Hi, my HFC modem (Arris CM8200) has been regularly completely cutting out, with no lights displayed on the front. The power often won't turn back on for a long period of time when I unplug and replug in the power cable to try to reset it. I'm not sure if this is a power supply issue, but it is becoming quite frustrating. What steps should I be taking/who should I contact to deal with this issue?   Thanks, Brendan ... View more
