That is the main error that made you lose connection. Can you post your signal levels?

    A little over 53 hrs and the date and time have not been set on my modem to 12/31/1969 with the drop in internet coverage to follow. I have not made any changes to my residential setup but did notify COX about the date problem a little over 2 days ago.

    Shortly after the post above stating I have had no internet problems for over 53 hrs, the internet goes down and my levels have all changed.

    After COX outage to fix problems…

      It COULD be the modem. 

      Have they scheduled a tc to ensure the signals are in spec?
