Hello Aleksander,
Thank you for directing me to the NetworkManager mailing list. Here is my situation. I want to use NetworkManager to create a 3G connection using ModemManager and the qmi_wann driver. libqmi 1.16.0 mmcli 1.6.4 nmcli 1.0.12 I have had success issuing the commands below along with other commands using mmcli and qmicli. qmicli -d /dev/cdc-wdm0 --wds-start-network=apn='apn=mnet.bell.ca.ioe' --client-no-release-cid mmcli -m 0 mmcli -m 0 --simple-connect="apn=mnet.bell.ca.ioe" I think the problem lies with NetworkManager: root@raspberrypi3:/# nmcli con show NAME UUID TYPE DEVICE Wired connection 1 bdc6b7b3-1e60-453c-bfca-11ce7519826d 802-3-ethernet eth0 cellular bd4fbd79-329c-4af2-a68d-a330df553abd gsm -- root@raspberrypi3:/# cellular was created with: nmcli connection add type gsm con-name cellular ifname wwan0 apn mnet.bell.ca.ioe But my wwan0 interface shows “unmanaged” and I cannot bring it up: root@raspberrypi3:/# nmcli con up cellular ifname wwan0 Error: device 'wwan0' not compatible with connection 'cellular'. root@raspberrypi3:/# root@raspberrypi3:/# nmcli device status DEVICE TYPE STATE CONNECTION eth0 ethernet connected Wired connection 1 lo loopback unmanaged -- wwan0 wwan unmanaged -- The newly created cellular connection appears in system-connections: root@raspberrypi3:/etc/NetworkManager/system-connections# ls cellular root@raspberrypi3:/etc/NetworkManager/system-connections# Interesting, the eth0 Wired connection 1 is not shown in that directory, nor can I find a definition for it. An interfaces file does not exist. root@raspberrypi3:/# find . -iname "interfaces" root@raspberrypi3:/# If you are available to assist I would appreciate hearing back from you. Many thanks! - Phil
