hi, i would like to replace my Fritzbox 6850 with OpenWRT. So i’d need a modem with 4G/LTE and Wifi 2GHZ and 5 GHz.
installation of version 25.12.0-rc2 worked well. I’ve learned: with one WifiCard only one band is possible. So i’m using two 8822CE cards in the mcpie slots (one for 2,4 GHZ, one for 5GHZ) - they are working well
for LTE connection I’ve bought a EM05G card (M.2 slot). with package “kmod-usb-net-cdc-mbim” OS recongizes the card and i was able to create an interface (MBIM and also Modemmanager) but card is not working.
Screenshot
as Modemmanager “says” “MM_MODEM_DISABLED” i tried to activate it with “mmcli -m 0 --enable” but got an error message “error: couldn’t enable the modem: ‘GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Retry: Retry: Invalid transition’”
here are some additional infos:

then i wanted to check some stuff with AT command…but how to connect? Devices show only the /dev/cdc-wdm0, but there is no tty/usb device Package “kmod-usb-serial-qualcomm” is installed, what am i doing wrong?
and also a bit strange: i was able to switch to SimSlot 2 once, but now, when trying to switch back (mmcli -m 0 --set-primary-sim-slot=1) i get also an error: error: couldn’t request primary SIM switch: ‘GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Timeout: QMI core error: Transaction timed out’
Some hints would be great
thanks in advance an best regards
