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?
