Very slow upload speed issue (upload speed tested at 0.10Mbps)

My upload speed has dropped to abnormally low speeds.

I tested it today at 0.10Mbps. It should be over 30.0Mbps.

Dropbox files that should take a few minutes still not syncing after multiple hours.

Please advise? Please help!

Thank you!

As you can see from the screenshot of the Google speed test; less than 1/10th of 1Mbps is my current Xfinity upload speed.

Oddly, the problem is isolated to using an ethernet cable to connect to my PC.

When I unplug the ethernet cable and run the PC on wifi to same router, I then get much lower download speed, but normal (over 30Mbps) upload speeds.

Thank you for the screenshots and updates @ChewieRoRo. You stated that you're using the Google Speed test. What speeds are you getting when checking them here? Have you tried replacing the ethernet cable?

Yes, I have replaced the ethernet cable; and as I noted - it's only the upload speed that is impacted; which seems to eliminate the cable as being suspect.

Also, as noted - upload speed via wifi on the modem are fine; yet download slower.

I don't understand what has happened to my service; it's been several days now.

I can't use any software or service that depends on reasonable upload speeds.

IE, Dropbox. Or uploading to YouTube.

We are not sure if you need to replace the modem or not, @ChewieRoRo. We will get this figured out so you can use your service once again. This link shows our minimum system recommendation per speed tier, https://www.xfinity.com/support/articles/requirements-to-run-xfinity-internet-service. Is your device good for the system recommendations? Are you using an xFi Pod?

It's hardly necessary to ask that question when a customer is reporting upload speeds way below 1 Mbps. You really ought to be checking on their signal stats, since they haven't posted any here.
