Intermittent no IP on DCX 3510 in east Van. I have been experiencing no IP without any change to my hook up for the past several weeks. I have HD PVR on one one arm of 1:3 spltter shared with internet modem and one other downstream splitter. I have rebooted HD PVR many times and it does not come back. Perhaps comes back 3 - 8 hours later. Is any one else having these issues with DC 3510? Technician says it is due to weak signal but we have had this same setup for 2 1/2 years without previos problems.
