I’m trying to get network-manager working with a MC7455. I upgraded the kernel to 4.6.2. I updated the libqmi (1.14.2), MomdemManager (1.5.992) and NetworkManager (1.2.0) to the latest versions. The modemmanager can use the qmi interface. I can connect with the mmcli to the network. I can receive an ip address with udhcpc -I command. The problem I still have I can’t get the Network-Manager to start the connection. I have read the mail below that states the NetworkManager will config the connection for you. It seems that the dhcp set-up from the NetworkManager fails, see trace below. Now my question what can I do to get the network-manager to set-up the connection.</span><o:p></o:p></h1> <h1><span lang="EN-GB" style="font-size:11.0pt;font-weight:normal">I’m looking forward for an
