Like Motorola870 said you are much less likely to have problem with DOCSIS 3.0 because with 2.0 you are only relying on one single channel. So if that channel gets congested then you get speed slow downs.
However with DOCSIS 3.0 and TWC you are going to have at least 4 downstream channels so if one is more congested they can utilize other channels that are not as congested. So all 4 together they are able to get constant and consistent speeds. You can still have speed problems but it is a lot less likely.
That is why you can see HUGE changes in performance going from a DOCSIS 2.0 modem to a 3.0 one. If you are already in a good service area for 2.0 then you won't really see any real difference. In some cases you might see performance decrease because Powerboost only works with 2.0.
Can you define good service area? Is that uptime? If so, then yes, it is fine. To me, yeah it works well during non-peak hours like right now at 9 AM PST: 1.8-2 mB/sec from Steam. During peak hours, I noticed download speeds can go down to about 200 kB/sec.
Does TWC have DOCSIS3 modems for those with digital phone service? I think my parents still use a DOCSIS2 cable modem (Arris TM502G) from its summer's installation.
