Nightly Internet Speed Drops Despite 2100 Mbps Plan starting around 7/8pm PST

Hello Xfinity Support,

I’m requesting help with a recurring internet speed issue.

I currently pay for a 2100 Mbps download internet plan. During the day, my speeds are generally close to what I expect from the plan. However, starting around 7:00 PM each night, my download speed drops dramatically, often maxing out around 50 Mbps.

This appears to be a recurring evening issue rather than a general equipment or plan problem, since speeds are much better during the day. I would like this investigated as a possible neighborhood congestion, signal, provisioning, or service-level issue.

Details:

• Plan speed: 2100 Mbps download
• Daytime speed: Close to expected plan speed
• Nighttime speed: Around 50 Mbps max
• Approximate start time: Around 7:00 PM/8:00 PM PST nightly
• Issue frequency: Recurring in the evening

Please check the signal levels, local node utilization/congestion, modem provisioning, and any service issues in my area. I would also like to know whether this issue can be escalated to a network technician if the problem is not visible from basic troubleshooting.

Thank you.
