Since I installed the USB version of the Quectel_LTE & 5G_Windows_USB_Driver_V2.1 driver, i am loss of cellular network in Windows 10 settings.
If I uninstall the driver, cellular network reappears in the windows 10 settings (network and internet).
If still cannot solve your issue, it is better to change another PC to have a try. We also use such driver in Win10 PC, have not meet such issue. Thanks!
I did a test on another machine and the problem and the same. I think the problem comes from the bluetooth module associated with the AC-7260 WIFI. I put you some Windows event recordings.
