Not extremely tech saavy so I'll try to explain this as best I can: I have a computer (PC/Windows 2000 Professional) and it came with a built-in RTL8139A Ethernet card made by Realtek. I recently got DSL service for my home but when I try to connect the modem to the computer using an ethernet cable, it doesn't recognize the port or connection. I checked under device manager and it said the device was enabled. Downloaded the latest driver from the website but still no connection. Is this the right card to connect to the DSL modem and get on the net? Is there some other setting that I'm missing to enable it? I can connect the modem and get up and running with USB. And the ethernet cable works fine with XBOX Live. So my guess is that is has something to do with the card. Can anyone offer an suggestions to get me up and running? thanks.
