I updated yesterday to SWI9X50C_01.11.00.00.

Is it enough to switch it to qmi mode and to use the command from above?

Is it independent of normal linux/openwrt? Should I check both?

OT: I have some trouble with that device at the moment. Under linux it runs only in qmi-mode well and under Windows in mbim-mode.

Thomas
