Windows 10 em9191 pcei m.2 adapter

Issue we’re experiencing. Using a mini pcie adapter to a m.2 adapter, we are able to get the em9191 to connect to a 5G network, using a tmobile sims card. However, we are experiencing a random drop from the modem and occasionally on reboot of the windows 10 server the modem doesn’t show up at all and we have to reinstall the driver to get it to work again.

What other information can I provide to help here?

suggestions? We are going to try updating the firmware again.

Is there any problem with a linux PC?
(Or you can install virtual machine with linux image to verify)
