To share a cable modem, you need a broadband ROUTER, not a hub.
Without a router, the cable modem will see two separate PCs, and it's rare to find a standard broadband service that will handle that (at most, you can register the MAC (hardware) address of each and switch between with a reset).

You could also use a Linuxrouter on a spare old PC, but a broadband router is a nice tidy, silent, low power box.
