my computer was having trouble and I recently re-installed Vista Business 32bit. Now however, I'm unable to connect to the internet via a wired connection, nor a wireless one. I have an Hp Compaq 6730s, Intel Core 2 Duo. Under the device manager, "Network Controller" had a yellow question mark on it. Under Properties, Manufacturer is listed as "Unknown", so I don't know who's site to go to to find a driver for it. Can anyone help please? What other information do you need?
Please visit the manufacturer's website to download the drivers for your device. You can use google to find the manufacturer's website if you do not know it. In the support section download the drivers for your specific make and model of the device for your version of Windows.
Note: If the manufacturer only lists drivers for Windows XP and not for Windows Vista or Windows 7, that means the device is unsupported or incompatible with the unlisted operating systems.
