Bufferbloat to the max with 1.2gbps down and 35mbps up - XB8-T
I am extremely desperate right now-- this is a cry for help 😭. Xfinity says they're not doing any network improvements and nothing is down in my area. I think it's easier to show the types of 'spikes' in latency I see through my internet connection:
I'd love to seek any help possible from any strangers that are out there that could help. Here's the things I've tried:
- Restarting gateway tons of times
- I had a tech out here run a few speed tests through the modem and he said the 'speed is fine' and that 'nothing was wrong with the Xfinity connectivity' based on the signals. I think he was purely operating for down and up speeds.
- Confirmed that I experience this through a laptop (wireless) and desktop PC (wired) directly connected through a gateway. Both environments receive D/F grades.
- Also tried cat 5e, 6, 7, 8 cables. Still nothing to help buffering issues.
- Tried tweaking different configs via https://www.speedguide.net/articles/windows-1011-tcp-ip-tweaks-5077 . Nothing is helping.
- All DNS testing resulted in higher latency times (per the screenshot) via https://dnsspeedtest.online/. Busy times (8PM) or non-busy times (2AM) testing yielded no difference.
The DNS testing and the laptop/desktop testing really tells me there's a single point of failure somewhere, I just don't know where. I'm truly at a loss and can no longer bear the issue. My family still loves our connection because they can still stream 🤦. Is there anything else I can test or try to improve my bufferbloat?

Not entirely sure what went wrong today but have another appointment setup tomorrow. Appointment was cancelled today for no reason. Tech said they were at my location without attempt to call me.
Will follow up when I find out more.

UPDATE:
The 2nd tech visit has determined there was lots of noise levels coming from my coaxial cable to outside of my house, then the tech performed other tests outside. There might be something wrong with the “tap” — I believe this refers to the outside line to Xfinity lines.
Not entirely sure if I can post the support ticket here as it pertains to my issue. Is there any way I can view the tech’s ticket out to Xfinity and the status of it based on the number?

UPDATE:
Xfinity came to work on probably the network of cables outside my house or where ever my network of houses sends traffic to (most likely last night -- I experienced an outage).
you can see the DNS latency massively improved. Also, the buffer/jitter are nearly gone:
I'll run some test later tonight to see what the congestion looks like. Hoping that these problems are resolved:
