I have a very strange problem with mobile internet connection (usb modem Huawei E3131). I use NetworkManager to connect and manage internet connections, modemmanager and usb_modeswitch are installed. When I connect my modem to my laptop I have PIN prompt, type it and everything is ok. When modem log in and I want to connect to my mobile network I have an error:
) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/2' failed in libnm-glib.. I found some topics posted 3 years ago and solutions posted there don't work for me. I must add that restarting ModemManager and NetworkManager services by command:
sudo systemctl restart ModemManager && sudo systemctl restart NetworkManagersolves the problem. It only helps when I restart both services at once, restarting these services separately does not solve the problem.
From journalctl -u NetworkManager (when not working)
