Dell :: Inspiron 14R WLAN Card Disabled

I have a Dell Inspiron 14R running Windows 7 64 bit. I have had my PC from this past November; about 7 months.

I was using my PC, and suddenly, I started to experience wireless problems. I was unable to get onto the internet. Other devices on my wireless network are able to log on to our network, although that is irrelevant because my radio wasn't picking up anything at all, when it always had from that same location. The connection worked fine using an ethernet cable. After the problem occurred, my Targus Bluetooth mouse also stopped working.  This is what I have tried:

Going into Network and Sharing Center, disabling my network adapter, and then enabling it again. This usually does the trick. After doing it over 5 times, it never worked.

Doing a simple system restore. I attempted restoring 3 different times to an update within the last week, each of which failed (probably another issue altogether).

Re-installing my WLAN CARD Driver, and then restarting. This didn't solve the problem. Checking the Device Manager. It reported that the wireless card was running properly.Using the DW WLAN CARD Utility. It says under the Link Status tab, after Connection Status, Radio Disabled. I tried right-clicking the icon in my Notification Area, and then clicking Enable Radio. It then shows an alert saying "The WLAN card is still disabled. Use the wireless switch or hotkey to enable it." Pressing Fn + F2, which is also supposed to enable the radio, did nothing, with no action or sign whatsoever from Windows. I also tried running tests under the Diagnostics tab. All hardware tests passed, with the Connection test giving me this alert again: "The WLAN card is still disabled. Use the wireless switch or hotkey to enable it," and then failing. The same thing happened when running the CCX Client diagnostics.
