Home Internet Gateway Needs Reboot Multiple Times Daily, Internet Access Dropping

I'm experiencing the same issue as others here.  Got the service in January.  Worked perfectly for a month or two.  Then the trash can (Nokia 5G Gateway N1) started needing to be reset on a weekly basis.  Then a couple times a week.  Now daily...Recently multiple times a day.  Signal always comes back immediately upon reset (reset takes 2-3 minutes).  If not home, no ability to reset device which makes Nest thermostat/cameras inaccessible.

I keep my device in my 2nd story window facing where I believe cell tower is (info online for 5G towers is sparse).  Also have the window covered to avoid direct sun/overheating.  Have tried with and without secondary routers connected.  Have tried plugging device directly into outlet, connecting to a surge protector, and connecting to an APS Backup-UPS.  Makes no difference, signal still drops.  Time of droppage is sporadic, but I have noticed an increased frequency shortly after 5pm which I find curious.  If I had to guess, the issue is a software glitch when the device switches between primary and secondary towers.

The current frequency of dropping signal will unfortunately force my wife and I to switch back to a more stable internet provider if cannot resolve (both working remotely and attending frequent video calls).

I called T-Mobile today to try to request the new device that others have mentioned, but was instead told that there were cell towers being serviced in the area over the last few days and the issue should be now resolved [eyes rolling].  This of course would not explain why the issue has been occurring for months on end…

They will be following up in a few days so I will report back how that conversation goes.  Seems like they issue new devices only as a last resort so unfortunately the only way to get one is to keep complaining again and again.
