5G Home internet keeps dropping!

The cellular wireless 5G solution is not a simple solution that will work for everyone. Transmitting through the airwaves will always have challenges. A fixed wired solution that is a mature technology is going to be more reliable. Maybe one day cellular technology will evolve to be a more stable and robust delivery system but it does have a way to go yet. 
I think it is important to remember that the objective cellular vendors have is to reduce overhead costs and boost the revenue returns for investors. In some markets the solution is working but but as expected not for ALL users. If they focus primarily on the bottom line and don't attend to the problems it will continue to be inferior. End to end details make great companies. Execution does matter.
