Suddenly slow home internet.

When I first subscribed to the home internet service in April the speeds were pretty good, 65-70 Mb download and upload speeds. By July I was lucky to get 40-45 Mb. I cut the cable a number of years ago and decided this summer to invest in a 4K TV, AV receiver and the 4K apple TV. The last few days have seen my internet slow to less than 5 Mb/s. I'm thoroughly disgusted with T-mobile's service. When interacting with them they repeat the same BS in order to repair the speed yet nothing improves. I've considered going back to my DSL service and buying a dual WAN router to combine two separate ISP's. This is 2021. Is it too much to ask for a consistent 40 Mb? JFC, we can go to Mars.

Same start month a year later. Similar good speed tests until late December 2022. Now my four devices buffers continuously and I live in small two bedroom apartment on ground level. Less than a mile from two towers. My speed test connects with locations 20 to 50 miles away. What is with that?
