Windows 7 Users soon or later will face this gifted bug of Muntiple Network Detection. In your LAN connection, There will be two connections : Home network and Unidentified Network. Due to this Problem, the internet access is disabled.

For the remedy of this, i used to disable LAN and re-enable it. But i Finally found the solution that its was one of the crappy SERVICES of Microsoft [LOL]. So simply Disabling this service will solve the problem

From Run> msconfig >>under services tag >> tick off the first Alpha numeric service like [#4H5J845430HF ..]

or

Run > services.msc > find the alpha numeric service and disable it from PROPERTIES.

!!IMPORTANT: You Can only disable it when it is active. Means You only find the Alpha Numeric Service in Services when you have muntile Unidentified and Home Network Detected and No internet Connection!!

Restart your Computer an you never have to see this windows 7's crappy SERVICES;
