Upload Speed incredibly slow

Hi,

I just typed up this message in full detail, but upon signing in it erased each field. Forgive me for my brevity. 

Yesterday afternoon my upload speed slowed to a crawl for unknown reasons.
I have the 400 Mbps plan with up to 10 Mbps upload. I pay for no data caps. I have the XB6-A modem. 
I changed nothing about my network physically or in the settings. I did not acquire any new devices and connect them.

My network is operational/online, and my download speed and ping are normal.

My upload speed is so slow that video calling or playing live video games is not possible, but download-only activities like watching YouTube videos and downloading files works as expected.

I spoke with Xfinity chat in-app support and got little help. They offered to send a new modem and tried to upsell me a faster speed and a cell service add-on, both of which I declined. No further help or an offer to escalate my issue was offered. 

I don't see how the modem can be the issue if my network is still operational. If the modem was broken, how could just my upload speed by affected?
I have not had any issues like this in 13 months of service up until yesterday. 

I did all the basic troubleshooting techniques. I restarted my modem multiple times, reseated cables, tested on multiple devices both wired and wireless, tested on multiple websites. It's all the same: 0.01-0.10 Mbps upload speed. 

Please help.

I am also experiencing the same and have the same setup/plan. I believe they have reduced the upload speeds when prior I was receiving 50mbps+ of Upload.

Please create a new topic of your own here on this board detailing your issue. Thanks. 


For future reference, it is better to submit your own new / separate post as it creates a ticket to get help, and posting on someone else's thread can delay getting help.
