Ok, here is my situation. I am getting cable internet access installed this Friday and I am purchasing a Motorola Surfboard SB5120 modem and a wireless router. I have two PC's that I have to connect, and I am doing it wirelessly. One of my PC's will have the modem and router attached to it. My main question is, do I need a PCI adapter or whatever on my other PC?? It is a newer Dell PC, does it already have one?? How can I check??Please help me out, I am new at this networking stuff.....Thanks again
