What is the status of your WWAN card? ONLINE, LOW POWER MODE or something else?

 

It is possible your device is not properly initialized. Can you post Legacy_Sierra_QMI.kext that you are using? Info inside must match your device.


If your device is in ONLINE mode send PPP log, so we can try to figure out what is wrong.

 

If your device is in LOW POWER MODE, you can try to bring it to ONLINE mode. Check BIOS and try with WiFi keyboard switch like would you do in Windows (FN + button with WiFi icon).
