I had the same problem with my 3680. Vista was so slow I had to go back to XP. The 3680 handbook says that the wlan chip is Intel PRO/Wireless 3945ABG. I tried all the Intel 3945ABG drivers from Acer but no go. I did a hardware listing under Fedora(/sbin/lspci) and it said my chipset was Atheros AR242x. I got the 'Wireless Lan Driver Atheros 802abg Atheros ver.188.8.131.52' from the Atheros website and the wifi now works. When I tried to load Acer Empowering Technology which was there with Vista it said this programme only works with Intel chips?? Am I misunderstanding something here? To offer Vista on low power laptops is ridiculous. Next time I will request XP as the operating system.
