Hi Aleksander, I used Arch Build System to grab the existing package builds of libqmi and ModemManager and built 1.14 and 1.5.990 respectively from https://www.freedesktop.org/software/. I still got similar output using kernel 4.4.5.
I then tried installing linux-mainline which on Arch is kernel 4.5. After running simple-connect, I noticed "mmcli -b 0" indicated the wwp0s29f7u5i8 interface and an IPv4 configuration of dhcp with IP address, gateway, etc. I could not get a dhcp client to work, but manually setting an address with "ip addr" and doing a ping through the interface with "ping -i wwp0s29f7u5i8 8.8.8.8" did yield results. Is this the correct behavior? >From googling around I found this: https://mail.gnome.org/archives/networkmanager-list/2015-December/msg00042.html I guess this means that MC7455 will only work in kernel 4.5 due to better raw-ip support?
