      Hi

      we are trying to set up the 5G quectel modem, we tried with different mobile networks and different SIM cards.
      We are getting a disconnection from the mobile network approximately every minute, sometimes a bit more.

      Looking into the journalctl we can see the following pattern every few seconds: carrier lost and the modem connects again
      We are thinking if the config-wwan0.sh could be the reason... but any other ideas are appreciated

        @nacho I'm seeing references to modallink-relink, that shouldn't be used in your configuration. I would run through voxl-configure-modem again and make sure you answer "no" to "Are you attempting to connect to ModalLink?".

        Or you can disable it with systemctl disable modallink-relink and a reboot.

            Hi @tom !
            Thank you for your response, the issue was solved by deactivating this service.

            Thank you so much
