5G modem keeps losing 5G

My 5G modem (arcadyan) keeps randomly losing 5G connection. It happens randomly and once or twice a month. When it loses 5G, it switches to 4G which works but is obviously slower. There are cases where 4G also slows downs to a few kb/s. The only solution is to unplug and restart. Another problem is that I have my own router connected through Ethernet. I don't use the T-Mobile modem wifi. Whenever I restart the modem, 5G won't come up if the Ethernet cable is plugged. The only way to get 5G is to restart the modem with Ethernet unplugged and connect Ethernet once the modem locked on 5G. Sounds like bad firmware on that modem. Am I the only one experiencing this ? Obviously T-Mobile customer service has no clue. The only thing they suggest is to restart the modem. 

   I had the similar problem with the older black gateways. We now got the brand new Arcadian G4AR gateways/router. This new router from T-mobile has now never went off line for over 2 months now. Plus this new router has more wifi transmitting power by a fair amount. Take your old gateway to a T-Mobile store and exchange routers for the brand new white gateways G4AR.  If the store gives you grief about exchanging it. You can always stop your home internet for 5 minutes and then start a new home internet device over again. My store near me exchanged without issues. But friend only got the brand new white gateways by turning in his old router. Then went to next store a few miles away and got the brand new design router.  Hope this makes sense and helps.  Good luck
