I have a HP Pavilion D4990Y that I haven't used for about 6 months now. I just decided to set it back up but it will not connect to the internet. My laptop will connect, however. The computer cannot find any connections even though I know there are plenty that I can connect to with my laptop at my house, including my own router. The computer's radio search device for a connection is on and the router is working fine. Any idea on how to fix it?
