Very good points, John.



> Cable companies prefer customers to use cable modems that are over provisioned by a couple channels.  If you???re subscribing to a 300Mbps plan, and have an 8 channel DOCSIS3.0 modem, then yes, the 343Mbps on the eight channels will let you download at full speed ???. as long as none of your neighbors are also using any of the channels you???re locked on.  By over-provisioning, they can better guarantee that you???re getting the speed you pay for, and why they sometimes bug you to upgrade your modem.
