WARNING!!! Aug 8, 2024 - Potential Flaws in G4AR 5G Gateway Firmware Update v1.00.09 Related to External Antenna Use

Sep 9, 2024 - New G4AR Firmware Update to V1.00.12 from V1.00.09 Today!
Now I am really confused.  My G4AR Gateway was updated to firmware version v1.00.12 from v1.00.09 today.  The G4AR display and T-Mobile Internet app now no longer show an internet connection to 5G, ONLY 4G!!!  However, the 4G download and upload speeds now seem to be about the same as the former 5G speeds.  The former 4G speeds were unusably slow.  So, am I really connected to 5G???  I have yet to see if any internet disconnects from v1.00.12 occur so far, but I am watching closely.  The Aug 13 message confirming "payment of my internet bill" still came up again when the gateway was restarted.  I will see if that Aug 13 message was really "dismissed" this time the next time I restart the gateway.  What other new problems will there be with this new firmware version v1.00.12???   Do I still need to switch to "interna" antenna first before restarting the gateway?  I will be finding out soon!
