unacceptable performance!

All day everyday!

This is my service performance all day every single day, as I have noted with the desktop packet transfer picture, this router is sending and receiving data from 5g tower to my desktop tower, all the time, then it records this packet transfer as service usage. However it is not actually providing any internet whatsoever ever between 10AM - 8PM. It's not just a coincidence that those happen to be T-Mobile business hours either. There is a network throttle order in place, this is something I experience like clockwork, every single day with this service. I get a couple hours at night of decent service and that's it. EXPLAIN T-MOBILE!
