I have an old Dell Inspiron 1100 that was given to me. Reformatted Windows XP and now I can't get on the internet through the Ethernet adapter from Cablevision. On device manager the following drivers are missing: Multimedia audio controller; PCI Modem; and USB Controller (although I downloaded a Broadcom USB controller). Would this effect internet access? If so, how do I remedy? I have already been to Dell's driver downloads and don't see these drivers. Thanks.
