i have recently upgraded my wwan modem from the sierra wireless MC 7355 to the 7455.
with this new modem, "mmcli --scan-modems " shows nothing. there’s no sign of this modem in lspci or lsusb.
my system is using Debian GNU/Linux 10, and modemmanager worked fine with the MC7355.
what do i need to do to get modemmanager to use the MC7455?
not sure if it helps, but here is my dmesg:
full.txt (71.8 KB)
So I was doing something similar today.
Is /etc/apt/sources.list already with “main contrib non-free” on all of those? If not go there with gedit, nano or vi, emacs, whatever, and make all of the sources * main contrib non-free*
My adapter is usb, already knew it was realtek so I just went on and after adding the non-free, and then made apt install realtek-firmware… (after an update)
Try usb tethering/cableing to search the sierra firmware.

Got this list here: https://linuxdicasesuporte.blogspot.com/2016/06/instalar-driver-wireless-no-debian.html
Was it already working before the change?
main contrib non-free
is already in my sources.list.
the Sierra Wireless 7355 (the old wwan card) worked flawlessly with modemmanager. i assumed the 7455 (the card i upgraded to) would be similar enough to use the same drivers and software.
i dont need a USB tether, my laptop has a wlan card i can use for internet until my wwan card gets working. problem is: my laptop is very rarely around reliable WiFi, it would be a much better solution to use LTE wwan.
i couldnt find any sierra firmware in debian’s repos. i guess the drivers for my old card are included with debian?
looking closely at my dmesg, it seems to me that this is due to a bug in my motherboard’s firmware.
does anybody know how one could go about fixing, or working around this?
