This is the model Humax was showing at their web site. I guess people assumed earlier specs looked like it showed a DOCSIS 3.0 cable modem built but now it just shows support for DOCSIS 3.0. Sorry I should have said the cable modem wouldn't have been used for the Internet just for making connecting the clients better and faster?If based on past experience I wouldn't expect any difference between the -100 and -500 that the customer would see. I would also guess that there is no cable or DSL modem built into the box since DIRECTV usually doesn't include anything more then necessary to provide their service.
