Mobile internet connection broken

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?

@ma

did you try ipv4.method and ipv6.method ? on my phone these parameters are set to 'auto'.

ma

@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.
