Prerequisites

Describe the bug

Switchboard crashes while enabling Mobile Broadband on switchboard-plug-network.

To Reproduce

Steps to reproduce the behaviour:

Open up network plugin section in the switchboard.
Connect a modem / dongle. I was using this (Lava product).
After a few moments Dongle / Modem is activated (I had a green LED indicator on the device), the dongle is discovered and the Mobile Broadband section appears.
Click on the toggle button to connect.
Switchboard crashes with segmentation fault.

Expected behaviour

My system connects to the internet via the broadband without any errors.

Screenshots or screen recordings

Crash!

issue

When the Dongle was not activated

Toggle & Highlight Error

Toggle-On / Highlight-Off	Toggle-Off / Highlight-On

Logs

In as seen in the .gif, io.elementary.switchboard crashes with [1] 20213 segmentation fault io.elementary.switchboard.
I tried running gdb io.elementary.switchboard but it ends up saying: Reading symbols from io.elementary.switchboard...(no debugging symbols found)...done.

Platform Information

Screenshot from 2020-04-26 13-27-49

[ ] ~~I'm using the latest version from git that I've manually compiled~~
[X] I'm using the latest released stable version

Additional context

I opened this one as a new issue due to the lack of clarity in #244.
Should this be move to Switchboard?

I am experiencing the same issue, on eOS 6 Here's my setup. Screenshot from 2021-05-14 12-52-24@2x Disabling ModemManager with systemd enables me to get into network settings, but that's not really ideal.

I'm having a very similar issue in Odin (stable release). I can use my LTE modem without any problems but I was not able to configure it using Switchboard's Network plugin because when the modem is plugged to the laptop, I'm not even able to open the Network plugin. Switchboard will close right away. On the other hand if I remove the modem from the USB port I can access Switchboard's Network plugin without any issues. As a workaround I configured the LTE connection using Network Manager's nm-connection-editor.

Starting and stopping the LTE connection from wingpanel's network indicator works just fine.

I tried to run io.elementary.switchboard from the terminal and these are the errors I get when trying to open the Network plugin while the LTE modem is plugged-in:

The issue is dragged on to Odin too and no fix yet.
