Nm. Seems the stabilty was electrical. Swapping power socket did the trick.

Please close.

Not for me, 1.03.19 is not useable. Standing in same spot with my 5g phone getting 45/10, turn on modem and connect and getting 0.200/fail....seriously???

I have had the new white 5G Gateway G4SE that T-Mobile markets with pro support. I made the mistake of switching from the previous model the F5688W which was working fine with multiple devices and multiple gaming PC’s and gaming consoles. Now, not a single console can play a quick match online for more than 30 seconds and disconnects from the server. I spoken with the so called Personal TechPro team and they could not help. I have now found a better solution! Order Starlink its on sale now! Forget about calling the Personal Tech Pro and wasting your time. They never called back. 

No do NOT close. There is 100% an issue with this update. There are huge threads on it.

Call TM Home internet tech support and 844-275-9310 to complain. Then make sure they open a ticket. Also they may send you a replacement GW. If there are enough people calling, complaining and making them do maintenance replacements maybe TM will finally hear us. I currently have the G4SE with 1.03.19 having the same disco issues and they are sending me a G4AR, which I will check fw version right away hoping it is the older version fw as I know it will work until it upgrades FW. The one thing I did catch the tech telling me is that they can lock my GW from getting fw updates pushed, which I might do with the replacement.

.Removed

This is what i was also told.  My replacement will be in on Monday
