High Ping and packet loss

Hoping for some help as I have been unable to get any help from Xfinity recently-chat/bot only wants to reset gateway which doesn't solve my issue.  Have been on hold several times but unable to get through to a tech.

 

currently on 175MPS plan.  Have a new Arris SB6183 with a Asus AX-88u router.  Wired connection to gaming PC-have tried both direct from modem and from router-still have high PL %-spikes of 30% wtih either connection.  no splitter instead the house wiring-have swapped the cat 5e cable-no difference.

 

have had the issue with high packet loss the last couple of months.  had a tech come out and he did find a signal loss-replaced a connection outside the home.  internet was better for a few days but now back to high ping, etc.  

Have ran ping plotter to gaming server, google, and direct to modem.  Modem plot is fine.  showing PL loss from 2nd hop to final hop for google, iracing.com servers and twitter.  Latency has large spreads.  Have tried different PC with similar results.

 

Here's the modem report:

The longer I let ping plot run, the worse it gets....frustrating.

Another afternoon of rough internet.  Typical performance and no resolution yet.  Attached modem specs again-no real change.  I am still thinking that it is outside my system since 5am to 9am PT (sometimes later depending on the day) doesn't have any loss.

Same issue here along the shoreline in CT. I’ve been having this infuriating issue since March. Called Comcast and had a tech come out who did nothing. Ran his diagnostic and said all look good, but told him otherwise.

I created a quick script that parsed my ping’s time. Out of 767 entries, 460 were greater than 100ms when pinging google.com.

How do we get help from Comcast? They truly need to get into contact with us folks. I’ve done everything possible on my end.

This is most definitely Comcast infrastructure/service related. Too many people having exactly the same issues. As others I've done everything that I can from talking to reps and doing what they told me to try to trying different hardware (router, modem). I also had a tech come out and check the line but I am not sure if they actually check for ping, latency and packet drop or just check signal strength and noise. Also, it's VERY possible that the tech came out and tested the line when the service condition was good.

 

Download speed (files, streaming videos and even speedtest) is mostly fine because you wouldn't notice small drops here because of buffer but apps that require continuous and instantaneous data download/upload (online meetings, gaming, video chats) will display significant issues.

 

By the way, Comcast did the service maintenance in my area a couple of weeks go but nothing has changed since then so don't get your hopes up although do report back if it improves anything.

Jumping in to add the list of people with terrible packet loss/ping during work hours without issues during off peak hours.  It's particularly bad around 3-5PM. I'm in NorCal with 1000Mbps plan and am unable to game at all. Even loading websites takes forever. 

 

This is on a wired connection.

Just wanna say, you're doing gods work here. I live in Vancouver, WA and get the same issues. Last week's maintenance in my neighborhood made it a little more manageable, but I still frequently get periods like this https://imgur.com/a/9cxLOWF that make it nearly impossible to attend a video conference during the day or game at night.

 

I can't recall how many times I've been on chat or phone about the issue, but it's starting to get real, real old.

I filed a complaint with our local cable commission. That prompted a response from a corporate comcast representative:

 

I understand your frustration when service slows down due to capacity issues.  Our residential services are built for entertainment purposes and as most Americans, Comcast was not expecting a large population to start working from home.  As you are aware, we all are in uncharted territory with this National healthcare issue.  We are working towards a resolution to this issue.  Please let me know if you have additional questions or concerns.

 

Thank you for your time,

In other words, until the virus situation is resolved, we're all going to have poor service. Yet comcast continues to market and sell more and more services that require access to an already overloaded system.

@splurce - Thanks for forwarding that to us. I've been checking this thread frequently. 

 

At this point, it does not seem like anything is going to get resolved. Yet, like you mentioned, more and more users seem to be added to an infrastructure that really doesn't seem to be able to handle the load. I understand, it's a rough time for familes and professionals alike. But, we are paying customers. I don't know..

Thanks for posting.  That is more or less the response I have received on my complaints, posts, etc. on Twitter and other chats.

 agree we are paying customers and should have a stable connection at least....If I am going to get roughly 15% Packet loss or so, my bill should be adjusted accordingly or Comcast should take my/our "investment" and make the needed enhancements to Handle the traffic.  Top Speed isn't as important as stability and reasonable latency. 

 

I expect internet traffic will stay in high demand as companies/schools are changing their approach to work from home, learn from home, etc..  Need a solution for the long term. Comcast is fooling themselves if they think the bandwidth saturation and demand is going to drastically drop off.

I went ahead and filed a complaint with the Washington State Attorney General as well.  Since I am not getting any meanful/helpful response from Comcast.  Will continue to document -encourage others to do the same.  Once again, early am, internet works great-

Aargh-feel your pain there.  It's a bit better for me this afternoon.  Not as good as this morning but considerably better than most days.

Bump-here's today's signal-typical afternoon PL.

Guessing there is a little more traffic due to Mother's Day.

Doesn't make this okay-still need increased bandwidth in Portland/Vancouver-not just because of Covid-19 increased traffic....

Daily bump-great internet this morning-I expect about 3 hours of this.  Wish I could move all my web activities to 6am but that just isn't realistic-my bill is due=I will pay but not in a hurry.

It looks Comcast fixed the issue last week in my area after 2 months of bad Internet
So far so good after 1 week of usage.
