Jitter and Bufferbloat problem

Hello,

I would like to report ongoing internet stability issues with my Xfinity connection.

Although the download and upload speeds appear normal, I am experiencing significant jitter, latency spikes, and bufferbloat, especially during gaming and real-time applications. When running bufferbloat and latency tests, the connection shows instability and inconsistent performance.

The issue affects:

  • Online gaming

  • Voice communication

  • Streaming stability

  • General network responsiveness

I have already tested multiple devices and connections, and the problem appears to be related to the network quality rather than device performance.

I would appreciate it if this issue could be escalated to a technician or network specialist to check:

  • Signal quality

  • Node congestion

  • Upstream latency

  • Packet loss/jitter

  • Bufferbloat under load

Thank you for your assistance.

Jitter is 39.2 and it should be below 5 ms. Average latency should be below 20 ms. The connection is unstable and I’m experiencing dropouts. I can’t do anything with this internet. Please take action and fix the internet connection.

What do the modem's signal status values look like ? Try getting them here; http://192.168.100.1 or here http://10.0.0.1 


Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.


What is the exact make and model number of the modem / gateway device ?

Is this with a WiFi connection ?
