Any Network Engineers in here?

Those who play with me on Battlefield know that I've been plagued by severe lag which normally occurs in early evening hours.

I'm pretty certain I've isolated the issue to packet loss/severe delay at the ISP level which occurs in spikes intermittently and most often in the evening when my neighbors start streaming.

Packet delays are hitting the 200+ and higher and sometimes sustained for a while with total packet loss occasionally exceeding 10% for a given period of time.

I'm measuring packet loss using packetlosstest.com which seems pretty good for testing.

I can run a speedtest and everything looks pretty normal with speeds hitting over 700Mpbs/30Mps (I have asymmetrical Gb "Gigablast" with Cox over standard cable) but with severe packet loss.

I have isolated the problem to being external through normal troubleshooting and using multiple computers. I've even tested by loading the network during the day when things are good while testing and it still holds up fine. There is no correlation between LAN loads and the packet loss.

I have a Arris cable modem and Netgear XR500 router running Dumaos. I've tried bypassing the router and changing the QOS settings but there is no correlation. Performance is very good even on a loaded LAN during off peak hours although I still log the packet loss it's just more intermittent.

In gaming the lag appears as ping spikes from normal double digits into the 200+ range accompanied by heavy warping and inability to move or control the vehicle I'm in.

I need suggestions on how to get Cox to pay attention or if they can even do anything about it. The neighborhood is about 20 years old and I suspect part of their gear may be that old.

So I would call Cox and ask if they are seeing drops on your connection. They should then dispatch a tech for free. the issue might be a few things... cable connections above ground are starting to degrade and need new connectors put on. That fixed my recent issue which was the same as yours.
Also it could be one of the head end units on your node is starting to fail. The techs would be able to identify signal level issues on your run and others around.

I would get a tech out to verify your run from the modem to the box on the street and replace any cable connectors that can to see if they are failing due to age.

Thanks,

I forgot to mention they already dropped a new line to my house and tested the signal between the street and my modem which was very good. There was little to no improvement in performance.

If you would like, DM me and we can schedule a time to figure all of this out :)

Thanks. The culprit seems to be explained here. It's not a signal issue on my end but these two channels seem to be the problem:
