T3 Timeouts

Hello,

I've had my comcast business intener for about 4 months now and I've had nothing but intermitten connectivity issues from the start. I'm a Twitch Partner (I stream video games/ content) my career requires a ton of upload usage. I have 220 download and 24 upload, any time I stream from my PC which is plugged in via ethernet cable my internet goes down for about 60 secs then comes back on. The modem lights remain on and flashing as if nothing is wrong. But my streaming software (OBS) indicates that the internet is going down and I start to drop frames. Comcast put in a order to replace a cable line outside my home on 9/30/2020 and they finished the job yesterday 10/1/2020. I was called after the job was done and tried to stream. As suspected 5 mins into my stream and the internet in my home went out. I've tried everything at this point I bought a new PC, my modem was replaced, the line was replaced outside and I'm still having connection issues.

This issue is affecting my business and my children's e learning from home. I have logs up to 90 days showing the same T3 timeout. Any help would be greatly appreciated!
