      @tom This may be my issue, I still had the standoffs unscrewed so I could take the SIM card out easier. Which two connectors are you referring to? Will rescrew the standoffs in the meantime

        @groupo The two board to board connectors, J2, and J4 as seen here: https://docs.modalai.com/5G-Modem-datasheet/#j2-voxl-2-board-to-board

        I would also ensure that the modem card is fully seated in the M0090 add-on as well

          I tightened the standoffs back down and the wifi adapter came back on! Also, wwan0 is up for the modem now too. thanks @tom

              @tom I have a lot of modem-related trouble shooting I would like to do before coming here for actual help, but while I am going thru that, I'd like to broach our use case and see if you have any initial reservations about it. We are running a private LTE network. I know the APN and am calling voxl-config-modem accordingly, but am running into some qmi errors. While I am digging thru some of voxl-modem and voxl-modem-start to see if I can get a handle of what is going on, do you know if this use case is supported?

                @groupo The private network would have to be compatible with the flavor of modem hardware you're using but that is something other customers have done in the past so I don't see any issues with that plan

                  @groupo Are you using a Quectel or Sierra modem?

                    @tom we are using the sierra, I noted in another post that it is the 9291 and I see only an option for the 9191, but one of the other devs (Alex?) had said that the 9191 option would be fine

                      @tom I also will note, modem-flavor-wise, it is B3 LTE network (though, we are in America) which is supported in the datasheets

                        @groupo Yeah that option in voxl-configure-modem is correct, I should update it in the future to make it more clear.

                        This is what gets run on boot with that option: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/scripts/voxl-modem-start?ref_type=heads#L122

                        For that modem, voxl-modem just acts as a wrapper for qmicli: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/scripts/voxl-modem-start?ref_type=heads#L147

                        and udhcpc: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/scripts/voxl-modem-start?ref_type=heads#L160

                        Feel free to modify the script as needed to fit your application
