Hello, I've had great service for the past few months until 12/3/17 (Sunday)
where my upload speed has dropped to between 2-5mbps, which is definitely not
what I'm paying for. My download speed has been completlely fine, but my upload
took a massive toll for no apparent reason.
First, I tried contacting online support who tried to do something from their
side, but nothing worked so they scheduled a technician appointment for me.
A technician came by today and replaced the modem, checked outside lines, etc.
He said everything was fine at my house and there was nothing wrong here.
Still, the issue has not been resolved and I'm very frustrated because I do
live streaming and it's impossible to stream with this low upload when the
kbps drops all the way down to zero every 10-15 seconds.
New modem - Technicolor MTA Model: TC8717T

I've checked other forum posts and none of them have been any use. I'm not
running any cloud services, dropbox, etc. I haven't changed/downloaded anything
ever since this problem has happened.
I am on Wired / Ethernet connection.
Not sure what logs are required for this type of situation, but here are some:

All of your incoming DS levels are borderline too high, especially DS Chnl 2 reads over 12.6 dBmV, where the max allowed is +10.0. Inserting a 6 dB pad will bring things down, but your outbound US levels will not tolerate the 6 dB loss in that direction.
You can have the home service tech inspect your drop cable and replace if it is chafed by a tree branch or gnawed on by squirrels. Same if you have an Internet service only "No-TV" filter somewhere in your feed. Water leaking in anywhere along the drop cable or into the filter is a BAD thing!
Actually those DS line levels are far enough out of balance that a line maintenance crew should come out to recalibrate the upstream line amplifiers. That in itself could improve both internet and TV for the entire neighborhood.
Yes, my download levels are completely fine though.
The technician already came and said everything with my cables were fine outside and inside.
Why do you insist that your signal levels are OK? The window for DS (incoming) channels is -10.0 to +10.0 dBmV. Did your service tech show you what the DS levels are on each of the incoming channels? And what does your modem show after the tech left?
I see that all of your downstream signal levels are out of the range they should be.
I also see high uncorrectables on all of the upstream channels.
