Dear Ronj,
Thanks for your inquiry in Quectel forum.
Could you help to check what is the Linux kernel version that you used ? And double check whether you follow up the following user guide correctly. Quectel_WCDMA<E_Linux_USB_Driver_User_Guide_V1.8.pdf (1.1 MB)
The following is the right test log, please double check it. Thanks!
If you meet the same issue, please help to confirm the following information:
1)the driver have installed successful and confirm follow up the user guide;
2)you can try to add the APN parameters to have a try again;
3)whether the module AT command response normally, if yes, please make sure whether the module attach the network successful, and must check the return value of command AT+QCFG=“usbnet”;
4)please confirm the Linux kernel version.

I got a question, while driver load successfully, ifconfig wwan0 will down or up?
because my wwan0 is down

ronj thanks for your information.
in my cdc-wdm.c
wdm_probe() // is already false
{
…
rv = wdm_create(intf, ep, maxcom, &wdm_manage_power, false);
}
usb_cdc_wdm_register() // this place is true, I will try to change this value to test
{
rv = wdm_create(intf, ep, bufsize, manage_power, true);
}
Thanks ronj
This mothod can work for me.
But I got another issue, busybox can get ip address . I will try to fix it.
