Is it just DNS traffic or all traffic? Hard to see the netprobe data because Cox doesn't allow you to click on a picture to zoom in anymore. Can you use Imgur? From what I can see though, packet loss is less then 1% and the tracert either doesn't show the issue or the issue wasn't happening when you ran the trace. Try using Pingplotter to monitor latency/packet loss over time. If you can't use Pingplotter for some reasons, winMTR is another choice, but not as good IMO.
Also, can you describe your network setup and config? Why do I see IMAP and POP traffic between 192.168.0.116 and 192.168.0.177? What is device is 177?
Last, to see if it's a router/gateway issue, try putting the gateway in bridge mode and see if there is a problem.
