RM520N-GL: issue with windows drivers

I previously has installed on my Windows 11 laptop the drivers for RM520N-GL working fine. I had to uninstall them due to some conflict with the drivers for RM500U. Once finished the activity with RM500U I uninstall the related drivers and tried to install the ones for RM520N-GL. No way now I can get the modem properly recognized. This is my actual status:

I tried many things, installing the drivers in different order, rebooting the laptop every new installation/de-installation, remove driver from the system using:

pnputil /enum-drivers | findstr /i quectel
pnputil /enum-drivers | findstr /i qualcomm

pnputil /enum-drivers

pnputil /delete-driver oemXX.inf /uninstall /force

Nothing worked…

Here the drivers I am installing:

Also, even if the Quectel USB AT Port (COM4) “looks” fine, I am not able to connect via serial connection the modem.

Anyone else faced this issue? Any suggestion?

Thanks in advantage for your support.

As I guess the RM520N is boot in RNDIS mode,

You can try remove all the Quectel driver and just install the RNDIS(Q) driver.

If it still not work, we need a Linux PC.
