Hi, I'm trying to use a Novatel EU850D 3G modem in a Cambria board (GW2358-4) but the network interface is never set up after configuring it properly. Using the same configuration with a Sierra Wireless MC870 works.
I have installed the required kernel modules (usb-serial-wwan and usb-serial-option) for the system to recognize the Novatel module and map the corresponding usb devices for the data and control channels (ttyUSB0 and ttyUSB1 respectively for this module), but when trying to set up the interface through a 'ifup interface_name' command the output of the /etc/ppp logfile is chat: Mar 27 03:48:44 CONNECT HSDPA 7.2 Serial connection established. Using interface 3g-wan Connect: 3g-wan <--> /dev/ttyUSB0 Hangup (SIGHUP) Modem hangup Connection terminated. So my question is, has anybody successfully configured and set up a Novatel EU850D 3G module in any Gateworks board (also tried in GW2380 and getting the same results)? Do you have any idea about what could I check/configure to make it work? Any help would be really appreciated. Thank you, Javier
