I have a internet connection through cox communications, for the past year or more I've had issues with packet loss sometimes it's around 10% and higher but for the most part it's about 1%. I've complained to them over and over and they tell me the issue is not with them. I've ran some trace routes using a linux box and mtr and uploaded the photo to the post. The first host is my router (cisco 2821) the second host is some cox device even though it has a private IP, it is nothing inside my network.
I was hoping someone could take a quick peak at my config and see if there is anything they see that could possibly cause this issue. I don't think Cox is going to be able to help me much as the last tech (a senior tech) told me the issue was my cable modem was plugged into a power strip and the power strip splits the voltage 6 ways causing the cable modem to fail....so given that comment I don't think I will be getting much help on their end.

I just want to make sure I don't have something goofed up on my end before I point the finger anymore at Cox.
Thank you for the help and input.
