So here's my setup. Really irritating ISP that won't let you do anything you haven't paid them to do. The modem is currently plugged in to the primary PC through USB, and won't send a proper signal over ethernet to a router, so I'm stuck running the modem to the PC. Previously, the PC was running ethernet out to a laptop, and that worked. However, I want to change that to run to a wireless router so we can connect more computers. But, it's being dumb. I've never had to use this setup before, so I don't know if there's anything fancy that needs to be configured in Windows (all computers are running XP). Any thoughts or suggestions?
