[RESOLVED] Xfinity slowing download speeds again? Why?

Xfinity slowing download speeds again? This is crazy. Within 3 days, the download speed cut in half. Why? I'm not changing anything.

Well, it has been over 24 hours since I posted this message. I was hoping for some response by an Xfinity forum monitor (which I know there are) to address the situation. The spreadsheet doesn't lie. As of today, the speed tests still showing a significant downgrade.

I don't know if the solution was that I rebooted the Xfinity router or Xfinity cleared up something overnight or this morning. Now download speeds are back to expected levels.

@user_zwe4nj Thank you for reaching out to us about your speeds. How are you running speed test? What are you noticing on your devices. We do recommend running speed test from our site https://speedtest.xfinity.com. In addition to this I am glad for this to be finally working, power cycling could have sent through any needed updates.

This morning I made a slight change in my first floor home office configuration. I moved the gateway one foot closer to the my home office's door that leads into the living room. Everything in my second floor home office remained the same. The Pod, the 1Gbps switch, the cabling into the switch and between the pod. All the same. Ran the Xfinity speed test from each laptop (a mix of Windows 11, Ubuntu, and LMDE), to include the VMs running on them. I'm getting >300Mbps of download speed. Really solved now...
