Repeated loss of connectivity -- continued.

A few months ago I posted a note here about repeated loss of internet connectivity...link below...the issue still continues, so thought I would share a quick update and ask other folks how their similar issues have been resolved so we can put heads together on resolution.

  • Summary: I see frequent drops/day in internet connectivity, disrupting video calls and gaming. It's infuriating when it happens. Have had 2 tech visits, each confirming the basics (good signal coming into house, no stray connections/splitters, etc.)
  • The issue rarely perks up during 'download' viewing (YouTube/NetFlix/etc.) as those services handle connectivity disruption far better.
  • Have swapped out routers and modems, no changes. Just talking wired connection here too, no wireless.  

What's new: latest tech visit was last week, who was great to work with. After verifying signals and secure connections, he sent a ticket over to 'maintenance', which is Xfinity's network engineering team. The techs who visit our houses primarily handle from house to street, then the maintenance teams handle the network further upstream. During an internet chat with xfinity CSR, they confirmed that the T3 line coming into the neighborhood had been seeing timeouts, could be that I am downstream from these. My neighbors also experience internet hiccups, we're in a high tech neighborhood full of video meetings and all kinds of WFH information worker situations. So this means additional load on upstream channels, which is Xfinity's business to manage. I just want a reliable & stable internet connection.

So while I'm awaiting outcome from the maintenance ticket, certainly open to tools/techniques for how to monitor internet connection further stream from me. Even if it's comparing time stamps on hiccups with whoever monitors the network traffic.

Thanks for listening!

My primary issue details and logs are described here:

Weekend update

* 9 hiccups yesterday, disrupting 2 phone calls yesterday. 'Always-on' network reliability is abysmal. 

* No word yet from Xfinity tech on ticket update from network engineering investigating potential T3/T4 timeouts.

* Stumbled upon a workaround, which may or may not work for some folks: use your phone & mobile carrier as a temporary hotspot for your computer comms/gaming. Reliant upon your signal connection and data plan of course. And could use Xfinity wifi if that's in range for you as well.

Same Issues here. I have been dealing with this for a year now. Tech have been checking on the neighborhood, they have been saying the issue is on the house, then outside the house, then outside the neighborhood.

I also change Modem with upgraded firmware and we are is still going down. Sometimes is many times a day, some days are good. BUT SERVICE IS UNRELIABLE.

Last tech that was in the house check and say the house installation was good. They charge me $100 and the issue did not go away. I spent hours with Support on the phone and chat. I never got the $100 refunded. Never got my issue fixed.

Ckervien: may be we are next door....

Now looking for other alternative providers in Boca Raton. I think the issue is that the Xfinity installation is very old, cables under my garden have more than 40 years and it seem they are not willing to update or do any work. They just send inexperience techs to look around and patch things, change connectors and splitters but no real upgrades to the installation.

@Patrick_2190​ I'm in the Seattle area, so...almost next door. :) 

My current thinking is that the root cause of internet disruptions is greater upload traffic from the neighborhood is causing time-outs on area T3/T4 lines, Xfinity is trying hard to build out their infrastructure to keep up, and lacks assorted processes & timetables to keep customers and support staff informed. All of the support and tech staff have been mostly great to work with, the issues just aren't getting resolved. 

Also wish there was a better tool than modem logs that could record & timestamp specific outage moments so tech teams can compare with network time-outs. Would be happy to run one here to help troubleshoot!

I am facing similar issues for the past couple of weeks too. Mine gets lost connection for 1-5 minutes in about 20-30 minutes. I talked to a CSR through chat and he is just telling me to make an appointment with their technician and offer me a higher speed plan. I also tried to change a modem, factory reset my router and even cables. None of the regular solutions worked. I am in the Fort Lauderdale area.

So I am glad that I found this post before the technician visit. I thought they might not be able to help and charge me $100 for nothing and wasting my time. 

Awaiting solutions and considering another provider.

Hi, I am located in (edit) and I've been experiencing network drops for four years.  As I read the comments above I have had all those experiences too.  In one year I had 22  technicians come to my house.  They all did the same thing.  They cut all my connectors, put new ones on, tested the levels and said everything was fine.  But the problem is intermittent and sometimes 5 minutes later I'd experience another drop in connectivity.  They have replaced the underground wire to the house, the amplifier at my house, and every connector.  I have purchased all new cable modems and routers and laptops.   I even had them install all their own equipment for a month (I paid them to install their equipment so they would stop blaming me.) The problem persisted and continues to persist.  Last November I purchased a monitoring software and bought a laptop dedicated to monitor the Xfinity network. The software pings 3 high availability servers every 5 seconds.  Google, Level3 and Cloudflare.  When the network is up my pings are typically 15-28ms.  But intermittently they exceed 200ms and turn red.  Then the software quickly checks the other two servers.  When all 3 of the servers are unreachable everything goes red and the software logs the date and time of the outage, the duration of the outage, and also logs the local LAN connection to my router.  By the way, this is all hard wired (no wifi to blame).   The software is called NetUptimeMonitor.com.  You can see their website at https://netuptimemonitor.com/.  It is only available for a PC.  Which prompted me to purchase a dedicated PC laptop from Costco (I'm a MAC guy) to solely run this software. 

FEBRUARY 2022 TO DATE

2/13/22 39 Service Drops
2/12/22 25 Service Drops
2/11/22 30 Service Drops
2/10/22 26 Service Drops
2/9/22 6 Service Drops
2/8/22 3 Service Drops
2/7/22 12 Service Drops
2/6/22 1 Service Drop
2/5/22 2 Service Drops
2/4/22 13 Service Drops
2/3/22 4 Service Drops
2/2/22 2 Service Drops
2/1/22 11 Service Drops

The above are just a sampling of just this month, February to date.

This is what the monitor looks like when all three of the Internet pings fail as well as if your internal connection to the router has failed.  My internal doesn't ever fail so my LAN connection is always a green checkbox but everyone of the logged failures  is marked with a big red, "Internet failure!" and X:

The logs of all the outages look like this:
I keep logging tickets and technicians come out and continue to treat the problem as if it is my problem. I have bought and replaced EVERYTHING to the tune of thousands of dollars.  Because it is an intermittent problem, techs will put a meter on the demarcation location and say it looks fine and want to close the ticket.  Five minutes after they leave the dropouts continue.  It is intermittent!
I have had limited temporary help from a bucket truck engineer who found a defective underground cable a year ago (that helped a little) and this year bad amplifier upstream that was throwing very hot signals that were overdriving a pole amplifier downstream.  Some of these help a little but they are not getting to the root of the problem.  The repairs they are making are like temporary bandaids to owning the problem and really fixing it.  Hell, if they give me the amplifiers, I'd do it myself.  (I'm a broadcast engineer and software engineer by trade.) 
I understand they bought an old Time Warner network but they haven't replaced all of the legacy amplifiers so we are victims of the "weakest link" problem.
Each time I open a case I request a Comcast employee.  They send me a contractor who I understand gets paid $35/call.  They want to finish and close as many tickets as they can.  Sometimes they will involve their manager who has to do gymnastics and even lie to Comcast's Engineering group just for them to send a bucket truck (the people that are employees that can investigate the amplifiers.) The bucket guys can help and can give you hope but it is spotty.  One will attempt a fix only to have it affected by another bad amplifier upstream.  It's like wack-a-mole.  The process continues over and over and over again.
I am at my wits end.  All I want is for the internet to be stable.  I work from home and so does my wife.  Yesterday she and I were on our AT&T phone hotspots because the internet was down.  My wife was on a 4 hour zoom call having to use our hotspots because she would start on Xfinity and get dropped.  She would fire up her AT&T hotspot and log in again.  Now she has tried switching back when Xfinity comes back but Xfinity drops again so she has to stay on her Hotspot for the whole call.  By the way we had to increase our AT&T data plan so we could have additional data for the Hotspot functionality.  Ahhhhh very frustrating.
So I continue to open tickets, log the failures, get charged for the service calls (because the tech closes the tickets), I spend hours calling back for a credit because the issue continues.
Yesterday I signed up for Century Link DSL.  I have to see if I can get something that is stable.  I plan to use both for a month and see if I can get along with a slower speed.  We'll see.
I have talked with 3 neighbors that have Xfinity and they all experience the same service interruptions that my family does.  They've reported it before but they get tired and are accepting this because they don't know what else to do.  There are two Century Link customers (the local phone/DSL company) that claim that their internet service is rock solid.  I'll see.  They are getting 16mps down and 7.9mps up.  That is quite a bit slower than the gig I'm supposed to be getting from Xfinity but they claim that it is at least stable.
Anyway, if we don't speak up, they will think it is all working well.  Well it isn't and I don't know what else to do.

@ktrachy753​ Righto...thank you for all that detail and link to UpTime Monitor...just installed it. Wasn't aware of legacy amplifier usage within the infrastructure, and you've given me new avenues to explore. Next tech visit is this afternoon, as it appears the last visit didn't actually file a ticket with maintenance.

Coincidentally, Verizon started advertising their 5G home service recently, which may or may not be an option for folks depending on their location.

I've looked into Starlink, T-Mobile's 5G Home offering and Verizon's wireless but all are not available yet.  Century Link has some relationship with Quantum Fiber but that too is not available either.  All I want is for it to work.  I am even fine with finding a radio relay option if necessary. I'll run both Century Link and Xfinity side by side with network monitoring.  This is getting $$$$$. The statistics from google show more stability with DSL.  https://www.google.com/get/videoqualityreport/?v=epqYft12nV4

If anyone has any ideas, please post.

Thanks,

Kirk

I am thankful for your efforts and can only hope that this is resolved.  Is there a reason my post is marked "Private"?

Had a tech visit yesterday, let me share quick summary of that and a couple of tips to help with future tech visits...

* First...all of the techs have been great to work with...thank you. Xfinity's process for upstream troubleshooting is for customers to work with the tech, then the tech files tickets & follow-up for maintenance/network engineering team on issues further upstream.

* Tech has to confirm no issues with local signal/connections/etc. Realize this may be repetitive for those on repeat visits, but it's protocol and ensures there's nothing local happening. Tech also has ability to measure signals strength at house, as well as neighborhood utilization, which is the phrase used to describe how much network capacity is being used by local neighborhood. Some areas are worse than others right now, each area is different, it's not an issue for me currently.

* Realizing we're dealing some kind of upstream issue, we started a monitoring plan, which is essentially a log of when a hiccup happens - just capture the timestamp - then we'll hand the log over to network engineering who can take a closer at their logs and correlate to narrow down options. Unfortunately in my case, there is not an obvious "smoking gun" root case -- animal nest in an amplifier, blown out fuse, whatever. Also noted that my overall neighborhood is impacted, it's not just my house. Maintenance team really needs a log of events to follow-up with, as their typical monitoring toolbox isn't showing anything obvious.

* Couple of methods to establish a log here -- both are Windows/PC based -- so Mac folks will have to figure out their own.

1) Pull up a DOS prompt -- type CMD in the Windows search bar -- then use a PING command at the DOS prompt, which will fire off a quick hit to another web site every couple of seconds, where the main goal is wait/watch for a time out. In our case, we're using google.com like this: "ping google.com -t".

2) The NetUptime Monitor mentioned earlier in this thread is even handier with a nice interface, and automatically creates a log on outages. It's free to use for about an hour each time, unlimited number of uses, and you'll have pay a few bucks for a permanent license to get past the usage time limit. Handy tool, good find!

3) I've already logged a hiccup moment, so the documentation process is underway.

* So we'll take a week establishing a log, pass along, and keep at it. The issue has been super frustrating for me, so glad to finally get traction on this.

@ckerwien​ Hi, glad to hear they are doing something. What does your hiccup moment say on the ping notes?

@mingjuan_2​ The hiccup will appear as a time out on it's own line when I use the PING command. And if you're using the free app mentioned earlier, you get an obvious message and automatic log event registered in a text file. Right now I'm keep just a list in Excel, 3 events logged so far.

The xfinity Community Mailer just emailed a reminder to me to "accept a solution" on this thread, which of course doesn't exist yet, so thought I would post a quick update.

* We are currently logging hiccup moments with a time stamp. I've had 5 over the past few days, which is significantly less than prior to the tech visit earlier this week.

* One item I forgot to mention during the tech visit -- which may or may not be significant -- he replaced the wall mount where the cable modem connects to the wall via the coax. Hard to say if this is significant, but it's frequently an overlooked item and I rarely see this mentioned in any online message. Even putting aside the obvious "is it a tight secure connection?" verification, the mounts work via screw-on compression to create a tight seal around the signal wire, and perhaps may have worked loose if it's been off and on a lot while troubleshooting issues. So if you're coming from a place of leave-no-stone-unturned, give that a look too, you never know.
