I am happy to answer any questions that are asked:

It is a Dimension 4700. Windows XP. Yes, the network adaptor shows up in device manager and as a good connection in the local area connection status window. I just put in the Dell disc as I did for the last Dell computer and installed everything with a check mark next to it. It worked before just fine. I don't know what chipset is or whether I installed that at all or in what order.

Yes, I connect to the internet by ethernet. It goes from my computer to a dish on my house - this dish transmits to a dish on a mountain nearby - which then goes down to a landline. So, it's not going to space like DirecTV or Dishnetwork.

It sounds like all the drivers are installed, since the device shows up in Device Manager.  Since I am not familiar with the type of setup you have, I don't know if I can be of help.  But, as a frist step to help troubleshoot this problem, go to Start > Run and type cmd then click OK. In the command prompt window that opens, type ipconfig /all then hit the enter key. Write down the output from this command or select it and save it to a txt file, then copy this output into a reply to this message.
