Hey thanks I didn't realize I could do that. Updated the article with the docsis log. Bunch of UCD invalid or channel unusable and SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing
gotta ask, just because i went through this with spectrum recently. have you grabbed an extension cord and tried connecting the modem outside at the drop for awhile? i hear you that your neighbor has the same issue. but if youre in. say a development by the same builder, or were all part of a comcast upgrade at roughly the same time .. and well… you both recently upgraded to 1.2(?) because that would be the latter ca…
This seems pretty likely, but shouldn't a tech roll have included sampling the signal strength/snr at these frequencies? Or would the tech tools be likely to be on old frequencies too?

I had an old 15+ year old line when I moved in. Helped my neighbor cut a few hundred of his monthly by getting xfinity and they ran a brand new drop for him. Then just recently they "upgraded" my line. But I don't have any splitter or filter its just a connector with a ground that attaches my home cable to the drop cable.

#54If OP is reading this, try downgrading to a Docsis 3.0 modem. Docsis 3.1 in Comcast’s deployed infrastructure has severe repeating outage issues when there’s a cracked line somewhere allowing RF leakage into it, that cause a partial 3.1 reset but have no effect on 3.0.
i touched on this in a longer comment in this thread because i think that docsis 3.0
goes up to 900-1002mhz
if downgrading to docsis 3.0 (or downgrading to 500/700mb) “fixed” your issue, you probably have a 5-1000mhz splitter thats not just a rf splitter but also, a filter and its JUST leaky enough to allow 1002mhz through.
or maybe the modems happy negotiating down to 900mhz.
but maybe not quite enough for 1008-1100+ required by docsis 3.1
there will be anecdotal reports of a 5-1000mhz splitter “working just fine” maybe that ones a REALLY leaky filter thats also allowing 1008mhz.
or also a case of negotiating a lower channel…
gigabit speed and docsis 3.0 are about the threshold for the 5-1000mhz
problems would manifest with docsis 3.1, gigabit speed(maybe) and then almost guaranteed at 1.2 gig service+
this idea of “sensitive channels” is extremely close to nailing it
splitters fail as well. they’ll bleed through AND filter bands theyre not supposed to. but i didnt seize on that or inside wiring for OP because “the neighbor gets it too”
im on a gigabit implementation that has to have +/- 1100mhz , and my own woes uncovered an 800mhz splitter inside a wallplate. it would lock. it would even run at gig somehow. just not very well. its a 5-2500mhz splitter now. a 5-1200mhz would also do (for now)
everyone on your tap should be using multiplexed signals, and you should have a good 300mhz or so to play with and lock onto. but if every single one of you gets kneecapped at +/- 1000mhz, then theres a really congested 100mhz band and another 100-200mhz thats open for everyone but you cant lock on to it.

#55When you need a company like that to do something, figure out what they're afraid of.
The only thing monopolies like these are afraid of is the government. So if you want them to get off their asses yesterday, raise a stink with whatever arm of your government will listen: FCC, local politicians, etc.
You would not believe how fast even the lowest level government workers can get these guys to take care of your problem with a single phone call.
Re: A monopoly ISP refuses to fix upstream infrastructure
#56I had this same daily connection disruption problem with Xfinity on the east coast, on two different lines in the same building.
But, one difference is that the two lines would fail at different times, not at the exact same time (so not the cause guessed by Gemini, in my case).
I always assumed it was Comcast automating downtime to prevent anyone using the lines for business without paying Comcast Business prices.
I had the two locations connected by fiber and used multi WAN for both load balancing and failover, so the combined uptime was basically 100% because each line was down many times per day, but they were always down at different, non-overlapping times.
My guess is that this failure mode is quite common, whether or not it's intentional. I would love to see this be something a lot of us here can coordinate on jointly pushing Comcast to solve!

#57Couldn't cell or Starlink substitute in this day and age? 5G cells are pretty prolific now. So even if you might not want to actually leave, it's a perfectly good threat and functions as competition in their eyes.

the SNR and the lock would be perfect at the drop using tech meter.
or, plugging your modem into your dmarc/outside box for a little bit would also confirm or deny this

Amazing that we now live in a world where AI can instantly an accurately diagnose a network infrastructure problem, but you are still forced to talk to CS drones who tell you again and again "have you tried unplugging it and plugging it back in?"
I'm not so sure that's an accurate diagnosis. But I agree it's certainly better than one can get from phoning support.
I can't speak to the accuracy of the diagnosis, but the claims about NTP are bizarre, and to the best of my knowledge, wrong. There's nothing specific about the times the incidents cluster around that would have anything to do with NTP. It doesn't work like that.

#60My cable internet was down for 3 weeks after a maintenance, they sent out someone 2 times. We had an irc channel where engineers from most of the countrys isps were in, but not this isp, but then i remember that there was a guy consulting for them. Took him 5 minutes to fix it, it was a problem with my speed profile (increased upload plan) and I was the only one in my area that was on it.
