Horrible Ping Spikes (Tried many solutions)

Copy paste from a different thread:

I've been battling for months and was finally told that it is a node issue and there's nothing that can be fixed on our end.  It really is unacceptable but my apartment complex is Cox exclusive.  Games are a big part of my life and I'm straight up going to have to move because Cox apparently can't provide a reliable enough service to play on.  Luckily ATT has fiber near me with 1gbps up and down (for less than I currently pay), so I'll make sure that's an option at my next place.  

And to the Cox Support people on here, I know you're doing your best, but I've had every tech come out and have been escalated to the executive number, and have been told that there is no fix at the moment.
