My friend has a Fujitsu Siemens Amilo Pro V 3405 laptop and he recently upgraded to windows vista ultimate 32 bit. When he upgraded, his wireless connection stopped working. He can't turn on the wireless connection for some reason so he's limited to using a wired connection. Why is it doing that? I downloaded/installed the latest software/drivers for the wireless hardware and it's still not working. What could be the problem and how can I fix it? It was working with windows xp so why not vista? and yes, the software/drivers that I installed were for vista.
