What's wrong with my wireless?

I have a Vaio laptop from about a year and a half ago. Recently something strange happened.

I was uninstalling firefox and reinstalling it. I also Unintalled some old java updates and reinstalled Java.

Now whenever I turn on my laptop. The wireless card automatically turns off and I can’t get it back on. It is on when I start up the computer, but then turns itself off.

I tried getting the latest intel driver for the card and nothing has changed.

What can I do to figure out the problem?
