5G Home internet keeps dropping!

I have had the same problem. Good reliability for the first month or so and then started dropping out for an hour or two at a time. A week or so ago it dropped out and did not return. We were gone for the last month or so with our motor home. I'd call tech support and all they could offer was to rest the gateway which obviously I couldn't do when not home, We returned home a couple of days ago and I promptly called Cox to reinstate our internet service, I then called T-mobile to cancel my internet with them. They asked why and I explained that I needed reliable service for my thermostats, security cameras, etc when we are traveling. After I said that they said no problem and proceeded to process the cancellation and sent me a return label for the gateway. The fact that they made no effort to convince me to stay makes me believe that they know their service is unreliable and there is nothing they can do about it.
