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!

did you try the reset parameters function under Access point name in the cellular settings ?
-
Yes, I've tried this several times without success.
Obviously the cellular connection settings (TYPE cdma) are not allowed to be changed using nmcli. The commands " nmcli c modify ... ipv4.dns "" " and " ipv4.ignore-auto-dns no " do not restore the default settings maybe because they have been deleted.
Does anyone know where these settings are stored? Maybe I have a backup.
-
@ma For testing: Did you go into airplane mode then reactivate? Have you turned off cellular data and then reactivated it?
-
did you try ipv4.method and ipv6.method ? on my phone these parameters are set to 'auto'.
-
@gpatel-fr Yes, I did, but that doesn't help.
The problem may be because the "TYPE" has changed from "gsm" to "cdma" and the network setting is no longer recognized as a mobile internet connection.
As a test, I inserted the SIM card into the second slot and there was an internet connection with the same name. The TYPE is gsm.
I can't change the TYPE of the broken connection to gsm. And I don't know if it makes sense to delete the broken connection.

you mean that then you have 2 connections with the same name ? if you delete the bad connection, restart the phone, insert the Sim back in the first slot, then it should recreate it no ?
-
@gpatel-fr I assume so too. But I'm unsure if it's a good idea to delete the faulty connection. I'm afraid that this will affect the functioning connection.
-
@gpatel-fr Yes, there are two connections with the same name (web.vodafone.de).

you can delete by uuid:
nmcli c del --help Usage: nmcli connection delete { ARGUMENTS | help } ARGUMENTS := [id | uuid | path] <ID>, ... Delete connection profiles. The profiles are identified by their name, UUID or D-Bus path. -
@gpatel-fr Great! It works again. Thanks!

The takeaway is that you should not change the DNS server for the mobile internet connection using nmcli.
