I have just set up a network using two computers: a desktop running Windows XP, and an Apple Macbook Pro running OSX Tiger. They are both connected to a Belkin F5D7633UK4A wireless router, with the PC connected via an ethernet cable, and the Apple connected via wireless. The aim is simply to get an ADSL internet connection to both systems, at normal capacity.
The main situation is this: the Apple connects to the router with no problem, and can get a very good signal. However, the PC registers an extremely poor connection, with extremely slow page loading times. Most of the time, pages do not load at all. The lights on the router show a perfectly working connection. The router itself is new, as well as all cables. The configuration of the settings in Windows have been made after following instructions given by the ISP provider.
If it helps, the ISP I am with is Virgin.net in the UK. The ethernet cable is connected to the PC through an nVidia networking card (as mentioned in Network Connections).
It is absolutely vital that the PC has internet connectivity, so this is an urgent request.
