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.

This happens because power management turned off wireless capability when not in use. You can change this setting:
- Open Network Connections
- Right-click on the wireless connection and select Properties
- Click Configure next to the wireless adapter
- Click the Power Management tab
- Uncheck "Allow the computer to turn off this device to save power"
Like this:
What I think is that you must have accidently pressed the wifi off option from "Windows Mobility center". Try opening it from "Windows Mobility center". You can open "Windows Mobility center" by opening control panel and type "Windows Mobility center".
3Sometimes none of above will be useful because the wireless adapter has been disabled from BIOS, in this case you need to enter to the BIOS and set it as default, then login again and go "Windows Mobility Center" through Control Panel and you can turn the wireless adapter ON/OFF.
1My wild guess: Your laptop has a software- controlled button for toggling wifi ( possibly on the keyboard) which you accidentally press, disabling the network adapter. In that case you should be able to turn it on by pressing said button.
I used FnF2. The F2 on my laptop has a little antenna icon. Must have hit this by mistake once!
This toggles the WiFi on and off.
