I installed the firmware also i installed Luci. I went to Interface and i find "LAN", "WAN" and "WAN6".
I plugged my sim to the router sim card slot. The question how to configure it?
I clicked on edit "WAN" interface. I had the bellow:
config interface 'wan' option proto '3g' option device '/dev/ttyUSB0' option service 'evdo' option apn 'APN-ADAATCS' option ipv6 'auto'
I don't know if the device is correct but i had to choose this because of my option ifname was before 'usb0'
This modem come with a sim card slot. I don't have password for APN or nothing. But it seems it is not connecting.
