The Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem is the best cable modem for most people, and for those getting clipped by modem rental fees, it pays for itself.

One final note: If you’re on one of TWC’s new Ultimate 200 and Ultimate 300 plans, you’ll need to use the new Motorola SB6183 modem to really max out those download speeds. It’s worth checking to make sure you’re actually getting those speeds, since you know, TWC’s infrastructure is garbage. - Gizmodo
