I have made a minicom-runscript script to set up internet using the modem: ac100modem
just apt-get install minicom, configure as "minicom -s". After that you can run ac100modem as root to get internet access.
You can then type Control-A Q to terminate minicom while staying online.
This is a very light-weight way of managing the network. You can even kill wpa_supplicant. And dhclient (I get a 24 hour lease).
