Hi Piotr,

I'm testing latest LEDE trunk snapshot (kernel 4.9) for ZBT WE826 with a MPCIE Quectel EC25 module.

When I install all QMI stuff (enumerated by wildy), /dev/cdc-wdm0 shows up automatically and after interface configuration this is the best I get from QMI:

With UMTS/GPRS/EV-DO protocol everything works just fine.
