SYMPTOMS:

We have a computer that is running Windows 7. The computer has a wireless wide-area network (WWAN) device that connects to a 3G network. When resume the computer from sleep or from hibernation, the WWAN device cannot automatically connect to the 3G network.

CAUSE:

When you put the computer to sleep or into hibernation, the system does not remove the WWAN device until you resume the computer. This is not the expected behavior. When you resume the computer, the system also emulates the WWAN device. This race condition causes the problem.
