"Missing wireless Somehow I've managed to make my computer lose it's wireless option,"
I've previously experienced this. Turns out I have accidentally uninstalled the driver of my laptops antenna. So, as what is suggested by other posters above, I suggest you go to the official site of your laptop and download the laptops wireless antenna driver there. Or if you have the drivers in CD, then just reinstall it in CD. There are hundreds of thousands of websites offering bogus drivers. So I suggest you read the manual and go to the official site mentioned in the manual.
