Hi I have the same problem as You
Windows 7 Home Profesional 64 Bits and Intel Centrino Wireless N 1030.
I found the solution:
Yesterday i remembered that i had installed Intel Proset Wireless 14.3.1 and when i updated it to the 15.2.0 version, intel my wifi stopped working, so i uninstalled the 15.2.0 version and reinstall the 14.3.1 version and intel my wifi worked again.
I hope that resolve your problem.
