"Plug'n play" or did you do some kind of configuration? I've recently have some problems on make this modem work in ofono, but if the modem can work it would be nice. > I am having trouble with configuring which internet connection the system > has to use. > In particular I would like the BBB use the internet connection via LAN if > the internet via LAN is up, else the other connection (via usb internet > key). > I have configured the two eth connections with different priorities > (/etc/network/interfaces), however if the LAN has no internet connection > the system don't use the usb-key. > I post my config file. > > eth0 = wired connection, gateway 192.168.0.1 > eth1 = via usb internet key, gateway 192.168.1.1 > > I believe Debian default network connection manager is Wicd, I never used. I'm currently using Connman to manage connections and default route.
