Packet loss and latency in Online games

I am getting severe, intermittent packet loss while I play online games.

It seems to only happen when I interact with other players, usually 4 or more at a time. When I play solo in these games, even though I am still connected, I do not usually notice anything out of the ordinary.

For some specifics:

When I play Dota 2, one of out of every 3 or 4 times I encounter an enemy player results in packet loss. I try to move my character, but the game does not respond. I can still see everyone else around me moving, but my actions do not register until it is usually too late. Yesterday this happened to me so I ran a "-ping" command in game as quickly as I could. I caught the tail end of the spike and it showed 798 ping with 14% packet loss. I checked about 5 seconds later and it was back to around 60 ping with 0% packet loss. These spikes last anywhere from 2-5 or 6 seconds. 

In WoW, the same type of thing happens, except everything freezes. My actions don't register, but everything around me freezes as well. My ping during those times (from the game client) show ~800-1300ms.

I have experienced this same thing in CS:GO, Destiny on my PS4, Arma 3, Borderlands 2, and pretty much any game I can play online among others. But as I said, I only see issues when I am around those other players.

I have called Cox support and the tier 2 tech said he saw some issues with my connection, so a tech was sent out. The tech basically told me that it's a cabling issue, but since I live in an apartment complex, we can't do much about it because we would have to rewire a quarter mile of cables.

I have run a few tracert's to Valve's server that I play on most, located in Seattle.

I also ping'd that same server for a bit. Here is a shortened version of the results with the most important parts in it.

I am not sure what exactly is happening overall. I am willing to accept that it may indeed be my apartment complex's wiring, or even my own hardware. But I would like to get to the bottom of this if we can.
