I found that a configured wwan interface will stop working after a few days. I suspect that ISP just want to assign us a new dynamic ip. To make it working again, I need to disconnect and reconnect wwan0 interface, so, I believe we should add `shutdown_required` when running the command `connect interface wwan0` Steps to reproduce: 1. set interface down and up ``` sudo ip link set dev wwan0 down sudo ip link set dev wwan0 up ``` 2. Run ping check (it will failed) ``` ping 1.1.1.1 interface wwan0 ``` 3. Re-connect wwan0 ``` sudo mmcli --modem 0 --simple-disconnect sudo mmcli --modem 0 --simple-connect="apn=internet" ``` 4. Run ping check (it will work now) ``` ping 1.1.1.1 interface wwan0 ``` However, I found that cron script is also using command `connect interface wwan0`. So just adding `shutdown_required` will cause cron script to restart too often.
