EM7430 drivers not working correctly on Dell Precision 3571 Windows 11

Hi, I have installed the latest driver for the EM7430 on my Dell Precision 3571 running Windows 11. I am having issues with the user interface of windows under the cellular settings e.g. when I click to turn cellular data on it does nothing.

Do you have modem port to check AT command setting?
e.g.
at+cfun=1
at+cfun?
at!pcinfo?
at!usbcomp?
ati3

Seems currently you are using RMNET, does it work for MBIM?

I have installed the card inside my laptop and not sure how to check the AT command.

you can check whether you have the modem port for AT command communication in device manager.

If no, see here on how to get back the serial ports

yes it is there

Please check AT command setting
e.g.
AT!entercnd=“A710”
at+cfun=1
at+cfun?
at!pcinfo?
at!usbcomp?
ati3

does it work for newer FW?

how do I know what one to pick from the 7430 list?
Telstra and Generic give me this.

are you using the driver of GenericDriverSetup_5087.exe

I am thinking if this is due to two RMNET enumerated in your environment.
you can try

AT!ENTERCND=“A710”
at!usbcomp=1,1,10d
AT!RESET

I’ve installed the driver 5087

I am thinking if this is due to two RMNET enumerated in your environment.
you can try

AT!ENTERCND=“A710”
at!usbcomp=1,1,10d
AT!RESET

worked with 100d.

Thankyou

Hi,
Just to precise :

Effectively, it works like this:

AT!ENTERCND=“A710”
at!usbcomp=1,1,100d
AT!RESET

Don’t forget to install the 5087 driver with the parameter USBCOMP=8 to get access to the modem.
