I have 3 desktop PC's that I would like to network together. I do not have high-speed internet and each PC has its own pone line connection. All I want to network them for is to share files, share printers, and play multiplayer games. I read that you can just buy the wireless PCI ethernet cards for each PC and that you dont need a router if your not sharing broadband. Please tell me what hardware I will need to set up this type of network. Thank you.
