Sprint Aircard 341U modem issue

[dailijin]

Hi All,


I encounter a strange issue about Aircard 341U modem based on kernel 4.4.0 kernel, the modem can get IP 192.168.1.4, but ping network always fail. no care use qmi_wwan or GobiNet driver.


Is there anyone encounter similar issue?


Below is my log.
