What would be the cheapest and simplest way to use and old 486 66MHz computer as a router for a cable modem?
I would like to use it to route my cable connection to my main computer(upstairs) and my HTPC(downstairs) so I can transfer files between them, mainly MP3's.
It has Win98SE installed on it which runs slow but it works. I have Zone Alarm Pro I could use for the firewall.
What would be the easiest and most cost effective way to do this? What parts do I need?
Please be as thorough as possible cause I know next to nothing about networking!
