Hi, all! Our laptop, HP Pavilion DV9000 (Vista Home), is equiped with a wireless wi-fi card. Suddenly, there is no connection to our router, hence no internet. I went into the System, Device manager, to check the status. I could not find anything on the wi-fi card, just the standard network controller. I tried to open HP Wireless Assistant program, it would not launch. Can someone advise if it's a hardware problem, that the wi-fi card needs to be replaced? Thanks so much in advance!
