years of packetloss and dozens of techs cant fix it

testing verizon hotspot on my cell phone...zero packetloss, it's your move comcast, are you going to fix your network or keep blaming my equipment?  this was with an ancient samsung galaxy s3 that wont do more than 3mb down and 3mb up.   worlds cleaner than my 1gigabit/40 HARDWIRED comcast connection.

by the way comcast it's also costing me money to use my cell phone as a hot spot so if at any point you want to fullfill the multitude of promises to reduce our bill, go for it because I dont think this is worth full price for years:

graph from right now on 1 gigabit cable from xfinity/comcast...would anyone pay for this?

If you need Internet for work, or other important reasons, I would go with DSL, or possibly Space X (Satellite) service.

testing with my 10 year old cell phone samsung s3 (verizon) tethered to my pc and gamed for over an hour and only lost 3 packets the whole time for comparison today.

Ping statistics for 1.1.1.1:
    Packets: Sent = 4336, Received = 4333, Lost = 3 (0% loss),

my son received a text instead of me for some reason...it's actually worse after this;

Late to the thread but is there a comment in here that describes the equipment (Cable Modem Model) and or QOS paid for? 

  "Packet loss" happens all the time and usually the internet device along the way compensate for that and the effects are transparent for the user.. 

Further what packet sniffer produce the graphs above? Does tracing to a particular Ip address similarly drop traffic? Timeout?

  Lastly, isn't the IP address dynamic?  Quick trace to comcast.net shows 69.252.80.** with 25.668ms latency.. 

Just my .2 cents. 

Thanks and good luck

tech should be here in a few hours and I'll be leaving this screen up LIVE for them to watch while they work.  This will be the 3rd tech this month, I sincerely hope comcast sends out someone that's interested in finding the source of the problem (comcast/xfinity network) instead of focusing on the final destination (inside my house)

Tech just came and replaced that same splitter again (4 way splitter is now a 2 way again), captured some data on his device and said he uploaded that to someone for review.  He said he's escalating the issue to maintenance because the tap at the street isn't getting enough signal.   At least someone agrees with me finally that it's not my house and they are wasting time inside.  He left a piece of paper with a ticket number and his name...I've never seen this form before, I guess the other techs weren't doing that as it has a survey on it.

Here's what it looks like currently

being told a tech is coming on the 5th of January...and their policy doesn't allow for refunds until it's fixed (it's been broken for at least 4 years), how convenient

Glad that progress appears being made. Its interesting the tech apparently acknowledged the distribution point street side isn't getting "enough signal"

 Hopefully this isn't silly question but is any other users there off the same tap or substation experiencing similar packet loss, signal issues?

Sounds like if that's the case, you may be getting closer to root cause of the trouble. Hope things work out and your back online soonest.

 Just my .2 cents.

 Thanks and good luck.

The tap at the street has two connections and both show the same problem.  Several previous techs have come and swapped the connection with my neighbor and I had the same packetloss issues.  I've gotten this far many times before and this is where it's escalated to "maintenance" otherwise known as the black hole.  The problem is that it takes so much time to get to the bottom of it that sometimes this issue will go away for a day, a week or even a month on it's own between visits and comcast will close the ticket.  They will not know what fixed it because they had nothing to do with it.  The problems always comes back and I have to repeat this whole process over and over again with 1st level cable splitter jockeys that tell me the decibel levels are good and dip out.   There's just no accountability with the local subcontractors...the guy that came today was yet again a subcontractor.  You'd think by now I'd get someone from corporate IT down here to investigate and start holding them accountable for their failures in a meaningful way that helps the customers in my area.

These local subcontractors don't realize they are trying to bamboozle a network/computer systems engineer so it's quite comical the litany of excuses they give me before they leave sometimes.  They will look me dead in the eyes and lie straight to my face when they know darn well it's not fixed.  I can only imagine what the people around me are dealing with that don't have the technical prowess to call comcast/xfinity out or at least speak the language of IT.   If the techs don't know what they are doing and the customer don't know what they are doing, nothing changes.

My next steps will be to start canvassing the neighborhood(s) to find out the extent of the issues going on here.  I can very easily bring my laptop and show them what's going on with their own connection and explain why their movies are a pixelated mess, disconnects etc...  I have zero doubt a small claims judge would make short work of comcast in the local court, they hate big corporations that screw the little guys.   A 10k fine per customer is chump change for comcast so its not going to change their ways or fix their network.   This will require the FCC and a class action lawsuit to truly get their attention at higher levels...big profits are the only concern for monopolistic corporations.   I'm up for the fight if they want to keep screwing us over.  It'll be their mistake to make if they want to keep ignoring the crux of the problem and handing out placebo pills.

We already moved to a neighboring city 45 minutes away to get away from these issues two years ago...everything in this area goes to the same first node so it made zero difference.  It sure would have been nice if back in the day when the government paid telcos 400 billion to upgrade the country's infrastructure to fiber instead of pocketing the cash and doing nothing.  https://www.reddit.com/r/explainlikeimfive/comments/6c5e97/eli5_how_were_isps_able_to_pocket_the_200_billion/

just a DOS ping test to get a quick view of whether or not I can use my internet for my purposes today...that's a big nope :(    Back to the Verizon cell phone tethering we go

I bought two verizon wifi hot spots for the house, I can't afford to wait on comcasts "maintenance department" to get here and I have zero confidence in them anyway based on history.  I'm literally going to have to pay two ISP to get work done which burns up my income.

current situation with comcast;

4 years of this comcast, can you be bothered to hurry up?  we're really sick and tired of being disconnecting in the middle of games, movies  and work...we are bleeding cash over this!
