Snapd might prevent the Huawei E392 working

[bushido]

I have tried https://krblogs.com/post/62519969772/airtel-4g-lte-on-linux which solution kept me connecting until error and no internet.

When I tried "$ sudo usb_modeswitch -v 12d1 -p 151a -V 12d1 -P 151b -W -M “55534243123456780000000000000011062000000100000000000000000000″" from https://web.archive.org/web/20151020040737/http://blog.bluedrive.ro/?p=28, I got "Take all parameters from the command line

    usb_modeswitch: handle USB devices with multiple modes
    Version 2.6.1 (C) Josua Dietze 2017
    Based on libusb1/libusbx

I have downloaded "usb-modeswitch-data-20191128.tar.bz2", "usb-modeswitch-2.6.0.tar.bz2" and "libusb-1.0.26" but I do not know how to execute any "make" or use these archives via a simple gui.

I use Huawei E392 with Ubuntu 22.04.1 LTS 64-bit (gnome 42.4). I have installed the additional driver suggested by Ubuntu: https://i.stack.imgur.com/3frRp.png.

" journalctl -f" result is at there: https://justpaste.it/8hpuw.
"snap list" result is at there: https://justpaste.it/3pbrj.

I am approaching you via Launcpad as the user "nobody" at https://askubuntu.com/questions/1434952/huawei-e392-is-not-connecting-to-the-internet?noredirect=1#comment2504256_1434952 gave me a hint for it.

I have tried many codes from https://www.google.com/search?q=huawei+e392+ubuntu without any luck. Please suggest any new ideas!
