Internet keeps dropping out, losing signal, Modem shows errors

I have had issues off and on since Feb 2015 with about 6-8 techs coming to my house, 2 different modems, and many other things checked/done by Cox to correct the issue.

I continuously have issues with my modem dropping the internet or low levels which affects my router and it drops my wireless and wired connections. Most recently last night I received a broadband outage notification from my alarm company and when I check my modem logs there is a error around the exact time and as well in my router. I then receive a notification about 2 hours later that broadband was restore and similarly in my router logs it shows internet connection restored.

They have checked all wiring from street box to modem and even ran a drop line from the street direct to the modem, Cox has tried a couple of their own modems and even replaced mine for free. The issues resolved after rebooting everything for a couple hours to a few days.

For the Cox techs on here you will see in my account numerous records of me being told it is something on Cox end and also some saying they see nothing wrong because by the tie 2-3 days later when they send someone it is working.

Here is what I see in my Modem for the last 3 days- note that I didn't have any issues yesterday when using the internet
