It usually means you are about to get a speed upgrade that will go beyond what your modem is capable of delivering. In that case it is possible you could have a 1st generation 4x4 modem (so it can bond 4 downstream and 4 upstream channels).

Comcast does not provide any speed on residential lines that DOCIS 3.x cannot accommodate. It is like requiring Formula car to drive on a gravel road in Alaska.

Different modems can use different numbers of DOCSIS channels. A 4x4 DOCSIS 3 modem is only capable of, at most, 150Mbps and on average 75-100Mbps. A new DOCSIS 3.1 model can do >1.2Gbps.

Yeah, no.

https://en.wikipedia.org/wiki/DOCSIS

3.0 spec does up to 1.2Gbit/sec, just like Comcast. You know up to 200Mbit/sec, which is more like 20 because of all the "extreme complexities of the internet service".

[virtuallynathan]

DOCSIS 3.0 supports 38Mbps per channel, which is in the table on wikipedia. Not every modem is capable of 1.2Gbps - The fanciest modem out there is 32 channels, which gets to your theoretical 1.2Gbps. If you have a 4 channel modem and expect consistent speeds of more than 100Mbps, you are SOL.

I wonder if your customers would be happy enough without the speed upgrade if they weren’t wasting bandwidth downloading code they never wanted to run in the first place
