I’ve tried compile the openwrt 23.05 (snapshot) with modemmanager and all dependency on it. At first boot my modem is detected and connected to the internet, but the supported protocol is ppp then after reboot my modem didn’t detected by modemmanager although my modem still recognized on lsusb && lsusb -t but no cdc_mbim driver, only option.
Any solution for this problem?. My modem is Dell dw5821e (T77W968). On ROOter the modem can running without hassle
