3G Modem MC8805:qmicli succesfuly connected but no IP after dhclient

Tue Oct 27 07:32:30 PDT 2015

lsof /dev/cdc-wdm0 responde is blank
I took a look on dmesg but cdc_mbim was just after the qmi_wwan but to 
be sure I add "blacklist cdc_mbim" in my /etc/modprobe.d/blacklist.conf
now I notice I got a wwan0 interface (before it was something like 
|wwp0s20u7c2i12

dmesg is saying :
|dmesg | grep usb
