Looking for drivers for the Acer Aspire range can be a challenge. These drivers below are the 3 versions for the Acer Aspire 4750 notebook computer. There is a Windows XP, Windows 7 and also a Windows 8 driver for these notebooks. You can search this website for more laptop drivers and other wireless drivers if this is not the laptop that you have.
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.5.3.0.45' 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? Mediainfo 18.03 for mac free. To offer Vista on low power laptops is ridiculous. Next time I will request XP as the operating system.
