Mobile internet connection broken
-
I generally change the DNS server for the wifi connection using the nmcli command. I have now also tried this for the mobile internet connection. Unfortunately, the result is that I can no longer establish a mobile internet connection at all. Even a supposed reset with nmcli doesn't work. In the settings, an "L" for cellular data is displayed under "SIM 1", but this "L" is missing in the taskbar.
I reinstalled the operating system with the Ubports installer, but unfortunately without success.
Does anyone have any idea how to reset mobile internet settings? Thanks!
