5G Home internet keeps dropping!

The problem may or may not be with the gateway. You will have to contact T-Mobile support and ask about the work on the equipment in the area. They could be working on the equipment for the cells in the area so it would be a tower problem. From what you can see the internet connection is not available therefore the cellular connection is a highly probable source of the problem.

One thing you can look at are notifications the gateway may have recorded so check for notifications via the LED screen. Another thing to try would be to power the gateway off and remove and reinsert the SIM card. If there is a problem with the SIM card, which some Arcadyan gateways seem to have, then this might help if it is related. That is why I would suggest to check the notifications for errors related to the SIM card. Reseating the SIM card will not hurt. If you have a T-Mobile phone and both tend to use the same cellular source that might be another clue. If your phone transitions to another cell when the gateway drops its cellular signal then it could be a tower equipment related problem. T-Mobile engineers might be performing work on the equipment in the area. T-Mobile does not appear to provide any customer notifications regarding work being performed on the equipment.
