upload speeds drop ridiculous low! - Time Warner Internet

This question is about "upload speeds drop ridiculous low!", with Time Warner Cable internet and apps. i have a 300mbps plan and my usual upload is 22-25mbps well recently it has been .8-1.5mbps. just switched modems completely and it helped for the 1st day of the new modem now they are back to being low. all signals are good according to the phone rep. any reason why this would happen my download speeds are great! its just my upload which i need since i am a internet content creator and this has hindered me from streaming.
