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:

I'm having the same problem , I'm in Bothell WA, so at night or weekends upstream is much better.

Had two technician visits but with no luck, they mentioned it is a network overload/congestion and they need to upgrade the node that our neighborhood connects to but it needs a managerial approval !!!

meanwhile customer service is denying any issue 😞

 

Frontier provides internet in my area but it has the worst customer service as well.

I think the issue is across a few services in WA/OR.  I think my signal hit a new low tonight.

@trackrat2 Wow, I had the exact same thing happen tonight and I live in Vancouver as well. As of right now, I'm down to about 2% PL but I had easily 20-25% for about a solid hour or two. It was completely unusable even to stream video, let alone something that required a constant steady connection.

 

I also have a scheduled maintenance in my area slated for 1:00 AM on Wednesday. Wild.

I've been having lag issues with games since very early February. Maybe it's true that some people's lag really is just from the extra people staying at home. It's probably not though.

Texas btw, wishing more than anything I can distract myself with the whole staying at home thing with a game of League that doesn't lag.

Same issue here in Chicago (zipcode 60634). I have tried everything and talked to at least 5-6 Comcast employees. Two technicians came by and they said everything looks OK. The Customer Service has no clue half the time and simply follow a script / guide.

I am using my 4G tethering through USB to be able to play video games on my desktop. The lag and rubber-banding with Xfinity is beyond believe!

Also, got a response on my Washington state attorney general complaint.  It's going to the next steps for the informal consumer complaint process.   I will withdraw it if the issue is resolved of course but in the meantime, at least it's being reviewed.

Good idea on switching to your cell.  I did that for a bit yesterday-amazing that it was better than my wired cable internet connection.  Iracing is my main PC hobby-it's not that high on data use but a stable connection is really important.

This morning was the worst performance in the am I have seen-not terrible but maybe its because I was slightly later than usual in my test.  Either way, still seeing large spikes.  I believe Comcast has techs still working on the issue as there is another service outage notice for tomorrow.  This morning and tonight's pings attached.

Service seems relatively stable right now but Outages and Maintenance the last couple days continues. According to the status center, it'll be resolved at 9:33 AM this morning.

well looks like they expanded the outage to 5pm PT so they must still be troubleshooting-my ping looks pretty rough right now.

TraceRT to Comcast has lots of timeouts but I assume that could be due to maintenance in progress.

Well guys I gave up. Months of awful spikes with no real acknowledgement or solution from comcast. I signed up with the company that took over Frontiers fiber and my comcast internet is ending this month. Good luck to you all.

@Gorgon12345 Don't blame you. I'd go to Ziply in a heartbeat if it was available in my area. With any luck, they'll expand their service territory and I can finally drop Comcast.

I have not done as exhaustive a test of my setup, but it sure sounds like I am facing similar issues. When I run Speedtest, I get the following:
Local (Seattle) servers: ping = 8, DL = 85 Mbps, UL = 6 Mbps (typical and expected results)
Comcast (Richmond, VA): ping = 85, DL = 26, UL = 6
Moscow, Russia: ping = 200, DL = 15, UL = 6 (I tutor online with Russian students)

 

The only numbers way out of whack are the download numbers. Until roughly mid-March, all speedtest results were very close.
I also ran traceroute and ping, and cannot find anything to explain this. After 200 iterations to a Russian server, no packet loss.
Now here is where I need technical advice: I have rebooted using the cable modem's config page, rebooted from the XFinity website and ran speedtest when the modem is freshly turned on. None made a difference.
Today, a tech over there at Xfinity did what she called "provisioning", which completely fixed the issue UNTIL she hung up. THen, it was back to where it had been.
What is provisioning? How can I do it myself?

You wrote: "I would think it's the same as resetting your modem." FWIW, no. It's not. Resetting does not change / re-enter the backend account data in their database. That has to be entered manually by a rep.
