Re: [AZ] Massive Packet loss this week

I would suggest that you ping a target within the Cox network. A good place to start might be the third hop in your screenshot at 68.2.8.37 to see how local the issue appears to be. If packet loss is evident take more screenshots over the course of several days to establish some history of the problem and contact Cox tech support for a residential visit. Show the tech your screenshot(s) to assure he/she understands that the issue is within the Cox network.

Does you modem indicate poor signal levels, an SNR issue, or a high error count?

That is what I have been doing over the past few days. Hop 6 in that screen shot seems to be the problem area. It has consistently dropped packets over the last few days and has had 100% packet loss many times but is usually between 25% and 75% packet loss.

I am getting some errors and critical messages in my modem logs but I do not think they are related:
