Dear Maintainer,

I'm using a Lenovo Thinkpad T440s with built-in LTE card "Sierra Wireless EM7345 4G LTE" (as bundled by Lenovo).

I can connect using network manager, but only when the system was not suspended (or hibernated) in-between. After suspending, I have to reboot; otherwise network manager will show an error message:

Disabling/enabling the modem using `mmcli -m [id] -{d, e}` did not resolve the issue.

I observed that `mmcli -L` shows the modem with a different ID after each suspend. Without suspending, the modem has ID 0, after suspending the first time it gets 1 (and increments with each suspend). I'm not sure whether that's expected behavior.

    mmcli -m 1 --simple-connect="allow-roaming=no,pin=1337,apn=web.vodafone.de"

I have no experiences with modem manager so far and not totally sure what's expected behavior and what's not, nor what additional information to report. I attached a debug log excerpt from the syslog of a connection attempt _after_ suspending the machine.

Using Windows, the card also works after suspending the machine, so it should not be a hardware issue.

Regards from Lake Constance, Germany,
Jens
