Only seeing DM/NMEA ports

Technical Subjects Driver

Do I need a specific driver version (Windows 11)? This is after switching the “usbnet” to 1 to attempt using QMI.

2

Which module is it?
I guess that you have set the modem to RNDIS mode.

3

Hi it’s the RM520N-GL.

4

Which Quectel driver you have tried?
Please check
AT+QCFG=“usbnet”
AT+QCFG=“data_interface”

5

I don’t have access to AT commands anymore, as mentioned.

Last commands I ran to set the values you are asking are:

AT+QCFG="data_interface",0,0
AT+QCFG="usbnet",1

I have all three drivers installed by the way.

  • ECM 1.0
  • MBIM 1.3
  • NDIS 2.4 (tried 2.7)
  • RNDIS 1.1 (tried 1.0)
6

Please do not try the RNDIS driver.

You can use the MBIM driver and set the modem to MBIM mode with

AT+QCFG=“usbnet”,2

If you cannot send the AT on this Win11, you can try it on Ubuntu PC.

Thank you! I removed the RNDIS driver and that worked.

I have another issue now, I am trying to follow this guide to get a standalone modem working with the same SIM card as a working GLi.Net Spitz X3000 (same RM520N-GL modem).

So far I have done the following to match them up to the same parameters but the modem is not registering onto the network as AT+CEER returns EMM detached and I see +QLWURC: "deregister", 0 after a period of time.

Anything else to check?

There was a similar situation. The modem was also not registered on the network. The at+cfun=1 command helped me

I’ll try that again, thanks for your response. I also tried a factory reset AT&F, what carrier are you using?

p.s. I found a few more commands here I’ll try…

I’m from Russia, so our operators are definitely different and you haven’t even heard of him) Did this at command help you, or is registration still not going through?

I found out yesterday that the modem is working properly via the “usbnet” as I can use the connection via my laptop but it seems the “pcie/mode”/modem isn’t connecting on it’s own.

I currently have it configured as described here RM520N-GL - PCIe to Ethernet... (and DHCP!) - #7 by spacesuitdiver
