Repeating Timing Synchronization Failure
Greetings all -- I'm in NYC. I have been experiencing timing synchronization failure messages (failed to acquire QAM/QPSK symbol timing) from my modem (TP-Link TC-7610 DOCSIS 3.0, 4 years old, Firmware Version: v1.1.0 Build 20160920 Rel371550, Hardware Version: 1.1 ), at least twice daily over the past week. During these events, the network connectivity drops and the router takes at least a few minutes to reconnect.
I thought it may be an issue with over-heating (the modem was warm to the touch and partially obstructed) but I am still observing errors even after giving some more room. Environmentally, my building momentarily lost power for maintenance on July 22 and there was a partial black-out in the city on Aug 7 that lasted about 45 minutes in my neighborhood. We have also had some impressive lightning storms recently.
Log and connection status pasted below. Any thoughts?
