I have not been here long, but I am already building and flashing images to my TL-MR3420v2! OpenWRT rocks!
I am trying to get WAN working through an MA260 USB 3G stick using the QMI interface, as using standard USB-Serial seems to want to fail. Here is where I am at:
1) Build image containing the "usb-modeswitch" and the USB serial modules and QMI etc.
2) Connect USB stick and the log shows me I have 3x ttyUSBx devices and a "cdc-wdm0" and "wwan0" with a MAC address
3) Configure an interface in "/etc/config/network" like so:
config interface 'mobile' option proto 'qmi' option device '/dev/cdc-wdm0' option apn 'general.t-mobile.uk'
4) Reload the network config
Am I being totally stupid? I am really struggling to find any more resource on this and I really need this to work for the project I am working on. Any help would be great!
