On my laptop I have a strange bug or something that fairly frequently causes wireless networking to become spontaneously disabled. Network connections drop out & all available APs disappear.
Using the Windows 7 troubleshooter (right-click on networking tray icon -> troubleshoot) detects the issue & correctly fixes it every time, but it takes a few minutes. I know what the resolution is & am wondering if there is a way to (quickly) enable wireless networking in Win7?
Here's a screenshot of the resolution screen that I'm trying to shortcut to.

, effectively turning off the wifi radio. Is there any possibility you are inadvertently hitting this button?
