Cox Latency And Speed Issues

Figured I'd try to put together all the packet traces and stuff for cox in one spot to try to get my issues figured out.

Basically, the issue is that during prime time every day, my internet becomes basically unusable for any media usage. Burst speeds of 28Mbps are my normal speed during primetime, when I'm expected to get 100Mbps+ on my current tier. These tests are using their servers! Using Speedtest.net, I get wildly inconsistent speeds - from <10Mbps to >45Mbps during primetime.

WoW and CS:GO have been unplayable, with sustained reported ping of 150+, spikes in the 400 range, and felt latency of around 1 second or more. Streaming videos buffer constantly. I had a SB6120 modem. I replaced it with a SB6183 modem on 11/4/2014, after @coxhelp suggested I may need to get an 8-channel bonded modem. This new modem is up to 16-channels. But I still only see 4 bonded, UP/Down.

11/3/2014 - 10PM Pacific - 30 Mbps Cox Speedtest
Router utilization during 11/3/2014 speed test
11/4/2014 - 7:15PM Pacific - 25Mbps Cox Speedtest
11/4/2014 - 9:30PM Pacific - traceroute to valve servers
11/4/2014 - 9:30PM Pacific - 18MBps Cox Speedtest
11/4/2014 - 9:45PM Pacific - Cox Gateway 150ms Pings
11/5/2014 - 8:45AM Pacific - Non-Peak, 110Mbps Cox Speedtest
11/11/2014 - 7:45PM Pacific - <10Mbps, 500+ ping, 200+ jitter, Router Status

My passive utilization is essentially zero. This same setup used to hit 75+ 24/7 at my old apartment, and sometimes hits 80+ here with Cox's "doubled speeds", but that is only ever at like 8am on a weekday. The fact that during prime time I was AVERAGING 100ms ping to the FIRST HOP outside of my modem, is unnacceptable. A half hour later, I'm still averaging near 50, with spikes every 8 pings to well over 100ms. For the first hop. For comparison, Menlo Park Comcast, same $$ package, is sitting nicely at about 6ms ping to first hop during primetime.


Our initial findings on 10/3/2014 with one traceroute was that there was a ping spike in AT&T's backbone network. Cox rep seemed to be brushing it off as not part of their problem anymore. Really, they should be talking to AT&T and issuing their tech a ticket saying they are causing routing problems, or to route around the bad connection. However, that can't be the only issue. Obviously this neighboorhood's node is just insanely impacted during prime-time hours.
