Internet outages wreaks havoc on VPN connections

This is a follow-up post as it seems my original post is locked for updates.   I often loose my connection which only lasts for several minutes up to an hour or so.   I am working from home using VPN and a couple minute outage will result in the VPN terminating.   I opened a ticket with COX and they replaced my coax running from the house to the the tap outside and stated they also replaced a component in the tap.   However,  I still experience outages.  I am posting my modem  logs in hopes that someone can review and provide a recommendation as to the root of the problem?

Thanks

    First, your original post was locked due to inactivity. All threads get locked after 30 days or 1 month(not sure which) so keep that in mind with updates. I had to "bump" a couple of my threads to keep them alive.

    As for your issue, the first thing I see is you are still using a SB6190, which is a known bad modem because of a CPU problem. Not saying it is causing your issues, since AFAIK the Puma 6 issue causes latency problems not signal errors, but it's something to note. If nothing else, Cox will push back on you having a "bad modem" or "old modem" if you escalate it. They might even try to up sale you to their Panoramic gateway.

    With that said, was the technician that came out a contractor? It sounds like the technicians are playing whack-a-mole replacing wiring and not tracking the ingress/noise. It requires a special meter and training. You might need a FCC complaint to get the case escalated to maintenance for the right technician. Before you do that, I suggest having a new D3.1 modem on hand so you can prove the problem happens with a new modem too.

      The technician that came out was a contractor.  You cannot specify who you want as you get who is available.  I will be ordering the Arris S33 tonight.  Hopefully that fixes the issue but I am a little skeptical.  If the modem does not fix the issue I will be switching to Fios.   Thanks for the quick reply.

        I don't think replacing the modem will fix the problem. I only suggested it to keep Cox from using that as a excuse. It stinks that it doesn't automatically escalate to a Field supervisor after so many appointments. It used to when I worked there. Now it seems a FCC complaint is required to light a fire under Cox's butt. If FIOS is in your area, I can see why you would want to switch. I assume Cox doesn't offer fiber in your area?
