Poor upload speeds to most if not all servers.

Here recently I have attempted to fix an issue regarding streaming to Twitch and problems with my upload speeds. 

I have gigablast and have amazing download speeds, but when it comes to my upload speeds I suffer tremendously. Having a tech come out tomorrow for the second time to take a look at my lines just to make sure but last time everything was perfect. 

I don't know what information to give here so I'm going to just go ahead and list off a bunch of different things in hopes maybe someone knows what's going on.

I'm running the modem provided XB6t

On another note they told me this modem supports gigablast but the thing is getting super hot and my speeds are jumping all over the place. On top of that I'm reading a lot about how it's not suppose to be for anything of these speeds?
