Ok, if anyone can help me with my question please respond. Can i still run internet through a modem without registering it through an ISP? Heres the situation: I live in a mobile home community and have recently discovered i have "free" cable running through my underground cable line. I hooked up a recently bought cable modem and discovered there is also internet being received. I just cant get past the local ISP's troubleshooting screen. The light on the modem reads a signal being recognized, but i cannot venture onto other websites. Does anyone know of any modems i can purchase that will receive signals without having to be registered? Or possibly universal MAC Id numbers?
