ADSL configuration

Hi, I have a new laptop and try to install the SuSe 15.0 Leap on it. Everything has worked well except the installation of the network connection. I use the networkmanager in KDE.
I have a wired connection (ADSL). I know the hostname, the login name and the password, and have no mechanical problem with the modem or the connections.
I use the same connection with my old laptop with SuSe 13.2 and everithing is OK with it.
But when I’m trying to do the same with this new one there’s no options like DSL or PPP, and now i have no idea what to do.

Could you help me? Thank you so much

Just so you know, the proper name is openSUSE Leap 15.0, not SuSe. Unless, of course, you are referring to SUSE 15.0.

If you’re happy using NetworkManager, then read the following openSUSE guide…

If using wicked, see my old post here…
