it was fine as recently as Sunday, but yesterday I stopped being able to connect to my router. I've been in the Wireless Utility and the "enable radio" is checked, yet the icons in the system tray still say I cannot connect to the wireless network and the radio is not on. Another computer in the house connects fine to the network. Is there anything I can do? If it sounds like something is "blown," would it be corrected by purchasing a new PCI card--that is does that contain the radio function? Before I go ahead with something like that, I want to be sure that's likely to fix it. Thanks.
