currently wrestling with a LTE modem, that used to work under Ubuntu, but refuses to work under Debian 11.

the missing piece:
# add this file & reboot
vim /etc/udev/rules.d/77-mm-huawei-configuration.rules
ACTION=="add|change", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="12d1", ATTR{idProduct}=="15bb", ATTR{bNumConfigurations}=="3", ATTR{bConfigurationValue}!="3" ATTR{bConfigurationValue}="3"
then go to:
- (in this case MATE Desktop) “Advanced Network Configuration” gui program
- add a new broadband connection
- keep the defaults
- when connection setup is finished, go into upper right corner
- click on network symbol and select the just created connection
- it should start connecting (run the while-one-liner as root)
- should show: state: connected
- ping 1.1.1.1; # should work
- run a benchmark 🙂
- Telekom LTE speeds are “okayish” but no where from perfect
