obtain and IP Address Automatically" and click "OK."
