I have had Road Runner for two years. At the time I was setup I was given a Motorola CyberSurfer Wave modem and have been using it without any problems since. At that time DOCSIS was not used in my area, DOCSIS is now used throughout the system. My friends who have gotten their service within the past year have all been given the Toshiba cable modems. Time Warner will swap out my modem if I want, but I do not know if there is any benefit to doing so. All opinions are appreciated.
