    Try Pingplotter to graph packet loss over time and to trace where it is occurring. To share the data, go to File > Share > Create Share page and post the link. Also force a IPv4 trace by entering "ipv4:" before the server name in the target field or use a IPv4 target like 8.8.8.8.

    Well it is to document the problem, so as long as you want. It looks to be happening pretty regularly almost as if it isn't random. It also seems to be occurring on the second hop, which is between your modem and Cox(CMTS). That would fit the Cox infrastructure excuse.

    Could you post/check your signal levels? Assuming you have a Panoramic gateway, you can find them at 192.168.0.1 > user:admin password:password(unless changed) > Connection > Cox Network. Just need the downstream and upstream levels along with SNR and uncorrectables. Downstream should be between +5 and -5 with SNR above 35. Upstream should be under 50.

      Upstream index 5 is off the charts

      For Downstream it starts to go out of range at Channel 25. 25-60 are all this low
