RM520N-GL Shows connected from AT port, not passing connection to Win 11

Hi,

We are configuring two RM520N-GL modems connected via pcie under windows 11.

The modem has been configured with APN and Password.
The modem shows as registered / connected and has an IP address through the AT port.
An mbn profile with the APN and credentials has been added to the modem.
In windows the Quectel Wireless Ethernet Adapter is not showing as connected or having an IP address assigned. When manually connecting from windows it displays ‘can’t connect to this network Enter an APN and try again.’

What is the recommended way to configure the modem with an apn username and password when using via pcie in windows 11?

After reinstalling the drivers one modem is able to connect in windows. The other will not showing. ‘can’t connect to this network Enter an APN and try again.’

Are there any commands that be used to configure the windows driver?

Is there a different command that should be used other than AT$QCPDPP?
I can’t find any around setting the credentials and auth type in the AT command manual Quectel_RG50xQRM5xxQ_Series_AT_Commands_Manual_V1.2.

Commands Issued to configure modem
AT+CGDCONT=1,“IP”,“APN”
AT$QCPDPP=1,2,pass,user
AT+CGACT=1,1
AT+CGPADDR shows the expected ip address

Dear @RyanCorvanta
You had inserted the module to the PC, right?
Please share with us that how the module connect with PC.

Yes the modems are plugged into the motherboard M.2 slot
The modem Wireless ethernet adapters and ports like AT and NMEA are showing in windows

Dear @RyanCorvanta
It seems you need to install PCIe driver on your PC, but this driver should be implement by your PC vendor.

Through device manager the modems are plugged into a USB v3 hub.
This should be supported by the standard driver?
Currently using NDIS v2.3 are they the recommended drivers for windows 11?
