said by neufuse:except in DOCSIS 3 case its not faster = more, its more channels = more... the cap claim was because they said the channel was congested... now you have at least 2 channels for downstream (and possibly up to 8 depending on chipsets, etc) so the DOCSIS 3 != higher caps kinda goes out the window because we ARE allowing more bandwidth for usage
On top of that since you have 4 or 8 channels assigned to you (and hopefully they mix the channels assigned to the users on a Node) the modem will prefer the non-congested channels that it is assigned so that congestion is less of an issue and thus the need to cap is reduced.
