Dear Aleksander,
perhaps an interesting observation. I could connect through the
Network-manager. I restarted the Modem-Manager and the Network-Manager service.
After this I could connect with the nm-applet gui. Also I could connect with
the nmcli d c cdc-wdm0, but only after I restarted both mm and nm.
Kind regards,
Thomas

Betreff: AW: MC7455 not working
Dear Aleksander,
I have been following the discussion on the mail-list. 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.
I’m looking forward for an answer.
Kind regards,
Thomas

That is perfect now.

Not all DHCP clients work with the raw-ip interfaces. IIIRC the
openwrt dhcp client does work. But that's why ModemManager explicitly
states the static IP config, if you set that config, you won't need a
DHCP client (if you use NetworkManager as well, all that will be
automatically done for you).

Yes, yes, forgot to explicitly mention that to you. The first official
release with the new raw-ip support is 4.5, although there are some
previous rc versions which already have it.
