It pays to move customer with old DOCSIS-2 modems to DOCSIS 3 ones as
they will even out usage on multiple channels instead of congesting the
one channel used by DOCSIS-2 modems.

Similarly, **if** a cableco has moved to 8 channel DOCSIS on the coax,
it may cost less to send new 8 channel capable modems to customers
compared to all the node splits they would need due to congestion on the
4 channels.


It may have just been marketing to deploy that Xfinity wi-fi thing,
thinking it would be seen as a marketing advantage for Comcast instead
of the marketing liability it has become.
