5G Home Internet T-Mobile Gateway needs to be fixed. There are too many internet disconnections.

Let me start by saying I do like having wireless internet. The problem is I don't think it is ready for primetime. Speed is great, price is great, but It loses its connection to the internet about once every two days. It's sad. I have spoken with T-Mobile many times. They have updated my firmware and done other things (I have no idea what they change there), and they tell me that these changes will fix all the problems. Sure! I am getting close to asking them to replace my Gateway to see if that helps. Has anyone had a replacement and found that helped?
