Strange Issues with Latency/Ping Spikes and Packet Loss

For the past 1-2 weeks, I've been having a major issue with ping spikes. Running a "ping google.com -t" will have my ping go from a steady stream of 10-15ms to a spike of 3000ms+ every 6th-15th ping. It's made gaming and voice chat near impossible.

Resetting my modem fixes the problem entirely - for about an hour, where the problems begin to resurface. Oddly enough, the problems appear to get worse with time. If I don't reset the modem after a day, the ping spikes will occur with increasing frequency and latency, and packet loss begins to occur. This is on a wired/ethernet connection.

I've called my ISP (Time Warner Cable/Spectrum in NYC) and get the usual response that my speed tests are showing up fine or to restart my modem. I've asked them to look at latency spiking, but they either can't or don't see any issues. A technician has come over to replace some wires and cabling, but the problem came back within hours.

Below are some photos of my ping tests, in order of time since a modem reset.

Now you have to do the ISP work for them. Run a tracert to these locations. Then run continous ping to various hops and see which the problem first starts in. You want to run them all at the same time. pingplot does similar but manually tends to be more informative.

Hop1 would indicate a issue with your router but it would be rare on Ethernet especially to get delays, loss you might get. Hop2 represents the connection to your house and is the most common point of problems. It can be the wiring to your house or something with the ISP equipment at the office, it can also indicate a overload if it is a shared media like cable modems...not dsl though.

Hops past the second tend to be something in the ISP network or even other ISP.
