Maybe somebody here wants to see if they can explain what is going on. For months now I have had short periods of poor service almost always in the evening. I have had multiple techs out who could find no issue. I have replaced every piece of equipment on my side of the connection, including the cable modem, at the suggestion of cox support. I have been put on "home monitoring" and been told nothing indicates any of the lines leading to my modem need to be replaced. I sometimes get error messages in the event log of the modem and have corrected/uncorrected packet counts but those do not correspond to the time of these interruptions.
Nobody seems to want to admit there is an issue or seems to get back to me with any information. I started documenting the issue at the end of December here https://www.dslreports.com/forum/r32616178-NV-Intermittent-latency-spikes-and-packet-loss
2020-03-02No uncorrectables or event log entries during these periods.
Have you tried getting employee Odog on DSLReports to look at your connection?
