Warning! This post is VERY long winded and I apologize in advance. Hi. I have an Imac and PC (with WinME) in the same house. I use roadrunner cable internet on the imac and dial up on the PC. I am now in the process of connecting both computers to share the cable service. Roadrunner told me this is no problem I just need a hub and the RJ 45 cable for each computer. I now have the two computers and the cable modem hooked up to the hub. The Imac is connecting to the internet just fine but I'm having problems with my PC. I called Apple tech support. They say I need a router instead of a hub to make a PC/Imac cable internet connection work. I then called Roadrunner and they still say that either a Hub or a Router will work but that they cannot help any further. My set up is as follows: The Toshiba Cable Modem is connected directly to the four port hub and the Imac and the PC's ethernet cards are connected directly to the hub as well. Here's my question: Can I connect these two with a hub or do I need a router? My other question is do the computers really need to network to make this work? I've activated the home networking program in my PC but am afraid to mess with the networking program in the apple.
