My original thread about this was locked with no reason, and after multiple Cox technicians and calls I am still receiving extremely bad packet loss on the upload side only. Mainly to games that use Amazon AWS servers. Anybody from Cox or community members able to help me?
Original thread -
Hello, I have been a Cox Customer for 17 years and a few years ago I started having very bad packet loss issues. I have spent hundreds of hours trying to fix this issue but it still happens even years later. I am only receiving packet loss (upload), 0% download packet loss. I am receiving low ping (for the most part) (30-40ms) and high packet loss (10-120%) in games such as Fortnite, Overwatch, Rocket league and more. It is happening on my PC & PS4. I have tried pretty much every solution you can think of.
(I am hardwired directly to the modem with Ethernet as well)
This is a Cox issue as I used a TMobile hotspot and received 0% packet loss so it can't be anything on my end. At least I don't think so.
Perhaps you could try running a traceroute to the IP of the server. Then, with that information returned from the trace route, start pinging the closest hop with about 100 pings using 512-byte packets and then continue to the next hop, etc until you start to see packet loss. Maybe, this could help to identify where the bottleneck is. Good luck.
Amazon Web Services servers don't return ping requests due to them blocking ICMP packets to prevent DDoS attacks, so that testing is unreliable. COX denies that this is their problem because there is no packet loss up to the point of the Phoenix server, 188.8.131.52. The packet loss occurs somewhere after that point. But this happens to so many COX customers in the Southwest, and has been happening to me for nearly a year. From my limited knowledge, I have to say that the "routing tables," or whatever controls the path our connections take to these AWS servers, is completely messed up.
With enough people performing this type of testing, a consensus could likely be formed as to the point(s) of failure. For example, is the bottleneck between the Cox backbone and the Internet backbone or is the problem somewhere out on the Internet backbone (i.e. Level 3)? I hope I'm making sense.
Going to be honest, not really sure what you guys are talking about since I am not a networking genius but I have tried I feel like everything in the book. Here is a tracert to Amazon AWS servers though (Fortnite) - https://imgur.com/0h1rSqE
The last COX technician I had out suggested that I get in contact with Amazon Web Services after replacing my line had no effect on the packet loss. I paid AWS $30 to access their tech support, but they ended up being no help either and said that my ping tests didn't show where the problem was occuring. Here is a PingPlotter test from today, https://imgur.com/a/0zZasP3 . Taking it at face value, I thought something was happening before hop 9, 184.108.40.206. When I told that to AWS support, they said that they couldn't help me any further.
