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. Here is a list of stuff I tried to fix the issue -
- Replaced router twice
- Replaced modem
- Plugged directly in through Ethernet, getting perfect speeds (100/10)
- 2 Cox Techs came out and replaced my line but nothing changed. Tested, and said I had 0% packet loss but I am still receiving it?
- Called cox multiple times and no help was provided.
- Done a lot of online research, and tried changing in-game settings to help it but nothing changed. Only thing that slightly helps is if I set my FPS to 30, but I can't play with that considering I use a 144hz monitor.
This is 100% a Cox issue as I used a TMobile hotspot and received 0% packet loss so it can't be anything on my end.
Please help, I don't know what else to do! Thank you!
Can you show a tracert to one of the game servers? Also, what model gateway or modem/router do you have? Have you tried disabling the hotspot and putting your phones in airplane mode when the packet loss occurs?
PS. The reason I asked what modem or gateway you have is to see if it has the infamous Puma 6 CPU which causes latency issues in games and VOIP and other things. See here if your effected. Run the test and if you see any Red (not yellow) then you have a Puma 6 issue. If it's all green, your not effected.

Nope. As per the wiki, it uses the Broadcom BCM4709A0. The SB6183 uses the Broadcom BCM33843D. However if you want to be sure, bypass the router, power cycyle the modem and test again. Even if it doesn't have the PUMA 6 CPU, it could still have TCP issues that the test tests for.

It's normalish? Hard to say what is normal in your area without "good" tracert to compare it to. However I doubt you will see your issue on a tracert TO the server. What you need is a looking glass (a ping/tracert server on Amazon's side) to tracert BACK from them to your public IP. This will show their downstream route, which is your upstream. Maybe I have the exact semantic backwards, but point is does Epic Games have a looking glass? Looking at the trace when on cellular, your latency is at-least 100ms worst. However it does show you goes through Zayo instead of Cox's direct Amazon peering.
What would you recommend I should do so I can attempt to fix the issue?
I would suggest contacting Epic games and have them ping your public IP and see what route they take. I am hoping that will show the actual packet loss and latency. A pathping also wouldn't hurt. If you/.Epic do find it's a Cox routing issue, try posting on DSLReports.com and see if you can grab a engineer's ear.
For now I am going to take a break. I will be back in the morning. Have a good night!
Hi, for some reason it never showed you replied until now, your response was invisible so I am very sorry for replying so late I am not sure what happened. Anyways, I have tried since December getting in contact with Epic and they never respond. Emailed them 4 times total and only one time they responded with a useless automated bot message giving me info I already knew. So that is a major problem I am having with Epic.
However, even if they did show me a traceroute there is probably nothing I could do as this is something on Cox's end - not epic. If I were experiencing packet loss on Fortnite only that would be a different story, but it is literally every online game I am playing on different devices (PC, PS4, Switch, etc)
