If other computers in your home network can access internet then on your PC is already virus that is blocking internet connections. Simplest way is to format system or all HDD and do fresh windows installation.
If it was working before, then please make sure you don't have any viruses or other malware as they are known to cause internet connection problems. If your machine is clean then you can try to reestablish the connection by right clicking on the LAN icon and click on "repair". If that doesn't work, then try to reinstall your internet connection. If this helps, please do rate me. Thanks

It is cause by a very serious virus called "Conflicker"
Try to Do a upgrade of 7 (Free upgrade from Microsoft).
The upgrade does not delete your files, it should detect and erase viruses and the startup is quicker. (22 secs on my Dell Inspiron 2200 with 512MB RAM!!!)
Currently, the only other solution is to do a complete re-install.
hi there, i had kind a same problem with u, the only difference is mine shows "connected" but i can't surf the internet when others in my network are doing just fine. 1st i tried to uninstall my LAN card driver and the reinstall it back. It worked, i can surf the internet but only for a few minutes. So i installed a firewall, in my case, i installed windows defender. After reinstalling my LAN card driver, i realized an unknown program tried to change some of my LAN driver files, so i denied the program access using windows defender. The problem solved !! Maybe it's a virus or spyware, i don't know because before installing windows defender, my avg and antispyware don't detect any virus/spyware. Hope this help, gud luck
