Alternatively you can also set the modem to MBIM mode and use luci-proto-mbim (for that you need kmod-usb-net-cdc-mbim installed as well as umbim). ModemManager supports MBIM modems. I am not sure of the reason for 10d vs 50d. One point to note is that the world has started to move more towards MBIM as a standard interface across all OS/devices because Win10 natively supports it now, it is on a par with QMI in terms of functionality and there is an open source Linux client, which again is getting up to the same standard as the QMI one. MBIM - For use with modem manager etc with the open source drivers. Should we use MBIM because it is faster or QMI because I see lower pings?
