5G Home internet keeps dropping!

For what it's worth, I've had the newer SAG FAST5688W gateway for about 2 months now and it is having the same drop issues, so I would doubt the issue is with the various gateways. The longest connection sustained so far has been a little over 2 days, and the worst has been multiple reboots per day. That said, when the service connects, I do usually get over 50Mb throughput (it's using the N71 band). Being in rural Virginia, this is great for us. 

To help make the constant rebooting less aggravating, I did see in another thread a device called Keep Connect - $50 on Amazon. Installed it yesterday and it has already automatically rebooted the device once, so now I don't have to manually intervene. We'll see - gateway has now been up 16h 38m 19s.

It's unfortunate that T-Mobile can't/won't fix their software to do what the Keep Connect device does - automatically detect connection failure and restore it. Funny how you never have to reboot your phone.
