nils-anders, I investigated a little more and discovered that the modem
is non-functional when TLP is installed. Are you perhaps using TLP? If
so, that's the likely culprit. If not, there may also be other kernel
modules interfering. Check in
/lib/modules/4.4.0-36-generic/updates/dkms/ and see.
Clearly this setup is not ready for prime time. Too many things are
broken.
