Packet Loss, Dropped Connection, Over a year

I've had constant packet loss, latency issues, full on dropped connections for over a year now with Cox. I've wasted time on the phone for hours changing routers, modems, having technicians come out only to tell me that my internet is perfectly fine.

I cant video call (for work), game, or even browse the internet. I'm hoping someone can help.
