Motorola MB8611 resetting - SYNC Timing and no ranging response received
Hello All,
Recently upgraded from a ~350meg Arris cable modem to a MB8611 since we have 1g service. No issues with the Arris modem. The MB8611 resets 6-10 times a day. Called a technician and he got rid of the splitters and cleaned up the line. I was at -4.6 to -6.4 on downstream except fot the OFDM PLC channel with -3.2 this channel had major corrections. Event log was SYNC Timing and no ranging response T-3 timeout received.
Lines where within parameters, but still had drops. Tech came out again checked the inside and ran a new cable from street to the house. That helped a little, but same 2 error and resetting about half as much. I took my cable modem and router outside and hooked it directly to the street wire to remove the internal house line from this. I now am only getting the SYNC timing error, but the power went up to 7.0 on the OFDM channel (see below)
This is the current event log. It has not dropped yet.
Any chance this is a modem issue? Any other troubleshooting ideas? Is it odd it needed more power when I removed the inhouse coax from the equation? I called Motorola support and they said those errors are related to the connection and not the modem.
Thanks for any help.

Placed modem and router back in the house. Back to original synch timing and no ranging T-3 issue. The power to the OFDM channel dropped to 4.6 from 7.

I am in the process of swapping out the modem. If the problem persists, I will try a different brand although the modem is approved for xfinity.
