One of the more common problems is the the built in adapter goes bad. Buy a USB wiFi adapter and try using that. They are cheap and easily available.

This is a pretty common problem and there has been a lot of questions and discussions of it. Do a search for it and many of the answers can probably help you.

Have you restarted the laptop?

My HP compaq does this exact thing when I mis-treat it and it can take up to a month before I finally resolve the problem.

If you are connecting and dis connecting all the time it ma have an affect on the computer.

To avoid that I never shut mine down or even turn the sreensaver on just in case!

If you know that you can connect to other WIFI using the laptop, then I might think I'd forgotten to enter the WPA or other security password when attempting to login to the router. Other than that, I'd suggest contacting HP for troubleshooting advise. Maybe jsut need to update a driver...
