I live in the Silverado Ranch area and it just went *** up tonight at 7:50 pm. I know this, because I've had pingplotter pinging cox.com for days and at 7:50 pm I started getting massive packet loss. Modem has a plethora of T3 errors. Checked my neighbors modem and his is screwed too. Garbage infrastructure that they refuse to upgrade, because they have a monopoly on broadband.
BTW I'm in the NE near Lamb and Centennial. and exactly, *** monopoly leaves no other options. My final test is to TRY their panoramic router, just to document it. I'm expecting the same issue. Tuesday I had 3 techs at my house trying to fix it, replacing wiring in my ceiling and documenting ingress from the street. clearly a COX issue and not my house.
The only way an Ingress test is going to be helpful is if the problem is happening right then...like right now what's going on down here, but they'll show up in a few days when the intermittent issues are gone and see no problem.
I can tell you right now there is probably nothing wrong with your modem. Check your modem levels and event log. Ideally, your downstream power levels should be right at 0db and within a 3db window. Upstream should be in the high 40's and within 1.5-3db of each other. If the range varies for either of those, you'll get Dynamic Range Window errors. SNR should be around 40
T3 errors are super common and are usually caused by noisey lines...which falls back to their junk infrastructure which could be their street taps, cabling, or just a faulty modem card in the CMTS.
They'll of course come out and swap your F-Type connectors a million times leading you to believe it's YOUR infrastructure, but it's not. It's their junk.
You couldn't be more right about those *** F-type connectors, I told them the previous tech already replaced them a week earlier and they did it anyways... I'll check the event log thanks for the suggestion.
