AFAIK cable modems cant support more than 10mbps because it is a
csma-cd shared medium over which they transmit. For 100mbps, the
number of collisions would be too high on shared medium. (thats why
you have switched ethernet now). To run 100mbps, they would need to
provide a dedicated channel to each household all the way to the
switch. And at 4.7mhz per channel, they will need a lot more cable
switches.
