I am trying to get a friends laptop to address the network. I fear this is an iterative process. I will list my efforts to date and the symptoms. The computer is a HP Pavilion laptop running win 2000. I have tried a pcimia card and a usb to ethernet adapter. Each initially would not alow ping and would not network indicating they were sending but not receiving. I uninstalled clientand protocol then reinsstalled after a full shutdown. I can now ping 127.0.0.1. The adapter lights the light on teh router the pcimia card does not both indicate send but no receive. Any advise is most welcome.
