Network starting error in Quectel EC25-J .

[Mashkur Ahmad]

Hi Aleksaner,
 Thank you very much for your support.

 At first i want to share some more info it might help to understand the
issues.
 I use raspberry pi :  Linux raspberrypi 4.14.79-v7+ #1159 SMP Sun Nov 4
17:50:20 GMT 2018 armv7l GNU/Linux.

sudo qmicli -d /dev/cdc-wdm0  --wds-set-autoconnect-settings=disabled
[08 Feb 2019, 09:52:31] -Warning ** [/dev/cdc-wdm0] requested auto mode but
no MBIM QMUX support available
Autoconnect settings updated

 sudo qmicli -d /dev/cdc-wdm0 --wds-start-network=apn='isp.docomoiot.net
',ip-type=4,autoconnect=yes
[08 Feb 2019, 09:52:49] -Warning ** [/dev/cdc-wdm0] requested auto mode but
no MBIM QMUX support available
[/dev/cdc-wdm0] Network started
        Packet data handle: '2266172864'

I called above command and now i am able to start the network successfully
but i am not getting the ip in wwan0 interface.
i have also applied  'sudo dhclient -d -4 wwan0' command but not getting
ip,

By checking the status i am able to see the network ip
 sudo qmicli -d /dev/cdc-wdm0 --wds-get-current-settings
