Cable modems need to be individually registered with the service provider. You can't just "stick one on" and expect it to work. 2 cable modems = 2 internet connection = 2 bills for service. Likewise you cannot split a DSL connection between 2 modems. Guaranteed to cause problems. You don't split DSL or cable at the demarc using the modem. For that you need a router to run ethernet or wireless to the different endpoints.
