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?

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?

does it work for newer FW?
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.
