I am sorry you are having this issue but let me help you.
Based on the information there are some steps I want you to try. Can you verify the integration of the card on your computer? Make sure it has been set correctly.
Can you also try updating the BIOS on your computer? There may exist a compatibility issue between the computer and the wireless card.
Uninstalling through Device Manager is a bad idea. The BT software is installed by running setup.exe or the msi. So, always go through Control Panel | Uninstall Programs for clean uninstall.
Could you enable Bluetooth discoverable setting through Bluetooth Settings UI and check if other devices can see G72?
I checked for any bios updates. Turns out I have the latest version. The card is inserted correctly into the slot and works perfectly fine in a Debian O/S. It just doesn't see any networks in WIndows 7. The Intel Software reports that "Wifi is on" but "hardware radio is off". Unfortunately, there is only one radio button and that is reporting the radio is on.
Blue tooth works. It sees and can connect to my phone with no problem.
OK, What seems to the problem? Please describe clearly again.

The problem is the wifi part of the card. The Intel pro wireless softweare says the hardware radio is off when it is clearly on. There are no networks seen in Windows 7 but work fantastically with Linux. I posted the original message by booting with a debian based linux, using the 7260, and connecting to my network, but as soon as I switch over to Windows 7 there are no changes other than operating system. I don't see a single network.
I finally upgraded my operating system from the OEM Win 7 to a retail WIndows 8.1 and the card works like a charm now.
