So I recently upgraded my internet speed from 100 mbps to 1200 mbps. I got the new modem and set it up. I tested the spend and the download is pretty good! But the upload is almost the same as my previous speed. I called customer support and they said that was unacceptable and that I should be getting at least 30! So they’re sending me a new modem that’s brand new. Will this really help? If not, how can I get better upload? I need it for what I’m trying to do and I’m getting very frustrated.
