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?
It looks like COX offers "Gigablast". I just assumed in my area (Hampton Roads, VA) this was gigabit over copper as I don't recall COX trenching any fiber in my neighborhood?
According to here, Hampton Roads has both fiber and cable(HFC). Maybe try calling up and see if fiber is in your exact area? They might only mean fiber for Cox Business customers. It's a long shot but it would certainly fix your problem. Fiber doesn't get ingress like coaxial.
