Wirless on laptop stopped working

My wireless on my HP pavilion dv6000 stopped working suddenly. Nothing out of the ordinary happened. The LAN runs through the house, the desktop computer works fine, and my laptops internet works fine when I plug the cable into it, but the wireless isn't working for some odd reason. When i search for wireless networks it gives me mine, and many, but when I start to connect it just takes forever, then stops trying to connect, and goes back to the list of wireless networks available.

 

I see, do this:

Start > Run > devmgmt.msc

Is there any device with a yellow exclamation mark like (!), what one?

Also run this tool:
