I am trying to help my sisterinlaw move from dialup to HighSpeed internet access.  She has a Dimension 4550, running Windows XP (I know it is old but still works for her).  My problem, when I connected the line to the ethernet card nothing happened.  I found the card was not turned on.  I turned the card on and it now tells me NO DRIVER Found.  I tried to find it on the system disc but it says it is not there.  What driver do I need?  Your help is appreciated.
