Getting continuous packet loss and ping spikes throughout the day. Mesa Arizona

I have been troubleshooting this issue for two months now but it has not gained any traction. I have tried calling in multiple times but can never get past a level 1 support analyst. I have replaced my modem hoping that would make a difference but it is not.

I have performed traceroutes to confirm that the issue seems to be with a cox router -  5   201 ms    58 ms    48 ms  langbprj01-ae1.rd.la.cox.net [68.1.1.13].

Been a customer for a very long time and pretty frustrated that it is impacting my work and other activities. 

A couple weeks ago some cox trucks were working in this neighborhood and the issues subsided for a few days. But after that it has come back once again. 

I would really like to get on the phone with a support engineer that can actually help me out.
