In order to post here you had to get to the internet. Use this computer to find the drivers if they exist at acer.com
I installed a faster hard drive and windows 7 ultimate on my aspire 7741z-4433. I went to the acer driver download site from another computer and downloaded the ethernet controller driver on a flash drive. I put it in the downloads folder and tried to install it but it will not install. I need all the drivers and updates but can't get to the internet. Any advice or tips would be appreciated.
