Implement PPPoE support

Mobile Broadband is also greyed-out.
Perhaps we should install additional packages?

Sergiu, I have also this problem and I am very angry about it. I've been working with Kubuntu since Gutsy Gibbon and was very satisfied with that. But since I have upgraded from Intrepid to Jaunty I can't reach internet, because someone have canceled the option to proceed alternative by using terminal comand pppoeconf. The result is following:

dietmar@dietmar-desktop:~$ sudo pppoeconf
[sudo] password for dietmar:

So, my opinion is, you have no chance for solve this problem untill the MOTU regognized this. I have "tilt" the jaunty and have reinstalled the intrepid. There is also this damned network-manager, but you can work with the terminal.

No update on this bug? Kubuntu Jaunty network manager does not allow to set DSL connection (it is grayed out). At the same time, Ubuntu Jaunty network manager works like a charm. At another box I have both ubuntu-desktop and kubuntu-desktop in the same installation. And you know what? DSL settings are easily accessible when you in are in GNOME session, but there is no way to connect to PPPoE in KDE. And this is release version, stable kubuntu!

I'm testing Karmic Alpha3,
mobile broadband and DSL, these tabs are greyed-out still.
I think this should be fix in Kubuntu 9.10. It has been an hateful issue for so long...

Yes ,I have also this problem . DSL setting is accessible in GNOME ,but cannot connect under KDE environment . at first, I thought my Kubuntu Home disk space isn't enough ,but I understand there just a release problem . It isn't convenient for me switch between GNOME and KDE . I hope can solve it sooner or later.

I can confirm that this problem remains in the release version of Kubuntu 9.04 with only the regular packages installed. The "DSL" and "Mobile-broadband" tabs are greyed out in the network management plasmoid.

I tried installing the backports to get KDE 4.3, but the problem remains (and it's still as annoying).

As a workaround, PPPOE connections can still be established using pppoeconf and pon/poff/plog, but it's a pain in the ass to do this using the command line every time I plug in my laptop to my pppoe connection.

The problem is: using pppoeconf is not a solution. There are some problems with pppd in 9.04, so executing pon complains on some version conflict, and it won't work as in 8.04 with autoconnection. I remember that configuring pppoe in 9.04 was quite painful, much more painful than in any previous ubuntu version I've tested (starting since 6.06). I had a lot of trouble with that, until I've installed kde3 remix.

Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at: https://bugs.kde.org/show_bug.cgi?id=204170

Thank you!I will hear from you soon!

I has been a while since this bug was reported and the networkmanager has been updated much since then and the KDE bugs report states that a fix is release.please upgrade to the most recent version and let us know if you are still having this issue. Thanks in advance.
