You can call me cheap but I'm trying to setup my home network so all my computers can use my newly installed DSL line. I'm using SBC Yahoo DSL and it only allows one computer to connect. At that point I knew I needed a router but choose not to get one at the moment. How hard would it be software wise to get other computers going software wise without some new hardware? How hard would it be to undo all of it once I get a router? Your input is greatly appreciated thanks.
