Anyone that has switched to a static IP hub with 5G SA support noticed that the Cellular Network Technology won't save the 5G SA config? I have gone thru 2 FX4100 and they have the same issue. When the modem reboots, the 5G stays but the mode switches to NSA, thus modem not making network connection. I can manually switch it to SA and connection will go up. Next time I reboot the modem, it goes back to the same cycle. The only way I can make it work is to set it to Auto 4G/5G NSA. When it reboots, it will connect to the slower 4G/5G hybrid mode, then I manually change it to SA and get the full speed. TMO support confirms this is not a bug in the modem but the FX4100 will only support NSA mode upon startup when it detects static IP configuration and revert to NSA regardless of saved config.

I was also told the new FX4200 supports full 5G SA configuration. Has anyone been able to get an upgrade to the FX4200?

Has anyone with static IP noticed the speed and latency going down progressively after switching to a 5G SA hub? My latency increased significantly and speed was slightly higher in the beginning. Recently, I have noticed that performance is progressively going down but my signal strength has not changed. Can it be because more people are jamming into the 5G SA hub or my local tower is just becoming more congested?
