Hi,

I have a RM520N-GLAP and I need the latest Windows PCIe drivers.

Firmware: RM520NGLAPR01A03M4G

Can you please provide the drivers to me?

Hello,

I have installed this driver and so far it works, but…in the Windows 11 device manager one instance is highlighted to have a problem with error code 31 - driver cannot be loaded which annoys me.

Affected device: “Quectel 5GNrCoexMgr Modem Device” , HW ID {7DCB3244-C836-4A0C-A1E9-BD68D385AA2B}{d2d6990d-2bec-4736-8369-df2fc6e85257}

Any idea how to resolve this?

Could you show the device manager and the errors?

Well actually I tried this latest driver, but it does not solve the problem at all. Even worse…now all UDE Com Ports (AT, NMEA etc. ) have disappeared which means no more access via AT commands, e.g. to obtain GPS data.
Tried to go back to the old driver but it does not help. PLEASE help…seems like the new driver has changed the adapter configuration.

Out of interest: Should the PCIe drivers create anyway a modem device entry in the device manager? If so this would also be required to resolve…
