T-Mobile Home dropping Internet

I too have the same issue as a matter of fact the internet dropped 10 minutes before the ball dropped on New Years Eve and again each night since at around 10pm My home device sits on a windowsill and I live in the northeast if anything it is almost cool to the touch. I find it odd that it drops out in the evening even though I use my internet all hours of the day. I love the cost saving but should this continue I will have to go back to the devil I knew
