I have a system with 4G LTE modem.
I am currently using ncm protocol to connect to 4G network.
It works fine.
But sometime for some reason the system present a message log like that
Thu Apr 4 17:45:53 2019 daemon.notice netifd: Interface 'wan_4' has link connectivity loss Thu Apr 4 17:45:53 2019 daemon.notice netifd: Interface 'wan_6' has link connectivity loss Thu Apr 4 17:45:53 2019 daemon.notice netifd: wan_4 (5767): udhcpc: received SIGTERM
After this kind of messages, the ip address of the 4G interface disappeared and I have no access to internet. Which is quite normal.
But I am wondering about the fact that netifd is not retring to connect to the 4G network.
I need to do a "ifup ethLTE" to reteive a 4G network connection and obviously an IP address.
Probably it is an issue in my configuration.
I used that one
config interface 'wan' option ifname 'ethLTE' option proto 'ncm' option device '/dev/ttyModem4g2' option mode 'lte' option delay '3' option apn 'orange' option pincode 'xxxx'
How can I do to have permanent retry of connection to the 4G interface when I have a loss of connection?
