Why is Comcast Internet UPLOAD speed so slow?

The year is almost 2021. Everyone is going online with digital devices, TV, Security Camera, video call, and remote works from home.

I ran through several issuses and slowdown for almost 3 weeks now.  I can't do any video meetings due to the SLOW UPLOAD speed 5Mbps.  The download speed is fine but the upload speed is so bad. I have to disable my security cameras whenever I have to do the remote works. THis is RIDICULOUS!!!

What is going on? Why is Comcast not increasing the upload speed espcially during CoVID-19 pandemic?
