[KS] Intermittent packet loss.
I posted earlier( »[KS] intermittent periods of packet loss/extreme latency ), but the topic is too old to reply to. I'm still seeing the same issue. Long story short, there was another event last week where I had between 30% and 70% packet loss for four hours straight(oct 17 from midnight til 4am), and I still can't get cox to send a line tech out(I even threatened to cancel my service, maybe if I call the billing department they'll believe me about that.) So far there have been 5 normal field techs out here that were unable to find any problems due to the intermittent nature of the problem(they've replaced the cable modem twice, as well as the buried line between my house and the pedestal.
It seems like only upstream packets are affected(upstream throughput drops from around 5 mbit to around 0.2 mbit), but the packet loss is so bad even basic web browsing is intolerable, worse than dialup.
Here's the signal level during the event: »i.imgur.com/I47nN.png
--- google.com ping statistics ---
2070 packets transmitted, 1282 packets received, 38.1% packet loss
round-trip min/avg/max/stddev = 25.670/28.069/44.573/1.954 ms
here's from the computer to the modem during the same event:
--- 192.168.100.1 ping statistics ---
96 packets transmitted, 96 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 1.983/2.157/2.813/0.124 ms
Here's a trace:

Any ideas about how to get cox to fix the problem, or any good alternative ISP in the wichita area?
I have no problems in this wichita location. you absolutely need the DOCSIS 3 cable modem or later DOCSIS 3.x cable modem if you can, you can buy the DOCSIS 3.0 cable modem, Since I assumed that you have the old DOCSIS 1.x or 2.0 version.

So a few techs later, and one of them notices a skew problem at the pedestal. They're sending a line tech out tomorrow. I still feel like a lot of time, money, and frustration could have been saved if they sent a line tech out earlier, or set up some long term diagnostic equipment whenever there is a chronic intermittent problem.
what? I have an zero problems in wichita location issues. there are few things to ask that: did you bought the DOCSIS 3.0 cable modem yet? for long team diagnostic? there are no guaranteed speeds or latency either on the residental service. If you do have the DOCSIS 3.0 cable modem equipment installed then there's no reason for you to get tech van out since the DOCSIS 3.0 can do multiple bonded the channels into an single virtual pipeline.
I misspoke. I think he said tilt, not skew. At least that's what i think he was describing. It's a problem with the amplifier immediately upstream my pedestal.
