My Internet Keeps Shutting Off?

Nikushimi Asked: My Internet Keeps Shutting Off?

I have a dell laptop, and since yesterday the internet has been shutting off. Not the connection itself though. You know when you hit the "F2" button, and that X appears to let you know you shut if off. That's what my laptop is doing, but I did not hit that button! It happens after I've been using my computer a while, it just started happening so I can't be sure. But it cuts off all connection, except this one, that has no signal. What does this mean, and what can I do to stop it. Do I just need a new one all together? Thanks, very much!
