My laptop cannot detect Wireless networks nor interface!

Hi I was using my laptop for ordinary use surfing YouTube. When all of a sudden i shut it down and turned it back on and the wifi switched was on but the light was orange which indicates off. I could only connect wired connection. I went into Manage Wireless Networks and says Wireless is not currently enabled. Someone please help. And this is all comes up in device manager its in the picture and notice the bar in bottom right it only gives me ethernet connection option.

I have a Compaq Presario F572US

Im sorry that is another computer on the laptop that has the problem im using 7 64 Bit. I tried both but no luck at all. I downloaded this one : Broadcom Wireless LAN Driver for Microsoft Windows Vista Compaq Presario F572US Notebook PC - HP Customer Care (United States - English)

I did it and nothing worked. -_____-

No still the same nothing changed

And No i have no security software installed. And I even re installed Windows 7 because i barely had anything on it and still the same.

Do you think it might be a hardware problem??

No luck. I download the chipset drivers for my laprop model and installed but still nothing. And tried the keys and still nothing. And the switch is on the on side but still shows that is off. The light is off even though the switch is switched on.

I guess it is a hardware issue.

Thank you i see what ill do.
