I am using a mc7455 in MBIM mode on a LEDE build using modem manager. QUESTION #1
i am getting these errors 10 min after a reboot. Im also having multiple disconnects where it becomes unregistered. A ifup broadband will take care of reconnecting it but after a few hours ifup broadband no longer works and a reboot is needed.
