Last month when I replaced my modem that I got from my cable company Charter I thought I was replacing it with the latest greatest future proof modem boy was I wrong, I was wondering why all of the sudden my Netduma was acting weird whenever I would do a ping test would get spikes that I even called the cable company and complained that there was something wrong with my line, what they don't know is the they giving customers a bad modem. Now that I have my old modem everything is the way is supposed to be. Thanks Zennon for the heads up. If it's not broken don't fix it.
