ARRIS S33 cable modem event log shows 31/12/1969 date when internet connection is dropped

ARRIS S33 cable modem event log shows 31/12/1969 date when internet connection is dropped. Internet connection is re-established after a couple of minutes with the correct date and time. I have contacted COX and reported this problem with no luck. The modem gets the wrong date and time from a COX device that gives out the DHCP address and other information. COX has a piece of UNIX equipment that needs to be setup because it is sending the default 12/31/1969 date.

    The UNIX equipment that is defaulting the date to 1969 is the modem itself. When it is not online it can't get the Time of Day(ToD) signal from Cox to set it's virtual clock. Since the modem has no internal clock, it defaults to the UNIX birthday. The problem isn't the lost of date but the loss of connection that causes the loss of date. If you want to troubleshoot that, look at what the event logs are saying before the connection loss. T3/T4 errors?

        It's not a race. The more the merrier I always say.

        I was wondering how exactly the ToD system works. Does it use some kind of local NTP server at the headend?

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

    I am having the same issue and have had to call Cox three times today and they keep just having me run a speed test and telling me the modem is fine...I tried explaining the errors and event log and requested a technician, but keep getting the run around.

      COX will never get back to you regarding this issue. I finally got a hold of a tech savy person that aggred to place a note to my complaint so that the I.T. people would address the problem of the wrong date and time in their equipment. Now that issue has been taken care of it is now the process of them every day setting the levels for download speed then upload speed. Its a balancing act to do this properly and the contractors do not have the big picture in mind when they just throw attenuators in line and connect your house to the wrong port. I pay for the 1 gig and 100 meg package and it is not being delivered as of yet, just have to be patient.

        try replacing cable wires/splitters/barrel connectors, and see if that helps. Sometimes we get a bent cable wire, and that can cause all kinds of issues, causing the RF signal to get reflected backwards, and causing problems for all devices in the home.
