You pay for service, and the equipment is optional - the rental fee can be waived and you can provide your own equipment. The fact that your equipment works better is not a violation of their contract, unless they specifically said you would get 120Mbps with their equipment. Which they would never say, because there is no guarantee your computer can even handle that speed, and it's always been known that cable speeds vary per neighborhood and household. So, no, there's probably not a class action case. Just stop renting crap equipment and buy a DOCSIS 3.0 modem and a router that does at least 150mbps.
