Speed down during day even after upgrading modem

Hello,

 

About 3 weeks ago, I had asked a question on my internet speed going down during the day (both upload and download). I am on the 'performance pro' plan and I think that is advertized as up to 200 Mbps (down) and 5 Mbps (up). The speed would consistently drop to around 50 Mbps (down) and less than 1 Mbps (up)  during the daytime. I was using the Arris SB6141 modem and was recommended to upgrade it. I upgraded to Arris SB6190 modem. 

 

Now with the upgraded modem, I see speeds of 200 Mbps (down) and ~5 Mbps (up) during off-peak times like in the night and weekends. However, during weekdays day time, the speed still reduces to ~120 Mbps (down) and less than 1 Mbps (up). I am ok with with the download speed dropping , but cannot live with this upload speed . Makes working behind a VPN for official work nearly impossible with Skype calls. 

 

I had called technical support, but got an answer that not much further debugging could be done as I do not own a Xfinity gateway and have my own modem. 

 

Any suggestions on how to make sure the upload speed does not go down like this , especially since I am paying for the plan which should be at least giving me about ~5 Mbps (upload) speed.

 

Thanks
