Correction: D3 supports PowerBoost, however the tiers that TWC provisions to D3 modems may not. I know this for a fact since I've used Comcast with a D3 modem and gotten some wicked PowerBoost numbers before (35/10 on a 22/5 connection)
yeah I get 30mbps on a 30mbps connection -- Well, does your car at least turn into something else? Sometimes I turn it into a trashcan. Hmm...
