I have the same problem, it's not an issue with AWS as some claim. The packet loss affects everything, including google cloud servers.
The issue is more than likely the node you are on is over subscribed, meaning the node will be at 100% usage causing you problems all throughout the day.
Secondly, Cox throttles traffic. You won't be able to fix this sadly, you have to switch ISP.
I want to give them the benefit of the doubt, but at this point it is getting pretty hard, and cox is the only isp I have in my area.
