Yea, I didnt mean to say that DOCSIS 2.0 mean it would work. Theres several parts to working with the modem. It needs to ATLEAST be DOCSIS 2.0 compatible and have a firmware built for the modem. Which from that posts, it WILL work. That will only make it run like a SB510U though. Then you need to have channel bonding. Then you need support to spread bandwidth over those channels. And usually you get a whole bunch of other boosts to performance around then.
