Hey I upgraded from WIndows HOme Premiun to Ultimate and everything seemed to be instaslling fine..but I realised after insatllation that my Wireless swtich is not getting enabled at all. It is always in the red position .even when I press it multiple times nothing happens, and thus I cannot discover any wireless networks. thought that this is a driver problem and tried to install HP wirelless assistant program from internet. But even this did not help me. Can someone please clarify on this ?? Ajay
