Windows 7 Wifi stuck off

[knighthwk001]

Ok so I have a Toshiba satellite laptop running Windows 7 64bit and recently it crashed. I fixed it and everything worked fine, except for the Toshiba utility at the top of the screen that allows for shortcut keys such as changing the brightness, switching wifi, etc. by pressing the fn key and a F key. The utility shows up, runs, and works fine, except the wifi option is gone. I tried using fn+F8 (the keyboard shortcut for wifi) and it didn't work so I uninstalled the utility completely, went to Toshiba's website, entered in my computer's model and re-downloaded it. It works fine again, but still no wifi option. In my status bar, my wifi says it is off and if I go into control panel I can disable/re-enable it but it still won't work. I re-downloaded the drivers for my network card, and have tried literally everything. My laptop does not have a physical switch either, other than the keyboard shortcut that no longer works. I contacted Toshiba and they directed me again to the same utility which they said has the wifi option, followed the steps through the phone, but the option was still not there. Does anyone have any idea how to bypass this? It seems my network card was switched off and cannot be switched back on no matter what since every way of doing so is gone. Is there any application to bypass it or a wireless radio application to force the radio on? Thanks in advance!

Knight, welcome to sevenforums.

Would you mind telling us a little bit more on what caused the computer crash before, and what you did to fix it?

For right now, could you type 'cmd' in the start menu search without the quotes, right click it and click 'run as administratior'. When the prompt comes up, type SFC /scannow and let it do its thing, then close it.
