hi,
sorry for the delay. if i should move this to another list by now,
please just tell me ;)
here is my modemmanager debug log with configuration 3, mbim:
https://paste.fedoraproject.org/286797/40415144/
the modemmanager actually does see the cdc-wdm modem and connect, wwan0
does get an ip via dhcp, but i cannot ping anything.
here is the modemmanager debug log with configuration 1, qmi;
https://paste.fedoraproject.org/286803/41498144/
and yes, after stopping modemmanager, i looked if there is any remaining
process accessing the device with lsof, but nothing came up.
cheers,
muri

> All the driver info now looks good to me. Yes, qmicli or mbimcli should work. I cannot explain why they don't. Which could mean that there is something we don't see... Do you have any other processes opening the /dev/cdc-wdm0 devices? lsof is a good way to find out. Could you run ModemManager with --debug? Maybe it will tell us more about the problem.
