SYNC Timing Failures, Fail to Acquire FEC, Unusual Power Levels, Work VPN Dropouts - Time Warner Internet

#1
This question is about "SYNC Timing Failures, Fail to Acquire FEC, Unusual Power Levels, Work VPN Dropouts", with Time Warner Cable internet and apps. Internet Only Customer, 200/10; Summerville, SC

Modem: Zoom 5370, Software Ver 5370-5.5.10.1

Router: ASUS AC 1900, Firmware Ver 2.112 Updated 2/11/19



Had problems w/streaming TV and the wife's work VPN dropping in and out today. Checked modem logs and found never before seen power levels and errors in the log (posted below). Rebooted modem and router without much change in stats and VPN still experiencing problems.



Background: About a month ago we had major connectivity and speed problems. Phone tech saw signal issues and rolled a truck. Tech ruled out any problems in home and called repair for line problems elsewhere. The next day problems disappeared and markedly improved signal stats. Also posting a screengrab representative of those stats for comparison.



Before Today





Today









Just checked modem stats again



Current Speed Test





So, what do the ~ -.8 to -3 dBmV numbers mean?



Thanks, Ken
