Download the Intel Centrino Ultimate-N 6300, Centrino Advanced-N 6200, Centrino Wireless-N 1000, v.13.2.1.5, A01 drivers and save them to your desktop.
Make a system rstore point.
Start, control panel, device manager, right click on Intel(R) WiFi Link 1000 BGN, left click uninstall. Tell it to remove the drivers and software.
Restart your computer.
When you log back in, the new hardware wizard will try to install the drivers but fail. Install the drivers saved to your desktop.
Try to connect. What happens?
If you cannot connect, go to a hotspot in your area and try to connect. Can you connect?
