Laptop driver PAIN (acer aspire)?

Could you pls provide the config of the laptop. Optionally, you can go to intel's site and download the drivers for the chipset which your motherboard has, like M945 or M965. And likewise, for the network controller, go to realteck webiste and search for your network chipset and download the drivers. As to the pci, I am guessing one should be the modem, which you can download from the specific manufacturer. Hope this gives you a start.
