Connection dropping once or twice in an hour, not sure what to make of the logs

I'm on my 3rd modem now. Replaced an old one with SB6190 because I was having issues with network dropping constantly. Issue wasn't resolved so got CM700 and the issue continues. I think the problem is with the isp but I'm not sure how I would find that out. Can someone who is knowledgeable please look at my modem logs and tell me what's wrong with my internet?

Re: Connection dropping once or twice in an hour, not sure what to make of the logs

You also need the screen snip of the cable connections page. 

The T3 errors tend to be line issues through. And if you're on your 3rd modem, it probably isn't the modem.

If you have any splitters, amplifiers, attenuators in line, remove them. 

You'd want the isp to check the line.
